Quickly and Effectively Testing Qt Desktop Applications

on YouTube ↗49m

" summary

Shows how to get tests into an untested Qt app fast by changing the build to produce a static library plus a test executable, using Catch2 with a QApplication main, and hiding widget fiddliness behind reusable fixtures. Demonstrates Qt helpers like QSignalSpy, recommends converting old string-based signals to pointer-to-member connections, and introduces ApprovalTests via ApprovalTests.cpp.Qt to verify widget state as TSV snapshots. Covers CI tips (-platform offscreen, guard tests when no display) and when to use Squish for full-app recording.
