Question

Is there a way to automatically run tests, when a file in the app is changed? In rails there is a gem called guard. How can one achieve the same in nodejs?

Answer 1

Try this

touch /tmp/nt; while [ true ]; do if [ find . -newer /tmp/nt -type f
| grep -v app/cache | wc -l -gt 0 ]; then phpunit; touch /tmp/nt; fi;
sleep 5; done

I’m using it to autostart phpunit. Replace phpunit with the command to run tests
replace sleep 5 with sleep 1 if you wish to check every second (depends on the size of your files)
