Playwright Execution

Run Playwright tests as part of your CI workflows.

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.

The challenge

Don't choose between Playwright and AI testing.

Playwright is the standard. But cloud execution, AI, and pipeline visibility each require a separate tool with no shared context.

Fragmented stack

Three tools. Three dashboards. No shared context.

One platform for execution, AI assertions, CI/CD gating, and test insights.

No deployment context

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.

Brittle at scale

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.

What you get

Bring your Playwright scripts. Enhance with AI.

Keep every test you've already written. Harness executes them as CI pipeline steps, no rewrites, no migration, no risk.

How it works

Up and running in four steps.

No changes to your test code. No new infrastructure to manage. Just point Harness at your existing Playwright suite and go.

01

Create

Point to a Git repo folder containing your Playwright tests. No configuration changes to your test code required.

02

Configure

Set your branch, runtime options, and browser targets: Chrome, Edge, Firefox. Runs wherever your Harness CI environment does.

03

Execute

Trigger from a Harness CI/CD pipeline or on-demand. Tests run in parallel across browser combinations on cloud infrastructure.

04

Review

View results, logs, and AI-generated failure summaries in a unified dashboard. Every execution visible across your team.

CI/CD integration

Tests as a quality gate.

Playwright runs are first-class pipeline steps, not bolted-on grid services. Fail fast, block bad deploys, and tie every result to a commit.

How to add to your pipeline

1

Open any CI or CD stage

2

Add step → Playwright Execution

3

Set framework: Playwright

4

Select build config + environment

5

Configure timeout, retries, workers

AI analysis

Every failure explained, not just reported.

AI categorizes failures by root cause (regression, performance, or UI issue) so your team spends time fixing, not investigating.

Why Harness

Not just a test grid. A delivery platform.

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.

Pipeline-native execution

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-assisted debugging

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.

AI assertions via Harness SDK

Enhance existing tests with natural language assertions. Instead of brittle selectors and exact string matching, AI validates intent.

Cloud-scale parallel execution

Run hundreds of tests simultaneously across browser combinations with no infrastructure to manage. Enterprise-grade security and compliance built in.

Your path forward

Flexibility tailored to your preferences.

A gradual, low-risk adoption path from running existing tests to AI-powered quality, at whatever pace works for your team.

Start here

Run

Stable tests as-is

Bring existing Playwright suites in as-is, running wherever your CI workloads execute. Immediate visibility, centralized results, CI/CD gating.

Recommended

Enhance

Add AI assertions

Augment flaky or brittle tests with Harness SDK AI assertions. Natural language validation of intent, instead of exact selector matching.

Full pipeline coverage

Expand

Gate every stage

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.
