Before:
  Save g:ale_go_go111module

  call ale#assert#SetUpLinterTest('go', 'gosimple')
  call ale#test#SetFilename('../test-files/go/testfile2.go')

After:
  unlet! b:ale_go_go111module

  call ale#assert#TearDownLinterTest()

Execute(The default gosimple command should be correct):
  AssertLinterCwd '%s:h'
  AssertLinter 'gosimple', 'gosimple .'

Execute(The gosimple command should support Go environment variables):
  let b:ale_go_go111module = 'on'

  AssertLinter 'gosimple', ale#Env('GO111MODULE', 'on') . 'gosimple .'
