What Is Iterative STLC ?

The iterative software testing life cycle (STLC) involves repeating phases of the testing process to improve software quality through continuous feedback and refinement. Here is a structured breakdown:

Iterative Software Testing Life Cycle (STLC):

• Requirements analysis
• Gather and analyze requirements.
• Identify testable requirements.
• Prepare a requirements traceability matrix (RTM).

Test planning:

• Define the scope and objectives of testing.
• Develop a testing strategy.
• Estimate testing effort and resources.
• Prepare a detailed test plan.
• Identify training needs.

Test case development:

• Create detailed test cases.
• Prepare test data.
• Develop automated test scripts (if applicable).
• Review and get your test cases approved.

Setting up the test environment:

• Define hardware and software requirements.
• Set up a test environment.
• Configure the test environment and prepare the test data.
• Perform smoke testing to ensure environmental stability.

Test execution:

• Execute test cases.
• Record defects and track them to closure.
• Retest and perform regression testing as needed.
• Update test cases based on feedback.

Bug reporting and tracking:

• Log and report bugs in the bug tracker.
• Assign severity and priority to defects.
• Work with development team to resolve.
• Defects on the track until the closure.

Closing the test:

• Ensure all scheduled tests are performed.
• Document test results.
• Prepare a test summary report.
• Hold a final test meeting.
• Archive test artifacts for future reference.

Iteration and feedback loop:

• Review feedback from previous iteration.
• Identify areas for improvement.
• Adjust plans and strategies based on feedback.
• Repeat the cycle for the next iteration.

Key features of iterative STLC:

• Continuous improvement: Each cycle involves feedback, improving process and product quality.
• Flexibility: Adapts to changes in requirements and scope, ensuring that the product meets current needs.
• Collaboration: Requires close collaboration between testing, development, and other stakeholders.
• Early Defect Detection: Iterative testing helps detect and fix defects early, reducing overall cost and time.

Advantages of iterative STLC:

• Improved quality: Continuous testing and feedback loops lead to higher product quality.
• Reduced risk: Early and frequent testing reduces the risk of serious defects.
• Better use of resources: Efficient use of resources through planned iterations and feedback.
• Customer satisfaction: Frequent releases and updates ensure that the product meets customer expectations.
