Abstract: A software-testing automation system for tests a plurality of deployed images that are spread across multiple software platforms. Each deployed image includes a test component configured to accept a connection on a known testing port, and the test component for a deployed image is inserted in a development environment and is then integrated into the image upon deployment. The system includes a test engine configured to run a plurality of tests on the plurality of deployed images. The test engine runs a test on an image under test by requesting a connection to the corresponding test component on the known testing port and sending commands over the connection. A user interface connected to the test engine allows a user to control the test engine and to view test results. An alternative embodiment utilizes a well-known test engine interface and a plurality of adaption layers to connect to external test tools.
