How to iterate a Global Variable on every run?


#1

Hi guys, I wonder to know-how increase the value inside my global variable “Email”. Now I’m running my test suit to create the entire user login, with the same Gmail account to receive the confirmation emails.
For example:
Rodrigo+realtor+1@gmail.com
Rodrigo+realtor+2@gmail.com
.
.
.
Rodrigo+realtor+n@gmail.com

But my problem is that I have to change this ‘n’ manually, Is any way to increase this value inside the variable from the @SetupTestCase or @SetUp?
(but only increase the value on the profile I choose to execute)

PD: I’m new with automation so I’m open to hearing new ways to automate this task. I thought to use this variable as a TestData object but that is when you have to create a bunch of users on the same Run, right?


#3

Guys @Russ_Thomas @Brandon_Hein, I didn’t find on the forum any post related to this. Could you give a hand here please?

I just tried the following in the SUIT script mode:

@SetUp(skipped = false)
String email = GlobalVariable.RealtorEmail
String newEmail= “Rodrigo+realtor+” + (Integer.parseInt(GlobalVariable.RealtorEmail.substring(17,email.length()))+1) + "@gmail.com";
GlobalVariable.RealtorEmail= newEmail

@rodrigocalabretta

It seems like what you want, does it work ? What’s the test script and the consoel output ?


#5

Hi @ThanhTo, not at all. Not sure if this is the way to do it.

Also when I store the global variable into the string variable “email” I think I’m storing only the name of that variable and not his string value

This is my log after run that thing :persevere::

If you want to automate this how would you do it


#6

@rodrigocalabretta

Please post the console log on the Console Tab, it has more information regarding why it fails.


#7

@ThanhTo

The value of RealtorEmail variable is "lemonbrewqa+realtor49@gmail.com"


#8

@rodrigocalabretta

Please create a copy of your project, download the latest version and execute on the copied project. I think in the latest version we’ve logged more elaborated error logs.

Also, does any of the input data is 49@gmail.com ? You use substring(19, email.length()) so there might be an offset problem.


#9

@ThanhTo I could do it! Check my code:

def setUp() {
String number = GlobalVariable.RealtorEmail.split(‘realtor’)[1].substring(0,2).trim()
Integer numberInt = Integer.parseInt(number)+1
String newEmail1= “lemonbrewqa+realtor” + numberInt.toString() + "@gmail.com";
GlobalVariable.RealtorEmail= newEmail1
}

I’m increasing that number from 49 to 50, but my problem is the last line where I want to store those 50, so in the next Race increase to 51 is not working. Is possible to reassign a new value, right?


#10

I tried and it is possible, here’s my set up.

A profile contains a Number variable called globalNum

Test case:

def globalVar = GlobalVariable.globalNum

println globalVar;

Test Suite contains 6 instances of Test case. In the Script tab of the Test suite, I have this:

/**
 * Run before each test case starts.
 */
@SetupTestCase(skipped = false) // Please change skipped to be false to activate this method.
def setupTestCase() {
	GlobalVariable.globalNum = GlobalVariable.globalNum + 1;
}

The console log prints

Please try the simple scenario of incrementing a number in global variable, then gradually switch to concatenating it with a string.


#11

Yeap I follow you, but that Number variable I set on 0 in my Execution profile is still on 0 after runs end. Your globalVar after increasing 6 times, in your profile execution that variable was reassigned to 6?


#12

@rodrigocalabretta

Okay I think I finally catch what you mean. Katalon has no way to mutate the global variable permanently, only in the context of an execution does the change effect. Please refer to this:

and see if it makes more sense.


#13

Wow thanks for that approach… It’s more complex than I thought, but let me know if I understand correctly. I can set in the TearDown function, my code to increase the new value of the variable (which is now working) and use this keyword to update my current execution profile with the new value increased, right?


#14

Yes, that is correct. Please try and see if it works for you.


#15

@ThanhTo thanks mate you made my day!

It’s working and increasing perfectly well

My Code
@TearDown(skipped = false) // Please change skipped to be false to activate this method.
def tearDown() {
	//Put your code here.
	String number = GlobalVariable.RealtorEmail.split('realtor')[1].substring(0,2).trim()
	Integer numberInt = Integer.parseInt(number)+1
	String newEmail1= "lemonbrewqa+realtor" + numberInt.toString() + "@gmail.com";
	
	'Assign new value in real time (not updates the profile)'
	//GlobalVariable.RealtorEmail=newEmail1
	
	'Assign new value in real time (updates the profile with new value)'
	CustomKeywords.'lemonbrew.GlobalVariableUpdater.updatePermanently'("Agent", "RealtorEmail" , newEmail1)
}

A detail commented by @Marek_Melocik is that ** Katalon does not look for updates in the execution profile ** until the executions are finished. For me it is not a problem because I configured this code in TearDown and it works, the only thing that was freaking me out was that the profile wasn’t updating automatically in the IDE (but is updating in the folder file). To see that the value increased, you have to close the profile tab and open it again after Katalon finishes loading and sending the reports.

Thanks again for your help!!


#16

I just want to add a new update for this solution with the following improvement:

This improves for any string email so you don’t need to type it and concatenate (the code split the string by the @, so must be that character)

Script
String number = GlobalVariable.RealtorEmail.split('@')[0].replaceAll("[a-z, +]", "")
	String emailP1 = GlobalVariable.RealtorEmail.split('@')[0].replaceAll("[0-9]", "")
	String emailP2 = GlobalVariable.RealtorEmail.split('@')[1]
	if (number != ""){
		number = Integer.parseInt(number)+1
	}
	else{
		number = 1
	}
	String nextEmail= emailP1 + number.toString() + "@" + emailP2
		
	'Assign new value in real time (not updates the profile)'
	//GlobalVariable.RealtorEmail=nextEmail
	
	'Assign new value in real time (updates the profile with new value)'
	CustomKeywords.'lemonbrew.GlobalVariableUpdater.updatePermanently'("Agent", "RealtorEmail" , nextEmail)

Import the custom keyword “GlobalVariableUpdater.updatePermanently” above from this link How to update GlobalVariable permanently

Here I adapt my script logic above creating this new GlobalVariableUpdater.increaseEmailVariablecustom keyboard below using the custom keyboards created by @Marek_Melocik

NOTE: If you use this any of this keywords in a test Case you probably have an error after every test because the project doesn’t refresh all the files like when a Test Suite ends, so take that in mind. Maybe you can try to refresh it manually going to Project > Refresh (Crtl+F5)
