Is there a kind of action in the EXPECT_CALL of Gmock?












0















The SUT is calling an external library for which an EXPECT_CALL is defined.
I want to only do something when the function is called for the first time and ignore doing anything the other time (but check that it's called twice); and vice versa.. i.e. do nothing the first time it is called and something the second time it is called.



// Code for the Expect Call  
EXPECT_CALL(*mock_ptr, some-function(_,_)) .Times(2) .WillOnce(action1)
.WillOnce(do-nothing);

// SUT call
ASSERT_NO_THROW(sut_function(arg1, arg2));


Ignoring the second (do-nothing) WillOnce, I am getting a Gmock warning like:




GMOCK WARNING: test_blah-blah.cpp:321: Too few actions specified in
EXPECT_CALL(*mock_ptr, some-function(,))... Expected to be called
twice, but has only 1 WillOnce(). GMOCK WARNING:
test_blah-blah.cpp:321: Actions ran out in EXPECT_CALL(*mock_ptr,
some-function(,))... Called 2 times, but only 1 WillOnce() is
specified - returning directly.




What action do I give in the do-nothing part to not get this warning?
some-function is a void returning function.



Thanks!

          Adding Return() for the second(or the first) .WillOnce solved the problem. Referred to the cheatsheet in github to find the matching action.
