CoTester

What is CoTester?

CoTester is TestGrid's enterprise-grade AI software testing agent built for enterprise teams that can't afford flaky test scripts or constant maintenance overhead. Designed for industries where precision, scalability, and compliance are critical, it autonomously converts product requirements or JIRA stories into executable, intelligent test logic—then validates its direction with your team before execution.

The tool works in three flexible modes: **no-code** (or scriptless automation) for product managers and business analysts, **low-code** for manual testers who prefer visual steps or record-and-play setups, and **pro-code** for automation engineers who need to write custom scripts. That flexibility matters because most enterprise teams have people at different skill levels touching the same test suite, and they can switch between these modes without losing context.

What’s interesting is **AgentRx, the self-healing engine**. It uses a Vision Language Model to interpret your app’s UI like a human tester would. When UI changes happen during execution, it adjusts test logic on the fly instead of failing the entire run. This is a departure from traditional tools that rely on brittle locators. The engine is designed to adapt to both minor locator changes and large-scale structural UI redesigns in real time, addressing a genuine pain point for teams dealing with complex, high-traffic apps.

CoTester pauses at critical checkpoints to validate its direction with your team. It won’t execute anything without approval, providing human-in-the-loop guardrails enterprises care about. You can manually edit test steps anytime, insert custom hooks, and parameterize test data from internal databases with encrypted secrets. That level of control matters when you’re testing banking apps or healthcare platforms where compliance isn’t optional.

The tool schedules test runs for nightly builds, weekly regressions, or pre-release checks. It flags bugs automatically during execution and logs them in real time. It integrates seamlessly with Jenkins, GitHub Actions, Azure DevOps, and other CI/CD pipelines, supporting Git-based collaboration. By combining **AI-driven creativity in test design with rule-based robotic execution**, it frees teams to focus on building software, not fixing tests.

Who this is for: QA engineers tired of babysitting tests, automation engineers drowning in maintenance work, and agile teams where product managers need visibility into test coverage. It’s being used in banking (BFSI), eCommerce, telecom, healthcare, and travel, and is already trusted by Fortune 100 companies where precision and compliance are non-negotiable.
