CoTester is the world’s first purpose-built AI software testing agent that autonomously creates, runs, and self-heals automated test cases for enterprise applications. Unlike traditional tools, it understands application context from project specs or URLs, generates executable test scripts within minutes, and adapts automatically to UI changes during execution.

Who is CoTester intended for?

It is designed for QA engineers, automation beginners, product owners, and enterprise teams in industries like banking and healthcare that require precise, secure, and scalable software testing. It enables users of all skill levels to contribute to test automation.

How does CoTester work?

CoTester connects with project management tools like JIRA to link requirements or stories. It uses AI to learn application workflows and domain context from documents such as PDF, Word, and CSV, as well as URLs or specs. It rapidly generates maintainable test scripts in scriptless, record-play, or code-based modes, with options for human-in-the-loop review. It executes tests on real browsers and devices with live logs, screenshots, and debug support. Furthermore, it employs a self-healing engine (AgentRx) to automatically update tests in real time in response to UI or workflow changes.

What are the key features?

CoTester offers multiple authoring modes, including scriptless, record-and-play, and code-based creation. It provides natural training on documents and URLs for tailored AI understanding. Its AgentRx self-healing capability minimizes maintenance by adapting tests during runtime. It also features AI guardrails and checkpoints for human validation in critical steps, along with full code ownership so teams retain control of test scripts and logic. Additionally, it includes integration with CI/CD, secure data handling, and deployment flexibility, offering both cloud and on-premise options.

What types of testing does CoTester support?

CoTester supports web, mobile, API, and IoT testing across real devices and browsers via TestGrid’s cloud infrastructure. Scheduled test executions enable alignment with delivery cycles like nightly builds or release regressions.

Can CoTester identify and log bugs?

Yes, CoTester automatically detects bugs during test runs, flags them, and logs issues for immediate team visibility without extra manual work.

How do users interact with CoTester?

CoTester offers a conversational, chat-style interface that understands natural language without strict syntax rules, making it easy for technical and non-technical team members to work with. It provides detailed explanations of generated test steps and supports editing directly via chat or code editor with syntax highlighting.

How to get started with CoTester?

To get started with CoTester, users should sign up on TestGrid’s platform and access CoTester through their dashboard. They can train it by uploading documentation, linking project stories, or providing URLs. Users then review and modify generated tests before execution. Finally, they can run tests on real devices/browsers and monitor detailed reports, which include screenshots and logs.

What sets CoTester apart from traditional testing tools?

Unlike legacy script-based or record-playback tools, CoTester understands your product domain, generates tests automatically, adapts dynamically to UI changes, and involves humans only where necessary for approvals. It combines robotic execution precision with AI-driven creative test design to reduce testing time by up to 50% and lower maintenance efforts.

What are the pricing and availability details for CoTester?

Details on pricing are available on the TestGrid website, with deployment options for private cloud or on-premises environments tailored to enterprise security and scalability requirements.
