Use different browser versions

In case you want Katalon Studio to use different versions besides the currently installed version, there are two ways to do it.

  1. You can use custom keywords.
    To use this method, the browser instances you wish to use should be installed on your machine first.
  2. Create a custom keyword to open the browser. Press Ctrl + Shift + O to automatically import necessary packages. To learn more about creating a custom keyword, you can refer to this document here: Introduction to Custom Keyword.

    import com.kms.katalon.core.webui.driver.DriverFactory
    public class WebUICustomKeywords {
    def openFirefoxBrowser(String firefoxPath, String firefoxDriver) {

    //Set path to Firefox version
    System.setProperty("webdriver.firefox.bin", firefoxPath)

    //Set path to Firefox driver: \configuration\resources\drivers\firefox_win64\geckodriver.exe System.setProperty("webdriver.gecko.driver", firefoxDriver)
    WebDriver driver = new FirefoxDriver()

    def openChromeBrowser(String chromeDriverPath, String chromePath) {

    //Set path to chromedriver driver: \configuration\resources\drivers\chrome_win32\chromedriver.exe System.setProperty("", chromeDriverPath)
    ChromeOptions options = new ChromeOptions()

    //Set path to Chrome binary options.setBinary(chromePath)
    WebDriver driver = new ChromeDriver(options) DriverFactory.changeWebDriver(driver)
  3. In a test case, use the newly created keyword.

    CustomKeywords.'com.example.WebUICustomKeywords.openFirefoxBrowser'('C:\\Program Files\\Mozilla Firefox 52\\firefox.exe', 'C:\\5.4\\Katalon Studio Windows 64\\configuration\\resources\\drivers\\firefox_win64\\geckodriver.exe')

You can also downgrade browser version.
If you want to use a very old version of your current browser, you may need to downgrade or upgrade browser drivers as well as Selenium WebDriver, you can refer to this document here: Update or Downgrade WebDrivers
