Why Choose Puppeteer Testing Platform by TestMu AI (Formerly LambdaTest)
Run your existing Puppeteer scripts at scale on Chrome and Chromium with AI agents, HyperExecute, native browser protocols, and parallel execution, no infrastructure to maintain.
AI Agent Testing
Author Puppeteer Tests With AI Agents
Describe a scenario in natural language and let Kane AI author, run, and maintain your Puppeteer tests, so your suite stays in sync with application changes without manual scripting.
- Describe a scenario in natural language and let Kane AI generate the test.
- Import Jira tickets, PRDs, images, or sheets and turn them into structured test cases.
- Trigger AI-authored tests from the terminal or any CI/CD pipeline.
Faster Test Execution
Execute Puppeteer Suites 70% Faster With AI-Native HyperExecute
HyperExecute is an AI-native orchestration platform that executes your Puppeteer suites up to 70% faster than a conventional cloud grid.
- Auto-split the Puppeteer suite across runners so more tests run in parallel.
- Fail fast and halt the entire job the moment a critical test breaks.
- Rerun only failed tests while AI-driven root cause analysis pinpoints the failure.
Native Browser Protocols
Drive Puppeteer Tests With CDP and BiDi
Puppeteer is built on the Chrome DevTools Protocol and also supports WebDriver BiDi, so you can intercept requests, capture logs, and stream live browser events at scale.
Get Started For Free- Intercept requests, grab logs, and run performance traces over CDP in the cloud.
- Stream live browser events to your scripts with WebDriver BiDi support.
- Debug faster with network HAR logs, console logs, and full session telemetry.
Parallel Test Execution
Scale Puppeteer Tests in Parallel
Run automated Puppeteer tests concurrently across browser and OS configurations and reduce your overall test execution time by multiple folds.
Get Started For Free- Scale concurrent Puppeteer sessions on demand with no infrastructure to provision.
- Run your full suite on every pull request without blocking merges.
- Offload browser infrastructure to a fully managed, autoscaling cloud.
Seamless Integration
Integrate Puppeteer Tests Into Your CI/CD Pipeline
Connect TestMu AI (formerly LambdaTest) to your CI/CD pipeline and run Puppeteer tests on every commit without reworking your workflow.
Get Started For Free- Install pre-built plugins for Jenkins, GitHub Actions, and GitLab with automated result parsing.
- Trigger Puppeteer runs on every commit and gate pull request merges on pass/fail status.
- View execution logs, build summaries, and failure reports directly inside your CI/CD dashboard.
