unit-testing - Grails-使用reCaptcha插件对 Controller 的方法进行单元测试

Question

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
            }

         }
...

这就是我试图做到的方式:

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)

但是我收到以下错误:

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null或它包含的 recaptcha对象。 RecaptchaService.groovy的 call 线路33为:

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

或(最后一个:))这是我的RecaptchaConfig.groovy的设置方式:

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
    }
  }

我无法解决此问题。
我试图将configurationHolder导入测试文件，但它不会改变任何内容。任何帮助，不胜感激。

单元测试将没有ConfigurationHolder，因为它们不会在运行的框架内执行。在单元测试中，最好的选择是模拟RecaptchaService，因此在您的测试方法中是这样的:

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)
