If you have a coding background I would suggest writing some basic automated tests with Selenium WebDriver. This will allow you to find elements on the page via their ids, get text from textfields, click on links, and verify that another page has loaded (sounds like the tasks you wish to perform?). You can structure your tests so they run through the main functionality path (eg. go from log in, to main screen, to another screen, testing all functionality along the way) and then you will only have to write a few tests. If you want full automation it is usually better to have specific requirements for your application and write a separate test for each. The Selenium homepage has some good documentation with code snippets to get you started, and a simple google search should provide you with several tutorials. Good luck :)
