Question

我正在测试的函数返回None或Some(ObjectOfSignupEmail)。在我的测试案例中，我想匹配返回的值为Some(ArgumentMatchers.any[SignupEmail])，但出现错误

Expected :Some(null)
Actual   :Some(SignupEmail(Welcome,Test<mailrobot@test.com>,<a href=https://localhost:9000/test/ws/users/signup/11111111-1111-1111-1111-111111111111>Click here to verify email</a>))

如果我将代码更改为signupEmailOption mustBe Some(expectedAnswer)，其中expectedAnswer是SignupEmail的实例，则测试通过。

为什么ArgumentMatchers.any在Some内部不起作用？

这不起作用

"createEmailMessageForUserToken for all correct parameters" should {
    "return Some(email)" in {

      val mailConfig = Map("signupUrl"-> "/test/ws/users/signup/",
        "signupFrom"->"Test<mailrobot@test.com>",
        "signupReply"->"Test<noreply@test.com>",
        "signupSubject"->"Welcome")
      val mailerConfig = Map(
        "host" -> "localhost", // (mandatory). The domain of mail server i.e. the server is responsible for sending/receiving emails for this domain
        "port" -> "9000",
        "tlsRequired" -> "yes"
      )
      val newConfig = Map("mail"->mailConfig,
        "play.mailer"->mailerConfig)
      val newConfiguration = Configuration.from(newConfig)
      val testEnv = new TestEnv(newConfiguration)

      val signupEmailOption:Option[SignupEmail] = testEnv.controller.createEmailMessageForUserToken(testEnv.userToken)

       signupEmailOption mustBe Some(ArgumentMatchers.any(SignupEmail.getClass()))
    }


  }

这有效

 "createEmailMessageForUserToken for all correct parameters" should {
    "return Some(email)" in {

      val mailConfig = Map("signupUrl"-> "/test/ws/users/signup/",
        "signupFrom"->"Test<mailrobot@test.com>",
        "signupReply"->"Test<noreply@test.com>",
        "signupSubject"->"Welcome")
      val mailerConfig = Map(
        "host" -> "localhost", // (mandatory). The domain of mail server i.e. the server is responsible for sending/receiving emails for this domain
        "port" -> "9000",
        "tlsRequired" -> "yes"
      )
      val newConfig = Map("mail"->mailConfig,
        "play.mailer"->mailerConfig)
      val newConfiguration = Configuration.from(newConfig)
      val testEnv = new TestEnv(newConfiguration)

      val url = "https://" + mailerConfig("host") + ":" + mailerConfig("port") + mailConfig("signupUrl") + testEnv.userToken.tokenId
      val html =s"<a href=${url}>Click here to verify email</a>"
      //println("html is "+html)
      val expectedAnswer = SignupEmail(mailConfig("signupSubject"),mailConfig("signupFrom"),html)
      println("expected answer would be "+expectedAnswer)

      val signupEmailOption:Option[SignupEmail] = testEnv.controller.createEmailMessageForUserToken(testEnv.userToken)
      signupEmailOption mustBe Some(expectedAnswer)

 //          signupEmailOption mustBe Some(ArgumentMatchers.any(SignupEmail.getClass()))
    }


  }

Answer 1

您必须使用Scalatest匹配器而不是Mockito匹配器来完成

您正在混合概念，模拟匹配器应在存根模拟方法的参数中使用，如果要声明对测试对象的调用结果，则必须使用测试框架提供的匹配器（Scalatest in我的情况就是您的情况），因此基本上检查this页面上的mustBe和Options的文档。

提示：如果要检查option内的内容的类型，可以使用部分函数匹配器并编写类似

的内容

signupEmailOption should matchPattern { case Some(_: SignupEmail) => }

Answer 2

一些选择。

signupEmailOption should not be None

signupEmailOption should not be empty

signupEmailOption shouldBe defined

signupEmailOption should matchPattern { case Some(_) => }

inside(signupEmailOption) { case Some(_) => }

这些都是等效的。

但是您在做什么-signupEmailOption shouldBe Some(expectedAnswer)实际上是所有中最好的选择。这是正确的事情。就这样保持它。

注意：should*和must*断言几乎是同一回事，它们仅取决于您混入的DSL特性。
