Worked on the workleap/renovate-config repository to stabilize the test suite following a major upgrade of Workleap.Extensions.Mongo. Addressed failing snapshot tests by updating package references and aligning expected messages with the new extension behavior, ensuring continued compatibility across the suite. To maintain CI reliability, marked flaky Terraform provider tests as skipped with clear justification, reducing noise in nightly runs. Focused on sustaining a robust foundation for future upgrades and smoother downstream integration. Utilized C# for test adjustments and applied skills in CI/CD, dependency management, and unit testing to deliver targeted improvements that enhanced the repository’s stability and maintainability.
