    Description

      Based on the consensus from the mailing list discussion[1][2], we have been starting working on the JUnit4 to JUnit5 migration. 

      This is the umbrella ticket which describes the big picture of the migration with following steps:

      • AssertJ integration and guideline
      • Test Framework upgrade from JUnit4 to JUnit5
      • JUnit5 migration guideline(document and reference migration)
      • Optimization for issues found while writing new test in JUint5
      • [Long-term]Module based graceful migration of old tests in JUnit4 to JUnit5

       

      All JUnit5 migration related tasks are welcome to be created under this umbrella.
