Question

我是spock的新手。我在普通类中创建了模拟对象，它的工作正常。但是当我们像下面的结构那样继承时，我就无法正确地模拟它给出的错误（空指针）。任何人都知道如何在spock中做到这一点。

Class Parent{
    Third getThird(){
        return third;
    }
}

Class Child extend Parent{
    Object method1(){
        String msg=getThird().someMethod(); // need to mock this line
        return object;
    }   
}

given:
    Third third=Mock()
    Child child=new Child()
    child.getThird(false) >> third
    third.someMethod() >>  "xyz"
when :
Object object=child.method1()
then:
//comparing the things

Answer 1

你能试试吗？：

given:
    def third = Mock(Third)
    Child.metaClass.getThird = {
        third
    } 
when :
    Object object=child.method1()
then:
    1 * thirdMocked.someMethod() >> "xyz"
and:
    //comparing the things
cleanup:
    Child.metaClass = null

Answer 2

你可以像任何接口一样在Spock中模拟类：

given:
    def thirdMock = Mock(Third) {
      someMethod() >> "xyz"
    }
    def child = Mock(Child) {
      third >> thirdMock
    }
when :
  def object = child.method1()
then:
  //comparing the things

然而，它通常是代码不能真正测试的症状。在你的情况下，你应该做第三个＆＃39;注射，然后注入模拟。

无法在与spock的继承关系中创建模拟
