:GoTest sometimes on error opens file that not exists, with only one line: "package <my-package-name>" about vim-go

[vitaly-zdanevich]

Looks like I found the root cause: my file name was interfaces.go but vim-go was opening interface.go - renaming of the file looks like fix it, but better to open not an interface file but test file on concrete line...

Vim-go gets the filename to put in the quickfix (and therefore the file to location to jump to) from the test failure. What's the output of go test in this case?

With interfaces.go filename, I got this (cut related places):

That go test output indicates that the filename is interface.go and that the error is on line 74.

[vitaly-zdanevich]

Yes, interesting... Looks like we need to rename a few of our files - drop s at the end...

[bhcleek]

I don't think you need to rename anything. I think the problem is in gomock, but I'm not quite sure what it is. The interface.go file that go test is referring to is /home/vitaly/p/ri/svi/serv/pkg/crave/client/mocks/interface.go. It's just a coincidence that you also have a file named interfaces.go.
