In an exemplary computer implemented method for executing test scripts, a computer receives a test file having a set of one or more unique test script identifiers associated with a test script stored in a test script repository. The computer fetches a test script from the test script repository according to the test file, and stores the test script as a queued test script in a buffer memory. The computer provides instructions to a processor to execute the queued test script, and then receives results. The computer continuously monitors an action request queue configured to received action requests to change a test script or change the set of test script identifiers. The computer executes the action request before storing the next queued test script in the buffer memory.
