# Devin cloud testing of PRs

Devin writes a test plan, runs the app on a cloud VM with computer use, and returns annotated test videos and reports.

Result: Test runs approved per day on Devin more than doubled in a couple of months, and engineers run 10 to 20 Devins in parallel.

## How it was set up

Devin's computer use tools on a cloud VM, a code-grounded test plan, login scripts saved as repo testing skills, and a YAML blueprint snapshot.

## Worth knowing

Timing issues can miss transient UI like toasts, and models sometimes run JavaScript instead of clicking through the UI. First setup often needs credentials.

## Evidence note

Vendor's own account with GIFs; no independent customer named
