HTTP integration testing with Chai assertions.
- integration test request composition
- test http apps or external services
- assertions for common http tasks
- chai
expectandshouldinterfaces
This is a addon plugin for the Chai Assertion Library. Install via npm.
npm install chai-http
Use this plugin as you would all other Chai plugins.
var chai = require('chai')
, chaiHttp = require('chai-http');
chai.use(chaiHttp);Chai HTTP provides and interface for live integration testing via superagent. To do this, you must first construct a request to an application or url.
Upon construction you are provided a chainable api that allow to you specify the http VERB request (get, post, etc) that you wish to invoke.
You may use a function (such as an express or connect app) or a node.js http(s) server as the foundation for your request. If the server is not running, chai-http will find a suitable port to listen on for a given test.
chai.request(app)
.get('/')You may also use a base url as the foundation of your request.
chai.request('http://localhost:8080')
.get('/')- @param {Function} callback
- @cb {Request} object
- @cb {Function} next (optional)
- @returns {this} for chaining
You may optionally use .req chainable to hook
into the the request preperation invocation. Use
this to modify the request object to include post
or querystring parameters, attach a file for
upload, or any other operation that superagent
provides.
chai.request(app)
.get('/')
.req(function (req) {
req.set('x-api-key', 'abc123');
})- @param {Function} callback
- @cb {Response}
Invoke the request to to the server. The response
will be passed as a paramter to this function so
that further testing may be done. Use the chai-http
assertions for testing.
chai.request(app)
.get('/')
.res(function (res) {
expect(res).to.have.status(200);
});The Chai HTTP module provides a number of assertions
for the expect and should interfaces.
- @param {Number} status number
Assert that a response has a supplied status.
expect(res).to.have.status(200);- @param {String} header key
- @param {String} header value (optional)
Assert that an object has a header. If a value is provided, equality to value will be asserted.
expect(req).to.have.header('x-api-key');
expect(req).to.have.header('content-type', 'text/plain');Assert that an object has headers.
expect(req).to.have.headers;Assert that a string represents valid ip address.
expect('127.0.0.1').to.be.an.ip;
expect('2001:0db8:85a3:0000:0000:8a2e:0370:7334').to.be.an.ip;Assert that a Response or Request object has a given content-type.
expect(req).to.be.json;
expect(req).to.be.html;
expect(req).to.be.text;Assert that a Response redirects, optionally to a given url.
expect(res).to.redirect;
expect(res).to.redirectTo('http://example.com');(The MIT License)
