How To Selenium: More Readable Page Objects – Partial Classes C# 7 Features

Reading Time: 2 minutes

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 third article from the WebDriver Page Objects Series. Read the first and second posts of the series. It is dedicated to enhancing page objects with partial classes using the new C# 7.

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. Here I will enhance the code from the last article to make it even more readable though the new features of C#.

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.

First, we use the new body expression syntax for both constructors. Moreover, the second one uses the ?? operator and validates the wait parameter if it is null or not. The third change is that the Navigate method is also converted as a single-line lambda expression.

Now the elements span over a single line of code instead of seven! Even more, we use the getters and setters new lambda syntax in the last property to wrap the element type’s action.

Now the assert method takes only a single line instead of three!
