The present disclosure involves systems, software, and computer implemented methods for executing integration scenario regression tests in customer landscapes. One example method includes identifying a request to create a test case for an integration scenario for a cloud platform customer. The test case is created for the scenario, including enabling the test case to run in an isolated customer environment specific to the customer. An update to the cloud platform is identified. The update is provisionally applied to the cloud platform for the customer. The test case is executed in the isolated customer environment, to test the scenario for the customer. A determination is made as to whether execution of the test case succeeded. In response to determining successful test case execution, the update to the cloud platform is finalized for the customer. In response to determining unsuccessful test case execution, the update is rolled back for the customer.
