Worked on the bazelbuild/rules_apple repository to deliver support for the Swift-Testing framework within the iOS XCTest Runner on iOS 17, enabling unified test reporting across both XCTest and swift-testing. This involved modifying shell scripts to detect and interpret outputs from multiple test frameworks, ensuring accurate reporting of test counts and failures. Integration tests were added to validate the runner’s behavior with passing, failing, and empty swift-testing suites, improving regression coverage and reliability. The work leveraged skills in CI/CD, shell scripting, and iOS development using Swift, enhancing test automation and reducing barriers to adopting modern testing strategies.
