cetsai opened a new pull request #11991: [MXNET-644] Automated flaky test detection
URL: https://github.com/apache/incubator-mxnet/pull/11991
 
 
   ## Description ##
   This PR adds the necessary components for an automated flaky tests detection measure, the design of which is detailed [on the wiki](https://cwiki.apache.org/confluence/display/MXNET/Automated+Flaky+Test+Detector).
   
   These components, diff collator, dependency analyzer, and flakiness checker are used by the check_flakiness script, which will be run in a Jenkins pipeline to automatically check PRs for flaky tests. Once active, the tool will mark PRs  that cause flaky tests so that they can be fixed before being merged with master.
