A system and computer-implemented method for efficiently predicting software testing schedule of one or more applications is provided. The system comprises a user interface configured to facilitate creating a base execution plan for software testing of an application and receive values of one or more factors affecting test execution. The system further comprises a test management tool interface configured to receive data related to test execution from one or more test management tools. Furthermore, the system comprises a schedule prediction module configured to analyze the received values of one or more factors affecting test execution and further configured to modify the created base execution plan based on the received data related to test execution and the analyzed values of the one or more factors affecting test execution to generate one or more modified execution schedules.
