I signed it!

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for all the commit author(s) or Co-authors. If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.
In order to pass this check, please resolve this problem and have the pull request author add another comment and the bot will run again. If the bot doesn't comment, it means it doesn't think anything has changed.

CLAs look good, thanks!

Could you please explain why it's better to use the latest action rather than the order in which they were added?

[tocrafty]

Sometimes, we need to set up default mock behaviors before test suite. In a test case, we can set up new actions for interface if we want to simulate some erros. After this actions is exhausted, mock behavior will fall back to default setup. With old strategy, all actions must be add as planed and carefully, And they can not be changed after setup. This would be very inflexible.

If I'm understanding correctly, this is an attempt to add support for loose mocks in a way. Is that correct?

If so, I've been pointing people towards #246 for a discussion there.

[tocrafty]

Yeah, you are right. I have read read #238 and #246 , and this PR should be redirected to #238 as an mock options for backward compatibility. I will close this one.
