Developed and delivered Kotest ClasspathRootSelector support for SBT compatibility within the kotest/kotest repository, focusing on improving test discovery and continuous integration reliability for Kotlin projects. The work involved adapting the shouldRunTests logic to align the Kotest engine with SBT’s test discovery mechanisms, ensuring consistent behavior across tools. Collaborated on cross-repository commits to address and close related issues, working closely with other contributors. Utilized Kotlin and JUnit, applying expertise in software testing and test automation to enhance cross-tool integration. The feature enables more reliable CI pipelines for SBT-based projects by standardizing test selection and execution within the Kotest framework.
