Developed a CI-ready test infrastructure for the Mustache Template within the flutter/packages repository, focusing on improving test automation and maintainability using Dart and CI/CD practices. The work involved reorganizing and splitting test files to enhance compatibility with continuous integration workflows, as well as introducing automated retrieval and generation of specification-based tests. By separating generated tests from handwritten ones and implementing mechanisms to skip unsupported specs, the developer enabled more reliable and traceable test runs via dart test. These changes laid the foundation for expanding mustache spec coverage and streamlined future updates as the specification evolves, supporting robust automated testing.
