[英]JMockit mock private method in @PostConstruct
In my class under test there is a @PostConstruct
annotated method that invokes another private method. 在我的测试类中,有一个
@PostConstruct
注释方法,该方法调用另一个私有方法。
@PostConstruct
public void init() {
longWork(); // private method
}
JMockit's default behaviour is to execute @PostConstruct
methods of @Tested
classes upon injection. JMockit的默认行为是在注入时执行
@Tested
类的@PostConstruct
方法。
If a @Tested class has a method annotated with javax.annotations.PostConstruct, it should be executed right after injection.
如果@Tested类的方法带有javax.annotations.PostConstruct注释,则应在注入后立即执行。

JMockit calls the init()
method, what I don't want. JMockit调用了我不想要的
init()
方法。
From the thread dump: 从线程转储:
at com.me.Worker.longWork(Worker.java:56)
at com.me.Worker.longWork.init(Worker.java:47)
...
at mockit.internal.util.MethodReflection.invoke(MethodReflection.java:96)
How can that call be mocked/removed/blocked? 该呼叫如何被模拟/删除/阻止?
I tried to mock the init
and longWork
methods as shown below. 我试图模拟
init
和longWork
方法,如下所示。 However that results in NullPointerException
as sut
is not injected yet. 但是,由于尚未注入
sut
,因此会导致NullPointerException
。
@Before
public void recordExpectationsForPostConstruct()
{
new NonStrictExpectations(sut) {{ invoke(sut, "init"); }};
}
You can try manually initializing your class to be tested without using @Tested. 您可以尝试手动初始化要测试的类,而无需使用@Tested。 And then, set mock dependencies via setter methods (or using mockit.Deencapsulation.setField() method).
然后,通过setter方法(或使用mockit.Deencapsulation.setField()方法)设置模拟依赖项。
You can try something similar to this; 您可以尝试类似的操作;
//Define your class under test without any annotation
private MyServiceImpl serviceToBeTested;
//Create mock dependencies here using @Mocked like below
@Mocked Dependency mockInstance;
@Before
public void setup() {
//Initialize your class under test here (or you can do it while declaring it also).
serviceToBeTested = new MyServiceImpl();
//Set dependencies via setter (or using mockit.Deencapsulation.setField() method)
serviceToBeTested.setMyDependency(mockInstance);
//Optionally add your expectations on mock instances which are common for all tests
new Expectations() {{
mockInstance.getName(); result = "Test Name";
...
}};
}
@Test
public void testMyMethod(@Mocked AnotherDependency anotherMock) {
//Add your expectations on mock instances specifics to this test method.
new Expectations() {{
mockInstance.getStatus(); result = "OK";
anotherMock.longWork(); result = true;
...
}};
//Set dependencies via setter or using mockit.Deencapsulation.setField() method
Deencapsulation.setField(serviceToBeTested, "myAnotherDep", anotherMock);
//Invoke the desired method to be tested
serviceToBeTested.myMethod();
//Do the verifications & assertions
new Verifications() {{
....
....
}};
}
Perhaps you could delegate the longWork method to a different class and mock this one. 也许您可以将longWork方法委托给另一个类并模拟该类。 Difficulties while writing tests is often a sign of design flaws
编写测试时遇到困难通常是设计缺陷的标志
