Before:
  Save g:ale_go_go111module
  Save b:ale_go_go111module

  let b:ale_go_go111module = ''

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

After:
  Restore

  unlet! b:ale_go_go111module

  call ale#assert#TearDownLinterTest()

Execute(The default gofmt command should be correct):
  AssertLinter 'gofmt',
  \ ale#Escape('gofmt') . ' -e %t'

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

  AssertLinter 'gofmt',
  \ ale#Env('GO111MODULE', 'on')
  \ . ale#Escape('gofmt') . ' -e %t'
