I made another Test Case as JUnit Test runner:

```auto
//import com.kms.katalon.core.testng.keyword.TestNGBuiltinKeywords as TestNGKW
import com.kazurayam.junit4ks.JUnitCustomKeywords
import com.lfilipovic.demo.SearchForEmployeeTest

JUnitCustomKeywords.runWithJUnitRunner(SearchForEmployeeTest.class)

```

This script uses `com.kazurayam.junit4ks.JUnitCustomKeywords` class instead of Katalon’s built-in keyword.

I ran this and got the following output:

```auto

```

Please find the following informative message in it:

```auto

java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; 

```

I am sure @lfilipovi is familiar with this error message. I believe he would be able to plan out how to fix this problem. The diagnostics really matter for [Software Quality](http://forum.katalon.com/t/webinar-software-quality-insights-a-deep-dive-into-katalons-state-of-quality-report-2023/86764), as we all know.
