Simple utility server for mocking requests and responses in CasperJS.

Warning: it's experimental and work in progress.

var casper = require('casper').create();
require('casperserver.js').create(casper, {port: 8007});
casper.server.start();

// Loading default file index.html
casper.start('http://localhost:8007', function (){
    this.test.assertTitle('Title from index.html', 'index.html is loaded and title is correct');
});

casper.then(function () {
    // This will indicate the content of the response to serve to this path
    this.server.watchPath("/a-path-or-a-regex/", {content: "the content of the response"});
    // can be also:
    this.server.watchPath("/a-path-or-a-regex/", {content: function(request) {
        /* do something according to the request values*/
        return content
        }
    });
    // then do some tests of you application needing to access to the given path
});


casper.then(function () {
    path = "/123/";
    // again, define what to respond to path /123/
    this.server.watchPath(path, {content: "ok"});
    // Indicate to store the request
    this.server.watchRequest(path);
    // Do something that POST to "/123/"

    // Then get the request
    var request = this.server.getWatchedRequest(path);
    // And check it
    this.test.assertTruthy(request, "Request has been catched");
    this.test.assertEqual(request.method, 'POST', 'POST received');
    this.test.assertEqual(request.post.myfield, "myvalue", 'POST myfield value is correct');
});

More examples on the server.js tests file

You need to attach the server to the casper instance

require('casperserver.js').create(casper, {port: 8007});

You can optionaly watch path without having started the server

You must start the server

casper.server.start();

Now every request sent on port 8007 (for example) will be addressed by our testserver. The default behaviour is to look for files in the responsesDir corresponding to the requested URL (after having replaced the / by _). For example, the content for the path /some/path/22/ will be looked into the file some_path_22 in the responsesDir directory.

Then you can watchPath, for serving some path specifically, and watchRequest, to be able to auscultate a request sent by your application (for exemple to check the post parameters values).

## API

Options:

• port: (int, default: 8007) the port the server will listen to
• defaultStatusCode: (int, default: 200) the default status code of the response
• responsesDir: (string, default: "./") the path where to look for responses content

Tell the server how to serve this specific path.

Note: each option can be a string OR a function getting the request as parameter

path: a string or a regex-like string to catch requests from their path

options:

• content: (string or function) content of the response to serve
• filePath: (string or function) path to a file where to get the content to server (can be relative to responsesDir or absolute)
• statusCode: (string or function) status code of the response to serve
• permanent: (boolean, default: false) if true, does not automatically unwatch served path

Tell the server to forget some watched path. Note that by default, if a watched path is not set to permanent=true, the path will be automatically unwatched when it has matched once.

path: (string) the path to watch

Tell the server to forget some watched path.
