gitlab ci runner doesnt know mocha - docker

Question

I have a gitlab.ci with this jobs:
build_image:
stage: build
tags:
- BUILD
script:
# recuperation de la derniere image
- docker pull ${CI_REGISTRY_IMAGE}:${TAG} || true
# build ap artir de la derniere image taggé
- docker build --cache-from ${CI_REGISTRY_IMAGE}:${TAG}
--rm
--pull
--tag ${CI_REGISTRY_IMAGE}:${CI_COMMIT_SHA}
-f cicd/Dockerfile
.
- docker push ${CI_REGISTRY_IMAGE}:${CI_COMMIT_SHA}
only:
- master
- develop
test_api_image:
image: ${CI_REGISTRY_IMAGE}:${CI_COMMIT_SHA}
stage: testbuild
variables:
#on force la connexion au service local
MONGODB_URL: mongodb://mongo:27017/BDD
script:
- npm run cicdtest
tags:
- TEST
only:
- master
- develop
First, in the build job, we build our image with a Dockerfile and we push it on nexus.
In the next job the gitlab runner pull this image, and launch mocha test with "npm run cicdtest"
and we catch this error.
$ npm run cicdtest
> api#0.1.0 cicdtest /builds/data/api
> mocha test/api/**/tests.js --file test/helper --reporter list --exit
sh: mocha: command not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
On my desktop, i pull the same image for test in local and i run and enter the container. When i execute "npm run cicdtest" i have no problems.
Any idea?
For information this is my Dockerfile:
FROM centos:latest
RUN mkdir -p /var/www/myapp
WORKDIR /var/www/myapp
RUN yum update -y \
&& yum install -y gcc gcc-c++ make \
&& curl -sL https://rpm.nodesource.com/setup_14.x | bash - \
&& yum install -y nodejs
COPY ["package.json", "package-lock.json*", "./"]
RUN npm install
COPY . .
EXPOSE 3000
CMD [ "node" , "./src/app.js"]
And my package.json contains:
"dependencies": {
"body-parser": "^1.19.0",
"cors": "^2.8.5",
"crypto-js": "^4.0.0",
"dotenv": "^8.2.0",
"express": "^4.17.1",
"mongoose": "^5.10.13",
"mustache": "^4.2.0",
"nodemailer": "^6.6.0",
"nodemon": "^2.0.6",
"restify": "^8.5.1",
"web-push": "^3.4.4"
},
"devDependencies": {
"chai": "^4.2.0",
"chai-http": "^4.3.0",
"eslint": "^7.26.0",
"eslint-plugin-chai-expect": "^2.2.0",
"husky": "^6.0.0",
"mocha": "^8.3.0",
"supertest": "^6.1.3"
}

Answer 1

Add this line before RUN npm install:
RUN npm install --global mocha
The mocha command works on your local because you installed it globally in the past.

Answer 2

The solution was to add GIT_STRATEGY None because we are testing a built image with code source so we don't need git to checkout source one more time.
test_api_image:
image: ${CI_REGISTRY_IMAGE}:${CI_COMMIT_SHA}
stage: testbuild
variables:
# We do not need GitLab to clone the source code.
GIT_STRATEGY: none
script:
- npm run cicdtest
tags:
- TEST
only:
- master
- develop
