1. Categorize as per the main flow& high priority test 
cases, more defect density area covering test case, failed 
test cases and randomly picked test cases etc.

2. It is performance team responsibulity,
 i.e. they validate the application by appling more number 
of vertuial user at a time to check the load, stress & thus 
point

3. Validating the application as per the Expected and 
actual result

4. GUI, Performance, Security etc

5. As per the preyuarity

6. Good requirement - which covered all the business 
requrements
 Bad requirement - which does not covered all the business 
requrements, not able to understand, not clear

7. its field level verification, where we validate wheather 
respective application is beheaving as per the requiorements

8. If u prepare RTM (Requirement Trasability Matrix), it 
will be easy to track the test case and there requirements

9.Tester activity starts after BRS and SRS are ready
execution phase starts after build is ready

10. Test bed - set of test cases (whech is related to 1 
main funtionality)
Test Environment - Hardware and software setup in mechine 
to run the application

13. It discribe one perticular action of an application as 
per the requirement, it is used at the time of writing test 
cases

14. Mismatch\ defect found at the time of exetution and you 
are not able to execute furture

15. The impact of field inputs need to store in back end 
i.e table or records. 

In back end testing we test, wheather given inputs in front 
end (Field) are stored in respective tabler form or not. to 
validate this back end (Table or records) we will use SQL
