## What the story says

Bubble, a no-code app builder, works with QA Wolf to build end-to-end test coverage for its platform. This lets its small engineering team catch regressions without taking developers off feature work or hiring QA engineers.

Summary written by usedby from the source page, in English. The figures are those of QA Wolf and Bubble, not ours.

> Between QA Wolf’s test suite, and the automated tests that Bubble had previously built out, the team reached nearly 100% test coverage in four months. With that coverage, Bubble could ship faster and with higher confidence that the changes would add value and not break existing functionality.

- **1,400**: “1,400 automated tests kept Bubble from popping”

> We were able to focus on building, hiring, and hitting the goals we set for ourselves. Honestly, you were one of the smoothest vendors we’ve ever worked with.

> Allen Yang, VP Product
