             Summary: [Umbrella] Migrate junit tests from JUnit 3 to JUnit 4
                 Key: OOZIE-3475
                 URL: https://issues.apache.org/jira/browse/OOZIE-3475
             Project: Oozie
          Issue Type: Task
            Reporter: Andras Salamon


OOZIE-783 upgraded JUnit 3 to JUnit 4 years ago, but most of out unit tests still use JUnit 3 style.

The following counting is not perfect, but shows the approximate numbers:
{noformat}
$ find . -name "Test*.java" | wc -l
     491
$ find . -name "Test*.java" | xargs grep 'extends.*TestCase' -l | wc -l
     346
{noformat}
Although there are ways to [automagically|https://stackoverflow.com/q/264680/21348] convert the tests, I don't think we can skip the manual work.

I open this umbrella jira (similarly to OOZIE-3111) so at least we are aware of the problem.
