我想对以下方法进行单元测试：

def handleEmailSharing = { EmailSharingCommand esc ->
        if (params.send) {
            def recaptchaOK = true
            if (!recaptchaService.verifyAnswer(session, request.getRemoteAddr(), params)) {
                recaptchaOK = false
            }

         }
...

这是我正在尝试的方式：

import com.megatome.grails.RecaptchaService

class EmailSharerControllerTests extends ControllerUnitTestCase {

    protected void setUp() {
     controller.recaptchaService = new RecaptchaService()
   }

void testHandleEmailSharingSendAndSuccess() {
       mockCommandObject(EmailSharingCommand)
        def emailSharingCommand = new EmailSharingCommand(from: "acorrect@emailaddress.fr", 
                                                          to: "   anothercorrect@emailaddress.fr   ,    whichis@notalone.it   ", 
                                                          cc: "", 
                                                          bcc:"someonein@bcc.com.br",
                                                          trimmedListOfToRecipients: ["anothercorrect@emailaddress.fr", "whichis@notalone.it"])
        emailSharingCommand.validate()
}
controller.handleEmailSharing(emailSharingCommand)

但我收到以下错误：

Cannot get property 'recaptcha' on null object
java.lang.NullPointerException: Cannot get property 'recaptcha' on null object

    at bankemist.personalcreditcomparator.EmailSharerControllerTests.testHandleEmailSharingSendButtonButMissingFromAndTo(EmailSharerControllerTests.groovy:49)

这很奇怪，因为它基本上说我的org.codehaus.groovy.grails.commons.ConfigurationHolder 为空，或者它包含的recaptcha 对象。 RecaptchaService.groovy的调用线33是：

if (ConfigurationHolder.config.recaptcha) {...}

或者（最后一个:)）我的 RecaptchaConfig.groovy 是这样设置的：

recaptcha {
    // These keys are generated by the ReCaptcha service
    publicKey = "xxx"
    privateKey = "xxx"

    // Include the noscript tags in the generated captcha
    includeNoScript = true
}

mailhide {
    // Generated by the Mailhide service
    publicKey = ""
    privateKey = ""
}

environments {
  development {
    recaptcha {
      // Set to false to disable the display of captcha
      enabled = true

      // Communicate using HTTPS
      useSecureAPI = false
    }
  }
  test {
    recaptcha {
      // Set to false to disable the display of captcha
      enabled = true

      // Communicate using HTTPS
      useSecureAPI = false
    }
  }

我无法解决这个问题。我试图将 configurationHolder 导入到测试文件中，但它并没有改变任何东西。非常感谢任何帮助。

【解决方案1】：

单元测试将没有 ConfigurationHolder，因为它们不在运行的框架内执行。在单元测试中，最好的选择是模拟 RecaptchaService，所以在你的测试方法中像这样：

def recapMock = mockFor(RecaptchaService)
recapMock.demand.verifyAnswer(1..1) { session, remoteAddr, params ->
     return true // Or false if you want it to fail in your test
}
controller.recaptchaService = recapMock.createMock()
// Then run your test
controller.handleEmailSharing(emailSharingCommand)

【解决方案2】：

您应该注入一个 recaptchaService 并模拟 verifyAnswer 以返回您想要为您的测试用例返回的任何内容。

     def recaptchaServiceMock = mockFor(recaptchaService)

            recaptchaServiceMock.demand.verifyAnswer() {Session session, 
                                                        Map params->
                return true
            }

      currentService.recaptchaService = recaptchaServiceMock.createMock()
