shicong e382299212 Resolve carry-over state issue in TestServerRule ... The TestServerRule object is shared between retries in the same test, so the testServer object constructed in TestServerRule's constructor will be shared as well. This should be the reason why the test retry carries over some state. (The log in the test proves that the testServer object is shared because it listens to the same port in all retries, which should not happen if its constructor is invoked every time. You can find multiple "TestServerRule is listening on: []in this test [] So, this CL delayed the construction to rule.before() method which is invoked before every retry.(You can see each retry has a test server listening to different port and the error is "It differed by <16> pixels." for all attempts instead of not clickable button [] ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=246904446		2019-05-13 12:29:53 -04:00
