The systems and methods that determine tests that may be executed in parallel during regression testing of an analytics application are provided. Multiple tests that test functions of the analytics application are accessed from a test automation suite. For each test, data sources that provide data to the analytics application during the test are identified. The tests are aggregated into temporary groups according to the identified data sources. The test groups are generated from the temporary groups such that each test group comprises tests that are associated with non-overlapping data sources. The regression testing is performed on the application by executing the test groups in parallel.
