Object Oriented Help Wizard ● ● ● James Sheets, CIS - SE Mike Kinnell, ECE - CE Brian Rodriguez, CIS - SE Introduction ● ● ● ● The project aims to: Create a web-based program to aid in the construction of layered, object oriented software. Break down a project into layers, with reusable components exposed through an interface to higher layered components. Include help topics and explanations to better aid users in constructing a layered application. Project Requirements ● Take user input and store it ● Display a visual breakdown of the layered system ● Help system which can easily be navigated, to allow the user to better use the program Major Constraints ● Simple program; limited in depth. ● Requires web server with PHP Data Design ● ● A Component represents a basic functionality that should be implemented in a layer. A Layer stores a number of Components, the layer's name, and the layers level. Data Design ● ● Data structure stored in a SESSION variable. Help Data class holds a static listing of all help topics and documentation. Architecture Diagram Input field component ● Each page passes input information into program. Help link component ● Subject links to help data. Next button component ● HTML button; step through program. Finish button component ● HTML button; show display diagram. Back button component ● Web browser button; move back in program. Restrictions, limitations, constraints ● ● ● Requires a web server that supports PHP and Pear’s HTML/Quickform extensions for PHP Requires a client computer with a web browser that supports the World Wide Web Consortium (W3C) HTML 3.0 standard and may not operate properly other browsers. Does not support WAP or mobile web browser applications. User Interface ● Font Sizes: We use a relatively large font size to make it easy for users to read the screen without distractingly large. User Interface ● Separation of Areas: Simple, easy-to-use design. User Interface ● Color Scheme: Easy on eyes. Errors stand out. Unit Testing ● ● ● Black box testing Each input page will have test data entered This will prove that each of the output generation modules are fully functional and will also test for the appropriate actions of the hyperlinks and input modules if the input data is incorrect or missing Integration Testing ● ● ● ● Top down integration testing strategy Will involve the incorporation of the input and output modules into the CGI handler of the host web server The modules should generate the proper HTML pages as predicted without error. We will also be testing each page and module for correct handling of the browsers built-in caching functions and what happens if the user hits the browsers back or forward buttons. Validation Testing ● ● ● ● Every function will be tested to demonstrate conformity with the requirements The Next and Help hyperlinks buttons will be tested to ensure that the resulting output page has the correct information The system will be tested with different browsers and should handle the browsers back and forward functions properly The final layered system model displayed should be accurate and complete. High-order Testing ● ● ● Stress testing will be done using a macro program that will rapidly and repeatedly navigate though the user interface. The website should generate the appropriate output without errors or unpredicted results. Performance testing will be done on modules to ensure that no significant bottlenecks are present and that the modules can handle rapid calls without degradation to system performance. Beta test version will be generated to test the entire system and ensure that the system performs as expected with various users and user inputs. Demo Time Questions?
