why can I not just pass an int or bool directly into the OCMock's "andReturnValue" argument?

I was trying to do:

[[[mockQuestion stub] andReturnValue:YES] shouldNegate];
[[[mockQuestion stub] andReturnValue:123] randomNumberWithLimit];

But that gave me this warning/error "incompatible integer pointer conversion sending 'BOOL' (aka 'signed char') to parameter of type 'NSValue *'"

The only way I could figure out to get around it was to do:

BOOL boolValue = YES;
int num = 123;

[[[mockQuestion stub] andReturnValue:OCMOCK_VALUE(boolValue)] shouldNegate];
[[[mockQuestion stub] andReturnValue:OCMOCK_VALUE(num)] randomNumberWithLimit];

But that makes my test code seem so overly verbose.. Is there a way to do this all inline without having to set variables?

The parameter is supposed to be an object pointer. In this case it should point to an object of the NSValue class.

You can use a literal style that looks like (type){value}. This is commonly used to create struct literals but works for basic datatypes too. The important aspect here is that this type of literal creates a temporary that can be addressed. This means you can write your code like

[[[mockQuestion stub] andReturnValue:OCMOCK_VALUE((BOOL){YES})] shouldNegate];
[[[mockQuestion stub] andReturnValue:OCMOCK_VALUE((int){123})] randomNumberWithLimit];
