gmock_cook_book: Document DoAll's return type requirement

Browse Source

The return value of the last action **must** match the return type of the mocked
method. In the example above, `action_n` could be `Return(true)`, or a lambda
that returns a `bool`, but not `SaveArg`, which returns `void`. Otherwise the
signature of `DoAll` would not match the signature expected by `WillOnce`, which
is the signature of the mocked method, and it wouldn't compile.
### Verifying Complex Arguments {#SaveArgVerify}
If you want to verify that a method is called with a particular argument but the
