当我在运行ANT测试任务后尝试运行特定的测试套件时，在日志中出现初始化错误。完整堆栈跟踪如下：

当我将以下内容添加到测试套件的开头时，问题就出现了：
@RunWith(PowerMockRunner.class)
@PrepareForTest({problemClass.class, classBeingTested.class})
目标是当被测试的类试图实例化problemClass时，它只会创建一个模拟对象而不是实例。
classBeingTested扩展了堆栈交易中提到的类。即classBeingTested扩展[CLASS NAME]。
我也在监视classBeingTested的实现，因此在调用而不是被调用时，另一个方法什么都不做。
我不确定是否存在某种干扰，在这种情况下，为测试准备课程并在其中插入以及间谍的模拟构造函数是不正确的？ / p>
注意：我可以使用run / debug在IntelliJ中运行测试。在这两种情况下，测试都完成并显示为通过。所以只有在ANT构建发生时它才会失败。
