How Do You Approach Writing Test Cases for a New Feature or Functionality?

When approaching the task of writing test cases for a new feature or functionality as a Manual Tester, I follow a structured approach to ensure comprehensive test coverage:

1. Requirement Analysis: I thoroughly review the requirement documents, user stories, and any other relevant materials to understand the expected behavior of the new feature.
2. Identify Test Scenarios: Based on the requirements, I identify different test scenarios that need to be validated to ensure the feature works as intended.
3. Write Test Cases: I then proceed to create detailed test cases for each identified test scenario, including preconditions, steps to execute, expected outcomes, and any input data needed.
4. Review and Refine: I collaborate with stakeholders, developers, and other team members to review the test cases, gather feedback, and refine them for accuracy and completeness.
5. Execution and Reporting: Once the test cases are finalized, I execute them systematically, log any defects found, and provide detailed reports on the test results and overall test coverage.

By following this structured approach, I ensure that the test cases I write effectively validate the new feature or functionality, helping to deliver a high-quality product to end users.
