  INTRODUCTION<br>
  This&nbsp;test&nbsp;plan&nbsp;addresses&nbsp;debugging&nbsp;test&nbsp;coverage&nbsp;for&nbsp;the&nbsp;2.x&nbsp;series&nbsp;of&nbsp;<br>
  IronPython&nbsp;interpreter&nbsp;releases.<br>
  &nbsp;<br>
  EDITORS&nbsp;NOTES<br>
  Throughout&nbsp;this&nbsp;document&nbsp;you&nbsp;will&nbsp;find&nbsp;references&nbsp;to&nbsp;documentation&nbsp;in<br>
  other&nbsp;packages&nbsp;similar&nbsp;to&nbsp;"See&nbsp;documentation&nbsp;for&nbsp;debugging.pdb_module".&nbsp;&nbsp;This&nbsp;simply<br>
  means&nbsp;that&nbsp;relative&nbsp;to&nbsp;this&nbsp;package&nbsp;(i.e.,&nbsp;debugging),&nbsp;you&nbsp;should&nbsp;follow<br>

  FEATURE&nbsp;GOALS<br>
  The&nbsp;goals&nbsp;of&nbsp;IP's&nbsp;debugging&nbsp;feature&nbsp;is&nbsp;to&nbsp;provide&nbsp;IronPython&nbsp;users&nbsp;with&nbsp;<br>
  complete&nbsp;use&nbsp;of&nbsp;CPython's&nbsp;existing&nbsp;debugger&nbsp;functionality,&nbsp;the&nbsp;"pdb"&nbsp;and<br>
  "bdb"&nbsp;modules&nbsp;respectively,&nbsp;while&nbsp;also&nbsp;providing&nbsp;a&nbsp;great&nbsp;interactive&nbsp;debugging&nbsp;<br>
  experience&nbsp;using&nbsp;Microsoft&nbsp;tools&nbsp;such&nbsp;as&nbsp;mdbg&nbsp;and&nbsp;the&nbsp;Visual&nbsp;Studio&nbsp;IDE.<br>
  &nbsp;<br>
  -------------------------------------------------------------------------------<br>
  PRIMARY&nbsp;TESTING&nbsp;CONCERNS<br>
  -&nbsp;new&nbsp;builtin&nbsp;module&nbsp;attributes&nbsp;added&nbsp;to&nbsp;IP&nbsp;to&nbsp;support&nbsp;CPython's&nbsp;"bdb"&nbsp;and&nbsp;"pdb"<br>
  &nbsp;&nbsp;modules<br>
  -&nbsp;compatibility&nbsp;with&nbsp;CPython's&nbsp;use&nbsp;of&nbsp;the&nbsp;"bdb"&nbsp;and&nbsp;"pdb"&nbsp;modules<br>
  -&nbsp;what&nbsp;happens&nbsp;breakpoint-wise&nbsp;when&nbsp;IP&nbsp;steps&nbsp;into&nbsp;.NET&nbsp;code&nbsp;from&nbsp;"pdb"?<br>
  -&nbsp;.NET&nbsp;applications&nbsp;hosting&nbsp;IP&nbsp;should&nbsp;be&nbsp;able&nbsp;to&nbsp;debug&nbsp;Python&nbsp;code<br>
  -&nbsp;the&nbsp;experience&nbsp;of&nbsp;debugging&nbsp;IP&nbsp;under&nbsp;Microsoft's&nbsp;mdbg&nbsp;and&nbsp;Visual&nbsp;<br>
  &nbsp;&nbsp;Studio&nbsp;tools&nbsp;is&nbsp;what&nbsp;existing&nbsp;CSharp&nbsp;and&nbsp;VB.Net&nbsp;would&nbsp;expect;&nbsp;but&nbsp;still<br>
  &nbsp;&nbsp;Pythonic<br>
  -&nbsp;"-D"&nbsp;command-line&nbsp;flag<br>
  &nbsp;<br>
  -------------------------------------------------------------------------------<br>
  PRIMARY&nbsp;TESTING&nbsp;FOCUS<br>
  Our&nbsp;principal&nbsp;testing&nbsp;focus&nbsp;will&nbsp;be&nbsp;on&nbsp;testing&nbsp;that&nbsp;IP's&nbsp;support&nbsp;of&nbsp;the<br>
  "pdb"&nbsp;module&nbsp;is&nbsp;completely&nbsp;compatible&nbsp;with&nbsp;that&nbsp;of&nbsp;CPython&nbsp;by&nbsp;running&nbsp;existing<br>
  CPython&nbsp;tests,&nbsp;and&nbsp;also&nbsp;by&nbsp;creating&nbsp;a&nbsp;new&nbsp;generic&nbsp;side-by-side&nbsp;testing&nbsp;framework.<br>
  &nbsp;<br>
  The&nbsp;secondardy&nbsp;focus&nbsp;will&nbsp;be&nbsp;testing&nbsp;that&nbsp;debugging&nbsp;IP&nbsp;under&nbsp;mdbg&nbsp;is&nbsp;a<br>
  pleasant&nbsp;experience.&nbsp;&nbsp;This&nbsp;will&nbsp;initially&nbsp;be&nbsp;acheived&nbsp;by&nbsp;using&nbsp;the&nbsp;CLR&nbsp;Team's<br>
  existing&nbsp;debugging&nbsp;test&nbsp;framework,&nbsp;but&nbsp;in&nbsp;the&nbsp;long&nbsp;run&nbsp;we&nbsp;will&nbsp;move&nbsp;to&nbsp;a<br>
  new&nbsp;generic,&nbsp;side-by-side&nbsp;testing&nbsp;framework&nbsp;which&nbsp;can&nbsp;be&nbsp;reused&nbsp;for&nbsp;other&nbsp;<br>
  side-by-side&nbsp;testing&nbsp;areas.<br>

  SCOPE&nbsp;OF&nbsp;TEST&nbsp;CASES<br>
  We'll&nbsp;be&nbsp;getting&nbsp;most&nbsp;of&nbsp;our&nbsp;test&nbsp;coverage&nbsp;on&nbsp;the&nbsp;debugging&nbsp;feature&nbsp;of&nbsp;<br>
  IP&nbsp;by&nbsp;unit&nbsp;testing&nbsp;the&nbsp;CPython&nbsp;'pdb'&nbsp;module.&nbsp;&nbsp;Doing&nbsp;this&nbsp;thoroughly<br>
  should&nbsp;guarantee&nbsp;we&nbsp;hit&nbsp;nearly&nbsp;all&nbsp;blocks&nbsp;of&nbsp;code&nbsp;supporting&nbsp;debugging&nbsp;in&nbsp;<br>
  IP&nbsp;DLLs.&nbsp;This&nbsp;will&nbsp;be&nbsp;validated&nbsp;and&nbsp;verified&nbsp;through&nbsp;monthly&nbsp;code&nbsp;<br>
