Can we call a scenario from one feature in another using karate? - karate

We have a feature A with several scenarios. And we need one scenario from that file. Can we call it in our feature B?

No. You need to extract that Scenario into a separate*.feature file and then re-use it using the call keyword.
EDIT: Karate 0.9.0 onwards will support being able to call by tag as follows:
* def result = call read('some.feature#tagname')

To illustrate the answer from Karate-inventor Peter Thomas with an example:
Given a feature-file some.feature with multiple scenarios tagged by a tag-decorator:
#tagname
Scenario: A, base case that shares results to e.g. B
// given, when, then ... and share result in a map with keyword `uri`
* def uri = responseHeaders['Location'][0]
#anotherTag
Scenario: X, base case that shares results to e.g. B
// given, when, then ... and share result in a map with keyword `createdResourceId`
* def createdResourceId = $.id
In another feature we can call a specific scenario from that feature by its tag, e.g. tagname:
Scenario: B, another case reusing some results of A
* def result = call read('some.feature#tagname')
* print "given result of A is: $result"
Given path result.uri + '/update'

Karate : How to refer or read variable in Examples section which is defined in Scenario Outline

In karate framework, I am trying refer variable in Examples section which is defined in Scenario Outline. Below is the code snippet of feature file.
Scenario Outline:
* print __row
* def data = read('test.csv')
* def selected = 'TRUE'
* def fun = function(x){ return x.Status == selected }
* def filtered = karate.filter(data, fun)
* print filtered
Examples:
| filtered |
After I execute this, getting below error.
*js failed:
org.graalvm.polyglot.PolyglotException: ReferenceError: "filtered" is not defined*
Can any one please let me know how this can be achieved?
The Scenario Outline is the last thing to take control so you need to understand the flow. Please refer to this answer: https://stackoverflow.com/a/75155712/143475
Maybe you should get a normal Scenario Outline to work before trying advanced things. Take some time to read the documentation: https://github.com/karatelabs/karate#data-driven-tests

Karate Gatling report - is it possible to avoid url based aggregation?

I just started to use Karate Gatling for performance tests and facing following problem:
I have a call for the search and would like to evaluate different types of search depending on the parameter e.G. https://example.com/search/facetedSearch
'*'
'keyword1'
'keyword1, keyword2' etc.
The feature file looks something like this:
#performance
Feature: Search
Background:
* url 'https://example.com/'
Scenario Outline: Search -> Simple search for a single word
Given path '/search/facetedSearch'
And param facetedSearchAdditionalFilter[searchAreaID] = -1
And param facetedSearchAdditionalFilter[searchKey] = '<SearchTermSimple>'
When method post
Then status 200
And assert iNumHits >= iNumHitsExpected
Examples:
| read('../testData/performanceTestData.csv') |
Scenario: Search -> Simple search for *
Given path '/search/facetedSearch'
And param facetedSearchAdditionalFilter[searchAreaID] = -1
And param facetedSearchAdditionalFilter[searchKey] = '*'
When method post
Then status 200
And assert iNumHits >= iNumHitsExpected
Scenario Outline: Search -> Search for multiple words
Given path '/search/facetedSearch'
And param facetedSearchAdditionalFilter[searchAreaID] = -1
And param facetedSearchAdditionalFilter[searchKey] = '<SearchTermMultiple>'
When method post
Then status 200
And assert iNumHits >= iNumHitsExpected
Examples:
| read('../testData/performanceTestData.csv') |
I would like to evaluate different types of search separately, as the performance is significantly different. What gatling does - it aggregates all different types of search in one result - "POST /search/facetedSearch".
Is there a possibility to let evaluate every type of search individually in one run?
Thanks in advance,
Sergej
Yes, refer the docs on using a custom nameResolver: https://github.com/karatelabs/karate/tree/master/karate-gatling#nameresolver
For your case you should be able to call req.getParam("facetedSearchAdditionalFilter[searchKey]")[0] or something similar. Or you could choose to use an additional header.

How to generate more than one random UUID and use in scenario outline examples in karate [duplicate]

This question already has an answer here:
How to use cucumber table when it is code driven
(1 answer)
Closed 1 year ago.
I am new to Karate API, pardon me for the mistakes if any.
I want to generate multiple random UUID and then use them in scenario outline examples
Example:
Background:
def UUID = function() {return java.util.UUID.randomUUID() + ''}
Scenario outline: to do post call
Given url 'http://localhost:8080'
def UID = UUID()
print UID
And request {CID:"", name :""}
When method POST
Then status 201
Examples:
|CID| name|
|UID1| james|
|UID2| rahul|
Here in above 'Examples' I wanted to use randomly generated UUID in data table of examples so that I can run multiple scenarios for UUID with one POST API call.
First question: How can I generate multiple random UUID ?
Second question: once multiple UUID gets generated how can i call in scenario outline examples and use them?
Can anyone suggest me on this?
Please try running the following simple example.
Feature:
Background:
* def uuid = function(){ return java.util.UUID.randomUUID() + '' }
Scenario Outline:
* url 'https://httpbin.org/anything'
* param foo = uuid()
* request { item: '#(item)' }
* method post
Examples:
| item |
| first |
| second |
It will make 2 requests, and each request will use a different param called "foo" and the URL will be like this:
https://httpbin.org/anything?foo=c1b6ab3d-5952-413b-827c-d9579a0a93b6
So it is simple. Think of the Examples: as like a "loop". Each time the Scenario Outline runs, we are calling the uuid() function again, which will return a different, random value.

Is it possible to generate dynamic variable names in Karate? [duplicate]

This question already has an answer here:
How to set dynamic value as a key to json string in request
(1 answer)
Closed 1 year ago.
I am making a REST API call which returns a response like this
{"id":"726295ab-d6bc-4f09-8cb7-6f6f54fc9364", "name":"Customer Data"}
I create 5 objects like this and I want to store the ids of all the 5 objects from response in 5 different variables.
I tried using something like
* def catID_<categoryName> = $.id
and provided the name of the object in the Examples section. It works fine most of the times except when the name has spaces in it.
no step-definition method match found for: * def catID_Customer Data = $.id
Is it possible to do something like this?
* def catName = replace all spaces in the name with _
* def #(catName)_id = $.id
or is there a better way to achieve this?
You seem to be doing things Karate is not designed to do, so by default please assume that this is not supported.
Most likely, adding keys to a JSON object is a more elegant approach instead of trying to dynamically hack def. For example:
* def variables = {}
* variables['<someDynamicName>'] = $.id
# then later
* print variables['actual name']
Also note that the '< and >' are not required: https://github.com/karatelabs/karate#scenario-outline-enhancements
