Worked on the dotnet/aspire repository to enhance test infrastructure by unifying integration test templates across MSTest, NUnit, and xUnit. Focused on robust resource management in C#, implementing proper disposal of HTTP clients and responses using using statements and ensuring cancellation token awareness throughout the test suite. Standardized test class naming conventions and automated Aspire version data generation to promote consistent test coverage and easier onboarding. These improvements targeted stability and maintainability, reducing test flakiness and improving CI reliability. The work emphasized integration testing, template development, and unit testing, ultimately supporting faster release validation and more reliable feedback for contributors.
