Can we override @Test annotated methods of Unit Test class

[former_member6861]

For example there is a test class DefaultWarehousingAsnFacadeTest in warehousingfacade extension hybris version 6.4. In this class test method shoulteAsn() is always failing because while setting up asnData object (which is a private member of the class) hybris is mocking releaseDate with some old date (2017-12-19). But in facade there is a validation on releaseDate that it should be a future date.

So ant unittests is generating fail report. To solve this issue I am trying to override the behavior of this class. I tried to override @Before method but asnData is a private member of the class. now I am trying to override @Test method, but the problem is super method is also getting called while ant unittests. So my whole purpose of overriding this class is waste.

Please suggest any solution.