  coverage&nbsp;runs.&nbsp;&nbsp;As&nbsp;an&nbsp;aside,&nbsp;this&nbsp;should&nbsp;in&nbsp;theory&nbsp;hit&nbsp;most&nbsp;of&nbsp;the&nbsp;DLR's<br>
  Microsoft.Scripting.Debugging.dll&nbsp;as&nbsp;well.<br>
  &nbsp;<br>
  As&nbsp;IP&nbsp;currently&nbsp;has&nbsp;no&nbsp;tie-in&nbsp;into&nbsp;the&nbsp;Visual&nbsp;Studio&nbsp;IDE,&nbsp;this&nbsp;is&nbsp;<br>
  arguably&nbsp;far&nbsp;less&nbsp;important&nbsp;to&nbsp;test&nbsp;than&nbsp;our&nbsp;support&nbsp;of&nbsp;the&nbsp;'pdb'&nbsp;module&nbsp;or&nbsp;<br>
  even&nbsp;mdbg.&nbsp;&nbsp;As&nbsp;a&nbsp;result,&nbsp;the&nbsp;Microsoft&nbsp;toolset&nbsp;testing&nbsp;emphasis&nbsp;will&nbsp;involve<br>
  exahaustively&nbsp;covering&nbsp;all&nbsp;aspects&nbsp;of&nbsp;mdbg.&nbsp;That&nbsp;said,&nbsp;some&nbsp;of&nbsp;our&nbsp;users&nbsp;do&nbsp;in<br>
  fact&nbsp;have&nbsp;VS&nbsp;Pro&nbsp;installed&nbsp;implying&nbsp;that&nbsp;we&nbsp;should&nbsp;perform&nbsp;at&nbsp;least&nbsp;minimal,<br>
  manual&nbsp;sanity&nbsp;tests&nbsp;before&nbsp;every&nbsp;major&nbsp;public&nbsp;release&nbsp;of&nbsp;IP.&nbsp;&nbsp;Should&nbsp;we<br>
  ever&nbsp;provide&nbsp;visualizers&nbsp;for&nbsp;our&nbsp;debug&nbsp;symbols&nbsp;we'll&nbsp;need&nbsp;much&nbsp;more&nbsp;<br>
  comprehensive&nbsp;and&nbsp;automated&nbsp;tests&nbsp;for&nbsp;VS&nbsp;of&nbsp;course.<br>

  -------------------------------------------------------------------------------<br>
  ACCEPTANCE&nbsp;CRITERIA<br>
  -&nbsp;no&nbsp;debugging&nbsp;related&nbsp;feature&nbsp;should&nbsp;be&nbsp;checked&nbsp;into&nbsp;the&nbsp;internal&nbsp;source&nbsp;<br>

  &nbsp;&nbsp;&nbsp;&nbsp;-&nbsp;at&nbsp;least&nbsp;half&nbsp;of&nbsp;all&nbsp;bugs&nbsp;opened&nbsp;on&nbsp;the&nbsp;feature&nbsp;since&nbsp;its&nbsp;inception&nbsp;are<br>

  KEY&nbsp;FEATURE&nbsp;ISSUES<br>
  -&nbsp;no&nbsp;spec&nbsp;on&nbsp;debugging&nbsp;IP&nbsp;from&nbsp;mdbg,&nbsp;VS,&nbsp;or&nbsp;what&nbsp;debugging&nbsp;symbols&nbsp;<br>
  &nbsp;&nbsp;should&nbsp;be&nbsp;generated&nbsp;for&nbsp;various&nbsp;Python&nbsp;constructs<br>
  -&nbsp;insufficient&nbsp;test&nbsp;resources&nbsp;to&nbsp;adequately&nbsp;test&nbsp;this&nbsp;feature<br>
  -&nbsp;insufficient&nbsp;resources&nbsp;to&nbsp;implement&nbsp;all&nbsp;debugging&nbsp;features&nbsp;called&nbsp;out&nbsp;in&nbsp;this<br>

  &nbsp;<br>
  -------------------------------------------------------------------------------<br>
  TEST&nbsp;APPROACH<br>
  -&nbsp;DESIGN&nbsp;VALIDATION<br>
  &nbsp;&nbsp;&nbsp;&nbsp;We&nbsp;have&nbsp;no&nbsp;part&nbsp;in&nbsp;the&nbsp;design&nbsp;of&nbsp;the&nbsp;"pdb"&nbsp;and&nbsp;"bdb"&nbsp;standard&nbsp;modules.&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;As&nbsp;for&nbsp;debugging&nbsp;under&nbsp;mdbg...there&nbsp;is&nbsp;no&nbsp;current&nbsp;design&nbsp;document&nbsp;on&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;debugging&nbsp;Python&nbsp;sessions.&nbsp;&nbsp;Generally&nbsp;speaking&nbsp;test&nbsp;will&nbsp;simply&nbsp;ensure&nbsp;that<br>
  &nbsp;&nbsp;&nbsp;&nbsp;whatever&nbsp;mdbg&nbsp;functionality&nbsp;exists&nbsp;with&nbsp;regard&nbsp;to&nbsp;IP&nbsp;is&nbsp;"Pythonic",<br>
  &nbsp;&nbsp;&nbsp;&nbsp;but&nbsp;at&nbsp;the&nbsp;same&nbsp;time&nbsp;familiar&nbsp;to&nbsp;CSharp&nbsp;and&nbsp;VB&nbsp;developers.<br>
  &nbsp;<br>
  -&nbsp;DATA&nbsp;VALIDATION<br>
  &nbsp;&nbsp;&nbsp;&nbsp;pdb/bdb:&nbsp;at&nbsp;a&nbsp;very&nbsp;low-level,&nbsp;all&nbsp;we&nbsp;need&nbsp;to&nbsp;validate&nbsp;is&nbsp;that&nbsp;parameters&nbsp;passed<br>
  &nbsp;&nbsp;&nbsp;&nbsp;to&nbsp;a&nbsp;trace&nbsp;function&nbsp;we&nbsp;set&nbsp;via&nbsp;sys.settrace&nbsp;are&nbsp;as&nbsp;expected.&nbsp;&nbsp;In&nbsp;particular,<br>
  &nbsp;&nbsp;&nbsp;&nbsp;the&nbsp;first&nbsp;parameter&nbsp;passed&nbsp;in&nbsp;is&nbsp;the&nbsp;current&nbsp;stack&nbsp;frame&nbsp;which&nbsp;we&nbsp;have&nbsp;a&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;very&nbsp;solid&nbsp;chance&nbsp;of&nbsp;getting&nbsp;wrong.<br>
