Groovy adds the toBoolean() method to the String class. If the value of the string is true, 1 or y the result is true, otherwise it is false.
assert "y".toBoolean() assert 'TRUE'.toBoolean() assert ' trUe '.toBoolean() assert " y".toBoolean() assert "1".toBoolean() assert ! 'other'.toBoolean() assert ! '0'.toBoolean() assert ! 'no'.toBoolean() assert ! ' FalSe'.toBoolean()
