why don't you need to run the RunLoop here? If that's a mistake, then the test
shouldn't be passing, right?

It looks like you want to reset helper.word() before reusing the helper (or just
make a new helper). Maybe WaitForString* should reset word(), to prevent this
type of error from happening?

[EhsanK, 2016/09/01 21:58:37]

I should have used the loop. Fails without it since range (0, 5) is the word
"This " and what we get from GetStrignAtPoint is "This". So I fixed the range to
be 0 - 4 and now the test is happy (and correct).

With the message loop, helper.word() and helper.point() will get reset to the
new value after the loop stops (if it doesn't test times out). So I don't think
I should reset them now.

This should be in an anonymous namespace?

Actually I do not need this method anymore. Sorry for leaving it there. Removed.

[EhsanK, 2016/09/01 21:58:37]

Done. When I get a chance I will take a look at 'git cl format' code for
wrapping comments. It does not do a good job when you extend only one line of
comment to over 80 and then call it.

can you add an expectation that verifies the contents of "word"? ditto on the
next test.

Done. Thanks! (the word to be verified is "This").
