This report therefore seeks to cover both the design of the required test software and the design of the user interface - the interaction between the tester and validation software - for the checking process. Section 2 considers the aims and difficulties of visual testing. Further design features and the scope of the tests are addressed in section 3. A key element of the testing process is the document associated with each test, and a specification of this is given in section 4. Section 5 moves on to the user inerface and describes the underlying model for the test process. The user interface process has three tasks: (i) to handle interaction with the tester; (ii) to access the test documents, so as to present information to the tester; (iii) to pass information to the automatic report generator, concerning the tester's assessment of we ther a t est has been passed or failed. Section 6 defines the user interface for these three tasks and section 7 contains examples of various features.enCGITSI006report
