Software Testing Life Cycle And Software Testing Operations

The software testing life cycle has these phases:

1. Requirements study: Understand the client’s requirements and prepare functional documentation.
2. Test planning: Plan testing activities around the project’s requirements and prepare the test plan.
3. Test case design: Identify testing scenarios and design the corresponding cases.
4. Map requirements to test cases and prepare a requirements traceability matrix (RTM).
5. Execute test cases and report defects.
6. After defects are fixed, carry out retesting and regression testing.
7. Prepare test reports.
8. Complete testing activities.

Requirements Study

This process includes:

• Prepare the requirements traceability matrix.
• Set priorities and the approach for each module.
• Identify areas for automated and manual testing.

Test Case Design And Development

This process includes:

• Prepare test cases and, where automation is used, test scripts.
• Prepare test data.

Test Execution

Test execution includes:

• Execute test cases.
• Log defects in a bug tracking tool.
• Document test results.
• Use the RTM to map defects to requirements.
• Track each defect’s status.

Test Closure Test closure includes:

• Prepare metrics covering test coverage, cost, time and quality.
• Prepare the test closure report.
• Calculate the distribution of defects by type and severity.
• Prepare causal analysis and resolution (CAR).

Test Process Analysis

Analyze the test process before testing begins. The documents used to establish what to test are called the test basis. They include the SRS, system design, architecture and interface documentation. Use them to understand the system and identify test conditions. Prioritize those conditions, then create test cases.
