Test life cycle:
Analysis the SRS->Outline and scope is drawn->Test Plan is 
prepared->Test case written->Test data prepared->test case 
execution->Defect tracking ->Defect report is prepared & 
send to devloper->After Fixing Regration testing->If fixed 
despached to customer->if not fixed send to devoloper.

total there are si phases in test life cycle system

1)test planning 
2)test design
3)test execution
4)result analysis
5)bug tracking
6)report analysis

Test life cycle dentifies what test activities to carry out 
and when (what is the best time) to accomplish those test 
activities. Even though testing differs between 
organizations, there is a testing life cycle.

They are 6 (Generic phases) involved in Test life cycle. 
Viz:

1. Test Planning, 
2. Test Analysis, 
3. Test Design, 
4. Construction and verification, 
5. Testing Cycles, 
6. Final Testing and Implementation and 

7. Post Implementation.

1.Test Planing
2.Test Analysis and Design
3.Test Implementation
4.Evaluating Exit Criteria
5.Test Closer
