To use the degenerate test helper:

References/Links

For repetitive testing of degenerate use of methods with null and empty values, a class DegenerateUseMethodTestHelper is provided, which includes two static methods

• DegenerateUseMethodTestHelper(Object, Method, Parameters, ExpectedFailures)
• DegenerateUseMethodTestHelper(Object, Method, Parameters)

where:

• Object:  The service client undergoing testing
• Method:  The method of the service client to be tested
• Parameters:  An object array of values that that produce successful invocation of the method
• ExpectedFailures:  An ExpectedFailure array specifying the degenerate behavior for each parameter.  
  • EXCEPTION,
  • SKIP,
  • NONE,
  • LONG_INVALID_NO_RESULTS_NULL_EXCEPTION,
  • STRING_EMPTY_EXCEPTION_NULL_EXCEPTION,
  • STRING_EMPTY_EXCEPTION_NULL_NO_RESULTS,
  • STRING_EMPTY_EXCEPTION_NULL_SUCCESS,
  • STRING_EMPTY_NO_RESULTS_NULL_EXCEPTION,
  • STRING_EMPTY_NO_RESULTS_NULL_NO_RESULTS,
  • STRING_EMPTY_NO_RESULTS_NULL_SUCCESS,
  • STRING_EMPTY_SUCCESS_NULL_EXCEPTION,
  • STRING_EMPTY_SUCCESS_NULL_NO_RESULTS,
  • STRING_EMPTY_SUCCESS_NULL_SUCCESS,
  • NO_RESULTS,

Example:

SecurityClientRest service = new SecurityClientRest(ConfigUtility.getConfigProperties());
 
// use reflection to get the desired method
Method method =
        service.getClass().getMethod(
			"authenticate", 								// method name and parameters
			new Class<?>[] {String.class, String.class});	// i.e. SecurityClientRest.authenticate(String username, String password)
 
// specify the valid parameters
Object[] parameters = new Object[] {
        new String("name"), new String("password")			// valid parameters that when passed to method produce successful outcome (e.g. authentication)
    };
 
// call the helper
DegenerateUseMethodTestHelper.testDegenerateArguments(service, method,
        parameters);
