anyString（）或anyInt（）或anyLong（）方法不能正确地存根方法

Question

当Iam在Mockito中使用anyString（）或anyInt（）或anyLong（）方法时，stubbing不起作用。如果我使用anyObject()，它工作得很好。例如，如果我们有使用此签名的方法：

List<Service> getAllPurchasedServices(
      boolean isAgreement, String billingAccountId) throws ApiException

嘲笑：

when(serviceRestAPI.getAllPurchasedServices(anyBoolean(), anyString())).thenReturn(services);

当在测试的方法内部调用此模拟时，它将抛出NullPointerException。但是如果我们为anyObject（）更改它，一切都很好。有人知道为什么anyString（）会导致NullPointerException吗？

当使用anyString（）或anyLong（）时，mockito将认为null值不符合String或Long；这样你的存根就不能用了。您可以使用any()，也可以确保参数不为空。
