Before:
  Save g:ale_js_importjs_executable

  " Use an invalid global executable, so we don't match it.
  let g:ale_js_importjs_executable = 'xxxinvalid'

  call ale#test#SetDirectory('/testplugin/test/fixers')

After:
  Restore

  call ale#test#RestoreDirectory()

Execute(The importjs callback should return 0 when the executable isn't executable):

Execute(The importjs callback should run the command when the executable test passes):

  AssertEqual

  \   'command': ale#Escape(g:ale_js_importjs_executable) . ' fix %s'
  \ },
  \ ale#fixers#importjs#Fix(bufnr(''))

Execute(The ProcessOutput callback should return the expected output):
  let g:testOutput = '{"messages":[],"fileContent":"one\ntwo","unresolvedImports":{}}'

  AssertEqual
  \ ['one', 'two'],
  \ ale#fixers#importjs#ProcessOutput(bufnr(''), g:testOutput)
