Java: How to verify that String has many characters

Question

Consider the test messageTest(see below)

  publicclassmessageTest { 
    @Test
    publicvoidtestMessageLength() {
    String message = "Test Message";

    }
}

Add Assert method to verify that text in message contains 12 characters.

Answer 1

You can assert it with actual length and expected length of the String. You need to import either junit Assert or testNg Assert, in order to use it

@Test
    publicvoidtestMessageLength() {
    String message = "Test Message";
    Assert.assertEquals(message.length(), 12);
    }

Answer 2

String.length()

If that is what you are looking for.
