Question

我需要为MyClass类编写测试。

public class MyClass {
        public Result<Data> get() {
            return Request
                .buildRequest(session, Data.class, new DefaultErrorHandler())
                .executeAndConvert();
        }
    }

我的请求类

    public class Request<Type> implements RequestBuilder<Type> {
        public static <T> Request<T> buildRequest(String session, Class<T> responseClass) {
            return buildRequest(session, responseClass, null);
        }

        public static <T> Request<T> buildRequest(String session, Class<T> responseClass, ErrorHandler errorHandler) {
            Request<T> request = new Request<T>(session, responseClass);
            // some logic
            return request;
        }

        @Override
        public Result<Type> executeAndConvert() {
            Invocation.Builder req = buildRequest();
            return executeRequest(req);
        }
        // some other code
}

这是我的测试代码

PowerMockito.mockStatic(Request.class);
PowerMockito.when(Request.buildRequest(sessionMock, Data.class)).thenReturn(requestMock);
myClass.get(); // which is return a Request object

我想禁用Request构造函数调用，因为我在内部触发时会获得NPE。实际上我不需要在构造函数或方法链中调用所有方法。我只需要返回一个模拟的结果。

PowerMockito.when(Request.buildRequest(sessionMock, Data.class)).thenReturn(requestMock);

与您呼叫的呼叫不匹配：

Request.buildRequest(session, Data.class, new DefaultErrorHandler())

您还应该为ErrorHandler添加匹配器。如果没有设置任何内容，则会返回null，正如您所说。

如何在Mockito / PowerMock中禁用构造函数执行？
