Why we perform stress-testing, resolution-testing and cross- browser testing?

Stress Testing: - We need to check the performance of the application.

Def: Testing conducted to evaluate a system or component at or beyond the limits of its specified requirements

 

 

Resolution Testing: - Some times developer created only for 1024 resolution, the same page displayed a horizontal scroll bar in 800 x 600 resolutions. No body can like the horizontal scroll appears in the screen. That is reason to test the Resolution testing.

 

Cross-browser Testing: - This testing some times called compatibility testing. When we develop the pages in IE compatible, the same page is not working in Fairfox or Netscape properly, because

most of the scripts are not supporting to other than IE. So that we need to test the cross-browser Testing

 

There are two sand clocks(timers) one complete totally in 7 minutes and other in 9-minutes we have to calculate with this timers and bang the bell after completion of 11- minutes!plz give me the solution.

Start both clocks

2. When 7 min clock complete, turn it so that it restarts.

3. When 9 min clock finish, turn 7 min clocks (It has 2 mints only).

4. When 7 min clock finishes, 11 min complete.
