Hmm, you could use a bool + the type, |bool has_received_event_|, then return
nullptr if it's false, or the address of the |last_event_type_| otherwise, and
just inline the pointer deref in the EXPECT_EQ. Crashing is as good as a failure
anyway.

e.g.,

SelectionEventType* GetAndResetLastEventType() {
  if (!has_received_event_)
    return nullptr;
  has_received_event_ = false;
  return &last_event_type_;
}

Or use different queries:

bool HasReceivedEvent() const {...}
SelectionEventType GetAndResetLastEventType()  {
  ASSERT_TRUE(HasReceivedEvent());
  has_received_event_ = false; ...
}

And use the former when you don't expect there to be a new event.

[mohsen, 2015/02/18 23:35:22]

I ended up adding a total count for events to be able to make sure no extra
event is happening, without checking all other events. This is similar to your
2nd suggestion (HasReceivedEvent + GetAndResetLastEventType). Does it look
reasonable to you?

This is a lot of boilerplate for every check.

What if we instead do |GetAndResetLastEventType()|, and have it return either a
(potentially empty) scoped_ptr, or a pointer to the received type (or nullptr if
no event has been received since the last reset).

I think there are only 2 or 3 places currently where the result should be null.

[mohsen, 2015/02/18 21:53:36]

There are some location where we test more than last event (e.g. line 365).
Also, using scoped_ptr would still be almost the same amount of code for each
test. Something like:

scoped_ptr<SelectionEventType> last_event = GetAndResetLastEventType();
ASSERT_NE(nullptr, last_event);
EXPECT_EQ(INSERTION_SHOWN, *last_event);

Do you have something cleaner in mind?
