class AgeTest {

    @DisplayName("Valid ages")
    @ParameterizedTest(name = "{0} is a valid age for the requirement 18 to 30")
    @ValueSource(ints = {18, 19, 29, 30})
    void validAges(int age) {
        Assertions.assertThat(isAgeValid(age)).isTrue();
    }


    @DisplayName("Invalid ages")
    @ParameterizedTest(name = "{0} is an invalid age for the requirement between 18 to 30")
    @ValueSource(ints = {17, 31})
    void invalidAges(int age) {
        Assertions.assertThat(isAgeValid(age)).isFalse();
    }    
}
