Katalon Studio Tutorial

Introduction to Katalon Studio

Katalon Studio is a powerful test automation tool that supports web, mobile, and API testing. It is built on top of the Selenium and Appium frameworks and integrates various features to simplify the test automation process. Katalon Studio offers an intuitive interface, rich capabilities, and extensive support for testing applications across different platforms.

Installation

To get started with Katalon Studio, you need to download and install it on your machine. Follow these steps:

  1. Go to the Katalon Studio download page.
  2. Select the version compatible with your operating system (Windows, macOS, or Linux).
  3. Download the installer and run it to complete the installation.
  4. Once installed, open Katalon Studio and create a new project.

Creating Your First Test Case

After setting up Katalon Studio, you can start creating test cases. Here’s how to create your first test case:

  1. Open Katalon Studio.
  2. Create a new project by selecting File > New > Project.
  3. Enter the project name and click OK.
  4. In the left sidebar, right-click on Test Cases and select New.
  5. Give your test case a name. For example, LoginTest.
  6. Click on the Record button to start recording your actions.
Example: If you are testing a login feature, you would record entering the username and password, and clicking the login button.

Writing Test Scripts

Katalon Studio allows you to write test scripts in Groovy, a powerful scripting language. You can switch to the script view from the manual view. Here’s a simple example of a test script:

import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

WebUI.openBrowser('https://example.com')
WebUI.setText(findTestObject('Object Repository/Page_Login/input_username'), 'user')
WebUI.setText(findTestObject('Object Repository/Page_Login/input_password'), 'password')
WebUI.click(findTestObject('Object Repository/Page_Login/button_login'))
WebUI.closeBrowser()

This script opens a web browser, navigates to a login page, fills in the username and password, clicks the login button, and then closes the browser.

Running Test Cases

To run your test case, simply click the Run button located in the toolbar. You can choose to run the test case on different browsers by selecting the browser from the dropdown menu next to the Run button.

Output:
Test case execution results will be displayed in the log view. You can see if it passed or failed, along with any error messages.

Integrating with CI/CD

Katalon Studio can be integrated with Continuous Integration/Continuous Deployment (CI/CD) tools like Jenkins, Azure DevOps, and GitLab. This allows for automated test execution as part of the build process.

To integrate with Jenkins:

  1. Install the Katalon Studio command-line tool.
  2. Create a new Jenkins job and configure the build step to execute Katalon tests using the command line.
  3. Use the command: katalon -noSplash -runMode=console -projectPath="path/to/your/project" -testSuitePath="Test Suites/YourTestSuite" -executionProfile="default" -browserType="Chrome".

Conclusion

Katalon Studio is a versatile and user-friendly tool for automating tests across different platforms. This tutorial covered the basics of installation, creating test cases, writing scripts, running tests, and integrating with CI/CD tools. With Katalon Studio, you can streamline your testing process and improve your software quality.
