Running two test cases simultaneously - Ping Pong Test Case

Ibus · September 4, 2019, 8:29am

well … here a proof of concept.
First, I made two testcases, ‘TC ping’ and ‘TC pong’. Both of them have a public variable, ‘count’, of type number with initial value 0 (use the Variables tab to define them). See attached pic:

ping_pong

Next, for fun, let’s make a custom ‘test’ package with two keywords, ping and pong, which only prints the received count value <<< you can put your scripts there:

package test

import com.kms.katalon.core.annotation.Keyword

public class pp {
	@Keyword
	def ping(count){
		println("ping! ${count}")
	}
	
	@Keyword
	def pong(count){
		println("pong! ${count}")
	}
}

Now, the tescases looks as follows:

in ping we check if we reached the iteration limit, increase the count, do the ping and call the pong testcase. we bind the count variable to save the actual value.

import static com.kms.katalon.core.testcase.TestCaseFactory.findTestCase
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

if (count < 5) {
	count ++
	CustomKeywords.'test.pp.ping'(count)
	WebUI.callTestCase(findTestCase('TC pong'), ["count":count])
} else {
	println('done!')
}

in pong, we have to make sure that the case is called by the first one, so we check the count to not be zero, do the pong and call back the ping testcase. we bind again the count variable to pass back the actual value.

import static com.kms.katalon.core.testcase.TestCaseFactory.findTestCase
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

if (count != 0) {
	CustomKeywords.'test.pp.pong'(count)
	WebUI.callTestCase(findTestCase('TC ping'), ["count":count])
} else {
	println('dont start the loop from this testcase!')
}

and we start the loop by running ‘TC ping’ (attempting to start the loop with 'TC pong" will just end quickly)
The Log View will be funny, since each case will appear under the previous one, as a tree. I wonder how will look for 100 iterations

Here is the console output:

Of-course, you can do the ping-pong other ways, e.g from a single testcase and making the keywords to call each-other, to avoid the nested log view result … or other solution i don’t have in mind right now.
Hope it helped. Have fun!

Warning! this method is most probably resource hungry, since each iteration will add again the objects in memory. Use it with caution!
