How to test Firestore Security Rules with Jenkins? - firebase

Question

I'm developing some Firestore security rules locally. I use mocha to test the rules, and locally everything works. I've a Jenkins pipeline that every time I merge a PR on develop it published the rules on Firebase in cloud. What I want to do is running my unit tests within Jenkins. Anyway, every time Jenkins calls yarn test from the pipeline, I get an error that says
#firebase/firestore: Firestore (7.18.0): Could not reach Cloud Firestore backend. Connection failed 1 times. Most recent error: FirebaseError: [code=internal]: 13 INTERNAL: Received RST_STREAM with code 2 triggered by internal client error: Protocol error
This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.
Is there a way to run the firebase emulators from Jenkins?
Thanks!

Answer 1

I found a way to do that.
By using firebase-tools-docker I can easily run my tests inside a docker container that brings up the emulators suite.
The Jenkinsfile goes like this:
def jenkinsUser = 1001
def firebaseDocker = 'andreysenov/firebase-tools:9.14.0'
stage('Pull docker image') {
sh "docker pull $firebaseDocker"
}
stage('Unit tests') {
sh "docker run -d --rm \
--user $jenkinsUser:$jenkinsUser \
-p 8080:8080 \
-v ${pwd()}:/home/node \
--name firebase-emulators \
$firebaseDocker \
firebase emulators:start"
sleep(5)
sh "docker exec firebase-emulators /bin/bash -c 'cd tests && yarn test'"
sh "docker stop firebase-emulators"
}
This is my folder structure (for reference):
Hope this helps 😉
