Challenge

A high-output team that needed QA in lockstep

Scope3 was building a customer-facing dashboard for emissions data, which had previously been accessible only through their API. They needed end-to-end testing to protect product quality and maintain customer trust. 

“Anytime you want to merge a change, you’d have to manually QA like a hundred different things to feel really confident.”
—Kelsey Leftwich, former Lead Engineer at Scope3

Manual QA was slowing development and pulling teams away from their core work. The team could either hire multiple full-time QA engineers or risk shipping without a safety net.

“You set up this great system and then a week in, tests are breaking. No one wants to maintain the tests, and eventually you just sort of forget about it.”
—Kelsey Leftwich, former Lead Engineer at Scope3

Scope3 needed a QA partner who could embed directly into their workflow, learn the team and product inside and out, and adapt on the fly without losing context—a true extension of the Scope3 team. Because they move fast and ship often, Scope3’s QA process had to operate in sync with development. That meant more than just running and maintaining tests—it meant working closely with product and design to catch issues early and keep coverage current, no matter how fast the roadmap moved.

“Our CTO set up this relationship with QA Wolf when he realized that somebody embedded from QA Wolf would increase our confidence in shipping new things in our ecosystem.”
—Emil Sit, VP of Engineering at Scope3
Results

The payoff of dedicated QA expertise: high coverage, higher confidence

24 hours to get automated tests for every new feature

Instead of hiring a full-time QA manager, QA Wolf assigned Marri Kang to be their dedicated QA Wolf engineer and work exclusively with their team. She joins project kickoffs, knows the product like an in-house QA lead, and drives more strategic test coverage. The team relies on her for everything from test automation to product feedback, and treats her as the go-to for any QA challenge. 

“Marri has an excellent sense for what needs testing and often spots potential issues before I do. We work closely together to keep our product quality high, and she's caught many bugs that could have otherwise slipped through to production.”
—Nastassia Fulconis, Senior Software Engineer at Scope3

Deploying more than 20 times per week

Today, QA is built into Scope3’s development process from the first line of code. For every new feature, Marri is looped in at the ideation stage—tagged on PRs, reviewing acceptance criteria, and writing tests alongside development. Features launch with full coverage already in place, so the team maintains momentum instead of slowing down to catch up on QA after release. 

“Creating new product features is so much easier when you know your quality is protected. We high-five after every launch and jump right into the next idea with no fear of regressions because our coverage keeps us safe.”
—Lucas Bassetti, Senior Software Engineer at Scope3

90% automated test coverage 

233 tests span everything from account creation and login to magic link delivery, report viewing, and data integration setup. New tests are easy to add: Scope3 can share a Loom walkthrough, and QA Wolf turns it into automated coverage that runs with every deploy. 

“With QA Wolf, most of our app is fully covered by automated tests. We can build faster, with the confidence that if something breaks, we’ll know right away. It keeps our velocity high and removes the mental drag of wondering, ‘what if I broke something and didn’t realize?’”
—Lucas Bassetti, Senior Software Engineer at Scope3

Fully integrated into Scope 3’s continuous delivery pipeline

With QA Wolf’s tests integrated into the CI/CD pipeline, Scope3 can merge to production multiple times a day. Tests find bugs before customers see them, so engineers can build features instead of grinding on manual QA. 

“Without QA Wolf, our deployment process would be significantly more stressful and time-consuming. The confidence we have when pushing to production is invaluable—QA Wolf's end-to-end tests mirror real user journeys so closely that we can deploy knowing our customers will have a seamless experience.”
—Nastassia Fulconis, Senior Software Engineer at Scope3
