Understanding Software Testing: Roles, Processes, and Best Practices
In today's fast-paced software development world, software testing is essential for delivering high-quality, reliable products. From traditional Waterfall development to modern Agile practices, software testing continues to evolve. In this post, we explore common software testing roles, examine different development models, and walk through a typical testing workflow.

Key Software Testing Roles
Testing can be handled by dedicated professionals or even by developers and stakeholders, depending on the team structure. Here are some of the most common roles in software testing:
Test ManagerOversees the entire QA process and team.Test LeadCoordinates the testing process and team efforts.Test AnalystAnalyzes requirements and writes detailed test cases.Test DesignerDesigns efficient and effective test scenarios.TesterExecutes tests and logs defects.Automation DeveloperBuilds scripts for automated testing.Test AdministratorManages test tools and environments.

Waterfall vs. Agile Testing Approaches
Different development methodologies approach software testing with varying strategies and timelines.

Waterfall Development
In the Waterfall model, testing is typically done after development is complete and before the product is released. While this allows for a clear structure, it often compresses the testing time when delays happen in development.
Some experts recommend starting testing activities as early as the requirements phase to improve quality and reduce risks.

Agile Development
Agile testing is a continuous process. Testers are integrated into development teams and collaborate closely with developers. A popular practice is Test-Driven Development (TDD), where test cases are written before the code itself. Agile teams also use Continuous Integration (CI) to run automated tests during each build.

Typical Software Testing Process (Waterfall Model)
Here’s a simplified view of the testing lifecycle in a traditional development environment. These stages also apply to other methodologies with some variations.
Start↓Requirements AnalysisTesters review project requirements to identify testable elements and edge cases.
↓Test PlanningDevelop a test plan, strategies, and define test environments (testbeds).
↓Test DevelopmentCreate test cases, scripts, and data based on the requirements.
↓Test ExecutionRun tests and log any defects found.
↓Test ReportingGenerate metrics and summaries of test results.
↓Test Result AnalysisDevelopers and stakeholders analyze defects to determine which should be fixed or deferred.
↓Defect RetestingAfter bugs are fixed, testers retest to confirm resolution.
↓Regression TestingEnsure recent changes haven’t broken existing functionality.
↓Test ClosureFinalize documentation, store key lessons learned, and archive test artifacts.
