Worked on the zio-http repository to improve the maintainability of the test infrastructure by addressing dependency complexity in the TestKit module. Focused on Scala-based testing, the contribution involved removing an unnecessary Server type tag from the TestServer default layer, which reduced explicit dependency requirements and decoupled the testkit from changes in the Server type. This targeted bug fix streamlined the dependency surface, making the codebase more modular and resilient to future updates. The changes facilitated faster onboarding for contributors and simplified the build process, reflecting a thoughtful approach to dependency management and codebase maintainability using Scala and testing best practices.
