In this Selenium Java tutorial, I will be referencing on Class name locator in Selenium to demonstrate how to locate an element on a webpage via class name.

Getting Started With Class Name Locator In Selenium With Example

Next, in this Selenium Java tutorial, we will consider the scenario of Airbnb, where we intend to locate the ‘Where’ field in the search form of Airbnb homepage via class name. Below is a screenshot of Airbnb page where we inspect the ‘Where’ field in the form.

In-order to use Class name locator in Selenium we need to use the below syntax:
findElement(By.className("_up0kwni "))

Now, let’s look into the code for finding elements by Class name in locators:

Pretty simple, isn’t it? In the upcoming session of this Java Selenium tutorial we will learn how to handle a common exception for class name locator in Selenium.

One Of The Most Common Exceptions For Class Name Locator In Selenium

Another interesting fact and a popular error you may come across while using Class name locator in Selenium would be something like:

I am sure, you may have come across this error. Lets try to incorporate this scenario in the below code snippet for the Facebook sign up page. Below is the DOM structure for facebook ‘first name’ field with class name attribute highlighted below:

locators in selenium

Referenced code snippet, trying to access the first name field using the class name locator in Selenium:

Referenced Console error below:

How to handle this error? Well, Selenium considers this as a compound class, which means more than one classes marked through spaces. So, any class name with spaces in it will be considered two or three or more classes.

In this case, this class name marked as ‘inputtext _58mg _5dba _2ph-‘ contains three spaces thereby making it three different classes. Hence, Selenium mentions the error stating it cannot find multiple classes together. In this case, you can opt to locate element by CSS selector in Selenium or by XPath in Selenium using the class name attribute. The referenced code snippet below:

How To Locate An Element When We Have Multiple Elements Sharing The Same Class Name?

Now you know when to use the class name and when you cannot use class names. But did you ever imagine the scenario when you have multiple elements sharing the same class name? How do you tackle that situation? This is again something, you can simply achieve by using the findElements keyword. All you need to do is, locate all elements with that class name using the findElements keyword and iterate through the required element class name via index. Having said so, I would rather suggest looking into an alternative method of locating that element rather than this. As its tendency of breaking will be pretty high and may lead to errors.

Example For Class Name Locator In Selenium For Multiple Elements With A Similar Class Name

Let’s consider the below example, highlighting the scenario above. In this case, we are considering the LinkedIn sign-up page, where all fields share the same class name. In this case, we need to note two important things:

  • If no, the index is defined, then by default selenium selects the first element it encounters with that class name. In the code snippet below, it locates the first element which is the first name:

Note: Take a look at the class name, which in this case is cell-body-textinput, since it is not marked with spaces hence it is considered as a single class.

  • Locating the different elements with the same class name using index. The referenced snippet below:

Console output:

Bingo, you are good to go now. This was all about class name locator in Selenium.

What Did We Learn About Class Name Locator In Selenium?

Well, that was all for today’s Selenium Java tutorial for CSS locator in Selenium. I am sure by far you have developed a deep understanding on how to use the Class name locator in Selenium effectively. We came across the most common error across the implementation of Class name locator in Selenium. We also learned how to overcome complicated scenarios where multiple elements are sharing a similar class name. Adios, happy testing! 🙂
