building dynamic urls in Karate and writing json output to a file

问题

How to build dynamic urls in Karate feature file? I tried something like this and didn't work.

Feature: PMS API Status Check
  Background:
    * url baseUrl
    * def spirit = 'SANRS'

  Scenario: Get guest details.
    Given path "'#(spirit)'/reservation/all"

Url is not evaluating to SANRS and goes as spirit. Also how do I change write the json response to a file. I see we can read the file using read(fileName) but did not see examples for writing to a file.

回答1:

The '#(foo)' notation applies only to JSON, XML or the right-hand-side of a match statement.

Please use it like a normal JS expression:

Given path spirit, 'reservation', 'all'

Please do look at the documentation and examples !

Yes, there is no example for writing to a file, because this is not recommended for tests. If you really want to do this - just write a custom Java or JavaScript function, refer to the docs for "Calling Java".
