Variable substitution for go.testFlags

[hovsater]

It would be nice if go.testFlags would allow variable substation. This could be really useful when passing custom arguments to go test.

I'm currently working in a project where we need to pass -config ${workspaceRoot}/test-config.yml before running the test suite.

I can see that we already support ~ and ${workspaceRoot} in go.gopath and go.toolsGopath. Addressed in #768.

Is this something we'd like to implement? If so, I'd be happy to take a stab at it. 😃

While we could do this in the extension, I would ideally like this support in the form of an API from VS Code.

Give me a few days and I'll see if we can get this support from VS Code. If not, then I'll add a comment here and you can give it a try.

Sound ok?

@ramya-rao-a sounds good. If it is possible to support this via an API, would we want to update the current implementation for go.gopath and go.toolsGopath to use that as well?

[ramya-rao-a]

yes

This feature is now out in the latest update to the Go extension (0.6.81)
