I have extensive experience with automated testing tools such as Selenium, JUnit, and TestNG. I have used these tools to create, execute, and maintain automated test scripts for web and mobile applications. My focus has always been on improving test coverage and efficiency while reducing manual effort. I also integrate these tools with CI/CD pipelines to ensure continuous testing and early detection of defects.

When creating a test plan, I start by understanding the project requirements and objectives. I collaborate with stakeholders to identify key functionalities, risks, and priorities. Based on this, I define the scope, test objectives, resources, and timelines. I also outline test strategies, including manual and automated testing approaches, and ensure the plan aligns with the overall project goals to deliver a high-quality product.

To ensure comprehensive test coverage, I use a combination of requirement traceability matrices, risk-based testing, and exploratory testing. I map test cases to requirements to ensure all functionalities are tested. I prioritize high-risk areas and use exploratory testing to uncover edge cases. Additionally, I leverage automation for repetitive and regression testing to maintain coverage as the product evolves.

When I identify a defect, I document it thoroughly, including steps to reproduce, expected vs. actual results, and screenshots or logs. I categorize defects based on severity and priority and log them in a tracking tool like JIRA. I communicate defects to the development team promptly, providing clear and concise information to facilitate quick resolution. I also follow up to ensure fixes are verified and retested.

In a previous project, I encountered a complex integration issue between multiple microservices. The challenge was reproducing the issue consistently. I collaborated with developers to analyze logs and simulate scenarios. By isolating the problem, I identified a timing issue in API calls. I proposed a fix, which was implemented, and I validated the solution through rigorous regression testing, ensuring the issue was resolved without impacting other functionalities.
