Review of unit tests

http://kyle.barnhart.ca/2012/11/webvtt-unit-test-review.html

Cue Generic Settings (csgeneric_unittest.cpp)

Changes

MultipleCueSettings2Mixed
Used "cue-settings/2-cue-settings-0x20.vtt".
Changed to "cue-settings/2-cue-settings-mixed.vtt".
SameCueSetting
It does not throw an error (WEBVTT_VERTICAL_ALREADY_SET).
The settings are parsed in order so that the right most (last in the
list) one is used.
Vertical will be right to left.
BadDelimiter
It does not throw an error (WEBVTT_EXPECTED_WHITESPACE).
WEBVTT_EXPECTED_WHITESPACE is wrong anyway, it should have been
WEBVTT_VERTICAL_BAD_VALUE because the parser takes everything to the
right of the first colon in a setting.
The parser should try to use "vertical" as keyword and "lr;line:50%" as
value.
It should skip the malformed setting.
BadDelimiter2
It does not throw an error (WEBVTT_EXPECTED_WHITESPACE).
The parser does not require a spacing character between cue end time
timestamp and settings. However there cannot be four digits in a row
after the cue end time timestamp decimal.
It should skip the malformed setting ("^line").
Line should be "auto" because that is default.
NoDelimiter
It does not throw an error (WEBVTT_EXPECTED_WHITESPACE).
The parser does not require a spacing character between cue end time
timestamp and settings.
It should parse the line setting normally.
Added

DigitDelimiter
Essentially the same as making sure the fractions of a second in a
timestamp does not have 4 digits.
Since parser does note require a delimiter between cue end time
timestamp and settings, a possible malformed setting could have a
keyword that starts with a digit.
This should throw the error WEBVTT_MALFORMED_TIMESTAMP.

Cue Setting Align (csalign_unittest.cpp)

The default value for align is middle. If a malformed setting is
encountered it is ignored. If a setting is used more than once the right
most setting (last in the token list) will be used.
Changed

NoKeyword
It does not throw an error (WEBVTT_INVALID_CUESETTING).
It should skip the malformed setting.
Align should be middle because that is default.
BadValue

It should skip the malformed setting.
Align should be middle because that is default.
NoValue
It does not throw an error (WEBVTT_INVALID_CUESETTING).
It should skip the malformed setting.
Align should be middle because that is default.
NoDelimiter
It does not throw an error (WEBVTT_INVALID_CUESETTING).

Added

UppercaseKeyword
Setting keywords are case-sensitive and must be lowercase.
Align should be middle because that is default.
UppercaseValue
Setting values are case-sensitive and must be lowercase.
Align should be middle because that is default.
BadKeyword
Make sure align is "middle" when no valid align setting.

Cue Setting Line (csline_unittest.cpp)

The setting position affect two thing: the line position and the
snap-to-lines flag. The default value for line position is the string
"auto". The default value for snap-to-lines is true.

I made sure error count was 0 for all tests that should pass.
Changed

SingleDigitNegativeLowBoundary
Negative zero equals zero so zero is used.
DoubleDigitNegativeLowBoundary
Negative zero equals zero so zero is used.
BadValue
It does not throw an error (WEBVTT_LINE_BAD_VALUE).
It should skip the malformed setting.
Line should be "auto" and snap-to-lines should be true because that is
default.
BadDelimiter

It should skip the malformed setting.
Line should be "auto" and snap-to-lines should be true because that is
default.
BadKeyword

It should skip the malformed setting.

default.
BadValueSuffix
Actually test two settings.
It does not throw an error (WEBVTT_LINE_BAD_VALUE).
It should skip the malformed settings.
Line should be "auto" and snap-to-lines should be true because that is
default.
WhitespaceDelimiter
Actually test two settings.

default.
BadWhitespaceBeforeDelimiter

It does not throw an error (WEBVTT_INVALID_CUESETTING).
It should skip the malformed settings.
Line should be "auto" and snap-to-lines should be true because that is
default.
BadWhitespaceAfterDelimiter

It does not throw an error (WEBVTT_INVALID_CUESETTING).
It should skip the malformed settings.
Line should be "auto" and snap-to-lines should be true because that is
default.

Removed

tc4015-cue_settings_line_08_bad.test
Not used.
Cue Setting Size (cssize_unittest.cpp)

The default size is 100%. The max is 100% and the min is 0%.

The tests are identical to the cue setting position test, so I copied
those tests and edited as needed. Most of it  has changed and the
changes are similar to the cue setting position changes and additions.
