Specs2在匿名内部类中的测试类之外运行匹配器

Question

我正在进行以下测试：

class FooTest extends SpecWithJUnit with MockServer {

"Foo" should {
 "fail" in new ctx {

    givenAListenerThatAlwaysFailsWhenExcecuted()
    foo.runMethodThatInvokesAListener
  }
 }
} 

trait MockServer extends BeforeAfterAll with MustMatchers {

  private val wireMockServer = new WireMockServer(wireMockConfig().port(9000))

  def givenAListenerThatAlwaysFailsWhenExcecuted() = {
    val listener = new RequestListener {
    override def requestReceived(request: Request, response: Response): Unit = {
    true must beFalse
  }
}
  wireMockServer.addMockServiceRequestListener(listener)
  listener
}

 override def beforeAll(): Unit = wireMockServer.start()
 override def afterAll(): Unit = wireMockServer.stop()
}

当我运行它时，我在控制台中看到异常，但测试本身并没有失败。我如何让它失败？

Answer 1

您必须使用MustThrownMatchers代替MustMatchers，以便true must beFalse之类的任何失败预期都会被new ctx { ... }抛出。

否则true must beFalse只是一个简单的MatchResult[Boolean]值，可以在匿名ctx类的正文中创建。
