Plan to decouple with UnitTest?

Other than UnitTest, TestNG is very popular these days.

Any plan to support both?

Looks like it's tightly coupled with UnitTest in some place:

https://github.com/holdenk/spark-testing-base/blob/master/src/main/1.3/java/com/holdenkarau/spark/testing/SharedJavaSparkContext.java#L60

Start by reading src/main/1.3/java/com/holdenkarau/spark/testing/SharedJavaSparkContext.java around line 60, where the issue reports tight coupling with UnitTest. Investigate how the testing base classes depend on UnitTest and what supporting TestNG would require; done means defining a viable approach that supports both frameworks.
