Junit Vs Testng

• Comparing TestNG Vs JUnit, TestNG annotations are easier to use and understand than JUnit.
• "TestNG allows us to create parallel tests, whereas JUnit does not support running parallel tests."
  • but https://www.baeldung.com/junit-5-parallel-tests
• In TestNG, Test cases can be grouped together, while in JUnit, Grouping tests together is not possible.
• "the declaration of @BeforeClass (Private) and @AfterClass (Private) method has to be static in JUnit. By comparison, TestNG method declaration doesn’t have these constraints."
• junit5's "@MethodSource – passes external methods generating streams:" seems awesome. could it take parameter streams from the network?
