Hi all, In SPARK-44170 (apache/spark#43074 [1]), I’m trying to migrate the Junit test framework used in Spark 4.0 from Junit4 to Junit5.
Although this involves a fair amount of code modifications, given that Junit 4 is still developed based on Java 6 source code and it hasn't released a new version for over two years (the Junit 4.13.2 that Spark is currently using was released on February 14, 2021.), I personally believe it's worth it. Feel free to comment if you have any concerns. [1] https://github.com/apache/spark/pull/43074 Thanks, Jie Yang
