Write a script to perform a website UI testing sequence

Your job is to write a script which performs 26 actions in a website, such as clicking of links or buttons, and while doing so, performs 44 different tests. If any of the tests fail, the script will show which test failed and abort the testing. If all tests pass, the script will inform that all tests passed. After user starts the script, it must run automatically, unattended without the need for any user action. You can implement the script in any language you want, but a Perl script would be preferred. Running of the script must not include installing of any proprietary software. It must be possible to run this script from Ubuntu Linux. The testing script must support JavaScript, as the website to be tested uses JavaScript. Thus a simple WWW::Mechanize based solution will not work. If your solution requires user running the script to install any software or libraries or modules to the system (e.g. perl modules if you implement this in Perl), you must also provide the script or list of commands to run to install the dependencies in Ubuntu Linux. The details of the job (i.e. what actions must be done in the website and which tests run) are in the attached file test_sequence.txt.