  &nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;mdbg/VS:&nbsp;need&nbsp;to&nbsp;validate&nbsp;that&nbsp;generation&nbsp;of&nbsp;PDB&nbsp;symbols&nbsp;"make&nbsp;sense"<br>
  &nbsp;&nbsp;&nbsp;&nbsp;with&nbsp;respect&nbsp;to&nbsp;whatever&nbsp;Python&nbsp;source&nbsp;is&nbsp;being&nbsp;compiled.&nbsp;There&nbsp;are&nbsp;at&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;least&nbsp;two&nbsp;ways&nbsp;to&nbsp;accomplish&nbsp;this:<br>
  &nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;Create&nbsp;a&nbsp;regression&nbsp;test&nbsp;in&nbsp;which&nbsp;we&nbsp;compare&nbsp;the&nbsp;generated&nbsp;PDB&nbsp;of&nbsp;a&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;known&nbsp;Python&nbsp;script&nbsp;to&nbsp;an&nbsp;expected&nbsp;PDB&nbsp;file.&nbsp;&nbsp;The&nbsp;Python&nbsp;script&nbsp;should<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;exhaustively&nbsp;cover&nbsp;everything&nbsp;that's&nbsp;possible&nbsp;in&nbsp;the&nbsp;Python&nbsp;grammar.<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Testing&nbsp;in&nbsp;this&nbsp;manner&nbsp;is&nbsp;not&nbsp;really&nbsp;maintainable&nbsp;in&nbsp;the&nbsp;long&nbsp;run&nbsp;as&nbsp;we<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;expect&nbsp;the&nbsp;PDB&nbsp;generated&nbsp;for&nbsp;a&nbsp;given&nbsp;Python&nbsp;script&nbsp;to&nbsp;change&nbsp;over&nbsp;time<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;reflecting&nbsp;optimizations&nbsp;and&nbsp;new&nbsp;features&nbsp;added&nbsp;to&nbsp;IP<br>
  &nbsp;&nbsp;&nbsp;&nbsp;2.&nbsp;Test&nbsp;that&nbsp;the&nbsp;behavior&nbsp;of&nbsp;mdbg,&nbsp;given&nbsp;a&nbsp;known&nbsp;Python&nbsp;script,&nbsp;does&nbsp;not&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;regress.&nbsp;&nbsp;Again,&nbsp;this&nbsp;Python&nbsp;script&nbsp;should&nbsp;exhaustively&nbsp;cover&nbsp;everything<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;that's&nbsp;possible&nbsp;in&nbsp;Python's&nbsp;grammar,&nbsp;but&nbsp;this&nbsp;time&nbsp;around&nbsp;we'll&nbsp;also<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;need&nbsp;to&nbsp;cover&nbsp;everything&nbsp;that's&nbsp;possible&nbsp;under&nbsp;mdbg<br>
  &nbsp;<br>
  -&nbsp;API&nbsp;TESTING<br>
  &nbsp;&nbsp;&nbsp;&nbsp;We'll&nbsp;exhaustively&nbsp;cover&nbsp;the&nbsp;entire&nbsp;"pdb"&nbsp;standard&nbsp;module&nbsp;without&nbsp;ever&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;touching&nbsp;the&nbsp;CSharp&nbsp;APIs&nbsp;directly.&nbsp;&nbsp;Prior&nbsp;coverage&nbsp;runs&nbsp;have&nbsp;shown&nbsp;that&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;(generally&nbsp;speaking)&nbsp;any&nbsp;block&nbsp;of&nbsp;code&nbsp;that&nbsp;is&nbsp;not&nbsp;directly&nbsp;hittable&nbsp;through&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;the&nbsp;Python&nbsp;API&nbsp;is&nbsp;likely&nbsp;dead&nbsp;code.&nbsp;&nbsp;Also,&nbsp;testing&nbsp;"bdb"&nbsp;module&nbsp;is&nbsp;lower&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;priority&nbsp;as&nbsp;"pdb"&nbsp;uses&nbsp;this&nbsp;for&nbsp;its&nbsp;own&nbsp;implementation.&nbsp;&nbsp;The&nbsp;final&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;justification&nbsp;for&nbsp;this&nbsp;is&nbsp;that&nbsp;there&nbsp;is&nbsp;actually&nbsp;very&nbsp;little&nbsp;in&nbsp;terms&nbsp;of&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;debugging&nbsp;APIs&nbsp;in&nbsp;IP&nbsp;DLLs.&nbsp;&nbsp;Most&nbsp;of&nbsp;the&nbsp;debugging&nbsp;support&nbsp;is&nbsp;built<br>
  &nbsp;&nbsp;&nbsp;&nbsp;directly&nbsp;into&nbsp;the&nbsp;DLR's&nbsp;Microsoft.Scripting.Debugging.dll.<br>
  &nbsp;&nbsp;&nbsp;&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;For&nbsp;mdbg/VS,&nbsp;we'll&nbsp;exhaustively&nbsp;cover&nbsp;all&nbsp;mdbg&nbsp;commands.<br>
  &nbsp;&nbsp;&nbsp;&nbsp;<br>
  -&nbsp;CONTENT&nbsp;TESTING<br>
  &nbsp;&nbsp;All&nbsp;debugging&nbsp;documentation&nbsp;should&nbsp;be&nbsp;thoroughly&nbsp;reviewed&nbsp;by&nbsp;Test&nbsp;before&nbsp;any<br>
