Before:
  Save b:ale_go_gometalinter_executable
  Save b:ale_go_gometalinter_options

  let b:ale_go_gometalinter_executable = 'gometalinter'

  runtime ale_linters/go/gometalinter.vim

  call ale#test#SetDirectory('/testplugin/test/command_callback')
  call ale#test#SetFilename('test.go')

After:
  Restore

  call ale#test#RestoreDirectory()
  call ale#linter#Reset()

Execute(The gometalinter callback should return the right defaults):

  AssertEqual

  \   . ' --include=''^' . expand('%:p') . '.*$'''
  \   . ' ' . ale#Escape(getcwd()),

Execute(The gometalinter callback should use a configured executable):
  let b:ale_go_gometalinter_executable = 'something else'

  AssertEqual

  AssertEqual

  \   . ' ' . ale#Escape(getcwd()),

Execute(The gometalinter callback should use configured options):
  let b:ale_go_gometalinter_options = '--foobar'
