I had to save the exit code from one part of the script that runs a suite of tests, then run some cleanup and finally return the exit code received previously from the tests.
I haven’t used bash scripts too often in my work so when I had to do this recently I had to spend some time looking up syntax.
This will fail the tests correctly in our Azure Devops pipeline while still cleaning up the docker containers.
The script
The part I found difficult here was the escaping. Sometimes you need double quotes and other times it’s just the variable. This is a reference in case I ever have to do this again!
Note that to run this you will have to give it permissions chmod 755 myscript.sh
#!/bin/bash
main (){
docker-compose run node
exitCode=$?
echo "exitCode will be $exitCode"
}
setup(){
yarn
docker-compose up -d chromedriver
docker ps -a
}
tearDown(){
docker-compose down
docker system prune -f
}
setup
main
tearDown
exit "$exitCode"
