How to check if npm script exists?
EDIT:As mentioned by Marie and James if you only want to run the command if it exists, npm has an option for that:
npm run test --if-presentThis way you can have a generic script that work with multiple projects (that may or may not have an specific task) without having the risk of receiving an error.

EDIT
You could do a grep to check for the word test:
npm run | grep -q testthis return true if the result in npm run contains the word test
In your script it would look like this:
#!/bin/bashROOT_PATH="$(cd "$(dirname "$0")" && pwd)"BASE_PATH="${ROOT_PATH}/../.."while read MYAPP; do # reads from a list of projects PROJECT="${MYAPP}" FOLDER="${BASE_PATH}/${PROJECT}" cd "$FOLDER" if npm run | grep -q test; then npm run test echo "" fidone < "${ROOT_PATH}/../assets/apps-manifest"It just would be a problem if the word test is in there with another meaningHope it helps
