Steps to follow,

Note - Make sure you are executing tests on a valid BrowserStack remote URL and have set up custom execution capabilities with minimum details - project, build and browser version.

1.In Katalon, declare three variables in a profile file as below.

sessionid as String

bsUserName as String - Assign BrowserStack account login username [ use the same variable name ]

bsPassword as String - Assign BrowserStack account login password [ use the same variable name ]

2.Insert below line of code in each Katalon test cases after 'Open Browser' step.

GlobalVariable.sessionid = CustomKeywords.'com.testwithhari.katalon.plugins.Browserstack.getCurrentTestRunSessionID'()

3.Copy and Paste below method in Listener Class.

 @AfterTestCase
 def sampleAfterTestCase(TestCaseContext testCaseContext) {
 if(testCaseContext.getTestCaseStatus() != 'FAILED') {
 CustomKeywords.'com.testwithhari.katalon.plugins.Browserstack.updateTestName'(GlobalVariable.sessionid, testCaseContext.getTestCaseId())
 CustomKeywords.'com.testwithhari.katalon.plugins.Browserstack.updateTestStatusAndReason'(GlobalVariable.sessionid, "PASSED", "Testcase is PASSED")
          }
          else {
  CustomKeywords.'com.testwithhari.katalon.plugins.Browserstack.updateTestName'(GlobalVariable.sessionid, testCaseContext.getTestCaseId())
  CustomKeywords.'com.testwithhari.katalon.plugins.Browserstack.updateTestStatusAndReason'(GlobalVariable.sessionid, "Failed", "Testcase is FAILED")
              }
              }

4.Execute test cases from Katalon and check test names and statuses updated accordingly in BrowserStack
