code lens: support running and debugging tests that use http://labix.org/gocheck

[ramya-rao-a]

Tests that use the check package can be run as part of the whole package or file but not individually in VS Code.

This feature request is to support the below for individual tests using the check package in VS Code

• Go: Test function at cursor command
• Run Tests codelens
• Debug Tests codelens

For more, including hints on how to go about this, please see microsoft/vscode-go#1921 & microsoft/vscode-go#3222

I would be curious to know how many people want this change before we implement it. Please upvote #111 (comment) if you would use this feature.

Similarly, there have been mentions on Slack of the code lenses not working with Testify-based tests.

[ramya-rao-a]

Code lens support for testify based tests was added in microsoft/vscode-go#1707. So, if they are not working anymore, that is a regression.

I worked on an initial implementation. It was closed during the migration to the golang org. It's no longer in sync with master but might be a good starting off point for someone.

microsoft/vscode-go#3222

I'll try to get back to it and open the PR here because its a feature that I would really like to have, but if someone gets to it first I will not be offended.

@tgturner Thanks. Do you have any thought on my comment in #228 (comment)?

I opened a duplicate issue here: #274

Like I mentioned in that issue, it would be nice to either:

• make this code generic and allow for configuration overrides OR
• make this code extensible such that any third-party test suites need to be implemented separated e.g. testify, check.v1 and any future test suites

That way VS Code Go isn't discouraging developers from building new or different test suites packages due to lack of tooling.

If that sounds like overkill, I'm happy to extend the existing code to include check.v1

EDIT: I created a small fork that should solve this for folks running into issues YMMV https://github.com/tylfin/vscode-go-check

[jcalabro]

Hi all! I've opened a PR here for review (it simply extends the existing code to support check.v1, not any other test suites at this time). Thanks!

#1494

We hoped that we stop supporting third-party test libraries and move away from the GoDocumentSymbolProvider. The underlying tool for GoDocumentSymbolProvider is in maintenance mode and this go extension uses gopls document symbol providers. The third-party test code lens support is one of few remaining cases that are blocking deprecation.

Have you considered a separate, specialized extension for users who want to use all those test frameworks? If necessary, the extension can invoke the document symbol provider command and can create a code lens that invokes go extension's commands to run/debug tests too.

With test discovery moving to gopls, this will need to be handled there.
