Customer story

At AllTrails, automated testing enhances collaboration between engineering and QA

AllTrails is an outdoor application that helps users find and navigate hiking, mountain biking, and running trails, with photos and reviews curated by millions of users across the world. Because adventurers rely on AllTrails for navigation, it was critical to get as close to bug-free as possible. Unfortunately, James Graham, CTO, and Adam Blumberg, QA Manager, found that these updates were taking weeks to build and test.

To make their QA process more efficient and free from human error, Graham and Blumberg partnered with Waldo. By taking advantage of Waldo’s end-to-end test automation, AllTrails has streamlined its mobile testing process. The QA and engineering teams can now communicate and fix issues in real time, allowing them to ship quickly and expand their offerings to include three additional languages. Thanks to Waldo, AllTrails ships updates with the peace of mind that errors that are hard for a human to find have been caught, giving the user a safe and seamless experience. 






Tests Run


Hours Saved

While an engineer is still in the same headspace of writing a feature, if they see a bug in the code that they've written, they're able to immediately fix that before it even gets to our manual QA team.

The Challenge

Manual testing creates a heavy workload for a lean workforce

AllTrails, a mobile app for outdoor recreation, had a nuanced strategy for testing updates before they shipped. “Before every release, we would rely on other cross functional teams to run a regression suite on the app,” said James Graham, CTO of AllTrails. ”This could take anywhere from three to four days.” 

But the company was growing quickly and needed to ship more often and at a regular cadence. Taking cross functional teams away from their primary work to manually test was not scalable.

“We wanted to ship much more quickly than we’d been shipping in the past,” said Adam Blumberg, QA Manager at AllTrails. “We didn’t want to wait two, three, four weeks to get things out the door.”

The Solution

QA team codes its own tests and triages with engineers in real time

Graham and Blumberg set out to find automated end-to-end testing for their mobile app. They knew they didn’t want the technical debt that came with engineers having to work on scripts, so they chose to partner with Waldo. 

Waldo’s user-friendly interface removed the burden of having to write and maintain scripts from the engineering team—the QA team can now create tests themselves. “Waldo’s interface makes it really easy for our QA team to edit, test, and modify each test,” Graham said. “It's a more seamless experience than managing and maintaining scripts.”

“Waldo is great for allowing people who aren't software engineers to jump right in and code a test quickly,” Blumberg added.

Now, instead of pulling people away from customer support for manual testing, the QA team can run a test suite on its PR process and code cycle nightly. These tests include login, signup, navigating to a trail page, and looking at a map—critical paths that cannot be broken. Engineers immediately receive the results from the tests QA ran and are able to resolve any issues Waldo may have found. 

By taking advantage of the ‘Rules’ feature in Waldo, the QA team can also implement a smaller subset of tests while the engineers run through them simultaneously. “That means the engineers are able to work on the issues before they reach the manual QA team—as opposed to being notified later, when the engineer has moved on to something else,” Blumberg said. “Once you've moved on, it's hard to put yourself back in the headspace of that code, and the bug doesn't immediately get fixed.”

The Result

With Waldo’s seal of approval, issues don’t fall through the cracks

About 60% of AllTrails’s QA on the app is now covered by Waldo. That’s time that goes back to the QA team to spend on ad hoc testing and working on the next release cycle. The QA team can work with confidence knowing that Waldo will find bugs they didn't catch in manual tests. 

“We know that Waldo will run a regression suite every day and find any bugs or gaps in the UI that may change from the previous version of the app,” Graham said. “The customer experience is what we're validating.”

By taking time off the manual QA team’s plate and allowing engineers to respond to issues in real time, AllTrails has gained the velocity it needs to ship the app on time.

“It gives everybody high confidence when we have that Waldo seal of approval,” Blumberg said.


We're able to ship a lot quicker in our release cycle. The amount of coverage that we have on the mobile app, it allows us to take those cases off of our manual team's plate.
