Thread: Test noExceptions

Hi,

I want to test that a function has no any exceptions.

In C++ and Google Test Framework (GTest) it will look like this:

ASSERT_NO_THROW({
                    actual = divide(a, b);
                });

How will it look in Java? I am new in jUnit. I love you! Thank you!

Thanks!

Is this normal?

    /**
     * Test of checkPersonFields method, of class FreeFunctions.
     */
    @Test
    public void testNormalTest() throws Exception
    {
        String nickName = "8Oberver8";
        String firstName = "Ivan";
        String lastName = "Enzhaev";
        String phoneNumber = "+79172122959";
        String email = "8observer8@gmail.com";
 
        Person person = new Person( nickName, firstName, lastName,
                phoneNumber, email );
 
        FreeFunctions instance = new FreeFunctions();
 
        try {
            instance.checkPersonFields( person );
        } catch ( Exception e ) {
            fail("Should not have thrown any exception");
        }
    }

I see that it is normal

Such I test methods with exceptions:

    @Rule
    public ExpectedException exception = ExpectedException.none();
 
    // ...
 
    /**
     * Test of checkPersonFields method, of class FreeFunctions.
     */
    @Test
    public void testErrorEmail03() throws Exception
    {
        String nickName = "8Oberver8";
        String firstName = "Ivan";
        String lastName = "Enzhaev";
        String phoneNumber = "+79172122959";
        String email = "@gmail.com";
        Person person = new Person( nickName, firstName, lastName,
                phoneNumber, email );
 
        FreeFunctions instance = new FreeFunctions();
 
        exception.expect( ErrorEmail.class );
        instance.checkPersonFields( person );
    }
 
    // ...
