+You also need NodeJS installed locally : we **strongly** advise to install [Node Version Manager](https://github.com/nvm-sh/nvm) and use the latest LTS version of Node (check that your local version matches with the one used in the Dockerfile).
+
+The API will run inside a docker container, **but** the install itself is made outside the container, because during development we need tools that need to be available locally (eg. ESLint, Prettier...).

 A RabbitMQ instance is also required to send / receive messages when data has been inserted/updated/deleted.

-## Test
+## Tests
+
+Tests are run outside the container for ease of use (switching between different environments inside containers using prisma is complicated and error prone).
+The integration tests use a dedicated database (see *db-test* section of *docker-compose.yml*).
 
 ```bash
-# unit tests
-docker exec v3_user sh -c "npm run test"
+# run all tests (unit + integration)
+npm run test
 
-# test coverage
-docker exec v3_user sh -c "npm run test:cov"
+# unit tests only
+npm run test:unit

+# integration tests only
+npm run test:integration
+
+# coverage
+npm run test:cov
 ```
 
-Note : you can run all npm commands directly _outside_ the container (see _scripts_ section of `package.json` for available commands), but you need NodeJS installed locally. We **strongly** advise to install [Node Version Manager](https://github.com/nvm-sh/nvm) and use the latest LTS version of Node.
