How to add a dynamic variable value inside a param field as a String in Karate?

Question

I have an API, wherein the Param field, I need to pass the current date as a string.

And param filter = 'ORDER_DATE:"2021-01-31"'

I am trying to pass the current date for the ORDER_DATE field form a java method:

* def todaysDate = helper.getTodaysDate()

And print todaysDate // Prints 2021-02-04

Now I need to pass this "todaysDate " valuein the param filter field.

Following what I have tried so far:

And param filter = 'ORDER_DATE:#(todaysDate )' 
And param filter = 'ORDER_DATE:<todaysDate>'

From example table value.

In Both cases, it printed "todaysDate " instead of its value "2021-02-04"

Answer 1

It is just JavaScript:

And param filter = 'ORDER_DATE:"' + todaysDate + '"'

This can improve in the 1.0 version BTW:

And param filter = `ORDER_DATE:"${todaysDate}"`
