x/tools/gopls: fails to load package for test file

[dylankb]

VSCode fails to execute commands such as "Go to Definition" while using gopls on my machine for *_test.go files. In other words, it does not reveal the requested source code or preview for the command. Additionally, I see gopls server error logs when I open any of these files in my VSCode editor and when using gopls check. This is not the case in non-test files in the same packages.

What version of Go are you using (go version)?

$ go version
go version go1.14.3 darwin/amd

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

What did you do?

I'm not certain when or if a breakage occurred since other editors are in use on my team, but I can try to reproduce a more minimal example if this information is not enough.

What did you expect to see?

When I navigate to a file I don't expect to see RPC trace errors for the gopls server. For example, navigating to an /internal/db_test.go file. When I navigate to /internal/db.go, I do not see these errors.

// No error when opening /internal/db.go in VSCode

When I clickGo to Definition I expect the editor to navigate to the source code at defined either in the temporary modules cache or a file within the project directory. I also don't expect to see gopls errors in the RPC trace when hovering or clicking Go.

Similarly, I expect gopls check to not return errors for test files - no errors for non-test files.

gopls check /Users/dbarnard/Code/go/src/$MY_PRIVATE_REPO/$MY_PROJECT/internal/db/db.go

What did you see instead?

$ go clean --modcache
$ go mod tidy

When I navigate to an *_test.go file, I see RPC and see trace errors in the gopls server. Here I'm navigating to an /internal/db_test.go file.

Finally, this may be a separate issue but just in case it helps as context -- I seem get this error as a popup from the VSCode Go extension/gopls when I add a new package in my source code and save. Example:

The code in the workspace failed to compile (see the error message below). If you believe this is a mistake, please file an issue: https://github.com/golang/go/issues/new. $MY_PROJECT/internal/routing [$MY_PROJECT/internal/routing.test] has no metadata

Thanks in advance!

[stamblerre]

The second issue you mention is #40690.

The issue with your test file is that gopls can't seem to load any package for it - does it contain build tags by any chance? What is the output of go list -e -json -test ./... when you are in the /Users/dbarnard/Code/go/src/$MY_PRIVATE_REPO/$MY_PROJECT/internal/db/ directory?

[dylankb]

Yes, the test files do use build tags. Should build tags be handled in gopls settings?. Here's the output you requested.

The issue with your test file is that gopls can't seem to load any package for it

Perhaps it's a problem that these files show up as IgnoredGoFiles?

Yes - you have to add build tags to your configuration if you are using a build tagged file.
See https://github.com/golang/tools/blob/master/gopls/doc/settings.md#buildflags-array-of-strings and #29202 for more details.

The setting you want is:

"gopls": {
    "env": {
        "GOFLAGS": "-tags=<my build tag>"
    }
}

Wohoo! Totally fixes my issue. Great project, and I also loved your GopherCon talk. Keep it up!

Thank you! 😄
