In my previous role as a Testing Coordinator, I utilized tools like JIRA and TestRail extensively. I managed test cases, tracked defects, and coordinated with the development team to ensure timely resolution. I also integrated automated testing tools like Selenium to streamline the testing process and improve efficiency.

I prioritize testing tasks based on the project's criticality, the risk associated with each feature, and the timeline for release. I use a risk-based approach to identify high-priority areas that need immediate attention and allocate resources accordingly. Regular communication with project managers and stakeholders helps in aligning priorities effectively.

To ensure adequate test coverage, I start by reviewing the requirements and design documents to identify all functional and non-functional aspects that need testing. I then create a comprehensive test plan that includes unit, integration, system, and acceptance tests. I also conduct exploratory testing to uncover any hidden issues and ensure all critical paths are covered.

When a critical defect is found close to the release date, I immediately escalate it to the project manager and development team. I provide detailed information about the defect, including its impact and potential workarounds. We then assess the risk and decide whether to delay the release, fix the defect, or provide a mitigation plan. Clear communication and a collaborative approach are key in such situations.

I maintain effective communication by holding regular meetings with the development team, project managers, and stakeholders to discuss progress, issues, and upcoming tasks. I also use collaboration tools like Slack and Microsoft Teams for real-time updates. Additionally, I ensure that all documentation is up-to-date and accessible to everyone involved, fostering transparency and collaboration.
