AI Playwright Execution
Bring your existing Playwright suite as-is. Harness runs it on cloud infrastructure inside your CI/CD pipeline, no migration required.
Playwright is the standard. But cloud execution, AI, and pipeline visibility each require a separate tool with no shared context.
Three tools. Three dashboards. No shared context.
One platform for execution, AI assertions, CI/CD gating, and test insights.
Execution grids don't know which commit, artifact, or environment triggered a test.
Harness tests run inside your pipeline. Full commit, artifact, and environment context built in.
UI changes break selectors. Flaky tests erode trust. More time fixing than shipping.
AI assertions adapt to UI changes automatically, no rewrites, no maintenance.
Keep every test you've already written. Harness layers AI intelligence on top, no rewrites, no migration, no risk.
No changes to your test code. No new infrastructure to manage. Just point Harness at your existing Playwright suite and go.
Point to a Git repo folder containing your Playwright tests. No configuration changes to your test code required.
Set your branch, runtime options, and browser targets: Chrome, Edge, Firefox. Tunnel support for firewalled environments.
Trigger from a Harness CI/CD pipeline or on-demand. Tests run in parallel across browser combinations on cloud infrastructure.
View results, logs, and AI-generated failure summaries in a unified dashboard. Every execution visible across your team.
Playwright runs are first-class pipeline steps, not bolted-on grid services. Fail fast, block bad deploys, and tie every result to a commit.

AI categorizes failures by root cause (regression, performance, or UI issue) so your team spends time fixing, not triaging.
BrowserStack and Sauce Labs run your tests. Harness runs your tests inside your pipeline, with the deployment context, AI intelligence, and unified visibility that execution-only tools can't provide.
Playwright tests run as steps inside Harness CI/CD pipelines, with the same YAML, RBAC, and audit trail as your deployments. Deployment gating with no custom scripting.
AI generates a natural-language summary of every failed test run. Instant root-cause identification and automatic categorization: product bug vs flaky test vs infra issue.
Enhance existing tests with natural language assertions. Instead of brittle selectors and exact string matching, AI understands intent and adapts to UI changes automatically.
Run hundreds of tests simultaneously across browser combinations with no infrastructure to manage. Enterprise-grade security and compliance built in.
A gradual, low-risk adoption path from running existing tests to AI-powered quality, at whatever pace works for your team.
Run
Bring existing Playwright suites to Harness Cloud with zero changes. Immediate visibility, centralized results, CI/CD gating.
Enhance
