Capture json response value in karate api - karate

How can I retrieve numeric value from json response in Karate API?
Here I want to retrieve 41651625424 this value in a variable as I have to pass this as input in another request body
{"items":{'41651625424': {itemCore: {partNumber: '1234567', productTitle: 'Karate API Testing'}}}}

Here you go. The trick is to convert this to a Java Map and then you have a lot of useful methods that do what you want:
* def response = {"items":{'41651625424': {itemCore: {partNumber: '1234567', productTitle: 'Karate API Testing'}}}}
* def map = karate.toBean(response.items, 'java.util.LinkedHashMap')
* def first = map.keySet().iterator().next()
* match first == '41651625424'

karate : handling soap response from a called feature file

first.feature
Given ur ''
def payload = read('')
request payload
soap action ''
value = /Envelope/Body/Response/Result/Num
print value # prints value correctly as expected
second.feature
Background:
*def fetch = read('first.feature')
*def data = call fetch
Scenario:
print data.response # prints the soap response in json format.
def res = data.response
print res["s:Envelope"][""]["s:Body"]["Response"][""]["Result"]["_"]["a:num']
first.feature works as expected ( response is in soap )
When I try to call this feature in another feature then the response is in json format.
I want to use a value from this response to pass it on to another request.
I had to use res["s:Envelope"]["_"]["s:Body"][][].. to get to that.
Is there a way to easily fetch a value from this response as we do in first.feature?
Please could anyone let me know how to achieve this.
Make this change:
* xml res = data.response
We will be improving this in the next version, it would be good if you can test the develop branch and confirm: https://github.com/intuit/karate/wiki/Developer-Guide

Sending a SOAP request with a file attachment [duplicate]

I have an endpoint who consumes Json with 2 attributes, like
{id='12344', data=byte_array}
so I've wrote a test
Feature: submitted request
Scenario: submitted request
* def convertToBytes =
"""
function(arg) {
var StreamUtils = Java.type('my.utils.StreamUtils');
// it reads stream and convert it to a byte array
return StreamUtils.getBytes(arg);
}
"""
Given url 'http://my-server/post'
And def image = convertToBytes(read('classpath:images/image_1.jpg'));
And request {id:1, data: "#(image)"}
When method POST
Then status 200
However is got an exception form karate without much details
ERROR com.intuit.karate - http request failed: [B cannot be cast to [Ljava.lang.Object;
Any hits how to submit byte arrays as a part of Json with karate?
I don't think you can do that. Either the whole request should be binary (byte-array) or you do a multi-part request, where binary is Base64 encoded. As far as I know you can't put binary inside JSON. There is something called Binary JSON though.
EDIT: after assuming that the byte[] has to be Base64 encoded:
Background:
* url demoBaseUrl
* def Base64 = Java.type('java.util.Base64')
Scenario: json with byte-array
Given path 'echo', 'binary'
And def encoded = Base64.encoder.encodeToString('hello'.bytes);
And request { message: 'hello', data: '#(encoded)' }
When method post
Then status 200
And def expected = Base64.encoder.encodeToString('world'.bytes);
And match response == { message: 'world', data: '#(expected)' }
I just added this test to the Karate demos, and it is working fine. Here is the commit.

How to pass the json list response of one feature file as parameter to another feature file

My requirement is, I want to pass the response of first feature file as input to second feature file. The first feature file response is a json list, so the expectation is second feature file should be called for each value of json list.
Feature:
Scenario: identify the reference account
* def initTestData = read('../inputData.feature')
* def accountData = $initTestData.response
* print “Account Details”+accountData // output of this is a json list [“SB987658”,”SB984345”]
* def reqRes = karate.call('../Request.feature', { accountData : accountData })
In Request.feature file we are constructing the url dynamically
Given url BaseUrl + '/account/'+'#(accountId)' - here am facing issue http://10.34.145.126/account/[“SB987658”,”SB984345”]
My requirement is Request.feature should be called for each value in ‘accountData’ Json list
I have tried:
* def resAccountList = karate.map(accountData, function(x){accountId.add(x) })
* def testcaseDetails = call read('../requests/scenarios.feature') resAccountList.accountId
Result is same, accountId got replaced as [“SB987658”,”SB984345”]
my I need to call Request.feature twice http://10.34.145.126/account/SB987658 http://10.34.145.126/account/SB984345 and use the response of each call to the subsequent feature file calls.
I think you have a mistake in karate.map() look at the below example:
* def array = ['SB987658', 'SB984345']
* def data = karate.map(array, function(x){ return { value: x } })
* def result = call read('called.feature') data
And called.feature is:
Feature:
Scenario:
Given url 'https://httpbin.org'
And path 'anything', value
When method get
Then status 200
Which makes 2 requests:
https://httpbin.org/anything/SB987658
https://httpbin.org/anything/SB984345

How to convert karate response to String type

I have a method in java that accepts String parameter. If I pass response which is karate in built variable. Java method gives exception as it is expecting double quotes in the stating.
* def JavaDemo = Java.type('karate.Utility.WriteJsonToFile')
Given url 'https://postman-echo.com/get?test=123'
When method get
Then status 200
* def sd1 = JavaDemo.writeJsonToFile(response, 'Response.json')
Please, please read the documentation. Here is the link to the section: Type Conversion
So you can do this:
* def JavaDemo = Java.type('karate.Utility.WriteJsonToFile')
Given url 'https://postman-echo.com/get?test=123'
When method get
Then status 200
* string response = response
* def sd1 = JavaDemo.writeJsonToFile(response, 'Response.json')
