100 Days of System Design Questions challenges

Design a system for automated testing and test coverage analysis to ensure the quality and reliability of software applications. The system should support various types of testing, including unit tests, integration tests, and end-to-end tests, and provide comprehensive coverage analysis to identify gaps in test coverage. Consider factors such as test automation frameworks, continuous integration (CI) pipelines, test execution environments, and reporting mechanisms in your design. Discuss how you would automate the execution of tests as part of the software development lifecycle, including integration with version control systems and deployment pipelines. Additionally, address how you would measure and report test coverage metrics to track the effectiveness of testing efforts and prioritize areas for improvement. Provide insights into the technologies, tools, and best practices you would employ to implement this automated testing and test coverage analysis system effectively.
