@Test
public void testAssert()
{
String s1="Pass", s2="Pass", s3=null;
byte a1[]={1, 2, 3};
byte a2[]={1, 2, 3};
assertEquals(s1, s2); //assertion to compare two String are equal
assertNull(s3); //assertion to check null
assertArrayEquals(a1, a2); //assertion to check equality of two byte array
System.out.println("Tests passed");
}
}

OUTPUT:
