Description: The ‘Test Log’ is an essential component in test-driven development (TDD) and continuous integration, especially in automation environments. It refers to a document or system that collects and organizes the results of software testing. This log includes critical information such as the status of each test (passed or failed), as well as details about any errors or failures encountered during the testing process. The importance of a test log lies in its ability to provide visibility and traceability throughout the software development lifecycle. It allows developers and quality teams to quickly identify issues, track fixes, and ensure that new features do not introduce regressions. Additionally, a well-maintained log can serve as a reference for audits and reviews, facilitating communication among team members and other stakeholders. The test log integrates with CI/CD pipelines, enabling test automation and generating reports that help teams make informed decisions about the status of the software under development.
