difference between junit and testng

JUnit  --> @Test, @BeforeClass, @AfterClass, @Before, @After, @Ignore
TestNG --> @Test, @BeforeTest, @BeforeClass, @BeforeSuite, @BeforeMethod, 
		   @AfterTest, @AfterClass, @AfterSuite, @AfterMethod
-Both are testing framework to help us running automation scripts.
-TestNG provide HTML report.
-TestNG has @DataProvider annotation same as Cucumber Scenario Outline for DDT
-Both We can do parallel testing, but in different way. In TestNG we use XML
runner. In JUnit we use Maven Surefire Plugins.
-TestNG support group test but JUNit doesn't support.
-TestNG and JUnit both of them have parameterized testing but TestNG 
parameterizedd test configuration is very easy to configure. There are two ways
to achieve it in TestNG;
@Parameters and TestNG xml file
