我有界面
Interface MyInterface {
myMethodToBeVerified (String, String);
}
接口的实现是
class MyClassToBeTested implements MyInterface {
myMethodToBeVerified(String, String) {
…….
}
}
我还有一门课
class MyClass {
MyInterface myObj = new MyClassToBeTested();
public void abc(){
myObj.myMethodToBeVerified (new String("a"), new String("b"));
}
}
我正在尝试为 MyClass 编写 JUnit.我已经完成了
I am trying to write JUnit for MyClass. I have done
class MyClassTest {
MyClass myClass = new MyClass();
@Mock
MyInterface myInterface;
testAbc(){
myClass.abc();
verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}
}
但是我得到 mockito 想要但没有被调用,实际上在验证调用时与这个 mock 的交互为零.
谁能提出一些解决方案.
can anyone suggest some solutions.
你需要在你正在测试的类中注入 mock.目前,您正在与真实对象进行交互,而不是与模拟对象进行交互.您可以通过以下方式修复代码:
You need to inject mock inside the class you're testing. At the moment you're interacting with the real object, not with the mock one. You can fix the code in a following way:
void testAbc(){
myClass.myObj = myInteface;
myClass.abc();
verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}
虽然将所有初始化代码提取到 @Before
although it would be a wiser choice to extract all initialization code into @Before
@Before
void setUp(){
myClass = new myClass();
myClass.myObj = myInteface;
}
@Test
void testAbc(){
myClass.abc();
verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}
这篇关于例外:mockito 想要但没有被调用,实际上与这个 mock 的交互为零的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
