In one embodiment, a method for automating regression testing of a software application is disclosed. The method includes receiving, by a test automation system, input data associated with the regression testing of the software application and predicting, by the test automation system, a test automation framework for execution of a regression test suite by analyzing the input data. Further, the method includes obtaining, by the test automation system, test scenarios from execution of historical regression test suites upon predicting the test automation framework and identifying, by the test automation system, availability of devices for executing each test scenario based on one or more device parameters. Further, the method includes transmitting, by the test automation system, information corresponding to the test scenarios to the identified devices based on the availability to automate the regression testing of the software application.
