AI Playwright Execution

Bring your Playwright tests. We handle the infra and AI.

Bring your existing Playwright suite as-is. Harness runs it on cloud infrastructure inside your CI/CD pipeline, no migration required.

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 adapt to UI changes automatically, no rewrites, no maintenance.

What you get

Bring your Playwright scripts. Enhance with AI.

Keep every test you've already written. Harness layers AI intelligence on top, 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. Tunnel support for firewalled environments.

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 → AI Test Automation

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 triaging.

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 failure triaging

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 understands intent and adapts to UI changes automatically.

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.
