service-tester
===============

!main CI


This module makes it easier for you to write tests for your node.js @openapi-typescript-infra/service microservice.
Simply add the module as a dev dependency:

``sh
yarn add -D @openapi-typescript-infra/service-tester
`

Then write a test in `/__tests__/startup.test.js`:

`ts
import request from 'supertest';
import { getReusableApp, clearReusableApp } from '@openapi-typescript-infra/service-tester';
import myService from '../src/index';

describe('my service', () => {
test('should start', async () => {
const app = await getReusableApp(myService);
expect(app).toBeTruthy();
await request(app).get('/').expect(200);
});
});
`

Service call mocking
--

Nock is so 2010. The future is mock! Since we have typed clients for services these days, mocking them is easier. We've played some nutty
tricks with Typescript (well, nutty for me), to enable this kind of syntax:

`
mockServiceCall(app.locals.services.myCrazyServ, 'get_some_resource').mockResolvedValue({
status: 200,
responseType: 'response',
body: { resource: true },
headers: new Headers(),
});
`

This will cause calls to app.locals.services.myCrazyServ.get_some_resource() to return {resource: true}. This is just shorthand
for jest.spyOn(service, 'method')` with knowledge of the traditional return type of OpenAPI service calls.
