Playwright Execution
Bring the Playwright suite you already have. Harness executes it as part of your builds, so testing runs alongside build and deploy instead of in a separate service.
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 validate intent instead of exact selectors, reducing false failures from minor UI changes.
Keep every test you've already written. Harness executes them as CI pipeline steps, 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. Runs wherever your Harness CI environment does.
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 investigating.
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 validates intent.
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 in as-is, running wherever your CI workloads execute. Immediate visibility, centralized results, CI/CD gating.
Enhance
Augment flaky or brittle tests with Harness SDK AI assertions. Natural language validation of intent, instead of exact selector matching.
Expand
Run your Playwright suite as a quality gate across every CI and CD stage, with AI-assisted debugging giving every team instant root-cause visibility.
Run your existing Playwright suite through Harness CI. No changes to your test code required.
