Full parameterized tests support #649

This PR adds full parameterized test support across the extension:

test-matching

  • upgrade to the jest-editor-support@28.1 to pick up the parser fix for full parameterized test syntax support
  • the matching logic is enhanced to handle parameterized describe blocks, in addition to parameterized test blocks. All parameterized test results are exposed to the rest of the system.

decorators

  • all flavor of parameterized tests should show (computed) test status in the gutter
  • all parameterized test errors will be marked with decorators, therefore, a parameterized test block might have multiple error decorators or a single line might have multiple error messages.

diagnosis

  • all parameterized test errors show up in the PROBLEMS area as well as hovering messages. Each with the full test name.

debug

  • If there are multiple debuggable tests for the given test block, DebugCodeLens display the number of debuggable tests and will ask the user to choose which test to debug.
  • run-test command API change (backward compatible)
  • optimization: remove stop/start the internal jest tests process during debugging. (see the open question below)

Open Questions

  • I was surprised to see that we stop and restart jest process in JestExt.runTest. Looks like this logic was there since runTest is introduced (debugger support #172). Could not see any discussion about why that was needed... Concern that it could be a very expensive overhead especially for large projects. I tried without stop/start logic and all seem fine. So I figure unless we knew the explicit use case to justify the overhead, it is better to leave them out...

Notes

  • There is a known issue in jest that parameterized tests have incorrect locations (Location for test.each results is always 42,9 jestjs/jest#10412). The fix (Fix location for test.each jestjs/jest#10413) was merged in jest-26.5.0. Therefore, the minimal jest version for projects with parameterized tests should be >= 26.5.0
  • to eat our own dog food, I have added a few parameterized tests in our own test suites. You can build the extension with this PR to try out.
  • This PR does touch quite a few files, but most are not too complicated. I have tested this for a couple of days, but more tests especially from different platforms will be needed. Hopefully, we can release this soon so more people can help testing it.

fixes #427 (see comments)

@CzBuCHi looks like you wrote the original debugger support (#172), if you have some time, would be great for you to review this PR as we do have some question about the stop/restart the jest process in JestExt.runTest

@stephtr would love to have you review this PR as well.

@stephtr looks like you are busy...

I ran with this PR last week, and it seems solid, pretty handy actually, as I started to add more parameterized tests... At this point, I think it's probably better to merge it and cut an alpha release so we can start the field testing/fixing cycle sooner... thoughts?

Sorry for the delay
I had just a quick shallow look at it and tested v4 alpha 3, great work! 😃

* @param fileName
* @param testIds test name/pattern.
* Because a test block can have multiple test results, such as for paramertized tests (i.e. test.each/describe.each), there could be multiple debuggable candidates, thus it takes multiple test identifiers.
* Noite: If a test id is a string array, it should represent the hierarchiical relationship of a test structure, such as [describe-id, test-id].

Let's add a space after "Debug"?

Is "Debug n failing tests"/"Debug failing test" too long? -- Edit: In some cases that doesn't make sense. It's better to stick to the "Debug (n)" approach.

How about an uppercase "Select"?

@stephtr better late than never 😉 ... I will address those in another PR
