googleAuthorizationCodeGrant

googleAuthorizationCodeGrant

我正在尝试模拟这样的类(感谢Google的代码设计,该代码在测试环境中很难使用):

GoogleAuthorizationCodeGrant googleAuthorizationCodeGrant = EasyMock.createMock(GoogleAuthorizationCodeGrant.class);


然后,我将建立一个模拟方法调用,如下所示:

AccessTokenResponse accessTokenResponse = new AccessTokenResponse();
EasyMock.expect(googleAuthorizationCodeGrant.execute()).andReturn(accessTokenResponse);


但它会产生异常,因为在googleAuthorizationCodeGrant.execute()期间,它会尝试运行GoogleAuthorizationCodeGrant.execute()中的实际代码。我在这里想念什么吗?我希望cglib代理可以包装此类并重写它的方法而不做任何事情,因为我不希望它们在模拟时实现。当我定义各种方法调用的行为时,就不需要保留任何业务逻辑。

编辑

注意-我认为这里有些混乱。抛出异常:

EasyMock.expect(googleAuthorizationCodeGrant.execute()).andReturn(accessTokenResponse)


当我将模拟置于重播模式时,不是这样,因为我从未真正到达该代码。引发该异常的原因是因为GoogleAuthorizationCodeGrant的成员为null,并且在.execute()上对其调用了一个方法。如果我使用新的运算符实例化了GoogleAuthorizationCodeGrant,则该成员将不会为null。但是我不明白为什么EasyMock会在类上这样工作,因为我希望它创建一个代理来包装实现,而不执行任何操作。

这是堆栈跟踪:

最佳答案

我不确定您是否重播了该模拟实例。如果您已经这样做并且仍然遇到异常,请放入堆栈跟踪。
