Unparalleled execution

Every test starts at the same time in its own browser. No queues, no shards, no waiting for a free runner.Read more

  • 34M+web tests a year
  • 22 yearsof browser time, every month
  • <1 sectest start time

One web suite of 300 tests, each one to five minutes long. QA Wolf starts every test at the same time, each in its own browser, so they finish one after another and the suite is done when the longest is, in 5 minutes. Done yourself on a grid of 10 parallel runners, each running one test at a time, it takes 1 hour and 33 minutes.

Clean containers for every run

Every test, and every retry, runs in a fresh container with a new browser. If one hangs, the rest of the suite keeps going. Nothing carries over between runs, so a failure points to your app, not the last test.

An exploded view of a test container: the container, and above it a layer for each thing a run can leave behind in a browser: downloads, service workers, the cache, local storage, cookies, and the browser itself. Between runs the layers spread apart, each is cleared, the browser is replaced with a new one, and they close up again, so the next run starts clean.

Headed browsers test real-world conditions

QA Wolf renders your app exactly like a user would see it, so you can build coverage for real-world conditions, catch visual regressions, and have a recording of every run.

  • Chrome
  • Firefox
  • WebKit
  • Electron

On QA Wolf, a headed browser with a video site open: a video of the sea at night playing on the left, with its title and channel under it, a playlist on the right, an ad blocker extension open, and the run recording.

Infrastructure for complex tests

Build and run end-to-end tests that a CI runner or a browser grid can't. Seed data through your API, read real emails and texts, and control every part of the browser, all from your test code.

  • Seeded accounts

    Call your API to give each test an account with exactly the data it needs.

  • Electron apps

    Launch your Electron app and test its windows, menus, and main process.

  • Sign-up emails

    Sign up with a real email inbox, then open the confirmation link inside.

  • Texted codes & MFA

    Sign in with codes texted to real phone numbers, or with MFA and passkeys.

  • Back-end checks

    Call your API after a step to check the change saved, not just showed.

  • Third-party apps

    Check that your app and tools like HubSpot, Shopify, and Slack stay in sync.

  • Pop-ups & OAuth

    Sign in through pop-up windows and OAuth providers, the way users do.

  • Checkout & 3-D Secure

    Check out with saved cards, gift cards, and wallets, and pass the bank's 3-D Secure check.

  • Iframes

    Type into payment forms and widgets embedded from other sites.

  • Uploads & downloads

    Upload a PDF and extract its content, or export a CSV and check the data inside.

  • Network mocking

    Mock API responses and errors to test every state of the page.

  • Visual regression

    Compare key screens to an approved baseline and catch layout shifts and broken styles.

  • Password managers & wallets

    Install extensions like password managers and wallets, which headless browsers can't load.

  • Location & permissions

    Set the browser's location, then allow or block its prompts.

  • Clock & time zones

    Fast-forward the clock to test countdowns, expiry, and time zones.

  • Canvas & drag and drop

    Draw, drag, and drop, then check where everything landed.

  • Clipboard

    Copy and paste, then check exactly what's on the clipboard.

  • Accessibility

    Scan for WCAG and Section 508 compliance and keep an audit log for every release.

Run Rules orchestrate users and data

Modern apps collaborate with multiple users on different devices. With QA Wolf's multi-platform infrastructure you can test an integrated experience, not just separate steps.Read more

One test across two users and three screens. Sam, a shopper, looks at a shirt and orders it; the button confirms the order, and a second tab opens on the order's details. Alex, the store's admin, signed in as a different user in another browser, sees the new order in the queue and ships it, and Sam's order shows it shipped. Then Sam's iPhone gets the shipping notification. The test passes.

Test artifacts show devs exactly what broke

Every run keeps its video, Playwright trace, console, and network requests on one timeline, so you can see why a test failed without running it again.

The bug report QA Wolf filed when a loan application test failed: the credit check times out after uploading pay stubs. It carries the run's video, trace, code and logs. Its recording plays the run, from signing in with a texted code, through the income and two pay stubs uploaded, to the credit check failing at 0:40, which is marked on the seek bar. Under it, the test's six steps: the first three passed, the credit check failed, and e-signing the offer and getting the confirmation email didn't run.

The test infrastructure you'd otherwise build

Running a big suite yourself means clusters across regions, artifact storage, monitoring, retries, cleanup, and engineers to keep it all running. QA Wolf has built all of it, and it's included.

What a team needs to run its own end-to-end tests at scale: clusters across regions, so every test can run at once, artifact storage, monitoring and alerts, security and patching, run order and limits, retries for flaky tests, data cleanup, and engineers to run it. All of it is included on QA Wolf.
