I am facing an issue with npm test not live reloading when running docker-compose up --build.

My current setup is Window 10 Home, running docker toolbox. With CHOKIDAR_USEPOLLING=true added to the .env file in my project root. Volumes were also mounted according.

I have two services web and tests, running npm start and npm test respectively. The web service live reload upon changes but not the tests service, when adding new test cases.

Testing npm test locally, it live reloads just fine upon adding new test cases.

docker-compose.yml:

version: '3'
services:
  web:
    build:
      context: .
      dockerfile: Dockerfile.dev
    ports:
      - "3000:3000"
    volumes:
      - /app/node_modules
      - .:/app
  tests:
    build:
      context: .
      dockerfile: Dockerfile.dev
    volumes:
      - /app/node_modules
      - .:/app
    command: ["npm", "test"]

Dockerfile.dev:

FROM node:alpine

WORKDIR '/app'

COPY package.json .
RUN npm install

CMD ["npm", "start"]

In your docker-compose.yml, try replacing 

command: ["npm", "test"]

for 

command: ["npm", "run", "test"]
