Added self to environment wrapper.
The reason busted usually doesn't need to add mock, spy, stub and s is they make it global.
Made s (Say) a package, that is inlined and also used by LibAssert
Initialized Say earlier this fixed the Assert test error.
All tests in the sample addon now succeed, need to build failure cases into them to verify failure and messaging.
Test All works and succeeds 1st time.
Individual tests succeed 1st time.
Running any test after a test has already been run results in an error.  reloading ui will allow another test to be run.  Need to track down and fix.
