How To

$3

Using this jest preset you can run integration tests in watch mode. In this case, application itself will be launched only once and will work in background.

1. Add preset @tramvai/test-integration-jest to jest.integration.config.js:

`js
module.exports = {
preset: '@tramvai/test-integration-jest',
};
`

2. Add new script for running tests in watch mode to package.json:

`json
{
"scripts": {
"test:integration": "jest -w=3 --config ./jest.integration.config.js",
"test:integration:watch": "jest --runInBand --watch --config ./jest.integration.config.js"
}
}
`

3. Run some test with yarn test:integration:watch . In this case you are able to go to local url http://localhost:3000 and see application at work.