  &nbsp;&nbsp;public&nbsp;release&nbsp;of&nbsp;IronPython.&nbsp;&nbsp;Careful&nbsp;attention&nbsp;will&nbsp;be&nbsp;given&nbsp;to&nbsp;duplicating<br>
  &nbsp;&nbsp;exactly&nbsp;any&nbsp;command&nbsp;fed&nbsp;into&nbsp;ipy.exe&nbsp;or&nbsp;mdbg.exe,&nbsp;and&nbsp;this&nbsp;should&nbsp;be&nbsp;<br>
  &nbsp;&nbsp;automated&nbsp;entirely&nbsp;if&nbsp;feasible.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;LOW-RESOURCE&nbsp;TESTING<br>
  &nbsp;&nbsp;Use&nbsp;of&nbsp;the&nbsp;debugging&nbsp;feature&nbsp;has&nbsp;a&nbsp;few&nbsp;side&nbsp;effects&nbsp;which&nbsp;might&nbsp;be&nbsp;interesting<br>
  &nbsp;&nbsp;from&nbsp;a&nbsp;limited&nbsp;resources&nbsp;perspective.&nbsp;&nbsp;First&nbsp;and&nbsp;foremost,&nbsp;use&nbsp;of&nbsp;the&nbsp;-X:Frames<br>
  &nbsp;&nbsp;and&nbsp;-X:FullFrames&nbsp;IP&nbsp;console&nbsp;flags&nbsp;imply&nbsp;that&nbsp;IP&nbsp;will&nbsp;consume&nbsp;more&nbsp;<br>
  &nbsp;&nbsp;memory&nbsp;than&nbsp;under&nbsp;normal&nbsp;circumstances.&nbsp;&nbsp;We&nbsp;should&nbsp;check&nbsp;that&nbsp;IP&nbsp;does&nbsp;not&nbsp;<br>
  &nbsp;&nbsp;consume&nbsp;"too&nbsp;much"&nbsp;extra&nbsp;memory.&nbsp;&nbsp;Next,&nbsp;use&nbsp;of&nbsp;the&nbsp;debugging&nbsp;flag,&nbsp;'-D',&nbsp;in<br>
  &nbsp;&nbsp;conjunction&nbsp;with&nbsp;the&nbsp;'-X:SaveAssemblies'&nbsp;flag&nbsp;will&nbsp;generate&nbsp;<br>
  &nbsp;&nbsp;Snippets.debug.scripting.pdb&nbsp;in&nbsp;the&nbsp;%TMP%&nbsp;directory.&nbsp;What&nbsp;occurs&nbsp;if&nbsp;the&nbsp;drive<br>
  &nbsp;&nbsp;containing&nbsp;%TMP%&nbsp;is&nbsp;full?<br>
  &nbsp;<br>
  &nbsp;&nbsp;NOTE:&nbsp;while&nbsp;this&nbsp;is&nbsp;an&nbsp;interesting&nbsp;test&nbsp;area&nbsp;to&nbsp;explore,&nbsp;there&nbsp;are&nbsp;no&nbsp;current<br>
  &nbsp;&nbsp;plans&nbsp;to&nbsp;test&nbsp;it.&nbsp;&nbsp;We&nbsp;should&nbsp;perform&nbsp;general&nbsp;low-resource&nbsp;testing&nbsp;of&nbsp;<br>
  &nbsp;&nbsp;IP&nbsp;before&nbsp;tackling&nbsp;it&nbsp;for&nbsp;this&nbsp;specific&nbsp;feature.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;SETUP&nbsp;TESTING<br>
  &nbsp;&nbsp;The&nbsp;only&nbsp;option&nbsp;of&nbsp;IP's&nbsp;MSI&nbsp;installer&nbsp;capable&nbsp;of&nbsp;affecting<br>
  &nbsp;&nbsp;the&nbsp;debugging&nbsp;feature&nbsp;is&nbsp;the&nbsp;ability&nbsp;to&nbsp;selectively&nbsp;install&nbsp;CPython's&nbsp;standard<br>
  &nbsp;&nbsp;library.&nbsp;&nbsp;As&nbsp;we&nbsp;generate&nbsp;the&nbsp;list&nbsp;of&nbsp;CPython&nbsp;modules&nbsp;to&nbsp;include&nbsp;in&nbsp;the&nbsp;MSI<br>
  &nbsp;&nbsp;dynamically,&nbsp;it&nbsp;would&nbsp;be&nbsp;worthwhile&nbsp;to&nbsp;always&nbsp;check&nbsp;that&nbsp;pdb.py&nbsp;is&nbsp;included.<br>
  &nbsp;&nbsp;<br>
  &nbsp;&nbsp;NOTE:&nbsp;IronPython&nbsp;currently&nbsp;has&nbsp;no&nbsp;automated&nbsp;tests&nbsp;for&nbsp;the&nbsp;MSI.&nbsp;Once&nbsp;we<br>
  &nbsp;&nbsp;do,&nbsp;we&nbsp;need&nbsp;to&nbsp;add&nbsp;a&nbsp;check&nbsp;to&nbsp;ensure&nbsp;pdb.py&nbsp;is&nbsp;always&nbsp;included.&nbsp;&nbsp;For&nbsp;the&nbsp;time<br>
  &nbsp;&nbsp;being&nbsp;this&nbsp;will&nbsp;have&nbsp;to&nbsp;be&nbsp;done&nbsp;manually.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;MODES&nbsp;AND&nbsp;RUNTIME&nbsp;OPTIONS<br>
  &nbsp;&nbsp;We&nbsp;should&nbsp;focus&nbsp;our&nbsp;efforts&nbsp;on&nbsp;testing&nbsp;IP&nbsp;with&nbsp;the&nbsp;following&nbsp;modes:<br>
  &nbsp;&nbsp;*&nbsp;-D&nbsp;-X:Frames<br>
  &nbsp;&nbsp;*&nbsp;-D&nbsp;-X:FullFrames<br>
  &nbsp;&nbsp;*&nbsp;-D&nbsp;-X:Frames&nbsp;-X:SaveAssemblies<br>
  &nbsp;&nbsp;*&nbsp;-D<br>
  &nbsp;&nbsp;*&nbsp;-X:Frames<br>
  &nbsp;&nbsp;*&nbsp;<br>
  &nbsp;&nbsp;using&nbsp;both&nbsp;debug&nbsp;and&nbsp;release&nbsp;IP&nbsp;assemblies.&nbsp;&nbsp;Also&nbsp;note&nbsp;that&nbsp;this<br>
  &nbsp;&nbsp;needs&nbsp;to&nbsp;be&nbsp;performed&nbsp;for&nbsp;both&nbsp;Python&nbsp;interactive&nbsp;sessions&nbsp;and&nbsp;Python&nbsp;scripts<br>
  &nbsp;&nbsp;passed&nbsp;into&nbsp;ipy.exe&nbsp;(e.g.,&nbsp;"ipy.exe&nbsp;test_str.py").&nbsp;&nbsp;Last&nbsp;but<br>
