GoCoverage not working

[mpiexec]

What did you do? (required: The issue will be closed when not provided)

Running :GoCoverage shows message vim-go: no test files available, at the same time :GoTest complete successfully with :GoTest. However :GoCoverageBrowser working correctly.

What did you expect to happen?

vim-go tutorial:

It parses the lines from the profile and then dynamically changes the syntax of your source code to reflect the coverage.

What happened instead?

That message indicates that there are no test files in your package.

[mpiexec]

@bhcleek Ok, but test file main_test.go is there. These commands complete successfully:

:GoTest
:GoTestCompile
:GoCoverageBrowser

Results:

vim-go: [test] SUCCESS
vim-go: [compile test] SUCCESS

Manually running tests:

~> go test -v
=== RUN   Test__sum
--- PASS: Test__sum (0.00s)
PASS
ok      mymod   0.258s

[bhcleek]

Can you run :lcd expand('%:p:h')? After that, I'd like to know the output of these two commands: :echo glob('*_test.go') and :!ls *_test.go

[mpiexec]

Yep,

:echo glob('*_test.go')
" empty
:!ls *_test.go
" main_test.go

[mpiexec]

Maybe you mean that:

:echo ('*_test.go')
" *_test.go

[bhcleek]

The problem seems to be that Vim's glob function is not matching your test file, but I'm not sure why.

What's the full path to your main_test.go file?

[mpiexec]

~> pwd
/Users/grant/tmp/go
~> ll *go
-rw-r--r-- 1 grant staff 712 2023-01-17 17:24 main.go
-rw-r--r-- 1 grant staff 166 2023-01-17 16:11 main_test.go

But it works when I move my project into /Users/grant/go, strange things

[bhcleek]

That makes sense. It's because your wildignore is causing vim's glob() to ignore everything below a tmp directory.

[mpiexec]

It's because your wildignore is causing vim's glob() to ignore everything below a tmp directory.

Bingo! Big thanks
