question: @ Override public String toString ( ) { StringBuilder output = new StringBuilder ( ) ; if ( mTestClass != null ) { output . append ( mTestClass ) ; output . append ( '#' ) ; } if ( mTestName != null ) { output . append ( mTestName ) ; } if ( output . length ( ) > 0 ) { return output . toString ( ) ; } return "unknown result" ; }
target:  Provides a more user readable string for TestResult, if possible
