End-to-end testing with CasperJS

This recipe expands on CasperJS by introducing how to work with its testing API. We will demonstrate how to create and run a simple end-to-end test.

Getting ready

To run this recipe, the CasperJS binary must be installed and on our PATH; we will also need a script that expects to use the CasperJS API, particularly the tester module for executing assertions and tests.

The script in this recipe is available in the downloadable code repository as recipe08.js under chapter05. If we run the provided example script, we must change to the root directory for the book's sample code.

Lastly, the script in this recipe runs against the demo site that is included with the cookbook's sample code repository. To run that demo site, we must have Node.js installed. In a separate terminal, change to the phantomjs-sandbox directory (in the sample code's directory), and start the app with the following command:

node app.js

How to do it…

Consider the following script:
