我有一个类似下面的代码:
I have a code somewhat like this below:
Class A {
public boolean myMethod(someargs) {
MyQueryClass query = new MyQueryClass();
Long id = query.getNextId();
// some more code
}
}
Class MyQueryClass {
....
public Long getNextId() {
//lot of DB code, execute some DB query
return id;
}
}
现在我正在为 A.myMethod(someargs)
编写测试.我想跳过真正的方法 query.getNextId()
而是返回一个存根值.基本上,我想模拟 MyQueryClass
.
Now I'am writing a test for A.myMethod(someargs)
. I want to skip the real method query.getNextId()
and instead return a stub value. Basically, I want to mock MyQueryClass
.
所以在我的测试用例中,我使用了:
So in my test case, I have used:
MyQueryClass query = PowerMockito.mock(MyQueryClass.class);
PowerMockito.whenNew(MyQueryClass.class).withNoArguments().thenReturn(query);
when(query.getNextId()).thenReturn(1000000L);
boolean b = A.getInstance().myMethod(args);
//asserts
我在测试类的开头使用了 @RunWith(PowerMockRunner.class)
和 @PrepareForTest({MyQueryClass.class})
.
I used @RunWith(PowerMockRunner.class)
and @PrepareForTest({MyQueryClass.class})
in the beginning of my test class.
但是我调试测试的时候,还是调用了MyQueryClass
类的真实方法getNextId()
.
But when I debug the test, it is still calling the real method getNextId()
of the MyQueryClass
class.
我在这里缺少什么?任何人都可以提供帮助,因为我是 Mockito 和 PowerMockito 的新手.
What am I missing here? Can anyone help as I am new to Mockito and PowerMockito.
需要将调用构造函数的类放到@PrepareForTest
注解中,而不是正在构造的类 - 请参阅 模拟新对象的构造.
You need to put the class where the constructor is called into the @PrepareForTest
annotation instead of the class which is being constructed - see Mock construction of new objects.
在你的情况下:
@PrepareForTest(MyQueryClass.class)
@PrepareForTest(A.class)
更笼统的:
@PrepareForTest(NewInstanceClass.class)
@PrepareForTest(ClassThatCreatesTheNewInstance.class)
这篇关于使用 PowerMockito.whenNew() 不会被嘲笑,而是调用原始方法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!
