grep result of npm test in bash conditional

I need to grep the result of an

npm test

from my bash conditional.

So I can stop my CI/CD environment

there is a suggestion to use grep like:

VALID="$(npm test | grep -o 'failing')"

but when I do that, just to try what actually is in the pipeline for "npm test"

VALID="$(npm test)"

What I see is:

echo "$VALID"

> [email protected] test /Users/NE/ts/project
> jest

SO, how will that work? how can I really grep the result of the npm test?

thanks!

Words like "failing" are meant for humans, not for computers. They should use the exit code instead:

if ! npm test
then
  # Tell the human about the failure, if the npm output wasn't enough
  echo >&2 "Testing failed"

  # Exit and tell computers about the failure (0 = success, 1+ = failure)
  exit 1
fi

And you can get the same effect more succinctly:

npm test || exit
