java - 模拟 protected 构造函数

Question

我想模拟具有 protected 构造函数 的super() 调用。

为此，我使用“PowerMockito.suppress”但它不起作用(代码调用 super 构造函数并抛出 runtimeException)。

如何模拟 super call()，使其什么都不做。

    public class FooClass {

        public void someMethod(){
            String arg1 = "arg1";
            Integer arg2 =  123;
            ExtendedClass extendedClass = new ExtendedClass(arg1, arg2);
        }
    }

    public class SuperClass {
         protected SuperClass(String arg1, Integer arg2) {throw new RuntimeException();}
    }

    public class ExtendedClass extends SuperClass{

        public ExtendedClass(String arg1, Integer arg2){
            super(arg1, arg2);
         }
    }

    @RunWith(PowerMockRunner.class)
    @PowerMockRunnerDelegate(MockitoJUnitRunner.class)
    @PowerMockIgnore({"javax.management.*", "org.apache.http.conn.ssl.*", "com.amazonaws.http.conn.ssl.*", "javax.net.ssl.*"})
    @PrepareForTest({SuperClass.class})
    public class TestClass extends TestCase{

        @InjectMocks
        FooClass fooClass = new FooClass();

        @Test
        public void test(){
            PowerMockito.suppress(PowerMockito.constructor(SuperClass.class, String.class, Integer.class));
            fooClass.someMethod();
        }
    }

Answer 1

您必须为测试准备 ExtendedClass 而不是 SuperClass。

改变

 @PrepareForTest({SuperClass.class})

 PowerMockito.suppress(PowerMockito.constructor(SuperClass.class, String.class, Integer.class));

到

 @PrepareForTest({ExtendedClass.class})

 PowerMockito.suppress(PowerMockito.constructor(ExtendedClass.class, String.class, Integer.class));
