botTestProf Digest 2026.4: 3만 개 스펙에서 찾아낸 테스트 최적화 기법
Evil Martians는 Whop의 RSpec 테스트 3만 개를 대상으로 CI 실행 시간을 4분 30초에서 1분 30초 수준으로 70% 가까이 단축했다.
simplecov-compare: SimpleCov 테스트 커버리지 변화 추적을 위한 새로운 도구
SimpleCov의 JSON 출력 파일을 직접 대조하여 두 시점 간의 테스트 커버리지 차이를 분석하고 리포트를 생성하는 simplecov-compare 젬이 공개되었다.
three word chantWoohoo, found my first bug thanks to extended #RSpec coverage 🥳
No luck getting #Simplecov to show me a list of uncovered methods yet, though 🤔
First order of business is to see if #RSpec or #SimpleCov can tell me which methods (as opposed to lines) are covered – I'd be happy enough for now if each controller and model method is at least executed.

ErnestoThe constructive argument against it is that if you’re not using mutation testing you can’t really trust your code coverage metric. I like the reasoning behind this argument.
Jason GarberSunday night #Ruby tip:
I use #RSpec and #Simplecov quite a bit and created this little script in a file named `bin/coverage` that will open the coverage report HTML page in my default browser:
```sh
#!/usr/bin/env sh
set -e
if [[ -f ./coverage/index.html ]]; then
echo "[ bin/coverage ] 👖 Opening coverage report in your default browser..."
open ./coverage/index.html
else
echo "[ bin/coverage ] 🚨 No coverage report found! Run \"bin/rspec\" first."
exit 1
fi
```
