&引用；无法转换名为[类名]的类。原因：javax.servlet.ServletContext“；在ANT脚本中运行测试时

在运行ANT测试任务之后，当我尝试运行特定的测试套件时，日志中会出现初始化错误。完整堆栈跟踪如下所示：

Failed to transform class with name [CLASS NAME]. Reason: javax.servlet.ServletContext

目标是当被测试的类尝试实例化problemClass时，它只会创建一个模拟对象而不是一个真实实例

classBeingTested扩展了堆栈交易中提到的类。i、 e.classBeingTested扩展了[类名]

我还监视classBeingTested的实现，这样另一个方法在被调用时不做任何事情，而不是被调用

我不确定是否存在某种干扰，在这种干扰下，既要为测试准备类，又要在其中插入模拟构造函数，以及对其进行监视都是不合适的

注意：我可以使用run/debug在IntelliJ中很好地运行测试。在这两种情况下，测试都完成并显示为通过。因此，只有当ANT构建发生时，它才会失败

@RunWith(PowerMockRunner.class)
@PrepareForTest({problemClass.class, classBeingTested.class})
