Testsigma is an open-source test automation platform for end-to-end testing that works out of the box. It's built to enable Agile teams to collaboratively plan, develop, execute, analyze, debug, and report on their automated testing—for websites, native Android and iOS apps, and APIs. The platform is built with Java, but the automated tests are code-agnostic. Through built-in NLP Grammar, teams can automate user actions in simple English or generate airtight test scripts with the Test Recorder. It has built-in visual testing, generators for parametrized or data-driven testing, a test lab on cloud, integrations with CI tools, and an AI that automatically fixes unstable elements, isolates regression-affected scripts, and provides suggestions for quick RCA on test failure. Testsigma can replace tens of different tools in the QA toolchain to enable teams to test easily throughout their continuous delivery pipeline.
