So since I haven't posted in a month, and couldn't think of anything better to discuss, I'm going to share a neat little solution to what I call "The checkbox quandary". It is summarized as follows:
Clicking on a checkbox only changes it's state. Selenium doesn't know how to set it to a specific state. This means that the value of the checkbox could potentially fluctuate each time we run our test. To get around this we typically check the state of the checkbox before we check it. Doing this each time is a pain, so here is a simple setCheckbox routine that does the logic for you. It takes standard locator and a boolean specifying if you want the checkbox checked or not.
public void setCheckbox(string locator, bool isChecked)
