Upgrade is provided to a cloud application in a cloud environment of a customer. A task list for an upgrade testing for the cloud application is automatically triggered at a test cloud infrastructure. Execution processes of the cloud application are listed. Available test scripts for the processes are defined. Iterations over the test scripts are performed to determine relationships between scripts and processes. The iterations over the test scripts may be executed by a data mapping logic. For a process from the list, a corresponding test script and relevant data for the test script from a database of the cloud application are determined. The relevant data and actions from the test script are mapped. A test data variant is generated for execution based on the relevant data and actions of the test script. The test results are collected and analyzed.
