Hobbes

Hobbes is a contract testing library for NodeJS projects. This project is still in development. Expect api changes.

This is based heavily on the Pact library. The difference is that this is meant only for NodeJS and is much more lightweight and flexible.

Installation

``
npm install --save-dev hobbes
`

Usage

Write a consumer test.

`js
import hobbes, { is } from 'hobbes';

describe('Consumer Test Example', () => {
const contract = hobbes.contract({
consumer: 'ConsumerName',
provider: 'ProviderName',
port: 4567,
directory: path.resolve(__dirname, 'contracts')
});

describe('GET /endpoint', () => {
const EXPECTED_BODY = is.object({
value: is.number(1)
});

before(() => {
contract.interaction({
request: {
method: 'GET',
path: '/endpoint'
},
response: {
status: 200,
body: EXPECTED_BODY
}
});
});

it('should get the value', () => {
return getValue().then(value => {
expect(value).to.equal(1);
});
});
});

after(() => contract.finalize());
});
`

Write a provider test:

`js
import hobbes from 'hobbes';

describe('Provider Test Example', () => {
it('should verify the contract', () => {
return hobbes.verify({
baseURL: 'http://provider.com',
contract: path.resolve(__dirname, 'contracts', 'ConsumerName-ProviderName.json')
});
});
});
``

Run the consumer test followed by the provider test.

It's magic.
