Virtuoso QA offers automated regression testing solutions for web-based applications, including major enterprise platforms like Dynamics 365, Salesforce, ServiceNow, and Workday, which frequently receive updates from their vendors. The regression testing suites operate concurrently on a managed cloud infrastructure, either according to a set schedule or triggered through CI/CD pipelines. The system incorporates Touchstone, Virtuoso's intelligent layer, which employs AI agents to analyze and fix regression test failures. When a test does not succeed, Touchstone categorizes the issue, distinguishing between faults in the application and problems with the tests themselves, while also suggesting corrective actions. In the event of application modifications, it pinpoints the tests that are impacted and recommends necessary adjustments. All changes necessitate human validation before they are implemented, and each modification is version-controlled and can be reversed if needed. The execution process is deterministic, ensuring that any test failures indicate genuine alterations in the application rather than discrepancies between test executions.
