In her session at Testμ 2023, Marit van Dijk, a Developer Advocate at JetBrains with extensive experience in software development, emphasized the critical role of testing in enhancing software quality within the CI/CD framework. She highlighted how testing not only verifies solutions and prevents errors but also aids in shaping software design and addressing architectural flaws. Marit discussed various strategies for integrating quality into software, such as Test-Driven Development (TDD) and considering testing from the start of development. She underscored the importance of using appropriate testing tools, ranging from unit tests to performance testing frameworks, and emphasized the necessity of maintaining reliable, meaningful tests to ensure software confidence. Marit also explored the testing pyramid and honeycomb model, advocating for a focus on unit testing and integration testing for microservices. She stressed the involvement of developers in crafting and maintaining acceptance tests and shared insights on using tools effectively for their intended purposes. Additionally, Marit warned against the pitfalls of flaky tests, encouraged readability and maintenance of test code, and discussed the integration of security and performance testing into the development cycle to proactively address potential issues.
