Worked on the AzureAD/microsoft-identity-web repository, focusing on enhancing security and reliability in dSTS token acquisition flows. Developed and overhauled integration and unit testing strategies using C# and HTTP mocking, introducing robust tests for token handling and explicit authority validation. Improved the test infrastructure by leveraging MockHttpClientFactory, enabling isolated, network-free tests suitable for continuous integration environments. Addressed CI build stability by resolving dependency issues, ensuring consistent test execution. The work emphasized backend development and integration testing, reducing configuration errors and improving feedback on security-critical paths, while streamlining the testing process to accelerate developer onboarding and maintain high code quality.
