In this article, I am going to practically demonstrate the usage of CSS Selector locators for locating the UI elements on the Web Pages.
Note: This article is just for demonstrating CSS Selectors at a high level. CSS Selectors will be explained in detail in the upcoming articles.
Let’s get started.
Locators for Selenium – Demonstrating CSS Selector Locator
Follow the below steps for locating the UI elements on the Web Pages using CSS Selector Locator:
1) Install Selenium IDE, if not installed in your chrome browser (Refer steps to install Selenium IDE in your chrome browser)
2) Navigate to http://omayo.blogspot.com/ in your chrome browser as shown below:
3) Right click on the ‘ClickToGetAlert’ button and select ‘Inspect’ option as shown below:
4) Observe that the HTML code related to the ‘ClickToGetAlert’ button got highlighted as shown below:
5) Right click on the above-highlighted HTML line and select ‘Copy’ > ‘Copy selector’ option as shown below:
6) Launch Selenium IDE from Chrome Browser by following the steps provided in below article:
7) Enter any Selenium IDE command say ‘Click’ into the ‘Command’ Text box field as shown below:
Note: Without entering this command ‘Find target in Page’ magnifier icon option will be in a disabled state by default and will be enabled only after entering any command into the ‘Command’ text box field as shown below:
8) Now, type css= into the Target text box field as shown below:
9) Paste the CSS Selector copied earlier (i.e. in Step 5) into the ‘Target’ Text box field and click on ‘Find target in Page’ search icon option as shown below:
10) Observe that the ‘ClickToGetAlert’ button on the Web Page got highlighted for a second on clicking the ‘Find target in Page’ option in the above step using the css=#alert1 locator provided in the Target field as shown below:
As the ‘ClickToGetAlert’ button got highlighted using the CSS Selector locator (i.e. css=#alert1) provided in Selenium IDE, we can confirm that the give CSS Selector locator is able to locate the ‘ClickToGetAlert’ using its HTML code’s CSS Selector.
Hence in this example, we have used the CSS Selector locator (i.e. css=#alert1) for locating the ‘ClickToGetAlert’ button on the Web Page.
In the next article, I will demonstrate the next locator i.e. XPath Expression locator for locating the UI elements on the Web Page.
