How To Selenium: Page Objects – Partial Classes String Properties

This is the latest post as part of the Huddle Selenium series.

Each month on the first Tuesday of the month, we will post a new blog post to take you through a step-by-step guide on how to address a particular aspect of using Selenium as part of our How To series.


This is the fifth article from the WebDriver Page Objects Series. It is dedicated to page objects using partial classes and exposing elements as string properties.

In the previous articles from the series, I showed you how to create more maintainable page objects through separating the code of the pages in three different files. Moreover, you are no more obligated to use the Selenium.Support NuGet package. The primary difference compared to the other versions of the pattern will be that here we will not expose the whole interface of the elements. Instead, we will use them as string properties, simplifying the API.

If you are using WebDriver often, you may find useful my Most Complete Selenium WebDriver C# Cheat Sheet. All you need to know- the most basic operations to the most advanced configurations.

Test Case

We will once again automate the main Bing page. All of the code is placed inside the BingMainPage class.

BingMainPage

 

Page Objects using String Properties Code

BingMainPage Initial Version

BingMainPage String Properties’ Version

The difference here is that we do not call the SendKeys method anymore. Instead, we assign the value directly to the element’s property.

 

BingMainPage.Map Initial Version

BingMainPage.Map String Properties Version

As you can see we wrap the nitty gritty details of the WebDriver’s API here directly in the properties. Then return only the required information instead of the whole IWebElement object. This way the users of your pages/API will not be able to shoot themselves in the foot.

BingMainPage.Asserter Initial Version


As demonstrated, here we get the text in the element through the Text property of the element.

BingMainPage.Asserter String Properties Version


The primary difference is that we access the inner text of the element without the call to the Text property.

 

Elements’ String Properties in Tests


You can create service methods for most common operations as we did with the Search method. However, you can use the elements’ string properties directly as shown in the example tests.
