Worked on the equinor/ert repository to deliver a test execution performance enhancement focused on optimizing queue-based job completion tests. The approach involved removing fixed sleep intervals and introducing a callback mechanism to mark job completion, which reduced CPU usage during continuous integration and accelerated test execution. This change improved the determinism and reliability of the test suite, enabling faster feedback cycles for developers and more cost-efficient CI pipelines. The work was implemented using Python and leveraged skills in test automation, testing, and unit testing. Over the period, contributed one feature that addressed performance and reliability in automated testing workflows.
