The decision
Should CoTester make your shortlist?
Start with the job, the team, and the constraints. Product fit becomes much clearer when those three line up.
Practical use cases
Jobs it can take on
- Generate test logic from Jira stories, specifications, or a test description
- Run and debug tests on real browsers and mobile devices
- Schedule regression tests and receive logs and screenshots from execution
Before you choose
Know the tradeoffs
- The Starter package includes 5,000 tokens for AI test creation.
- CoTester creates tests in Selenium Java or Appium Java.
- TestGrid's trial is a guided proof of concept rather than a self-serve trial.
Inside the product
What you can actually do with it.
The core product capabilities, grouped around the work they enable.
Context-aware test creation
CoTester turns linked Jira stories and uploaded specifications into test logic while learning product context and QA workflows.
AgentRx self-healing
AgentRx detects UI changes during execution and updates test logic to adapt to structural changes and redesigns.
Guarded execution
CoTester pauses at critical checkpoints for team validation and supports manual editing in scriptless, record-and-play, or code modes.
Typical workflow
Provide documentation, a URL, a description, or linked Jira stories to create test cases. Refine generated steps in the chat interface or editor, then approve execution on real browsers and devices. CoTester returns execution logs and screenshots while identifying and logging bugs.
