[GitHub] [openwhisk-wskdebug] alexkli opened a new issue #84: flaky agentmgr.test.js tests in Travis
alexkli opened a new issue #84:
URL: https://github.com/apache/openwhisk-wskdebug/issues/84
The tests in agentmgr.test.js have become very flaky (Dec 2020 after not many changes and Travis job runs since the 1.3.0 release in July). Possibly due to newer [faster hardware in Travis](https://blog.travis-ci.com/2020-09-11-arm-on-aws) or docker related changes. It can resolve on a re-run, but it takes a few times.
A similar flaky test was fixed in https://github.com/apache/openwhisk-wskdebug/pull/82.
Example failed job: https://travis-ci.com/github/apache/openwhisk-wskdebug/jobs/464430797
Test failures:
```
1) agentmgr
should use non-concurrent agent if openwhisk does not support concurrency:
Error: Timeout of 30000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/home/travis/build/apache/openwhisk-wskdebug/test/agentmgr.test.js)
2) agentmgr
should handle if the agent was left around from a previous run:
Error: (HTTP code 500) server error - driver failed programming external connectivity on endpoint wskdebug-myaction-1608750742209 (70bb0576af18dc960ee9ed18f704100d9baffe0f994f783f49330e4bd99a36c7): Bind for 0.0.0.0:46747 failed: port is already allocated

3) agentmgr
should remove backup action if --cleanup is set:
Error: Unexpected error while polling agent for activation.
at AgentMgr.waitForActivations (src/agentmgr.js:65:181)
at process._tickCallback (internal/process/next_tick.js:68:7)
```
It seems the `should use non-concurrent agent if openwhisk does not support concurrency` fails to start or shutdown the docker container and times out waiting for that. This can then have detrimental effect on the subsequent tests that fail too, it seems.

With verbose logging it became clear the problem is that wskdebug inside the tests times out downloading the Runtime docker image `adobeapiplatform/adobe-action-nodejs-v10:3.0.21`.
See https://travis-ci.com/github/apache/openwhisk-wskdebug/jobs/464466116
This explains the flakyness as this depends on whether the image was cached in the Travis environment and on the bandwidth between Travis and docker hub.
Fix: https://github.com/apache/openwhisk-wskdebug/pull/82/commits/ecdfaba7b697cf667837b72c2641c97952b44806
