How To Simplify Selenium Tests In Katalon Studio

Katalon Studio is a popular test automation tool that provides various functionalities to automate web, mobile, and API testing. One of the significant features of Katalon Studio is its integration with Selenium, a widely used test automation framework. Selenium allows you to write test scripts in various programming languages such as Java, C#, Python, and Ruby. However, writing Selenium tests can be complex and time-consuming. In this blog, we will discuss how to simplify Selenium tests in Katalon Studio.

Understanding Selenium tests in Katalon Studio

Before we dive into the ways to simplify Selenium tests in Katalon Studio, let’s first understand how Selenium tests work in Katalon Studio. Katalon Studio provides a dedicated Selenium WebDriver that helps you to automate web-based applications. The Selenium WebDriver is used to launch the web browser, navigate to a particular URL, and interact with the web page elements. The following code snippet shows how to open a web page using the Katalon Studio Selenium WebDriver:

import com.kms.katalon.core.webui.driver.DriverFactory

import org.openqa.selenium.WebDriver

// Get the Katalon Studio Selenium WebDriver instance

WebDriver driver = DriverFactory.getWebDriver()

// Navigate to the web page

driver.get(“https://www.google.com“)

With the above code, we first import the required libraries and then get the Katalon Studio Selenium WebDriver instance using the DriverFactory.getWebDriver() method. We then navigate to the Google homepage using the driver.get() method.

Once you have opened a web page using the Katalon Studio Selenium WebDriver, you can interact with the web page elements such as buttons, text fields, links, etc. using the various methods provided by Selenium. For example, the following code snippet shows how to enter text into a text field using the Katalon Studio Selenium WebDriver:

import com.kms.katalon.core.webui.driver.DriverFactory

import org.openqa.selenium.WebDriver

import org.openqa.selenium.WebElement

import org.openqa.selenium.B

// Get the Katalon Studio Selenium WebDriver instance

WebDriver driver = DriverFactory.getWebDriver()

// Navigate to the web page

driver.get(“https://www.google.com”)

// Find the search field element

WebElement searchField = driver.findElement(By.name(“q”))

// Enter text into the search field

searchField.sendKeys(“Katalon Studio Selenium WebDriver“)

With the above code, we first import the required libraries and get the Katalon Studio Selenium WebDriver instance. We then navigate to the Google homepage and find the search field element using the driver.findElement() method. Finally, we enter text into the search field using the search field.sendKeys() method.

Ways to simplify Selenium tests in Katalon Studio

Now that we understand how Selenium tests work in Katalon Studio, let’s discuss the ways to simplify Selenium tests in Katalon Studio.

Step 1: Use Katalon Recorder to Generate Test Cases

Katalon Recorder is a free browser extension that can record and export Selenium tests as Katalon Studio test cases. It is an excellent tool for beginners to learn Selenium and Katalon Studio. Here are the steps to generate test cases using Katalon Recorder:

Step 2: Use Katalon Studio Built-in Keywords

Katalon Studio provides built-in keywords that simplify the writing of Selenium tests. These keywords are pre-built functions that perform common actions such as clicking, typing, and selecting. You can use these keywords to create test cases without writing any code. Here is an example of using the built-in keywords:

Open the web application: WebUI.openBrowser(‘http://www.example.com’)

Type in the username: WebUI.setText(findTestObject(‘Page_Login/input_username’), ‘user’)

Type in the password: WebUI.setEncryptedText(findTestObject(‘Page_Login/input_password’), ‘password’)

Click on the login button: WebUI.click(findTestObject(‘Page_Login/button_login’))

Step 3: Use Custom Keywords

If you find yourself writing the same code repeatedly, you can create custom keywords to simplify your test cases. Custom keywords are reusable functions that perform specific actions. 

Here is an example of creating a custom keyword:

Click on a button using JavaScript:

@Keyword def clickButtonByJS(TestObject to) { WebDriver driver = DriverFactory.getWebDriver() WebElement element = WebUiCommonHelper.findWebElement(to, 30) JavascriptExecutor executor = ((JavascriptExecutor) driver) executor.executeScript(“arguments[0].click();”, element) }

Step 4: Use data-driven testing

Data-driven testing is a technique where you test your application with multiple sets of data. Katalon Studio provides built-in data-driven testing capabilities that simplify the creation of data-driven tests. 

Here is an example of using data-driven testing:

@Keyword def login(String username, String password) { WebUI.setText(findTestObject(‘Page_Login/input_username’), username) WebUI.setEncryptedText(findTestObject(‘Page_Login/input_password’), password) WebUI.click(findTestObject(‘Page_Login/button_login’)) } @ExcelSource(‘testdata.csv’) def testLogin(String username, String password) { WebUI.openBrowser(‘http://www.example.com’) login(username, password) // assert login was successful }

Conclusion

Simplifying Selenium tests in Katalon Studio is easy when you use the built-in keywords, create custom keywords, and use data-driven testing. These techniques can save you time and effort in creating and maintaining your test cases. With Katalon Studio, you can create automated tests quickly and easily, allowing you to focus on other critical aspects of your application.
