Known limitation​

  • Browser hang issue occurs when launching Chrome version 135 and above in Katalon Studio. From Chrome 136 onward, security restrictions prevent using the default profile folder. Refer to the following documentation for the workaround: Katalon Compact Utility for Katalon Studio.

Version 10.2.2​

Release date: June 18, 2025

Fixes​

  • Remove Chrome for Testing for recording and execution. Katalon Studio now reverts to using Chrome as usual.
  • Added the argument -disable-features=DisableLoadExtensionCommandLineSwitch in Desired Capabilities to address the issues with Chrome 137.

Version 10.2.1​

Release date: May 31, 2025

Fix​

  • Katalon Studio’s Web Recorder failed to launch on Chrome version 137 due to changes in browser automation protocols, including the removal of the --load-extension flag.

    Starting with this version, Katalon Studio uses Selenium Manager instead of Web Driver Manager for Chrome browser, enabling support for Chrome for Testing. During both recording and execution, Katalon automatically downloads the compatible Chrome version the latest version (or specified version) of Chrome for Testing, restoring full functionality with Chrome v137 and later.

    On the first launch, Katalon Studio will download Chrome for Testing, so starting the browser may take longer.

    To change this behavior, launch Chrome with binary desired capability specifying the desired Chrome binary location and add the following args as shown in the screenshot below:

      --disable-features=DisableLoadExtensionCommandLineSwitch
    Disable Chrome extension

    You can also specify a Chrome binary location using the binary capability to control which version of Chrome for Testing is launched.

    note

    For detailed steps on setting up your desired capabilities, see: Set up Desired Capabilities for WebUI Testing in Katalon Studio

Known Issue​

  • In some secured or network-restricted environments, users may be restricted from downloading the WebDriver due to network or firewall policies. To ensure proper functionality, your IT team will need to whitelist the following URLs:
    • https://storage.googleapis.com
    • https://googlechromelabs.github.io/chrome-for-testing/known-good-versions-with-downloads.json

Changes​

  • Application names updated:

    • Free Edition: Katalon Studio

    • Enterprise Edition: Katalon Studio Enterprise

    • Apple Silicon Chip: Removed the Arm64 suffix.

  • Updated MobileBy to AppiumBy class.

  • Adjusted offline license and On-Premises flow where login dialog is triggered.

  • Ordered test cases alphabetically in Dynamic Test Suite.

  • Any test case referencing SmartWaitWebDriver will encounter a runtime error as the class has been removed.

  • Updated WebUI.setViewPortSize to align with WebUI.getViewportWidth and WebUI.getViewportHeight, ensuring consistent viewport size results.

  • The licenseServer.properties file has been removed as of version 10.0.0.

  • Corrected the behavior of setViewportSize to ensure that the values returned by getViewportWidth and getViewportHeight are consistent with the dimensions set by setViewportSize. Note: When using the --window-size in Desired Capabilities, getViewportWidth and getViewportHeight may return different values because this setting adjusts the window size, not the viewport size.

  • Refactored DriverFactory. Moved getChromeDriverPath to ChromeDriverUtil. To use getChromeDriverPath(), add import com.kms.katalon.core.webui.driver.chrome and retrieve the path with:
    String chromeDriverPath = ChromeDriverUtil.getChromeDriverPath()
  • Based on Selenium 4 documentation, test capabilities that are not structured to be W3C compliant may prevent a session from starting. The following list outlines the W3C WebDriver standard capabilities:

    • browserName

    • browserVersion (replaces version)

    • platformName (replaces platform)

    • acceptInsecureCerts

    • pageLoadStrategy

    • proxy

    • timeouts

    • unhandledPromptBehavior

  • Any capability not listed above must include a vendor prefix. For example, when running on TestCloud, using app and deviceName in desired capabilities can disrupt the session creation process. The correct format for custom capabilities requires a vendor prefix, such as katalon:option for Katalon.

Known limitations​

  • Katalon Compact Utility (KCU) is not supported with BiDi due to a Chrome limitation with profile management.

  • When using BiDi, a BiDi-CDP Mapper tab opens to start the connection.

  • BiDi does not work with Incognito mode in Chrome and Edge Chromium. Attempting to open a session in Incognito mode with BiDi enabled causes the browser session to open briefly and then close automatically. This issue affects: Chrome, Edge Chromium, and Chrome Headless. Workaround:

    • Set webSocketUrl = false in desired capabilities to disable BiDi if Incognito mode is required.

  • BiDi does not work with custom profiles in Chrome and Edge Chromium. Attempting to open a session with a custom profile and BiDi enabled causes the session to fail with an initialization error.

  • Docker image on linux/arm64 supports Firefox version 129 instead of the latest version 131.

  • Removal of AbstractEventListener, EventFiringWebDriver, and WebDriverEventListener in Selenium. Follow Selenium documentation to migrate test scripts that use these classes: Removal of AbstractEventListener + EventFiringWebDriver + WebDriverEventListener.

  • Simple dialogs (alert/prompt) handler behavior: The unhandledPromptBehavior capability, which defaults to "dismiss and notify" per W3C standards, dismisses simple dialogs automatically. Workaround:

    • Set unhandledPromptBehavior to ignore so that you can handle dialogs manually.

  • Install dependencies: Node installation failed during dependency setup, including manual installation (without Katalon Studio). A warning may appear stating, The post-install step did not complete successfully. Workaround:
