Misplaced argument matcher detected here. You cannot use argument matchers outside of verification or stubbing in Mockito

Question

Out of the following two test cases in BundleProcessorTest.java, i am getting below exception, although, my first test case passes successfully.

Answer 1

You are using mockito anyString() while calling the test method, it should be used only for verifying a mock object to ensure a certain method is called with any string parameter inside the test, but not to invoke the test itself. For your test use empty string "" instead to anyString().
