Straight forward approach to parallelism in Katalon Studio is to run multiple Test Suites in a Test Suite Collection.

> **[Test Suite Collection](https://docs.katalon.com/katalon-studio/docs/test-suite-collection.html)**

If you have 2 Test Suites to run parallel mode, each of them will run in separated OS processes = Java VM instances (not Threads)

??? I do not understand your question.

My WebDriverFactory4ks works on Katalon Studio Free version. It does not require KSE, KRE license. Just download the jar from [Releases · kazurayam/WebDriverFactory4ks · GitHub](https://github.com/kazurayam/WebDriverFactory4ks/releases) and put it into `<projectDir>/Drivers` directory.

Hello @kazurayam, i already performed what you have instructed.  
However, i’m using the script below to start a chrome profile, however what is missing is that how to modify it to execute ii with headless mode? I want to modify only the script below to do that:

```
public class open_dedicated_chrome_profile {

/**
 * Open dedicated enroll chrome profile
 */
@Keyword
def openBrowser(String identityType) {

	WebDriver driver = WebDriverFactory.newWebDriver(DriverFactory.getExecutedBrowser(), identityType) // THIS IS THE MAGIC
	assert driver != null
	DriverFactory.changeWebDriver(driver)	// Do not forget this

	WebUI.comment("${DriverFactory.getExecutedBrowser()} has been opened with ${identityType}")

	KeywordUtil.markPassed('Dedicated chrome opened successfully')
}

```

You do not have to modify your `open_dedicated_chrome_profile.openBrowser()` at all.

In Katalon Studio GUI, you want to choose Chrome (headless).

`DriverFactory.getExecutedBrowser()` will return a String “HEADLESS\_DRIVER”. This will instruct `WebDriverFactory.newWebDriver("HEADLESS_DRIVER", identityType)` to start Chrome Headless using the specified user profile.

I did the test, however, when i choose Chrome, my test run successfully but not when i choose Chrome(Headless). I believed that in headless mode, test is run as if in incognito mode.

My test passed when i choose only Chrome from the list but not when choosing the chrome-headless.

With Chrome:

It mention that a web element was not found, but that’s not the issue.  
In fact, when i run my test with Chrome, it pass because there is an existing enrollment in the profile chrome browser, but in headless mode, i believe that cookies, my enrollment does not exist. See snapshot when failed:

 ![image](https://europe1.discourse-cdn.com/katalon/original/3X/a/6/a6a5fd01fb8afed90f24411cc107e6a2f3aa5996.png)

The above error is displayed when there is no enrollment.

I have no idea how your problem “NAV06 You must enroll your browser to authenticate” comes up.

I think i can do nothing about it.
