1. Software Testing Life Cycle Process
A software testing life cycle (STLC) is a set of
steps used to test software products.

2. STLC Stages
1. Specifications phase
2. Preparing Phase
3. Research phase
4. Style Phase

3. STLC Stages
5. Execution Phase
6. Performance Phase
7. Summary Phase
8. Closing Phase

4. 1. Specification Phase
During this stage of STLC, evaluate and study
the needs.
This stage helps to recognize the opportunity of
the examining.

5. 2. Preparing Phase
In this stage we recognize the activities and
resources which would help to meet the
examining goals.

6. 3.Research & 4. Style Phase
Research STLC stage describes “WHAT” to be
tested.
Style STLC stage describes “HOW” to evaluate

7. 5.Execution & 6.Performance Phase
The major task in Execution STLC stage is of
development of the specific test situations.
Performance Phase is the Software Testing Life
Pattern stage where the particular execution
occurs.

8. 7. Summary & 8. Closing Phase
Summary STLC stage focuses on the quit
requirements and confirming.
Closing Phase Examine for the finalization of
quality.
