coldfusion - 使用 MXUnit 模拟/ stub 组件

Question

我有一个名为 ComponentUnderTest.cfc 的组件，看起来像:

<cfcomponent output="false">
<cfset externalComponent = Component("Externalcomponent");

  <cffunction name="FunctionUnderTest" access="public"...>
     <cfset externalComponent.ExternalFunction()> 
  </cffunction>
</cfcomponent>

如何在 MXUnit 测试组件中模拟/ stub externalComponent.externFunction():

<cfcomponent displayname="ComponentTester" extends="mxunit.framework.TestCase>

 <cffunction name="MockForExternalFunction">
   .....
 </cffunction>
 ??????
 <cffunction name=TestComponent>
     <cfset componentUnderTest = CreateObject("ComponentUnderTest")>
     ?????
     <cfset componentUnderTest.FunctionUnderTest()>  <!--- should call MockForExternalFunction --->
 </cffunction>
</cfcomponent>

您将不得不将模拟组件注入(inject) componentUnderTest替换现有的。

你可以这样做:

// I took this lot from the docs Henry pointed you to: I'm not familiar with MXUnit's mocking framework, but this sounds right
mockedObjectWithMockedMethod = mock();
mockedObjectWithMockedMethod.ExternalFunction().returns(MockForExternalFunction());

function injectVariable(name, value){
    variables[name] = value;
}
componentUnderTest.injectVariable = injectVariable;
componentUnderTest.injectVariable("externalComponent", mockedObjectWithMockedMethod);

MockForExternalFunction()只是提供了 ExternalFunction()时要返回的返回值被调用，而不是调用 ExternalFunction()。不过，这应该没问题。
