httpmock.js is a server that serves mostly static content. Its configuration is specified by an external file in a DSL.
The goal is to allow easy specification of mock servers for client testing.
It began as a node.js port of restmock (https://github.com/tildedave/restmock).
Install with npm:
npm install https://github.com/tildedave/httpmock.js/tarball/0.0.1
Run with node:
node ./node_modules/httpmock/httpmock.js --config mock.js
Specify the server's behavior in a configuration file (config.js) and then start the server:
node httpmock.js --config config.js
routes(
route("Hello, world!",
request(uri("/hello")),
response(text("Hello, world!"))),
route("Can retrieve all the kittens",
request(uri("/kittens"),
method.GET),
response(text("Some adorable kittens!"))),
route("Can't make a new kitten",
request(uri("/kittens"),
method.POST),
response(status(422))),
route("Can update a kitten",
request(uri("kittens/([0-9]+)"),
method.PUT),
response(status(422))),
route("Can check a kitten's async status",
request(uri("kittenjobs/([0-9]+)"),
method.GET),
response(time(1, json({ done : false })),
time(2, json({ done : false })),
otherwise(json({ done : true})))))
Because the server configuration is JavaScript, it is possible to script dynamic behavior into an otherwise static server.
Functions inside a request determine if an incoming HTTP request
matches the given route.
Some built-in matchers are uri and method.
Custom matcher objects should have a function matches that returns
true or false.
Here is an example of a custom matcher that will match a request's accept header.
var accepts = function(acceptsType) {
return {
matches : function (req) {
var accept = req.headers.accept;
if (!accept) {
return false;
}
return accept.indexOf(acceptsType) != -1;
}
};
}
routes(
route("JSON data",
request(uri("/data"),
accepts("application/json")),
response(json({ success: true }))),
route("other kinds of data",
request(uri("/data")),
response(text("succeeded!"))));
