Re: [xwiki-devs] Status on Docker + CI + Clover - Outstanding tasks

For example: In Clover build logs: " [INFO] Tests run: 5, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.011 s - in IdGeneratorTest [INFO] Running TransformationContextTest “ In clover.xml report: https://gist.github.com/vmassol/c8d3103147ddde3610d0c06bf44e37e1 ie 2 tests failing in IdGeneratorTest: testGenerateUniqueIdWhenInvalidEmptyPrefix & testGenerateUniqueIdWhenInvalidNonAlphaPrefix 2) Several tests failing in the Clover build logs but not in the clover report. For example: In Clover build logs: “ [ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 139.958 s <<< FAILURE! - in org.xwiki.menu.test.ui.MenuIT [ERROR] org.xwiki.menu.test.ui.MenuIT Time elapsed: 139.958 s <<< ERROR! “ In clover.xml report: https://gist.github.com/vmassol/b5d3ba0120f08fa6e52e09157cad2a45 ie no failure at all… Thus it’s not possible to trust the clover.xml report… The only solution I can think of would be to compare either with the local Maven build logs or with the Jenkins test report logs. But that means we can’t go back in the past since we don’t have those logs for past clover reports. The good news is that when Clover says that tests failed, they actually didn't fail for a lot of them (However we would need to check if the coverage done by those tests is included but I think they are from what I see: IdGenerator.java has coveredelements="75” & elements=“84”. That could be from tests other than IdGeneratorTest though).

Future failures should be related to point 6) below.

Option 1: execute Browser outside of docker as option, Option 2: add more docker-based agents. For the moment, we might be able to run the docker tests on agent4. >> >> 4) Screenshot attachment on UI test failures to fix in pipeline job >> >> 5) Flicker recognition on tests to fix in pipeline job >> >> 6) Fix the ClosedChannelExcption/InterruptedException in our CI >> >> 7) Research running Jenkins agents in docker images and make our Docker test work (docker on docker).
