## What the story says

Stack Overflow's engineering team uses mabl to automate testing of its Teams (private Stack Overflow) product, which had previously relied on manual testing. They build reusable test flows, run mabl tests as part of their CI/CD and engineering workflows, and plan to extend use to product teams and other parts of the platform.

Summary written by usedby from the source page, in English. The figures are those of mabl and Stack Overflow, not ours.

> The Stack Overflow team had been relying on manual testing for the Teams product for some time but realized they could do a much more effective job by bringing in test automation.

> So mabl obviously, came to the top of the list very easily.
