    NPM version Build Status Code Climate

    hippie

    Synopsis

    Thin request wrapper that enables powerful and intuitive API testing.

    Features

    • Intuitive and consistent API
    • Built-in and custom expectations
    • Support for custom parsers and serializers
    • Easy to extend
    • Middlewares
    • Works great with any test runner

    Examples

    var api = require('hippie');
    

    Hello world

    hippie()
    .header("User-Agent", "hippie")
    .json()
    .get('https://api.github.com/users/vesln')
    .expectStatus(200)
    .end(function(err, res, body) {
      if (err) throw err;
    });

    Expectations

    hippie()
    .json()
    .base('http://localhost:1234')
    .get('/users/vesln')
    .expectStatus(200)
    .expectHeader('Content-Type', 'application/json; charset=utf-8')
    .expectKey('username')
    .expectValue('username', 'vesln')
    .expectValue('repos[0].name', 'jsmd')
    .expectBody({
      username: 'vesln',
      repos: [
        { name: 'jsmd' },
        { name: 'hippie' },
      ]
    })
    .expectBody(/vesln/g)
    .end(function(err, res, body) {
      if (err) throw err;
      process.exit(0);
    });

    Middlewares

    hippie()
    .json()
    .use(function(options, next) {
      // modify the options for `request` here
      next(options);
    })
    .get('https://api.github.com/users/vesln')
    .end(function(err, res, body) {
      if (err) throw err;
    });

    With middlewares you can modify the options passed to request. Here is an example how you could persist the cookies across multiple requests:

    hippie(app)
    .get('/')
    .use(persistCookies)
    .end(function() {});
     
    function persistCookies(opts, next) {
      opts.jar = true;
      next(opts);
    }

    Serializers and parsers

    var xml = require('my-xml-library');
     
    hippie()
    .serializer(function(params, fn) {
      var err = new Error('Things went wrong');
      var res = xml.objectToXml(params);
      fn(err, res);
    })
    .parser(function(body, fn) {
      var err = new Error('Things went wrong');
      var res = xml.xmlToObject(body);
      fn(err, res);
    })
    .get('https://api.github.com/users/vesln.xml')
    .expectStatus(200)
    .end(function(err, res, body) {
      if (err) throw err;
    });

    AssertionError configurations

    Similar to Chai.js and other frameworks, you can enable showDiff.

    var hippie = require('hippie');
    hippie.assert.showDiff = true;

    showDiff

    DRY

    Since most of the time your test setup is going to be the same, you can simply create a helper function for your tests that will take care of the repetitive setup:

    var hippie = require('hippie');
     
    function api() {
      return hippie()
        .json()
        .serializer(customSerializer)
        .parser(customParser)
        .use(somethingSpecial)
        .base('http://localhost:3000/api/v1')
        .auth('user', 'pass')
        .expect(somethingRepeatable);
    }

    Later on:

    test('my awesome api', function(done) {
      api()
      .get('/users')
      .expectStatus(200)
      .end();
    });

    API

    #timeout

    Configure a timeout for the HTTP request.

    hippie()
    .timeout(1000)
    .end(fn);

    #time

    Configure response time logging for the HTTP request.

    hippie()
    .time(true)
    .end(function(err, res, body) {
      console.log('Response elapsed time: ', res.elapsedTime);
    });

    #qs

    Convert an object to query string values:

    hippie()
    .qs({ foo: 'bar' })
    .end(fn);

    #base

    Configure a base URL, useful when testing the same API endpoint.

    hippie()
    .base('https://api.github.com')
    .get('/users/vesln')
    .end(fn);

    #url

    Set the URL for the HTTP request. Used internally by get, put etc. and it should be used in combination with method.

    hippie()
    .url('https://api.github.com')
    .method('GET')
    .end(fn);

    #method

    Configure the HTTP method. Used internally by get, put etc.

    hippie()
    .url('https://api.github.com')
    .method('OPTIONS')
    .end(fn);

    #header

    Set a request header.

    hippie()
    .header('Content-Type', 'application/json')
    .send({ some: 'data' })
    .end(fn);

    #json

    Helper method for:

    • Content-Type: application/json
    • Accept: application/json
    • Serializer: json
    • Parser: json
    hippie()
    .json()
    .get('https://github.com/vesln.json', fn);

    #form

    Helper method for:

    • Content-Type: application/x-www-form-urlencoded
    • Serializer: urlencoded
    hippie()
    .form()
    .patch('https://api.mindbloom.com/users/vesln')
    .send({ timezone: 'UTC' })
    .end();

