Casper.JS Assertions for Chai

Casper–Chai provides a set of custom assertions for use with CasperJS. You get all the benefits of Chai to test with CasperJS.

It is an alternative to Casper's built-in Tester. Instead of using Casper's Tester you can use (in this case with Mocha and Chai):

describe("my page", function () {
  it("can be opened by Casper", function () {
    casper.open("http://www.google.com")

    casper.then(function () {
      expect(casper.currentHTTPStatus).to.equal(200);
    });

    casper.then(function () {
      expect("Google").to.matchTitle
    });
  });
});

Tests

Name	Description
fieldValue(value)	the named input provided has the given value
inDOM	when the given selector is in the DOM
loaded	when the given resource exists
matchCurrentUrl	the current URL matches
matchOnRemote	compare the remote evaluation to the given expression
matchTitle	the current Title matches
textInDOM	the text can be found in the DOM
textMatch(expression)	the text of the given selector matches the expression (a string or regular expression).
trueOnRemote	the remote expression evaluates to something truthy
visible	the selector matches a visible element

For even more examples, if you are cool with CoffeeScript, check out the unit tests.

Installation

Casper-Chai can be installed with npm using npm install casper-chai, or including build/casper-chai.js in a directory require will find it.

Add extensions to Chai with:

casper_chai = require('casper-chai');
chai.use(casper_chai);

To build locally, clone the project and run cake toast test in the project directory. You may have to run npm install to get dependencies (which, obviously, requires npm to be installed), and make sure cake is available - which should be possible by running npm install -g coffee-script.

AMD

Casper–Chai supports being used as an AMD module, registering itself anonymously (just like Chai).
