I have extensive experience with automated testing frameworks such as Selenium and Cucumber. I've successfully implemented these tools in multiple projects, automating regression and integration tests to improve efficiency and reduce manual testing efforts. My approach involves creating robust test scripts that are maintainable and scalable, ensuring comprehensive test coverage and early detection of defects.

In fast-paced environments, I prioritize tasks based on risk assessment and business impact. I collaborate closely with the development team to understand the critical functionalities and potential risks. Using agile methodologies, I adapt my testing strategy to focus on high-priority features first, ensuring that the most critical aspects of the application are thoroughly tested and ready for release.

To ensure comprehensive test coverage, I start by thoroughly understanding the requirements and designing test cases that cover all possible scenarios, including positive, negative, and edge cases. I also use tools like test management systems to track and manage test cases effectively. Additionally, I advocate for continuous integration and automated testing to regularly validate the application's functionality and identify issues early in the development cycle.

When a critical bug is found post-release, my immediate focus is on mitigating the impact and providing a quick fix. I work closely with the development team to prioritize the bug fix and coordinate with the release management team to expedite the patch deployment. Simultaneously, I conduct a root cause analysis to understand how the bug escaped detection and refine our testing processes to prevent similar issues in the future.

Black-box testing involves testing the functionality of an application without knowledge of its internal code structure or implementation. Testers focus on the input and output without considering how the system processes the data. In contrast, white-box testing, also known as structural testing, requires knowledge of the internal workings of the application. Testers examine the code, logic, and structure to ensure that all paths are tested and the code behaves as expected.
