Mock 'http' objects for testing Express
routing functions, but could be used for testing any
Node.js web server applications that have
code that requires mockups of the request
and response
objects.
This project is available as a NPM package.
$ npm install --save-dev node-mocks-http
Our example includes
--save-dev
based on the assumption that node-mocks-http will be used as a development dependency..
After installing the package include the following in your test files:
var httpMocks = require('node-mocks-http');
Suppose you have the following Express route:
app.get('/user/:id', routeHandler);
And you have created a function to handle that route's call:
var routeHandler = function( request, response ) { ... };
You can easily test the routeHandler
function with some code like
this using the testing framework of your choice:
exports['routeHandler - Simple testing'] = function(test) {
var request = httpMocks.createRequest({
method: 'GET',
url: '/user/42',
params: {
id: 42
}
});
var response = httpMocks.createResponse();
routeHandler(request, response);
var data = JSON.parse( response._getData() );
test.equal("Bob Dog", data.name);
test.equal(42, data.age);
test.equal("bob@dog.com", data.email);
test.equal(200, response.statusCode );
test.ok( response._isEndCalled());
test.ok( response._isJSON());
test.ok( response._isUTF8());
test.done();
};
We wanted some simple mocks without a large framework.
We also wanted the mocks to act like the original framework being mocked, but allow for setting of values before calling and inspecting of values after calling.
We are looking for more volunteers to bring value to this project, including the creation of more objects from the HTTP module.
This project doesn't address all features that must be mocked, but it is a good start. Feel free to send pull requests, and a member of the team will be timely in merging them.
If you wish to contribute please read our Contributing Guidelines.
Most releases fix bugs with our mocks or add features similar to the
actual Request
and Response
objects offered by Node.js and extended
by Express.
