UtilsVerifier

UtilsVerifier is a pure Java library that can be used in Junit tests to verify that Utility class is properly defined.

By default verification includes:

class having only one private constructor
class being final
class having no instance fields
class having no instance methods
class having no static mutable fields

Usage

    UtilsVerifier.forClass(ClassToTest.class).verify();

It's possible to disable one or more of the default verification checks by using set of "suppress" methods.

    UtilsVerifier.forClass(ClassToTest.class)
                 .suppressFinalClassCheck(true)
                 .suppressOnlyOneConstructorCheck(true)
                 .verify();

If the tested class constructor should throw an exception when used it's possible to specify the type of the exception.

    UtilsVerifier.forClass(ClassToTest.class)
                 .withConstructorThrowing(DesiredException.class)
                 .verify();
