Before:
  call ale#assert#SetUpLinterTest('typescript', 'tslint')
  call ale#test#SetFilename('test.ts')

After:
  call ale#assert#TearDownLinterTest()

Execute(The default tslint command should be correct):
  AssertLinterCwd '%s:h'
  AssertLinter 'tslint', ale#Escape('tslint') . ' --format json %t'

Execute(The rules directory option should be included if set):
  let b:ale_typescript_tslint_rules_dir = '/foo/bar'

  AssertLinter 'tslint',
  \ ale#Escape('tslint') . ' --format json'
  \   . ' -r ' . ale#Escape('/foo/bar')
  \   . ' %t'

Execute(The executable should be configurable and escaped):
  let b:ale_typescript_tslint_executable = 'foo bar'

  AssertLinter 'foo bar', ale#Escape('foo bar') . ' --format json %t'
