An attribute of an HTML tag (or WebElement as you might know it from Selenium) stores valuable information about the state of that element. If we are thinking of checkboxes, a “checked” attribute will signal whether the checkbox is selected or not. For a link, the “href” attribute will tell us what location on the web it points to.
There will be times when your Selenium tests will need for an attribute of a WebElement to have an expected value. This signals that the state you expect your product to be in is correct. Before any other steps will be performed, you will need to make sure that the value of the attribute is correct, and for this process asserts are quite frequent. Enter “thewaiter” library, which has methods for you to wait for the attributes, not only to equal a text, but to also contain it, or to equal/contain it ignoring whitespaces or the case. Continue reading thewaiter: wait for WebElement attribute. To equal, contain a String, with variations.
