How many Phases are there in testing life cycle???

No actually there are 7 ..and the rest four are...

1)Test Design
2)Construction and verification
3)Test Design
4)Final Testing and Implementation

Yeah very true but ..But these are the basic in software testing life cycle is to control/deal with software testing – Manual, Automated and Performance.

There are six I suppose but I am familiar with only three

1)Testing Cycles
2)Test Analysis
3)Post Implementation

Different stages in STLC:
* Requirement Analysis
* Test Planning
* Test Case Development
* Test Environment Setup
* Test Execution
* Test Cycle Closure - Testing team will meet , discuss and analyze testing artifacts to identify strategies that have to be implemented in future, taking lessons from the current test cycle. The idea is to remove the process bottlenecks for future test cycles and share best practices for any similar projects in future.
Activities:

- Evaluate cycle completion criteria based on Time,Test coverage,Cost,Software,Critical Business Objectives , Quality
- Prepare test metrics based on the above parameters.
- Document the learning out of the project
- Prepare Test closure report
- Qualitative and quantitative reporting of quality of the work product to the customer.
- Test result analysis to find out the defect distribution by type and severity.

Deliverables:
- Test Closure report
- Test metrics