  &nbsp;&nbsp;not&nbsp;least,&nbsp;there's&nbsp;the&nbsp;%PYTHONDEBUG%&nbsp;environment&nbsp;variable&nbsp;to&nbsp;consider.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;INTEROPERABILITY<br>
  &nbsp;&nbsp;Of&nbsp;primary&nbsp;concern&nbsp;is&nbsp;that&nbsp;IP&nbsp;produces&nbsp;an&nbsp;identical&nbsp;experience&nbsp;as<br>
  &nbsp;&nbsp;CPython&nbsp;when&nbsp;given&nbsp;input&nbsp;which&nbsp;utilizes&nbsp;the&nbsp;pdb&nbsp;module.&nbsp;This&nbsp;will&nbsp;be&nbsp;<br>
  &nbsp;&nbsp;accomplished&nbsp;via&nbsp;side-by-side&nbsp;testing&nbsp;and&nbsp;verification&nbsp;that&nbsp;the&nbsp;output&nbsp;of&nbsp;<br>
  &nbsp;&nbsp;IP&nbsp;is&nbsp;the&nbsp;same&nbsp;as&nbsp;CPython&nbsp;given&nbsp;an&nbsp;identical&nbsp;input.<br>
  &nbsp;&nbsp;<br>
  &nbsp;&nbsp;We&nbsp;will&nbsp;also&nbsp;verify&nbsp;that&nbsp;IP&nbsp;can&nbsp;be&nbsp;debugged&nbsp;from&nbsp;mdbg&nbsp;and&nbsp;the&nbsp;Visual<br>
  &nbsp;&nbsp;Studio&nbsp;IDE.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;INTEGRATION&nbsp;TESTING<br>

  &nbsp;&nbsp;*&nbsp;breaking&nbsp;into&nbsp;Python&nbsp;code&nbsp;from&nbsp;IronRuby<br>
  &nbsp;<br>
  -&nbsp;BETA&nbsp;TESTING<br>
  &nbsp;&nbsp;The&nbsp;second&nbsp;beta&nbsp;release&nbsp;of&nbsp;IronPython&nbsp;2.6&nbsp;will&nbsp;support&nbsp;the&nbsp;debugging&nbsp;feature<br>
  &nbsp;&nbsp;in&nbsp;the&nbsp;form&nbsp;of&nbsp;very&nbsp;limited&nbsp;pdb&nbsp;module&nbsp;support&nbsp;with&nbsp;the&nbsp;-X:Frames&nbsp;flag&nbsp;<br>
  &nbsp;&nbsp;passed&nbsp;to&nbsp;ipy.exe.&nbsp;As&nbsp;with&nbsp;all&nbsp;beta&nbsp;releases&nbsp;of&nbsp;IP,&nbsp;this&nbsp;will&nbsp;be&nbsp;<br>
  &nbsp;&nbsp;released&nbsp;on&nbsp;CodePlex&nbsp;to&nbsp;the&nbsp;general&nbsp;public.&nbsp;We&nbsp;will&nbsp;then&nbsp;use&nbsp;feedback<br>
  &nbsp;&nbsp;from&nbsp;the&nbsp;IronPython&nbsp;Community&nbsp;to&nbsp;determine&nbsp;the&nbsp;amount&nbsp;of&nbsp;effort&nbsp;that&nbsp;goes&nbsp;<br>
  &nbsp;&nbsp;into&nbsp;fully&nbsp;testing&nbsp;this&nbsp;feature.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;ENVIRONMENT/SYSTEM&nbsp;-&nbsp;GENERAL<br>
  &nbsp;&nbsp;The&nbsp;%PYTHONDEBUG%&nbsp;environment&nbsp;variable&nbsp;may&nbsp;have&nbsp;some&nbsp;impact&nbsp;on&nbsp;this&nbsp;feature.<br>
  &nbsp;&nbsp;Other&nbsp;than&nbsp;this,&nbsp;the&nbsp;VS&nbsp;IDE&nbsp;will&nbsp;of&nbsp;course&nbsp;need&nbsp;to&nbsp;be&nbsp;installed&nbsp;for&nbsp;testing<br>
  &nbsp;&nbsp;the&nbsp;VS&nbsp;debugging&nbsp;experience.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;CONFIGURATION<br>
  &nbsp;&nbsp;Need&nbsp;.NET&nbsp;2.0&nbsp;Service&nbsp;Pack&nbsp;1&nbsp;installed&nbsp;to&nbsp;run&nbsp;IP,&nbsp;and&nbsp;.NET&nbsp;3.5<br>
  &nbsp;&nbsp;Service&nbsp;Pack&nbsp;1&nbsp;to&nbsp;build&nbsp;the&nbsp;feature.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;USER&nbsp;INTERFACE<br>
  &nbsp;&nbsp;IP&nbsp;provides&nbsp;no&nbsp;user&nbsp;interfaces.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;PERFORMANCE&nbsp;&amp;&nbsp;CAPACITY&nbsp;TESTING<br>
  &nbsp;&nbsp;Minimally,&nbsp;we&nbsp;need&nbsp;to&nbsp;run&nbsp;one&nbsp;or&nbsp;more&nbsp;tests&nbsp;in&nbsp;the&nbsp;perf&nbsp;lab&nbsp;under&nbsp;the&nbsp;-X:Frames<br>
  &nbsp;&nbsp;and&nbsp;-X:FullFrames&nbsp;test&nbsp;modes.&nbsp;&nbsp;We&nbsp;should&nbsp;also&nbsp;measure&nbsp;the&nbsp;end-to-end&nbsp;run&nbsp;time<br>
  &nbsp;&nbsp;of&nbsp;a&nbsp;complete,&nbsp;yet&nbsp;minimal,&nbsp;debugging&nbsp;sample&nbsp;utilizing&nbsp;the&nbsp;pdb&nbsp;module&nbsp;in&nbsp;the&nbsp;<br>
  &nbsp;&nbsp;lab.&nbsp;&nbsp;The&nbsp;focus&nbsp;here&nbsp;will&nbsp;simply&nbsp;be&nbsp;on&nbsp;ensuring&nbsp;there&nbsp;are&nbsp;no&nbsp;perf&nbsp;regressions<br>
  &nbsp;&nbsp;which&nbsp;are&nbsp;greater&nbsp;than&nbsp;15%&nbsp;for&nbsp;any&nbsp;given&nbsp;checkin,&nbsp;and&nbsp;also&nbsp;that&nbsp;overall&nbsp;<br>
  &nbsp;&nbsp;performance&nbsp;of&nbsp;the&nbsp;debugging&nbsp;feature&nbsp;remains&nbsp;palatable&nbsp;to&nbsp;our&nbsp;userbase.<br>
  &nbsp;&nbsp;<br>
  &nbsp;&nbsp;In&nbsp;terms&nbsp;of&nbsp;capacity&nbsp;testing&nbsp;we&nbsp;should&nbsp;look&nbsp;at:<br>
