JUnit Test can be converted to TestNG

Reports any JUnit-based test class that can be converted into TestNG based unit test.

Example:

import org.junit.Test;
import static org.junit.Assert.*;

public class ExampleTest {
  @Test
  public void testExample(){
    assertEquals(2 + 2, 4);
  }
}

After the quick-fix is applied:

import org.testng.Assert;
import org.testng.annotations.Test;

public class ExampleTest {
  @Test
  public void testExample(){
    Assert.assertEquals(4, 2 + 2);
  }
}
