  • Hello, I am Brenda waters After being in relationship with Jeff for years, he broke up with me, I did everything possible to bring him back but all was in vain, I wanted him back so much because of the love I have for him, I begged him with everything, I made promises but he refused. I explained my problem to my friend and she suggested that I should rather contact a spell caster that could help me cast a spell to bring him back but I am the type that never believed in spell, I had no choice than to try it, I mailed the spell caster, and he told me there was no problem that everything will be okay before three days, that my ex will return to me before three days, he cast the spell and surprisingly in the second day, it was around 4pm. My ex called me, I was so surprised, I answered the call and all he said was that he was so sorry for everything that happened that he wanted me to return to him, that he loves me so much. I was so happy and went to him that was how we started living together happily again. Since then, I have made promise that anybody I know that have a relationship problem, I would be of help to such person by referring him or her to the only real and powerful spell caster who helped me with my own problem he used his Africa Black Power. His email: you can email him if you need his assistance in your relationship or any other Cases. 1) Love Spells 2) Lost Love Spells 3) Divorce Spells 4) Marriage Spells 5) Binding Spells 6) Breakup Spells 7) Banish a past Lover. 8.)

  10. 10. 10 Web App Testing Process - 1 • Content testing – tries to uncover content errors • Interface testing – exercises interaction mechanisms and validates aesthetic aspects of UI • Navigation testing – use-cases basis for design of test cases that exercise each usage scenarios against the navigation design (integration testing)
  11. 11. 11 Web App Testing Process - 2 • Component testing – exercises the WebApp content and functional units (integration testing) • Configuration testing – attempts to uncover errors traceable to a specific client or server environment – cross-reference table is useful
  12. 12. 12 Web App Testing Process - 3 • Performance testing to assess – WebApp response time and reliability under varying system loads – Which WebApp components are responsible for system degradation – How performance degradation impacts overall WebApp requirements • Security testing – tests designed to exploit WebApp or environment vulnerabilities
  13. 13. 13 Web Testing Task Set - 1 • Review stakeholder requirements • Establish priorities to ensure each user goal will be adequately tested • Define WebApp testing strategy by describing the types of tests that will be conducted
  14. 14. 14 Web Testing Task Set - 2 • Develop test plan – Define test schedule and assign testing responsibilities – Specify automated testing tools – Define acceptance criteria for each class of test – Specify defect tracking mechanisms – Define problem reporting mechanisms
  15. 15. 15 Web Testing Task Set - 3 • Perform unit tests – Review content for syntax and semantics errors – Review content for proper permissions – Test operation of interface mechanisms – Test each component for proper function
  16. 16. 16 Web Testing Task Set - 4 • Perform integration tests – Test interface semantics against use-cases – Conduct navigation tests • Perform configuration tests – Assess client-side compatibility – Assess server-side configurations • Conduct performance tests • Conduct security tests
  17. 17. 17 Content Testing Objectives • Uncover syntactic errors in all media – (e.g. typos) • Uncover semantic errors – (e.g. errors in completeness or accuracy) • Find errors in organization or structure of content presented to end-user
  18. 18. 18 Database Testing - 1 • The original query must be checked to uncover errors in translating the user’s request to SQL • Problems in communicating between the WebApp server and Database server need to be tested.
  19. 19. 19 Database Testing - 2 • Need to demonstrate the validity of the raw data sent from the database to the WebApp and the validity of the transformations applied to the raw data. • Need to test validity of dynamic content object formats transmitted to the user and the validity of the transformations to make the data visible to the user.
  20. 20. 20 User Interface Testing - 1 • Interface features are tested to ensure that design rules, aesthetics, and related visual content is available for user without error. • Individual interface mechanisms are tested using unit testing strategies. • Each interface mechanism is tested in the context of a use-case of navigation semantic unit (e.g. thread) for a specific user category
  21. 21. 21 User Interface Testing - 2 • Complete interface is tested against selected use-cases and navigation semantic unit to uncover interface semantic errors • Interface is tested in a variety of environments to ensure compatibility
  22. 22. 22 Testable Web Mechanisms - 1 • Links – each link is listed and tested • Forms – check labels, field navigation, data entry, error checking, data transmission, meaningful error messages • Client-side scripting – black box testing and compatibility tests
