shicong	a7d099d2a3	Enable screenshot comparison in external build ... This change actually enabled the screenshot comparison in the visual regression tests. We used Docker to provision Chrome and ChromeDriver to eliminate the discrepancy of environment between local development and Travis CI. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=237811918	2019-03-20 14:25:28 -04:00
shicong	756a3b41e1	Implement screenshot comparison ... This change added the implementation of screenshot comparison with ChromeWebDriver which will be used in the open-source code base. This change also set a default window size(1200x2000) for each screenshot test. This is to make the size of screenshot deterministic to help build the screenshot comparison tests. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=235539713	2019-03-05 14:13:13 -05:00
