Simple HTTP request mocking/interception for testing node.js modules that interface with external web services. Inspired by chrisk's fakeweb.

Examples

Fakeweb works by wrapping node's native http lib, so it needs to be required before http.

Catch requests to test.com with uri "/foo":

var fakeweb = require('fakeweb'),
    http = require('http')
http.register_intercept({
    uri: '/foo', 
    host: 'test.com',
    body: 'I'm the mocked-out body!'
})
http.request({uri: "/foo", host: "test.com"}, function(response){
    // ...
})

You can match request properties with regular expressions:

http.register_intercept({uri: /page\d+/, body: 'intercepted body'})

Unregister rules like so:

http.register_intercept({uri: '/page3', body: 'intercepted body'})
// ...
http.unregister_intercept({uri: '/page3', body: 'intercepted body'})

Clear the list of registered intercept rules:

http.clear_intercepts()

Return custom HTTP headers to your fake response:

http.register_intercept({
    uri: '/foo', 
    host: 'test.com',
    headers: {'Content-Type': 'text/pineapple'},
    body: 'I'm the mocked-out body!'
})

node-fakeweb also provides a nodeunit test case that resets the uri intercept list in between tests. See tests/suits/testcase.js for an example.
