CoTester
VerifiedTestGrid's AI testing agent that writes, runs and self-heals software tests
Product preview
CoTester
What it is
CoTester is a software testing agent built by TestGrid for QA and engineering teams. You can link or upload user stories from Jira, and its authoring agent produces test cases and test logic, generating code in Selenium Java or Appium Java that you can download. Tests run across real browsers and devices on TestGrid's infrastructure, while a vision language model interprets screens the way a human tester would. An auto-heal engine called AgentRx updates tests when the interface changes, and the agent flags and logs bugs during runs. Teams can switch between scriptless, record-and-play and code modes, schedule regressions, and approve key steps before CoTester proceeds.

Editor's notes
More context from AI BirdView
CoTester is designed to act like a dependable QA teammate rather than a black box. It learns your product context, writes tests from your existing stories, and pauses at important checkpoints so your team stays in control, which addresses a common worry about handing testing to an AI.
- Turns Jira user stories into test cases and full test logic
- Generates Selenium Java or Appium Java code that you can download and keep
- Runs tests on real browsers and devices with live feedback
- AgentRx updates tests when the interface shifts, including larger redesigns
- Detects and logs bugs during runs and supports scheduled regression suites
CoTester is best for QA leads and engineering teams at mid-size and large companies who want to expand automated coverage without writing every script by hand. A practical tip: during the free trial, connect a well-written set of Jira stories for one feature area first, so you can compare the generated tests against your current suite before rolling the agent out more widely.
