Is there a way to use node js with karate ZIP edition [duplicate] - karate

Question

I'd like to use the 'faker' library to generate fake data in JSON file as below.
In karate-config.js, I do the following:
var faker = require('faker');
In sample.json:
{
'firstName': '#(faker.name.firstName)'
'city' : '#(faker.address.city)'
}
But I'm getting error like 'unable to find 'require' keyword in 'karate-config.js'
Please help on this.

Answer 1

Karate does not support NPM or the require keyword. For complex custom logic, the recommendation is to use Java interop.
My suggestion is you should find a Java library that does what "faker" does and integrate it.

Answer 2

First add the below dependency in your pom.xml
<dependency>
<groupId>com.github.javafaker</groupId>
<artifactId>javafaker</artifactId>
<version>1.0.2</version>
</dependency>
For the latest version of the dependency click here
Use the below code in karate-config.js:
config.faker = Java.type('com.github.javafaker.Faker');
In the feature file use the below code:
* def fakerObj = new faker()
* def fName = fakerObj.name().firstName()
* def lName = fakerObj.name().lastName()
* def mailId = fName+'.'+lName+'#test.com'
You could use the same in JSON body as follows:
"emailAddress":"#(mailId)",
"firstName":"#(fName)",
"lastName":"#(lName)",
"address":{
line1:"#(fakerObj.address().streetAddress())"}

Answer 3

As far as I know, karate only supports java based dependencies. So try to find a Java equivalent for your JS library.

Answer 4

thanks for your response and suggestion, tried below and working fine.
in karate-config.js:
var faker = Java.type('.FakerClass');
......
config.faker = faker;
in sample.json:
{ 'name': '#(faker.address.city)' }