  &nbsp;&nbsp;-&nbsp;if&nbsp;perf&nbsp;gets&nbsp;affected&nbsp;when&nbsp;breaking&nbsp;into&nbsp;deeply&nbsp;nested&nbsp;functions&nbsp;(e.g.,&nbsp;<br>

  &nbsp;&nbsp;so,&nbsp;does&nbsp;IP&nbsp;disclose&nbsp;the&nbsp;existence&nbsp;of&nbsp;this&nbsp;file?<br>
  &nbsp;&nbsp;Is&nbsp;remote&nbsp;debugging&nbsp;supported?&nbsp;If&nbsp;so,&nbsp;what&nbsp;safeguards&nbsp;are&nbsp;in&nbsp;place?<br>
  &nbsp;&nbsp;<br>
  -&nbsp;RELIABILITY<br>
  &nbsp;&nbsp;Most&nbsp;end-users&nbsp;are&nbsp;expected&nbsp;to&nbsp;enter&nbsp;into&nbsp;debugging&nbsp;sessions&nbsp;for&nbsp;short&nbsp;<br>
  &nbsp;&nbsp;periods&nbsp;of&nbsp;time&nbsp;to&nbsp;diagnose&nbsp;issues&nbsp;with&nbsp;Python&nbsp;code.&nbsp;&nbsp;From&nbsp;this&nbsp;perspective<br>
  &nbsp;&nbsp;the&nbsp;so-called&nbsp;"up&nbsp;time"&nbsp;of&nbsp;debugging&nbsp;sessions&nbsp;is&nbsp;less&nbsp;important&nbsp;than&nbsp;the&nbsp;<br>
  &nbsp;&nbsp;overall&nbsp;sporadic&nbsp;failure&nbsp;frequency.&nbsp;We&nbsp;can&nbsp;get&nbsp;a&nbsp;good&nbsp;sense&nbsp;of&nbsp;how&nbsp;often&nbsp;<br>
  &nbsp;&nbsp;sporadic&nbsp;failures&nbsp;occur&nbsp;by&nbsp;automatically&nbsp;running&nbsp;debugging&nbsp;tests&nbsp;in&nbsp;SNAP&nbsp;<br>

  -&nbsp;INTERNATIONAL&nbsp;ISSUES<br>
  &nbsp;&nbsp;As&nbsp;Python&nbsp;is&nbsp;not&nbsp;a&nbsp;localized&nbsp;language&nbsp;and&nbsp;available&nbsp;only&nbsp;in&nbsp;English,&nbsp;we&nbsp;<br>
  &nbsp;&nbsp;simply&nbsp;need&nbsp;to&nbsp;confirm&nbsp;that&nbsp;nothing&nbsp;gets&nbsp;localized.&nbsp;&nbsp;This&nbsp;can&nbsp;be&nbsp;done&nbsp;by<br>
  &nbsp;&nbsp;running&nbsp;a&nbsp;simple&nbsp;debugbing&nbsp;test&nbsp;against&nbsp;non-English&nbsp;OSes&nbsp;such&nbsp;as&nbsp;Deutsche<br>
  &nbsp;&nbsp;Vista.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;ROBUSTNESS<br>
  &nbsp;&nbsp;We'll&nbsp;need&nbsp;a&nbsp;dedicated&nbsp;test&nbsp;or&nbsp;two&nbsp;in&nbsp;the&nbsp;stress&nbsp;lab&nbsp;to&nbsp;ensure&nbsp;there&nbsp;are&nbsp;no<br>
  &nbsp;&nbsp;memory&nbsp;leaks.&nbsp;&nbsp;Also,&nbsp;we'll&nbsp;need&nbsp;to&nbsp;keep&nbsp;an&nbsp;eye&nbsp;out&nbsp;for&nbsp;sporadic&nbsp;failures&nbsp;of<br>
  &nbsp;&nbsp;debugging&nbsp;tests&nbsp;in&nbsp;SNAP.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;ERROR&nbsp;TESTING<br>
  &nbsp;&nbsp;What&nbsp;happens&nbsp;when&nbsp;invalid&nbsp;commands&nbsp;are&nbsp;fed&nbsp;to&nbsp;the&nbsp;pdb&nbsp;debugger?&nbsp;Is&nbsp;this&nbsp;<br>
  &nbsp;&nbsp;handled&nbsp;identically&nbsp;to&nbsp;CPython?<br>
  &nbsp;&nbsp;<br>
  &nbsp;&nbsp;Is&nbsp;there&nbsp;any&nbsp;conceivable&nbsp;way&nbsp;to&nbsp;fully&nbsp;break&nbsp;debugging&nbsp;without&nbsp;actually&nbsp;<br>
  &nbsp;&nbsp;breaking&nbsp;ipy.exe&nbsp;in&nbsp;general?&nbsp;&nbsp;What&nbsp;happens&nbsp;under&nbsp;the&nbsp;mode&nbsp;<br>
  &nbsp;&nbsp;"-D&nbsp;-X:SaveAssemblies"&nbsp;when&nbsp;the&nbsp;current&nbsp;user&nbsp;doesn't&nbsp;have&nbsp;write&nbsp;<br>

  &nbsp;&nbsp;removed&nbsp;outright?<br>
  &nbsp;&nbsp;<br>
  -&nbsp;USABILITY<br>
  &nbsp;&nbsp;There&nbsp;are&nbsp;three&nbsp;major&nbsp;usability&nbsp;issues&nbsp;with&nbsp;debugging:<br>
  &nbsp;&nbsp;*&nbsp;IP&nbsp;offers&nbsp;no&nbsp;visualizer&nbsp;for&nbsp;the&nbsp;VS&nbsp;IDE<br>
  &nbsp;&nbsp;*&nbsp;we're&nbsp;largely&nbsp;incompatible&nbsp;with&nbsp;CPython's&nbsp;pdb&nbsp;module<br>
  &nbsp;&nbsp;*&nbsp;debugging&nbsp;Python&nbsp;code&nbsp;from&nbsp;.NET&nbsp;apps&nbsp;isn't&nbsp;currently&nbsp;possible<br>
  &nbsp;&nbsp;<br>
  &nbsp;&nbsp;Test&nbsp;will&nbsp;depend&nbsp;on&nbsp;feedback&nbsp;from&nbsp;the&nbsp;IronPython&nbsp;Mailing&nbsp;List&nbsp;and&nbsp;blogs&nbsp;to<br>
  &nbsp;&nbsp;determine&nbsp;more&nbsp;usability&nbsp;issues.&nbsp;Resource&nbsp;permitting,&nbsp;we&nbsp;may&nbsp;also&nbsp;do&nbsp;<br>
  &nbsp;&nbsp;app&nbsp;building&nbsp;exercises.<br>
  &nbsp;&nbsp;<br>
  &nbsp;&nbsp;The&nbsp;usability&nbsp;goal&nbsp;of&nbsp;this&nbsp;feature&nbsp;is&nbsp;that&nbsp;there&nbsp;are&nbsp;no&nbsp;complaints&nbsp;about<br>
