CoTester

Paid

CoTester is an AI agent built for software testing work. You describe what you want tested. It writes and runs the tests for you.

CoTester sits inside TestGrid's platform. It generates test scripts from prompts, runs them on real browsers and mobile devices, and tries to fix itself when your app changes.

You can work without code, with some code, or drop into a full IDE. The tool pauses at checkpoints so you can check its work before it keeps going.

It is best for teams already using TestGrid or willing to buy that ecosystem. It is not a standalone tool you can grab and try today.

Open it if you need AI test generation and you already use TestGrid. Skip it if you want a standalone tool with clear pricing and a free trial.

It fits these situations better than most alternatives.

• Teams wanting AI-assisted testing across multiple frameworks: You get one interface for Selenium, Appium, Cypress, and Robot. You are not locked into one stack.
• Organizations needing real device testing for mobile: You test on actual phones and tablets, not emulators. This catches device-specific bugs.
• Mixed teams of manual testers and developers: Non-coders can write tests in plain language. Developers can edit the scripts when needed.
• QA teams already using or considering TestGrid's platform: You add AI without switching vendors. The learning curve is smaller.
• Organizations with limited coding experience: You describe tests in sentences. The tool translates to actual test steps.
• QA teams wanting to reduce manual scripting: You spend less time writing boilerplate. You still review and adjust.
• Teams seeking cross-browser and mobile test automation: One setup covers desktop browsers and mobile devices.
• Enterprises needing deployment control: You can run cloud, on-premise, or hybrid. This matters for regulated industries.

These are the parts that stick after you use it.

• Natural language test generation: You type what you want tested. It builds the script. You skip the blank page problem.
• Self-healing via AgentRx: When your UI changes, it spots the shift and updates the test. You spend less time fixing broken scripts.
• Real device cloud access: You test on actual hardware. Results match what users see.
• Human checkpoints: It stops for your approval at key moments. You keep control over what ships.
• Flexible code modes: You start no-code, move to low-code, then switch to full IDE when you need it. You grow without switching tools.

The flow is straightforward if you are already in TestGrid.

1. Connect your repository and CI/CD pipeline.
2. Feed it user stories, specs, or existing test cases for context.
3. Prompt it in natural language to generate new tests.
4. Review the generated script before it runs.
5. Execute on real devices or browsers, with checkpoints for your approval.

These limits matter for some teams.

• No clear pricing: You cannot see costs without talking to sales. Budgeting is hard.
• Locked to TestGrid: You cannot use it without their platform. Switching later means starting over.
• Unverified speed claims: Promises of 40-70% savings lack independent proof. Your mileage may vary.
• Struggles with dynamic elements: Simple UI flows work well. Complex, shifting interfaces need more manual help.
• Mid-market pricing squeeze: Enterprise accounts get flexibility. Smaller teams report feeling stuck between tiers.
