Lesson 15 - PHP Testing - Selenium WebDriver syntax overview

In the previous lesson, PhpBrowser vs. WebDriver and Selenium server configuration, we successfully launched the acceptance tests of our simple PHP calculator. In today's tutorial, we're going to continue with Selenium and go in detail through all what CodeCeption allows us to do. This awareness is very important to avoid reinventing the wheel and writing unnecessarily long and complicated tests. Whenever needed, you can come back here to find the functionality you need. Don't worry about the amount of new information, you're not expected to remember everything in detail :)

Since we have access to the Selenium driver itself as well (the webDriver public property), we can use features that CodeCeption doesn't support directly. But we'll show that not before the end of the course.

If you're a user of add-ons such as AdBlock and alike, be aware that they can, for example, treat opening a new tab by Selenium as advertising and prevent it.

Today's lessons is going to be more theoretical, in other lessons we'll show the practical use of these approaches in real commercial applications.

From the previous lessons, we already know the amOnPage(), see(), click(), fillField(), and submitForm() methods, but we're going to say something more about them anyway.


The first "category" of methods in the AcceptanceTester class are assert methods. By them we assure that a given statement is valid. Let's name them.

  • see (text, context) - Verifies that the page contains a given text (not element). By providing the second parameter, we can specify the context as a selector of the elements in which the text should be searched (e.g. ".menu"). This is useful especially when the same text can be in multiple places on the page, so the test wouldn't reveal an error otherwise. The search is case-insensitive.
  • seeInSource(tex¬≠t), seeInPageSource() -
