B2B SaaSFor: QA Engineers

Ensuring Compliance and Precision in Regulated Industries

For industries with stringent compliance requirements, achieving precise, scalable, and secure testing with traditional tools is a major challenge. CoTester provides domain-aware AI testing with enterprise-grade features like private cloud deployment and AI guardrails, ensuring both automation speed and the human control essential for regulatory adherence.

Financial ServicesFor: Enterprise Teams

Empowering Cross-Functional Teams for Collaborative Quality Assurance

Siloed test creation, where only highly technical users can contribute, often hinders agile team collaboration and slows down feedback loops. CoTester's no-code, low-code, and pro-code options enable Product Managers, Business Analysts, and Manual Testers to actively generate, manage, and execute test cases, fostering a unified approach to quality.

Enterprise SoftwareFor: Product Managers

Expediting Bug Detection and Debugging for Faster Releases

Manual bug identification and complex debugging processes frequently delay software releases and obscure critical issues, impacting delivery cadences. CoTester automatically detects, flags, and logs bugs during test runs, while its AI agent assists with real-time debugging and test logic adaptation, significantly accelerating the path to stable software.

Frequently asked questions

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.

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.

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.

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.

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.

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

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.

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.

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.

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.
