我有一个类A,它调用抽象类B的静态方法,抛出一些异常。我想测试这个例外。我正在使用junit 4.1,mockito 1.9.5和powermock 1.6.6。课程是:
abstract class B {
public static void meth(String str) throws SomeException1, SomeException2,SomeException3 {
//some code
}
}
class A{
public void method() throws SomeException1, SomeException2,SomeException3 {
B.meth1("abc");
}
}
我想测试这些异常,这是我的测试类
@RunWith(MockitoJUnitRunner.class)
@PrepareForTest(B.class)
class Test throws Throwable {
public void testException(){
PowerMockito.mockStatic(B.class); //Line 6
when(B.meth(Mockito.any(String.class))).thenThrow(new SomeException1(), new SomeException2(), new SomeException3() );
A obj=new A();
obj.method();
}
}
}
执行此测试用例时,我得到一个异常
org.powermock.api.mockito.ClassNotPreparedException:
The class B not prepared for test.
To prepare this class, add class to the '@PrepareForTest' annotation.
In case if you don't use this annotation, add the annotation on class or method level.

关于我为什么会这样做的任何建议?
答案 0 :(得分:2)
您需要:@RunWith(PowerMockRunner.class)
答案 1 :(得分:1)
您可以使用powermock来模拟静态方法。
代码示例
@RunWith(PowerMockRunner.class)
public class TestStaticMethodExample {
private SomeClass c = new SomeClass ("g", "123");
@PrepareForTest({ SomeStatic.class })
@Test
public void stubStaticMethod() {
PowerMockito.mockStatic(SomeStatic.class);
PowerMockito.when(SomeStatic.getSummary()).thenReturn(new
SomeClass("t", 9999));
}
}
