Mockito.doReturn(true).when(a)
 .isTest(Const.A,
 Const.B);

In the above code cacheGet method returns a boolean value.(true/false)
I want to use a wildcard for that instead true or false.

Mockito.doReturn(?).when(a)
 .isTest(Const.A,
 Const.B);

I want to use the wildcard in place where '?' is.

  I don't understand your question. Either you want to return true when that method gets called, or you want to return false. What would you expect Mockito to do, as a result of you specifying the wildcard?

  I'm new to Mocking, but I don't get it. What do you expect to do with this? You're telling Mockito to return...what? --- ha! @DawoodibnKareem had the same idea, so I guess even newbie Mockito guy me kinda gets it. Coolio.

Your code

Mockito.doReturn(true).when(cacheAdaptorCore)
 .cacheGet(OMSConst.DEFAULT_TENANCY_CODE,
 OMSConst.APP_PARAM_DECIMAL_FORMATTER, 
CACHE_NAMES.SYS_PARAMS_CACHE_CORE);

tells Mockito, "Hey Mockito, if, during the following test, somehow the method cacheAdapterCore.cacheGet() is called with the parameters OMSConst..., do not really call the method, but instead make the code believe that the method returns true."

Now try the same sentence with "... make the code believe that the method returns ???"

See, it makes no sense.

If you want to do different tests and for some you want the method to return true, and for others you want it to return false, then you have to write separate test methods and within them, tell Mockito to return true resp. false.
