Before:
  Save g:ale_go_go_executable
  Save g:ale_go_govet_options
  call ale#assert#SetUpLinterTest('go', 'govet')

After:
  Restore
  call ale#assert#TearDownLinterTest()

Execute(The default command should be correct):
  AssertLinter 'go', ale#path#CdString(ale#Escape(expand('%:p:h'))) . ' go vet  .'

Execute(Extra options should be supported):
  let g:ale_go_govet_options = '--foo-bar'
  AssertLinter 'go', ale#path#CdString(ale#Escape(expand('%:p:h'))) . ' go vet  --foo-bar .'

Execute(The executable should be configurable):
  let g:ale_go_go_executable = 'foobar'
  AssertLinter 'foobar', ale#path#CdString(ale#Escape(expand('%:p:h'))) . ' foobar vet  .'
