AI creates auto E2E tests

End-to-end testing is the software check that clicks through an app the way a customer would, and DevAssure says its O2 agent now writes those tests from code changes instead of waiting for a human to script them. (devassure.io) On DevAssure’s O2 page, the company says the agent watches a branch diff or a specific commit, maps affected user flows, finds existing tests, generates missing ones, updates impacted cases, and then runs the session automatically. The page shows one sample run with 18 changed files, 9 affected flows, and 27 tests generated. (devassure.io) DevAssure also says O2 is built into Visual Studio Code and can be triggered from the editor or command line with branch, commit, environment, headless, archive, and target Uniform Resource Locator options. The company says results are zipped and saved with session identifiers for continuous integration reporting and traceability. (devassure.io) The underlying problem is old and expensive: end-to-end tests are the final release check, but they are slow to write and brittle to maintain as apps change. DevAssure’s own February 19, 2025 guide says manual end-to-end testing delays releases, while automated suites often go flaky because user interfaces, networks, and data states keep moving. (devassure.io) DevAssure is pitching O2 as a way to move that work earlier into the developer workflow, so the test plan follows the code diff instead of a separate quality-assurance handoff. On its homepage, the company says O2 “understands the intent behind every commit” and uses automated diffing to identify the “blast radius” of a change across an application. (devassure.io) That fits a broader push in software tools to treat testing less like a separate department and more like an always-on layer inside the editor and the delivery pipeline. In an April 22, 2025 funding announcement, DevAssure said its system converts Figma mock-ups and live code into executable tests that repair themselves as the product evolves. (businessnewsthisweek.com) The company was launched in 2024 by Badri Varadarajan, Divya Manohar, and Santhosh Selladurai, according to that same April 2025 announcement. DevAssure said the founders previously worked on Ally.io’s release-engineering stack before Microsoft acquired Ally.io, and that the new capital would fund more integrated development environment and continuous integration and continuous deployment integrations in India and the United States. (businessnewsthisweek.com) DevAssure has not published a detailed public benchmark for O2’s test quality, false positives, or failure rates on the product pages reviewed here. What it has published is the workflow: point the agent at a diff, let it decide what changed, and turn that delta into executable end-to-end coverage inside the release pipeline. (devassure.io)
