How to Write a Test Case in Selenium?

Selenium is an open-source application that automates web browsers. It is employed in web browsers to automate repetitive processes and to test online applications. One of the most widely used programs for automating web browsers is Test Case in Selenium. A tool for capturing and replaying user interactions with a web application is Selenium IDE. We will go over how to use the Selenium IDE to generate the first test case in this article.

A Firefox plugin called Selenium IDE is used to record and replay user interactions with web applications. Users can record their actions in a web browser and play them back as test cases thanks to its user-friendly interface. Programming languages supported by the Selenium IDE include Java, Python, and C#. Check out the online Selenium course to learn more.

Creating the First Test Case in Selenium

We’ll design a straightforward test case that launches the Google homepage and does a term search. To do the same, follow the steps below:

• To begin recording, click the Record button in the Selenium IDE toolbar.
• Go to the homepage of Google.
• Type the term you want to look for into the search box and hit Enter.
• Await the loading of the search results.
• Select the link for the first search result.
• Give the new page time to load.
• To return to the search results page, click the Back button located in the browser toolbar.
• To return to the original search result page, click the Forward button located in the browser toolbar.
• To end the recording, click the Stop button located in the Selenium IDE toolbar.

Now, we have our first test case recorded. Let’s examine what we have captured in more detail.

Understanding the Selenium Test Case

The Selenium IDE has logged multiple commands, which make up our test case. Every command denotes a user action we executed during the test case recording process.

The commands that we have recorded are as follows:

Command 1: Open

The Google homepage is opened with this command. This command receives the URL that we typed in the URL bar as an argument.

Command 2: type

With this command, the desired search term is entered into the Google search window. This command receives the text that we have typed as an argument.

Command 3: keyPress

This command mimics the search box’s Enter key hit action. This command is what started the search process.

Command 4: waitForPageToLoad

This command waits for the loading of the search results page. This command is what we’ve used to ensure that the search results load before moving on to the next step.

Command 5: click

With this command, the first search result link is clicked. This command has been used to mimic a user clicking on a link.

Command 6: wait for the page to load

Once we click on the first link in the search results, our command waits for the new page to load.

Command 7: goBack

Using this command, you can return to the search results page by clicking the Back button in the browser toolbar.

Command 8: waitForPageToLoad

After we click the Back button, this program waits for the search results page to load once more.

Command 9: goForward

Using this command returns to the first search result page by clicking the Forward button in the browser toolbar.

Command 10: waitForPageToLoad

After we click the Forward button, this script waits for the first search result page to load once more.

The commands that the Selenium IDE captured during the process of building our initial test case are listed here. Every command denotes a user action we executed during the test case recording process.

Running Selenium Test Case

We can now run our test case to see if it functions as intended after creating it. The actions below must be taken in order to execute the test case:

• To launch the test case, click the Play button in the Selenium IDE toolbar.
• Await the test case’s execution. As you can see, Selenium IDE is carrying out the tasks that we have described.
• Examine the outcomes in the Selenium IDE log once the test case is finished.

If everything is operating as planned, there shouldn’t be any errors in the test scenario. Should any mistakes arise, we must go over the commands we have written down and address any problems we discover.

Conclusion

We can automate web browsers and build test cases for web applications with the powerful Selenium IDE tool. We have covered how to use the Selenium IDE to generate the first test case in this article. A basic test case that launches the Google homepage and does a word search has been recorded. It then selects the first link in the search results and navigates between the first search result page and the search results page.

An excellent resource for those new to test automation is the Selenium IDE. With its user-friendly interface, users can record their web browser actions and play them back as test cases. The Selenium IDE allows us to write test cases quickly and easily, and automate repetitive tasks in a web browser. To learn more about Test cases in Selenium, check out the Selenium training online.