  &nbsp;&nbsp;the&nbsp;IP&nbsp;debugging&nbsp;experience&nbsp;from&nbsp;our&nbsp;users.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;ACCESSIBILITY<br>
  &nbsp;&nbsp;As&nbsp;this&nbsp;feature&nbsp;provides&nbsp;no&nbsp;new&nbsp;user&nbsp;interfaces&nbsp;to&nbsp;IronPython.&nbsp;and&nbsp;simply&nbsp;<br>
  &nbsp;&nbsp;emits&nbsp;output&nbsp;to&nbsp;the&nbsp;stdout&nbsp;stream&nbsp;of&nbsp;command&nbsp;prompts,&nbsp;there&nbsp;should&nbsp;be&nbsp;no&nbsp;<br>
  &nbsp;&nbsp;need&nbsp;to&nbsp;invest&nbsp;into&nbsp;accessibility&nbsp;testing.<br>
  &nbsp;&nbsp;<br>
  -&nbsp;USER&nbsp;SCENARIOS<br>
  &nbsp;&nbsp;It's&nbsp;anticipated&nbsp;that&nbsp;users&nbsp;of&nbsp;this&nbsp;feature&nbsp;will&nbsp;be&nbsp;limited&nbsp;almost&nbsp;exclusively&nbsp;to<br>
  &nbsp;&nbsp;developers.&nbsp;Expert&nbsp;Python&nbsp;users&nbsp;will&nbsp;likely&nbsp;prefer&nbsp;using&nbsp;the&nbsp;pdb<br>
  &nbsp;&nbsp;module&nbsp;or&nbsp;debugging&nbsp;their&nbsp;applications&nbsp;directly&nbsp;via&nbsp;the&nbsp;"-i"&nbsp;ipy.exe&nbsp;<br>
  &nbsp;&nbsp;option.&nbsp;&nbsp;Existing&nbsp;Microsoft&nbsp;customers&nbsp;with&nbsp;little&nbsp;Python&nbsp;background&nbsp;will&nbsp;<br>
  &nbsp;&nbsp;probably&nbsp;be&nbsp;more&nbsp;comfortable&nbsp;with&nbsp;the&nbsp;VS&nbsp;IDE&nbsp;debugging&nbsp;experience.&nbsp;Due&nbsp;to&nbsp;<br>
  &nbsp;&nbsp;this&nbsp;we&nbsp;must&nbsp;make&nbsp;sure&nbsp;both&nbsp;experiences&nbsp;are&nbsp;great!<br>
  &nbsp;&nbsp;<br>
  &nbsp;&nbsp;The&nbsp;types&nbsp;of&nbsp;applications&nbsp;being&nbsp;debugged&nbsp;will&nbsp;likely:<br>
  &nbsp;&nbsp;*&nbsp;be&nbsp;non-trivial<br>
  &nbsp;&nbsp;*&nbsp;consist&nbsp;of&nbsp;many&nbsp;different&nbsp;modules/packages<br>
  &nbsp;&nbsp;*&nbsp;make&nbsp;heavy&nbsp;use&nbsp;of&nbsp;the&nbsp;CPython&nbsp;standard&nbsp;library&nbsp;and/or&nbsp;third&nbsp;party&nbsp;Python<br>
  &nbsp;&nbsp;&nbsp;&nbsp;packages<br>
  &nbsp;&nbsp;*&nbsp;be&nbsp;debugged&nbsp;often&nbsp;during&nbsp;the&nbsp;application&nbsp;development&nbsp;phase<br>
  &nbsp;&nbsp;*&nbsp;be&nbsp;debugged&nbsp;infrequently&nbsp;in&nbsp;a&nbsp;production&nbsp;environment&nbsp;when&nbsp;something&nbsp;goes&nbsp;<br>
  &nbsp;&nbsp;&nbsp;&nbsp;awry<br>
  &nbsp;&nbsp;<br>
  &nbsp;&nbsp;With&nbsp;these&nbsp;constraints&nbsp;in&nbsp;mind,&nbsp;we&nbsp;should&nbsp;try&nbsp;to&nbsp;debug&nbsp;existing&nbsp;major&nbsp;third<br>
  &nbsp;&nbsp;party&nbsp;Python&nbsp;applications&nbsp;and/or&nbsp;add&nbsp;debugging&nbsp;support&nbsp;to&nbsp;our&nbsp;own&nbsp;internal<br>

  pdb&nbsp;and&nbsp;mdbg&nbsp;tests&nbsp;will&nbsp;be&nbsp;100%&nbsp;automated&nbsp;in&nbsp;SNAP.<br>
  &nbsp;<br>
  &nbsp;<br>
  -------------------------------------------------------------------------------<br>
  MANUAL&nbsp;TESTS<br>
  Setup&nbsp;testing&nbsp;will&nbsp;be&nbsp;manual&nbsp;for&nbsp;now,&nbsp;and&nbsp;we'll&nbsp;eventually&nbsp;move&nbsp;to&nbsp;automated&nbsp;<br>
  testing&nbsp;in&nbsp;SNAP&nbsp;using&nbsp;PowerShell&nbsp;support&nbsp;scripts.<br>
  &nbsp;<br>
  Visual&nbsp;Studio&nbsp;IDE&nbsp;testing&nbsp;is&nbsp;also&nbsp;manual&nbsp;for&nbsp;now.&nbsp;&nbsp;Sometime&nbsp;in&nbsp;the&nbsp;<br>
  future&nbsp;we'll&nbsp;migrate&nbsp;to&nbsp;using&nbsp;the&nbsp;VS&nbsp;team's&nbsp;automation&nbsp;technologies.<br>
  &nbsp;<br>
  Manual&nbsp;testing&nbsp;will&nbsp;only&nbsp;occur&nbsp;for&nbsp;major&nbsp;IP&nbsp;releases&nbsp;and&nbsp;the&nbsp;<br>
  instructions&nbsp;will&nbsp;be&nbsp;documented&nbsp;on&nbsp;the&nbsp;internal&nbsp;IP&nbsp;website&nbsp;under&nbsp;the&nbsp;<br>
  "Release&nbsp;Process"&nbsp;wiki.<br>
  &nbsp;<br>

  -------------------------------------------------------------------------------<br>
  REGRESSION&nbsp;TESTS<br>
  Regression&nbsp;tests&nbsp;will&nbsp;be&nbsp;added&nbsp;to&nbsp;existing&nbsp;test&nbsp;modules&nbsp;under&nbsp;the&nbsp;"debugging"&nbsp;<br>
  package&nbsp;before&nbsp;any&nbsp;CodePlex&nbsp;or&nbsp;internal&nbsp;bug&nbsp;dealing&nbsp;with&nbsp;debugging&nbsp;is&nbsp;closed.<br>
