Best practices for shift-left testing

Shift-left testing is an approach that moves the testing phase earlier in the development life cycle, enabling agile teams to identify and resolve bugs before they become costly and time-consuming. This method has several advantages, such as automating continuous integration and delivery (CI/CD) workflows, encouraging collaboration between developers and testers, and improving application quality for end users. However, adopting shift-left testing requires substantial changes to existing processes, which can be challenging. To address these challenges, best practices include enabling developers to test their code, optimizing test infrastructure, creating builds that fail fast, and monitoring the performance of CI/CD pipelines. By implementing these practices, teams can improve development efficiency and reduce time to market for new features.
