Software Testing Life Cycle:
- Software Testing Life Cycle is a process of different activities which is performed in a systematic manner that are used to perform for the different type of testing activities of the Software/Application.
- STLC defines a series of activities conducted to perform the "Software Testing."
STLC is carried out in five different phases:
1. Test Plan and Control
2. Test Requirement Analysis and Design
3. Test Implementation and Execution
4. Evaluating Exit Criteria and Reporting
5. Test Closure
Phases of STLC:
STLC Cycle
1. Test Plan and Control:
- In test Planning, the planning of all the testing activities is getting done.
- Test plan helps to identify the Scope of testing (i.e. What to be tested? What not to be tested? What resources are required? Any training is required?)
- We can create the test plan with the help of "SRS, Development Plan, and Project Plan."
- Test Plan is important to avoid random testing or to miss to random testing activities.
- Test Plan is to get done by the Test Manager/Test Lead.
- Test control measures and analyze the result of review and testing.
- Test control prepares the Documentation, Monitoring and Exit criteria.
Input- "SRS Documents", "Development Plan", and "Project Plan"
Output- Test Plan Document and Scope of testing.
2. Test Requirement Analysis and Design-
- This phase of STLC defines "What's to be tested?"
- In this phase different scenarios are to be defined depends on the condition.
- Senior Testers do the Analysis with the help of SRS and Design Templates.
Input- "SRS Document" and "Design Templates"
Output- Test Scenario (What to be tested ?)
3. Test Implementation and Execution:
- In this phase Senior Tester is going through the Test Scenario and create a new document known as "Test Case".
- The created test cases are given to the junior tester to execute the test case.
- Junior tester executes the test cases and check there is a defect in the software or not?
- After testing the software and then create the defect report and also mention in the execution log.
Input- "SRS Document" and "Test Scenario"
Output- Test case Execution and Execution Report
4. Evaluating Exit Criteria and Reporting:
- In this phase STLC defines where to stop the software testing activities.
- After the successful installation of the software, exit criteria has been decided.
e.g. (i) 100% Coverage: It means software should be passed all the testing work properly with no error and software need to work smoothly.
(ii) 80% - 20% Coverage: It means 80% of the total software should complete the testing activities and remaining 20% of testing activities can allowed with minor defects only.
Input- Test case execution report
Output- Testing activities are get done
5. Test Closure:
- In the Test Closure all the testing activities which are done that we can close the testing activities with the permission of senior management.
- After that, submit the all documents to the management for the future reference and their documents are known as "Test Deliverable"
Input- Instruction of closing testing activities
Output- Closing of test case and submitting Test report
