SAP HANA is a large enterprise database management system, based on roughly 40 million lines of code tested by over 900 000 tests. See https://link.springer.com/article/10.1007/s13222-022-00426-x
Testing of SAP HANA is severely impacted by test flakiness. Test flakiness describes the situation that a test execution may pass and fail for the same code. Such test results are not reliable. Developers lose trust in flaky tests and the overall quality signal provided by tests is weakened.
In the context of flakiness analysis for SAP HANA, you will analyze data and contribute to changes that improve test flakiness with the goal to understand test flakiness, reduce flakiness and increase resilience against current and future flakiness sources.
