The present disclosure involves systems, software, and computer implemented methods for testing applications on multiple system landscapes. In one example, a method may include identifying instructions to test a plurality of system landscapes, executing a test of a first system landscape from the plurality of system landscapes, validating a response received from the first system landscape by a user associated with the testing, executing tests of at least a subset of the remaining plurality of system landscapes which includes sending requests including the predefined input to the entry point of each of the subset of the remaining plurality of system landscapes, receiving responses from the subset of the remaining plurality of system landscapes, and comparing each received response to the validated response from the first system landscape, and in response to the comparison, generating a result set of the comparison of each received response to the validated response.
