Do you want to rewrite this? Do you want to rewrite this?

I have a node webapp that I run locally to run test specs. I use mocha and karma as a spec runner. Here are one of my npm commands to run a test suite:

{
  "scripts": {
   "test-jobs-once-docker": "mocha --reporter spec "server/**/*.spec.js""
  }
}

When I run docker-compose up locally, the command works and the specs run in the docker container.

Here is my docker-compose.yml:

version: "3"
services:  
  mongo:     
    image: mongo:3.4
    ports:
      - 27017:27017
    restart: always    
  redis:
    image: redis:7.0.8    
    ports:
      - 6379:6379
    restart: always        
  webapp:
    build:
      context: .
      args:
        - NODE_ENV=dockerTest
    platform: linux/amd64
    ports:
      - 9000:9000
    depends_on:
      - redis
    environment:
      - PORT=9000
      - NODE_ENV=dockerTest
      - REDIS_URL=redis://redis:6379            
    command: ['npm', 'run', 'test-jobs-once-docker']

Here is the Dockerfile:

FROM --platform=linux/amd64 ubuntu:20.04

ENV APP_HOME="/app"

COPY .npmrc ./

RUN npm install
COPY . /app


RUN touch ./server/config/local.env.js

ENV PORT=9000

EXPOSE 8080
EXPOSE 9000

However, when I run this in GitHub Actions it says:

mocha: command not found

Here is my workflow:

name: Run Test Suite
on: [push, pull_request]

jobs:
  run-tests-docker:
    runs-on: ubuntu-20.04
    steps: 
    - name: Check out code
      uses: actions/checkout@v2

    - name: Build Docker Containers & Run Test Specs
      run:  docker-compose -f "docker-compose.yml" up -d --build
          
    - name: Run Test Specs
      run:  npm run test-jobs-once-docker
      env:
        NODE_ENV: dockerTest
   
    - name: Stop Containers
      if: always()
      run: docker-compose -f "docker-compose.yml" down

When I run this on GitHub Actions, I comment out the command property on the webapp in the docker-compose.yml so the command is executed in the job on GitHub Actions instead of when the container builds. I feel like this is the problem. I am not sure how to inspect the container that is built and used in GitHub Actions to see if the node_modules exists.

Does anybody know how I can get access to the mocha executable so I can run my tests in GitHub Actions?

Update:

I noticed that the node_modules folder is not in the directory the rest of my app is in. I’m going to guess this is part of the problem, this is the $PATH variable and files in the directory after the environment builds in github actions (also note the Dockerfile and nvm
