-------------------------------------
Summary: Rerun Failing Tests through Maven surefire
Key: OOZIE-3148
URL: https://issues.apache.org/jira/browse/OOZIE-3148
Project: Oozie
Issue Type: Improvement
Components: tests
Affects Versions: trunk
Reporter: Attila Sasvari
Priority: Minor
Fix For: 5.0.0b1
OOZIE-2817 introduced rerunning of failing test cases in pre-commit builds
(changed {{bin/test-patch-20-tests}} Bash script).
It is no longer necessary as OOZIE-3106 upgraded surefire-plugin to 2.20.1 and
since of 2.19.1 version of the maven surefire plugin it is allowed rerunning
failing tests via {{-Dsurefire.rerunFailingTestsCount=2}} (see
http://maven.apache.org/surefire/maven-surefire-plugin/examples/rerun-failing-tests.html).
For example, a test passed in its second run will output on the screen:
{code}
Run 1: ...
Run 2: PASS
Then this test will be counted as a flaky test. The build will be successful,
but in the end of the summary of all tests run, the number of flaky tests will
be output on the screen, for example:
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Flakes: 1
{code}
We could introduce this mechanism and update {{bin/test-patch-20-tests}}.
