Can Karate generate multiple query parameters with the same name? - karate

Question

I need to pass multiple query parameters with the same name in a URL, but I am having problems getting it to work with Karate. In my case, the URL should look like this:
http://mytestapi.com/v1/orders?sort=order.orderNumber&sort=order.customer.name,DESC
Notice 2 query parameters named "sort". I attempted to create these query string parameters with Karate, but only the last "sort" parameter gets created in the query string. Here are the ways I tried to do this:
Given path 'v1/orders'
And param sort = 'order.orderNumber'
And param sort = 'order.customer.name,DESC'
And header Authorization = authInfo.token
And method get
Then status 200
And:
Given path 'v1/orders'
And params sort = { sort: 'order.orderNumber', sort: 'order.customer.name,DESC' }
And header Authorization = authInfo.token
And method get
Then status 200
And:
Given path 'v1/order?sort=order.orderNumber&sort=order.customer.name,DESC'
And header Authorization = authInfo.token
And method get
Then status 200
The first two ways provide the same query string result: ?sort=order.customer.name%2CDESC
The last example does not work because the ? get encoded, which was expected and explained in this post - Karate API Tests - Escaping '?' in the url in a feature file
It's clear that the second "sort" param is overriding the first and only one parameter is being added to the URL. I have gone through the Karate documentation, which is very good, but I have not found a way to add multiple parameters with the same name.
So, is there a way in Karate to set multiple URL query parameters with the same name?

Answer 1

Yes you can generate multiple query parameters with the same name in karate
All values of similar key should be provided in an array.
Given path 'v1/orders'
And params {"sort":["order.orderNumber","order.customer.name,DESC"]}
And header Authorization = authInfo.token
And method get
Then status 200
And for setting single parameter using param it will be like
And param sort = ["order.orderNumber","order.customer.name,DESC"]
