- 3. Team Roles • Artur Musin • Site base • Ad handling • Database development • Sean Martinez • User handling • Message handling • Backend functions 3
- 4. “Zygura” Features • Publish Ads • View Ads as a Listing • View Ads on the Google Map • Quick access to Ad details and images • Flexible search by various criteria • Handy user-to-user communication 4
- 5. “Zygura” Advantages • Clean & User friendly interface • Browsing and searching without page reloads • Quick access to an Ad content and its images • Quick and simple communication mechanism • Unobtrusive client-side forms input validation • Decoupled code base for facilitating Unit Testing 5
- 6. Problem • Users have to browse the full ad list • Ads contain too much information • Time is wasted skimming through irrelevant ads 6
- 7. Design Patterns used 7 • MVC (Model-View-Controller) • Unit of Work (Repository) • Service Locator (Inversion of Control container) • Composition Root (Modules Dependency Inversion) • Dependency Injection (Class Constructor Injection) • Factory pattern • Iterator pattern • Observer pattern • Decorator pattern • Strategy pattern • Singleton pattern • Façade pattern
- 8. Design Principles used (S.O.L.I.D.) 8 • Single Responsibility principle (class should have only one responsibility) • Open-Closed principle (class should be opened for extension and closed to modification) • Liskov Substitution principle (subtypes should be substitutable for its base types) • Interface Segregation principle (interfaces should not be “fat”) • Dependency Inversion principle (depend upon abstraction, not upon concretion)

Integration Testing Test Data Expected Results Actual Results Test Status (Pass, Fail, Not Tested) Tested By Comments Corrective Action What data will be used What should the module do What actually occurred Outcome Who did the test Any comments What was done to fix the problem Textual information along with images All manually added Ads must be displayed on the webpage after clicking Search button List of ads was returned to user Pass Artur Musin There were no problems Textual information along with images All manually added Ads must be displayed on the webpage after clicking Search button Array of ads was returned to the Google map Pass Artur Musin There were no problems Simple text and images Ad record should be added to the database A new record appeared in the dbo.Ads table Pass Artur Musin There were no problems Already precreated ads in the database A record should disappear from Database A record was removed from dbo.Ads table Pass Artur Musin There were no problems Already precreated ads in the database A record should change its state A record was successfully updated Pass Artur Musin There were no problems 31

- 33. Lessons Learned • Decoupled modules make code editing and updates cleaner • Interfaces make classes more flexible • The biggest challenge of the MVC code structure is transferring data from one module to another 33
