Running Chrome from Katalon (Linux)

[Richard_C_Davis]

I am running Katalon on a Debian Linux system (Debian 4.17.17-1 (2018-08-18) x86_64). All my tests are failing, apparently because Katalon is unable to launch Chrome. I suspect that katalon doesn’t know where to find Chrome. Can anyone tell me how to configure this?

Here is the command I’m using to run Katalon.

/home/userx/katalon/katalon --args -noSplash  -runMode=console -consoleLog -retry=0 -executionProfile="default" -browserType="Chrome (headless)" -projectPath="/home/userx/myproject/Tests/Tests.prj" -testSuitePath="Test Suites/List"

And here is an abbreviated version of the output I get:

You’ll notice two exceptions here. The first appears once, and the second is repeated for every test in the lines that I removed.

• 09-18-2018 05:34:36 PM - [ERROR] - java.lang.ExceptionInInitializerError
• 09-18-2018 05:34:36 PM - [ERROR] - java.lang.NoClassDefFoundError: Could not initialize class com.kms.katalon.core.webui.keyword.builtin.OpenBrowserKeyword

If you look at the test reports, you see these same exceptions.

Again, my suspicion is that katalon needs to be informed how to run chrome. I run chrome from “/usr/bin/google-chrome”. Is this what katalon expects? I should also say that I am running on a headless system. I’ve seen some posts recommending that I set a DISPLAY variable, and I’ve tried setting this variable to “:0.0” and “localhost:10.0” and similar values, but this doesn’t seem to make any difference.

Does anyone have any idea how to fix this?

Have a look at this post:

How to specify chrome browser binary path for chromedriver

Hi Katalon Support, One of our requirement is to be able to test our app with The Beta Chrome Browser version. While this could be achieved with following code in regular Java based frameworks, I am wondering how to achieve this with Katalon Studio? ChromeOptions optionsBeta = new ChromeOptions(); optionsBeta.setBinary(“path\\to\\chrome\\browser\\beta\\binary”); WebDriver driver = new ChromeDriver(optionsBeta); Requesting guidance on this topic. Thanks.

In your test case, you stop calling WebUI.openBrowser(). And you do the following:

System.setProperty("webdriver.chrome.driver", "/usr/bin/google-chrome")WebDriver driver = new ChromeDriver();// the magic lineDriverFactory.changeWebDriver(driver)WebUI.navigateToUrl('www.katalon.com')

[kazurayam]

Also you should change your commandline

cd /home/userx/katalonkatalon --args -noSplash -runMode=console -retry=0 -executionProfile="default" -browserType="Chrome (headless)" -projectPath="/home/userx/myproject/Tests/Tests.prj" -testSuitePath="Test Suites/List"

• you should not specify the “-consoleLog” option
• you need to change directory to the dir where the katalon binary is located

[Richard_C_Davis]

Thanks. Is there any way to do this while still calling “WebUI.openBrowser()”? I’m trying to check a few hundred tests written by students, and I can’t ask them to re-write their tests at this point.

[kazurayam]

I am not sure, but why not you try this?

System.setProperty("webdriver.chrome.driver", "/usr/bin/google-chrome")
WebUI.openBrowser('')
WebUI.navigateToUrl('www.katalon.com')

[Richard_C_Davis]

I’ve tried this out, and I’m able to run Chrome now.

I’m still not able to run tests, however. It probably has something to do with the fact that I’m trying to run on a system with no display. I have set the DISPLAY variable, but it doesn’t seem to have helped. Here’s a log excerpt.

Any other ideas? Thanks again.

Possibly you need Xvfb.

• Headless execution

• Xvfb failed to start in Jenkins for katalon automation test suite

[kazurayam]

Richard,

I suppose you are still hesitating to ask your students to change their code; insert a line:

System.setProperty("webdriver.chrome.driver", "/usr/bin/google-chrome")

There is an alternative method to set System Property. See the following post:

• Getting chromedriver.log when you run Record/Spy Web to investigate why KS failed to start Chrome

Edit %KATALON\_STUDIO\_INSTALLED_FOLDER%\\katalon.ini file on your Linux box.

[Richard_C_Davis]

I gave up on Chrome and started using Firefox instead. I still had the display problem, but using Xvfb fixed that. Now I’m up and running. Thanks a ton for your help!

Just for the record - there is now an official Docker image for Katalon Studio. If anyone has similar issues you can take a look.
