CoTester

AI agent teammate for end-to-end software testing

CoTester is an AI agent embedded in the TestGrid platform that acts as an always-available teammate for software testing. It’s designed for QA and development teams to modernize and automate testing across web and mobile, using TestGrid’s real-device and browser infrastructure. You use it alongside TestGrid’s codeless, scripted, and manual testing workflows to speed up test generation and execution.

About

What It Is

CoTester is an AI agent for software testing built into TestGrid, a unified test infrastructure and automation platform. It targets QA engineers, software developers, and enterprise testing teams that need to modernize their testing approach and consolidate tools. The product positions itself as an "always-available AI teammate for testing," pre-trained on software testing fundamentals, architecture, and tools.

You access CoTester through the web-based TestGrid platform, which provides codeless testing, scripted automation (Selenium, Appium, Cypress, and more), and manual testing on real iOS/Android devices and browsers. TestGrid offers flexible deployment options—on-premise, private dedicated cloud, and hybrid setups—plus 100+ integrations, so CoTester sits on top of an existing, full-stack test infrastructure rather than acting as a standalone chatbot.

What to Know

According to the site, CoTester is described as an AI agent and testing "teammate," but the publicly visible material gives limited specifics on exactly how autonomous it is—such as how far it goes in automatically generating, maintaining, and executing tests without human input. The broader TestGrid platform clearly supports end-to-end workflows from test generation to execution on real devices and browsers, but how much of that flow CoTester can drive on its own is not fully documented in the available content.

From an implementation standpoint, CoTester will be most useful if you’re already investing in structured QA processes and can plug it into TestGrid’s automation, codeless, and manual testing capabilities. Teams that require strict data residency or security controls may benefit from TestGrid’s on-premise and private hosting options, though specific model details, data retention policies, and privacy guarantees for the AI component are not provided in the snippet. If you’re looking for a simple, general-purpose AI assistant or a standalone testing bot without a broader platform, this likely isn’t the right fit. Pricing details are not clearly disclosed beyond a "Start for free" option and sales-led plans, so you’ll probably need to talk to their team for concrete costs and limits.

Key Features
AI agent purpose-built for software testing, positioned as an always-available testing teammate
Pre-trained on software testing fundamentals, software architecture, and common testing tools (according to the vendor)
Embedded directly into the TestGrid unified testing platform rather than operating as a standalone bot
Works alongside TestGrid’s web-based codeless testing IDE, including record-and-play and low-code/no-code authoring workflows
Operates on top of TestGrid’s execution layer for running automated tests on real mobile devices and desktop browsers
Use Cases
Augmenting QA teams with an AI agent that helps design and refine test coverage on top of TestGrid’s automation and device lab
Supporting development teams that already use Selenium, Appium, or Cypress by layering an AI testing assistant over existing scripted tests
Accelerating modernization initiatives where enterprises move from fragmented testing tools to a unified platform plus AI agent for web and mobile testing

Handles multi-step tasks with guidance

CoTester is an AI testing agent embedded in the TestGrid platform that helps generate tests and support end-to-end testing workflows on real devices and browsers. It has moderate action capability within the constrained domain of software testing and some autonomy in how it assists with test creation and execution, but there is no clear evidence of fully autonomous multi-step planning, robust adaptation, or persistent memory. Safety and control are mainly provided by TestGrid’s deployment and infrastructure options rather than explicit agent guardrails. Overall, this looks like a capable, domain-specific assistant integrated into a testing platform rather than a highly autonomous, self-directed agent.
