What You Get With TestGrid as a Functionize Competitor
As your testing needs grow, you need a platform that can support more workflows without adding more tools to manage.
Real device testing
Test web and mobile applications on physical iOS and Android devices. Validate biometrics, GPS, camera input, gestures, image injection, and network conditions on real hardware and identify issues earlier.
On-premise and hybrid testing
Run TestGrid across private cloud, hosted dedicated, hybrid, or on-premises environments. Choose where your browsers and devices run based on security, data residency, and network requirements. It’s that simple on TestGrid.
CoTester AI
Create executable tests from requirements, user stories, and specifications with CoTester, TestGrid’s AI testing agent. Review generated steps and keep human approval at critical checkpoints.
Performance and load testing
Run JMeter-based performance and load tests for web, mobile, and API workflows. Track CPU, memory, battery, network activity, responsiveness, and other performance signals during testing.
Cross browser testing
Ensure web applications work reliably across browsers, versions, operating systems, and devices. Use secure connectivity for staging environments, private networks, and localhost applications.
Automated test maintenance
Spend less time fixing broken locators as self-healing capabilities help supported automation adjust to interface changes. Minimize repeated locator fixes across regression workflows as your application evolves.
Codeless and code-based automation
Automate workflows with scriptless authoring or Record & Play, or continue using Selenium, Appium, Cypress, and Playwright. Choose the approach that fits each project and your existing automation stack.
CI/CD and DevTools integrations
Connect TestGrid with Jenkins, GitHub Actions, GitLab, Azure DevOps, Jira, and TestRail. Trigger tests from your delivery pipelines and connect results with your existing development and QA workflows.
