Particularly crucial and broadly applied in the arena of web-based software, automated testing facilitates cost-efficient User Interface (UI) testing, a critical element in offering high-quality services.
Selenium is a renowned open-source automation tool designed for web application testing. It comes loaded with a host of features, including the ability to refactor web attributes into reusable classes easily utilized in testing scenarios, among others.
However, those new to automation testing might discover that these sophisticated features do not align with their testing requirements. Some might prefer to bypass the complexities, focusing instead on writing tests promptly and understanding design tenets as they proceed.
In such instances, Katalon Studio could be an optimal choice.
This guide offers an accessible introduction to automation testing, employing Selenium and Katalon Studio.
In the initial segment, we’ll automate a login test case utilizing Selenium, a web testing tool. Meanwhile, in the second part, you’ll explore how to accomplish the same objective more effortlessly with Katalon Studio.

Attainable Learning Outcomes:
Katalon Studio Vs Selenium
Scripting Automated Tests via Selenium
Selenium is an open-source tool designed to automate web browsers. It presents a unified interface that facilitates scripting tests in several programming languages, including Ruby, Java, NodeJS, PHP, Perl, Python, and C#.
Selenium enables considerable flexibility in translating programming expertise to software testing, which we’ll illustrate in the subsequent stages.
In this segment, you will learn how to:
- Fabricate a Maven project in Eclipse
- Deploy Selenium
- Access LinkedIn through Selenium
The following are the prerequisites:
- An operating system with pre-installed Java
- Eclipse IDE (or a similar Java-compatible IDE supporting Maven)
- ChromeDriver
Construction of a Maven Project in Eclipse
Creating a Maven project in Eclipse offers the convenience of defining necessary libraries within a file, which can later be auto-downloaded and employed.
To get rolling:
- Right-click anywhere within the Package Explorer tab.
- Select New => Other to open a fresh window.
- Type “Maven” into the search box and choose Maven Project.
- Click Next across each panel until arriving at the Specify Archetype Parameters step.
- Provide your inputs during the Specify Archetype Parameters stage.
- Click Finish.
And voila! You now have a Maven project at your disposal. The App.java and pom.xml files are the most relevant ones – the primary class for your program and the document where you state your libraries, respectively.
Click here to obtain further understanding about the Maven project creation process.
Selenium Installation
Having set up your Maven project, you can proceed with Selenium’s hassle-free installation by merely copying and pasting the succeeding code chunk into your pom.xml file, stationed between the <dependencies></dependencies> tags:
<!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java --> <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>3.141.59</version> </dependency> </dependencies>
Consequently, your pom.xml file should feature the Selenium dependency and resemble the model indicated below:
Save the document and await Eclipse to import the dependencies. You can now commence using Selenium via your code.
Login to LinkedIn Using Selenium
Incorporate the following code fragment into the main function of your App.java file:
System.setProperty("webdriver.chrome.driver","pathToChromeDriver"); WebDriver driver = new ChromeDriver(); driver.get("https://www.linkedin.com/"); WebElement inputUsername = driver.findElement(By.xpath("//input[@id='login-email']")); inputUsername.sendKeys("yourLinkedinUsername"); WebElement inputPassword = driver.findElement(By.xpath("//input[@id='login-password']")); inputPassword.sendKeys("yourLinkedInPassword"); WebElement btnLogIn = driver.findElement(By.xpath("//input[@id='login-submit']")); btnLogIn.click();
The above code leverages the XPath locator in identifying the web elements in conjunction with the username and password fields, as well as the login button.
After running your application, the browser should launch, redirecting to LinkedIn for an automated login to your account.
Scripting Automated Tests via Katalon Studio
In this part, the goal is to assist you in achieving similar outcomes as before, but with substantially reduced effort using Katalon Studio.
Katalon Studio is an efficient testing tool designed for web, API, and mobile testing. Its simple approach allows testers to draft reliable automated test cases regardless of coding know-how, courtesy of its in-built IDE.
The tool also provides predefined templates for artifacts including test cases, test suites, and test suite collections, thereby making it a breeze to manage tests.
Katalon Studio unifies capabilities from Selenium, ChromeDriver, and a scripting interface in one application, eliminating the need for additional setup. Just fire up Katalon Studio and begin architecting your tests.
Here’s what you will learn:
- Creation of a web testing project in Katalon Studio
- Utilization of the web recorder
Here are the only prerequisites:
- Katalon Studio (download here)
- Chrome web browser
Create a Web Testing Project in Katalon Studio
Your first task is to establish a fresh project.
Launch Katalon Studio, designating Web as your project type before clicking OK.
Usage of Web Recorder
Once a web project has been established in Katalon Studio, you can trigger the web recording element by clicking on its icon as pictured below.
Select chrome as your browser and commence the recording.
The Chrome browser should launch directing you to linkedin.com. Any interactions on this browser will be subsequently recorded in real-time, with correlated steps displayed via the web recorder. You can conduct a normal login process to your account.
Following the conclusion of the recording, click OK. Subsequently, preserve your test case and test objects. To execute the test case, click the Play symbol as demonstrated below.
Your interactions should be replayed in the exact sequence recorded. This is how you draft a test case using Katalon Studio.
Conclusion
Through this tutorial, we now understand basic automation testing via Selenium and Katalon Studio.
In Katalon Studio, test items are structured according to the Page-Object Model, encouraging reusability throughout multiple test cases. Website interactions can be captured using the web recorder, which serves as a foundation for more complex test scenarios.
For automation testing rookies, initiating with best practices found in Katalon Studio is advised before venturing into Selenium due to the latter’s more demanding learning curve.
As you improve, programming may be required for further upgrades to your automation tests. Katalon Studio permits leveraging all Selenium features via its provided interface, with support for Java and Groovy.
However, if you’re already seasoned in the programming realm or prefer not to master a new language, Selenium may be your ideal pick, offering APIs available in various programming languages such as C#, Ruby, Perl, Python, R, and more.