  As&nbsp;such,&nbsp;the&nbsp;majority&nbsp;of&nbsp;these&nbsp;regressions&nbsp;will&nbsp;be&nbsp;automated&nbsp;and&nbsp;run&nbsp;on&nbsp;every<br>
  developer&nbsp;or&nbsp;test&nbsp;checkin.&nbsp;&nbsp;Developers&nbsp;should&nbsp;preferably&nbsp;add&nbsp;a&nbsp;regression&nbsp;test<br>
  for&nbsp;every&nbsp;bug&nbsp;fix,&nbsp;and&nbsp;Test&nbsp;will&nbsp;verify&nbsp;the&nbsp;sufficiency&nbsp;of&nbsp;the&nbsp;test,&nbsp;extending<br>
  it&nbsp;if&nbsp;necessary.<br>
  &nbsp;<br>
  -------------------------------------------------------------------------------<br>
  BUG&nbsp;BASHES<br>
  While&nbsp;considered&nbsp;to&nbsp;be&nbsp;extremely&nbsp;useful,&nbsp;we&nbsp;have&nbsp;no&nbsp;current&nbsp;plans&nbsp;for&nbsp;internal&nbsp;<br>
  bug&nbsp;bashes&nbsp;on&nbsp;this&nbsp;feature.&nbsp;&nbsp;Quite&nbsp;simply&nbsp;put,&nbsp;we&nbsp;need&nbsp;more&nbsp;IronPython&nbsp;headcount&nbsp;<br>
  and/or&nbsp;interest&nbsp;from&nbsp;the&nbsp;rest&nbsp;of&nbsp;Visual&nbsp;Studio&nbsp;Languages&nbsp;to&nbsp;accomplish&nbsp;this.<br>

  Bugs&nbsp;will&nbsp;be&nbsp;triaged&nbsp;on&nbsp;a&nbsp;weekly&nbsp;basis&nbsp;by&nbsp;the&nbsp;entire&nbsp;IronPython&nbsp;Team.<br>
  &nbsp;<br>
  -------------------------------------------------------------------------------<br>
  PLAN&nbsp;CONTINGENCIES<br>
  Without&nbsp;at&nbsp;least&nbsp;one&nbsp;additional&nbsp;SDET&nbsp;or&nbsp;other&nbsp;test&nbsp;tasks&nbsp;getting&nbsp;dropped,&nbsp;only&nbsp;<br>
  phases&nbsp;I&nbsp;and&nbsp;II&nbsp;of&nbsp;this&nbsp;plan&nbsp;are&nbsp;implementable&nbsp;prior&nbsp;to&nbsp;the&nbsp;release&nbsp;of&nbsp;<br>
  IP&nbsp;2.6&nbsp;RTM.<br>
  &nbsp;<br>
  -------------------------------------------------------------------------------<br>
  EXTERNAL&nbsp;DEPENDENCIES<br>
  We&nbsp;depend&nbsp;on&nbsp;the&nbsp;DLR&nbsp;for&nbsp;their&nbsp;implementation&nbsp;of&nbsp;Microsoft.Scripting.Debugging.dll&nbsp;<br>
  which&nbsp;forms&nbsp;the&nbsp;basis&nbsp;of&nbsp;our&nbsp;support&nbsp;of&nbsp;the&nbsp;CPython&nbsp;pdb&nbsp;module.&nbsp;&nbsp;This&nbsp;plan&nbsp;<br>
  assumes&nbsp;that&nbsp;this&nbsp;DLL&nbsp;has&nbsp;been&nbsp;adequately&nbsp;tested.<br>
  &nbsp;<br>
  There&nbsp;are&nbsp;no&nbsp;teams/projects&nbsp;we&nbsp;know&nbsp;about&nbsp;which&nbsp;are&nbsp;taking&nbsp;a&nbsp;dependency&nbsp;on&nbsp;<br>
  IP's&nbsp;debugging&nbsp;functionality.<br>
  &nbsp;<br>
  -------------------------------------------------------------------------------<br>
  HEADCOUNT&nbsp;REQUIREMENTS<br>
  At&nbsp;least&nbsp;two&nbsp;FTE&nbsp;IronPython&nbsp;SDETs&nbsp;will&nbsp;be&nbsp;needed&nbsp;to&nbsp;implement&nbsp;this&nbsp;test&nbsp;plan&nbsp;<br>
  fully:&nbsp;one&nbsp;to&nbsp;handle&nbsp;general,&nbsp;day-to-day&nbsp;IP&nbsp;test&nbsp;operations<br>
  (i.e.,&nbsp;passes/investigations/issues/regressions,&nbsp;etc),&nbsp;and&nbsp;another&nbsp;to&nbsp;work&nbsp;exclusively&nbsp;on&nbsp;the&nbsp;<br>
  debugging&nbsp;feature.&nbsp;&nbsp;A&nbsp;loose&nbsp;approximation&nbsp;is&nbsp;that&nbsp;the&nbsp;SDET&nbsp;working&nbsp;full-time<br>
  on&nbsp;debugging&nbsp;would&nbsp;need&nbsp;anywhere&nbsp;from&nbsp;one&nbsp;to&nbsp;three&nbsp;months&nbsp;to&nbsp;completely&nbsp;<br>
  implement&nbsp;all&nbsp;aspects&nbsp;of&nbsp;this&nbsp;plan.&nbsp;&nbsp;This&nbsp;estimate&nbsp;varies&nbsp;considerably&nbsp;<br>
  depending&nbsp;upon&nbsp;how&nbsp;much&nbsp;emphasis&nbsp;is&nbsp;to&nbsp;be&nbsp;given&nbsp;to&nbsp;pdb&nbsp;versus&nbsp;mdbg&nbsp;versus&nbsp;the&nbsp;<br>
  VS&nbsp;IDE.&nbsp;&nbsp;Having&nbsp;a&nbsp;second&nbsp;full-time&nbsp;SDET&nbsp;on&nbsp;the&nbsp;debugging&nbsp;feature&nbsp;would&nbsp;have&nbsp;a<br>
  not&nbsp;positive&nbsp;effect&nbsp;as&nbsp;the&nbsp;division&nbsp;of&nbsp;labor&nbsp;between&nbsp;testing&nbsp;command-line&nbsp;IP<br>
  debugging&nbsp;support&nbsp;and&nbsp;VS&nbsp;IDE&nbsp;support&nbsp;is&nbsp;quite&nbsp;clear.<br>

  PRODUCT&nbsp;SUPPORT<br>
  IP&nbsp;is&nbsp;not&nbsp;a&nbsp;supported&nbsp;product&nbsp;in&nbsp;the&nbsp;conventional&nbsp;Microsoft&nbsp;sense.&nbsp;<br>
