Supercharge your RTP Validations with Groovy and RegEx

Master RTP Validations with Groovy and RegEx: A Step-by-Step Tutorial

Supercharge your RTP Validations with Groovy

One way to supercharge your RTP validation is to use RegEx.

RegEx or Regular Expressions can be very powerful in validating inputs. Personally, I am not an expert on Regular Expressions but check out the links below to get a fair idea.

Using RegEx for RTP Validation

Let’s start off with creating our script by declaring the RTP to take an email address as input, and then validating if the input is correct or not.

/*RTPS: {rtpAdminEmail}*/


// Create the message bundle
def mbUs = messageBundle (
 ["EMAIL":"The entered email address ({0}) is not valid. Please recheck email address and try again.",
 ] )
def mbl = messageBundleLoader(["en" : mbUs])


// validate rtpAdminEmail
validateRtp(rtps.rtpAdminEmail, """^([a-zA-Z0-9._%-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,6})*\$""", mbl, "EMAIL", rtps.rtpAdminEmail.EnteredValue)

Here’s what should happen.

Entering an incorrect email address

Validation error specifying that email address is incorrect

Let’s enter it correctly this time round

No error!

Once you get a hang of RegEx, you can create much more sophisticated and complex validations to ensure that the input provided is absolutely correct. And as you can see, it doesn’t take a lot of lines of code to do so!
