Suppose you’re working on a new e-commerce platform. The QA team would review the requirement document to ensure that all necessary features, such as payment processing, user authentication, and product display, are clearly defined and measurable for testing purposes.
2. Design Phase
QA Role: Design Test Strategy and Test Plan
During the design phase, the software architecture and detailed designs are defined. The QA team’s responsibility here is to start planning the testing process, including creating a test strategy, identifying the testing tools, and drafting the test plan. The focus is on creating test cases and ensuring that the design will meet the desired requirements.
- Responsibilities:
- Collaborate with developers to understand the design architecture.
- Create a test strategy outlining the overall approach to testing.
- Develop the test plan, which includes resources, timelines, and scope.
- Identify testing types (functional, non-functional, integration) based on the design.
- Example:
A QA tester working on a banking application might design test plans to validate security features such as multi-factor authentication, ensuring that these security protocols are built according to the design specifications.
