Aspects of the disclosure relate to conducting automated software testing using a centralized controller and one or more distributed test host servers. A computing platform may receive a test execution request. Subsequently, the computing platform may retrieve test specification details information and may identify one or more tests to execute. Then, the computing platform may generate one or more local test execution commands directing a test host server farm to execute the one or more tests. In addition, the one or more local test execution commands may direct the test host server farm to locally construct one or more command line instructions to be executed by the test host server farm to complete the one or more tests. Thereafter, the computing platform may send the one or more remote test execution commands to the test host server farm.
