## Serenity/JS REST

[`@serenity-js/rest`](https://serenity-js.org/api/rest/) module lets your actors interact with and test HTTP REST APIs.

### Installation

To install this module, as well as [`axios` HTTP client](https://github.com/axios/axios),
run the following command in your computer terminal:

```sh
npm install --save-dev @serenity-js/core @serenity-js/rest @serenity-js/assertions axios
```


### Example test

```typescript
import { actorCalled } from '@serenity-js/core'
import { CallAnApi, DeleteRequest, GetRequest, LastResponse, PostRequest, Send } from '@serenity-js/rest'
import { Ensure, equals, startsWith } from '@serenity-js/assertions'

const actor = actorCalled('Apisit').whoCan(CallAnApi.at('https://myapp.com/api'))

await actor.attemptsTo(
    // no users present in the system
    Send.a(GetRequest.to('/users')),
    Ensure.that(LastResponse.status(), equals(200)),
    Ensure.that(LastResponse.body(), equals([])),

    // create a new test user account
    Send.a(PostRequest.to('/users').with({
        login: 'tester',
        password: 'P@ssword1',
    }),
    Ensure.that(LastResponse.status(), equals(201)),
    Ensure.that(LastResponse.header('Location'), startsWith('/users')),

    // delete the test user account
    Send.a(DeleteRequest.to(LastResponse.header('Location'))),
    Ensure.that(LastResponse.status(), equals(200)),
)
```
