Running our tests

Finally, we are able to run our tests! Add the cucumber-js command just prior to the kill command:

npx cucumber-js spec/cucumber/features --require-module @babel/register --require spec/cucumber/steps

 

Your final scripts/e2e.test.sh script should look like this (comments removed):

#!/usr/bin/env bash
if ss -lnt | grep -q :$SERVER_PORT; then
  echo "Another process is already listening to port $SERVER_PORT"
  exit 1;
fi
RETRY_INTERVAL=${RETRY_INTERVAL:-0.2}
if ! systemctl is-active --quiet elasticsearch.service; then
  sudo systemctl start elasticsearch.service
  until curl --silent $ELASTICSEARCH_HOSTNAME:$ELASTICSEARCH_PORT -w "" -o /dev/null; do
    sleep $RETRY_INTERVAL
  done
fi
yarn run serve &
until ss -lnt | grep -q :$SERVER_PORT; do
  sleep $RETRY_INTERVAL
done
npx cucumber-js spec/cucumber/features --require-module @babel/register --require spec/cucumber/steps
kill -15 0

Just to double-check, run the E2E tests to make sure they still pass. Of course, commit these changes to Git:

$ git add -A && git commit -m "Make standalone E2E test script"