    #serializer

    Configure a request body serializer.

    hippie()
    .serializer(function(params, fn) {
      var err = new Error('Things went wrong');
      var res = xml.objectToXml(params);
      fn(err, res);
    });

    #parser

    Configure a response body parser.

    hippie()
    .parser(function(body, fn) {
      var err = new Error('Things went wrong');
      var res = xml.xmlToObject(body);
      fn(err, res);
    });

    #send

    Set request body.

    hippie()
    .json()
    .patch('https://api.mindbloom.com/users/vesln')
    .send({ timezone: 'UTC' })
    .end();

    #auth

    Set Basic Auth credentials.

    hippie()
    .auth('user', 'password')
    .patch('https://api.mindbloom.com/users/vesln')
    .send({ timezone: 'UTC' })
    .end();

    #use

    Register a middleware that will be executed before the HTTP request.

    hippie()
    .json()
    .use(function(options, next) {
      // modify the options for `request` here
      // do other suff
      next(options);
    })
    .get('https://api.github.com/users/vesln')
    .end(fn);

    For example, you can provide a client certificate with your request like so:

    var fs = require('fs');
    hippie()
     .json()
     .use(function(options, next) {
      options.agentOptions = {
       cert: fs.readFileSync('client.crt'),
       key: fs.readFileSync('client.key')
      };
      // Assuming you self-signed the CA
      options.strictSSL = false;
      next(options);
     })
     .get('https://localhost:8080/api/some-api-url')
     .end(fn);

    #get, #del, #post, #put, #patch, #head

    Helper method for:

    • Method: method
    • URL: url
    • End: fn [optional]
    hippie()
    .get('https://api.github.com/users/vesln')
    .end(fn);

    Or if you want to execute the test immediately:

    hippie()
    .get('https://api.github.com/users/vesln', fn);

    #expectStatusCode, #expectStatus, #expectCode

    Set a response status code expectation.

    hippie()
    .json()
    .get('https://api.github.com/users/vesln')
    .expectStatus(200)
    .end(fn);

    #expectHeader

    Set a response header expectation.

    hippie()
    .json()
    .get('https://api.github.com/users/vesln')
    .expectHeader('Content-Type', 'application/json; charset=utf-8')
    .expectHeader('X-API-LIMIT', 3)
    .end(fn);

    #expectValue

    Register a string path expectation.

    hippie()
    .json()
    .get('https://api.github.com/users/vesln')
    .expectValue('details.company', 'Awesome.io')
    .expectValue('repos[0].name', 'hippie')
    .end(fn);

    For more information about string paths visit pathval.

    #expectKey

    Register a string path expectation for a given key.

    hippie()
    .json()
    .get('https://api.github.com/users/vesln')
    .expectKey('details.company')
    .expectKey('repos[0].name')
    .end(fn);

    For more information about string paths visit pathval.

    #expectBody

    Strict expectations:

    hippie()
    .get('https://api.github.com/users/vesln')
    .expectBody('{ "username": "vesln" }')
    .end(fn);

    Regular expression expectations:

    hippie()
    .get('https://api.github.com/users/vesln')
    .expectBody(/vesln/)
    .end(fn);

    Object/array expectations:

    hippie()
    .get('https://api.github.com/users/vesln')
    .expectBody({ username: 'vesln' })
    .end(fn);

    #expect

    Register a custom expectation.

    hippie()
    .get('https://api.github.com/users/vesln')
    .expect(function(res, body, next) {
      var err = assertSomething;
      next(err);
    })
    .end(fn);

    #end

    Execute the HTTP request and the tests.

    hippie()
    .json()
    .get('https://api.github.com/users/vesln')
    .expectValue('details.company', 'Awesome.io')
    .expectValue('repos[0].name', 'hippie')
    .end(fn);

    When no callback is provided, end() returns a promise.

    hippie()
    .json()
    .get('https://api.github.com/users/vesln')
    .expectValue('details.company', 'Awesome.io')
    .expectValue('repos[0].name', 'hippie')
    .end()
    .then(function(res) {
      console.log(res);
    })
    .catch(function(err) {
      console.error(err);
    });

    #app

    Fire up an HTTP app and set its address as a base URL. Also works with HTTP handler functions function(req res){}.

    hippie(expressApp)
    .get('/')
    .end(fn);
    hippie()
    .app(function(req, res) {
      res.end('Bye');
    })
    .get('/')
    .end(fn);
