Andrei Moseev focused on improving the stability and reliability of integration tests for the folio-org/folio-integration-tests repository. He addressed persistent test flakiness by re-enabling module loading within the test infrastructure, ensuring that all necessary modules were available during test execution. This work involved configuration management and integration testing, primarily using Groovy to modify and maintain the test environment. By restoring proper module availability, Andrei enabled more accurate test coverage for module-based features and facilitated faster diagnosis of issues. The changes resulted in more reliable continuous integration feedback, reflecting a targeted and in-depth approach to test infrastructure maintenance and improvement.
