Running Jest Integration Tests
Description
We're incrementally moving integration tests out of Meteor+Mocha and into pure Jest tests. Jest integration test files end in .test.js and are all located in the /tests folder.
Prerequisites
Install watchman if you are on Mac OSX and you'd like to run --watch or --watchAll on tests (such as the npm run test:integration:watch command).
brew install watchman
Run tests
To run tests:
npm run test:integration
Run tests in watch mode
To run tests and rerun as you make changes to test files:
npm run test:integration:watch
Run tests within a Docker container
You can use Docker Compose to run a local development container and run tests within it. This gives a more accurate picture of how production code running in a container will behave.
docker-compose run --rm devserver npm run test:integration
(This will also work with :watch suffix for watch mode.)
