Self-healing test automation is a modern approach to automated testing that solves the challenges of traditional test automation by automatically detecting and fixing issues in test scripts whenever the state of the software application under test changes. This approach reduces manual efforts required for test maintenance, improves test coverage, and minimizes test failure. It works by identifying elements using multiple attributes, performing test execution according to pre-defined steps or instructions, identifying issues when an element cannot be located using its primary attribute, implementing self-healing mechanisms to update the test script with new identifiers or attributes, and integrating with AI technologies to increase efficiency in software testing. Tools like Selenium can also be used for self-healing test automation, which helps in increasing the reliability of test suites and reducing errors like test flakiness.
