With and without Pie
Three Days by Hand. A Few Hours With Pie.
Re-checking what already works eats your week. Hand the regression pass to Pie and your team builds instead. Slide the numbers to see what that’s worth.

When it runs
Nobody Has to Start It. You Pick What Starts It.
Set it once and regression comes off the calendar. Run it after hours and your team starts the day with the results.
-
On Your Schedule
Nightly, on weekdays or weekly, at the time you pick.
-
When Your CI Calls
Your CI or deploy script fires an API trigger, and the suite runs after the deploy.
-
When a New Build Lands
A new iOS or Android build starts the suite, once we’ve set this trigger up with you.
Pie Runs Every Test
Nobody has to watch it.
A sample run
The Report Is Waiting
37 passed3 failed1 issue
What broke, with the steps and a screenshot of each.
What comes back
Not a Red X. A Bug You Can Hand Over.
Pie writes up every failure, steps and screenshots included. Your developer starts on the fix, not the repro. This one is real. Pie caught it in Pie.
- You make the call.Track it and Pie re-checks it on every run, or dismiss it.
- No back-and-forth.It says what should have happened and what did, in plain words.
- Proof at every step.Each step keeps its screenshot. The failed ones show in red.
Your suite, your call
You Can Read Every Test. Your Team Decides What Runs.
Always know what’s running. Pie drafts your regression suite in plain English, from your description or by exploring your app, and your team confirms every test.
- Plain English, no code.Anyone on your team can read a test and check it.
- Wrong? Tell Pie.It fixes the test in your draft. Nothing changes until you save.
The basics
New to Regression Testing? Start Here.
Get up to speed in eight short answers, from what it is to how to automate it. The guides go deeper.
Regression testing re-checks what already worked after every change, because a change can break code it never touched. A checkout fix can break the password reset.
By hand, someone clicks through the same flows before each release. Automated, a suite runs on a schedule or a trigger and reports what broke.
Our guide to regression testing covers the types and when each one fits.
A shopper resets a password from the email link. It worked last release. After the next one, the link opens a blank page.
A regression test replays that flow whenever the suite runs and fails at the step where the page loads blank, so your team finds out before your shoppers do.
Smoke testing asks whether a new build works at all. Pull request testing asks whether one change broke something, before it merges. Regression testing asks whether everything that used to work still does, and it runs nightly or before a release.
Pie runs all three.
Start with what costs you most when it breaks, usually sign-in, checkout and payments. Add every bug you’ve already shipped once, so it can’t come back unnoticed.
A single test can walk a whole journey from sign-in to checkout, which is end-to-end testing.
Then cut the tests that repeat each other. A suite nobody can finish running protects nothing. Here’s how to build a regression test suite, step by step.
Nightly if you ship often, and at least before every release. Some teams run a small suite on weekdays and the full pass once a week, and Pie can schedule each on its own.
The repeat checks can. Choosing what goes in the suite and deciding what a failure means stay with your team.
By hand there’s no setup, but a pass costs days. Playwright and Cypress are free and exact, but someone has to keep the scripts working every time the UI moves. An agent like Pie runs tests written in plain English, with no locators to break.
Because a red run stops meaning a bug. Flaky tests fail for no clear reason, test data goes stale, and soon nobody reads the failures.
Trust comes back when every failure shows its evidence and only counts as a bug once it’s confirmed. Pie keeps every test’s steps and screenshots, and you make the final call on what counts as a bug.
You’re testing two platforms, more builds and screens that differ by device. Each platform can have its own suite, and a run starts from a build instead of a URL.
Pie tests iOS apps on the iOS Simulator (a simulator .app build) and Android apps on the Android Emulator (an .apk).
Our guide to mobile app regression testing covers how to split them.
Customers
Teams That Moved It Off the Calendar.
“As we scale our products and offerings it’s really important to make sure we don’t ship something that breaks the existing experience for our users.”
“After evaluating multiple vendors, Pie was the only solution that consistently executed our most complex end‑to‑end workflows with reliability across builds.”
Security
Yes, Security Will Ask. Here’s What to Tell Them.
- You Pick the Test Account.Pie signs in with the test login you give it. A setup script can call your test API to create the data first.
- We Never Use Your Source Code to Train AI Models.Source code here means the files and code changes in your repositories.
- Logins Reach Pie’s Agents Only While a Test Runs.You keep them in Pie’s credential settings.
- Pie Has a SOC 2 Type 2 Report.Our most recent report is available on request. Data is encrypted in transit.
