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.

Karate: Is there a way to pass variable as string in scenario outline and examples table [duplicate]
(1 answer)
Closed 1 year ago.
I am running API execution using Scenario Outline and csv and want to edit header in the below format where i need to change the requestorid each and every time for the execution.
If the headers uses below format and saved in .js and tried saving it in .json file:
"ID-HEADERS" :"{ 'requestorId': '1111', 'authMethod': 'basic'}"
And used below lines to edit the header which is not working:
function() {
var fun = karate.read(headersFilePath + 'headers.js');
var res = fun();
res['ID-HEADERS.requestorId'] = requestorId;
return res;
}
If you just need to set one header don't complicate it with JS:
Scenario Outline:
* url 'https://httpbin.org/anything'
* header foo = bar
* method get
Examples:
| bar |
| one |
| two |
Try it, and see the logs and HTML report. And read the documentation also.
We're using Karate for backend testing of a microservice. I'd like to be able to make N calls to the backend API, where N is configurable as a number without having to do ugly things.
This was my first approach:
Given url baseUrl
And headers HEADERS
When method get
Then status 200
Given url baseUrl
And headers HEADERS
When method get
Then status 200
Given url baseUrl
And headers HEADERS
When method get
Then status 200
(Just repeating the call) It works, but obviously does not scale well (imagine 1000 of these).
Next approach was a bit better - I put the call in a separate feature and used the https://github.com/intuit/karate#data-driven-features approach:
* table jwts
| headers |
| HEADERS |
| HEADERS |
| HEADERS |
| HEADERS |
| HEADERS |
* def result = call read('call-once.feature') jwts
Slightly better but still does not scale. We also tried varieties of karate.repeat() which seems like the most natural approach, but had trouble with the syntax. None of the examples I could find had an API call inside of a for-each.
* def callFunction = function (HEADERS) { read('call-putaway-once.feature'); { HEADERS: '#(HEADERS)'} }
* def result = karate.repeat(5, callFunction)
But couldn't get any varieties of that working.
Can anyone provide an example of how to repeat the same exact Karate lines N times? I'm really looking for something like:
for (int i = 0; i < numTimes; i++) {
Given url baseUrl
And headers HEADERS
When method get
Then status 200
}
(Or functionally equivalent).
Thanks!
Here you go. First, the second called.feature:
#ignore
Feature:
Scenario:
Given url 'http://httpbin.org'
And path 'headers'
And header X-Karate = count
When method get
Then status 200
And now you can do this in your first feature:
* def fun = function(x){ return { count: x } }
* def data = karate.repeat(5, fun)
* call read('called.feature') data
P.S. by the way search the readme for "polling", there is an example of an API call in a loop: polling.feature
Karate almost have a feature to do this : retry until.
This feature doesn't repeat "n" time, but repeat until a condition is not validate
Example here : polling.feature
For a simple request it's seems like :
Given url baseUrl
And headers HEADERS
And retry until responseStatus == 200
When method get
While using data-driven feature in Karate framework, I see the generated report just show the title as configured in Scenario Outline NOT attached the value using in Example table. It causes the Tester confuse which data is using, and take time to expand each scenarios to know which data is using; so I want the report can pass variable into the title - Scenario/Scenario Outline. Please take a look at the example below.
E.g.
Feature: Login Feature
Background:
* configure headers = { 'Webapp-Version': '1.0.0'}
Scenario Outline: As a <description> user, I want to get the corresponding response_code <status_code>
Given def path = 'classpath:features/Authentication/authentication.feature'
And def signIn = call read(path) {username: '<username>', password: '1234567890'}
Then match signIn.status == <status_code>
Examples:
|username | status_code| description |
|test#gmail.com | 200 | valid user |
|null | 400 | invalid user|
My expected result, the generated report should fill the value on table for field "status code" and "description" fields.
-> As a valid user user, I want to get the corresponding response_code 200.
Please share your ideas and comments on it.
Thanks,
Learn.
Not supported. Just use the print syntax and you will see it in the report.
EDIT: okay this will be possible in the next version: https://github.com/intuit/karate/issues/553

Check 2 differents status with Karate
(1 answer)
Closed 1 year ago.
I'm doing data driven test with Karate, and met a block issue. The REST API response body is in different structure with different status. For example, when the status is 200, the response body is JSON array. When the status is 4** and 5***, the response body either is string or blank. I hope to check the response conditionally using the blow code. But seems it doesn't work.
"* eval if (verInfo.statusCode == 200) (match each response contains any verInfo.respBody) //verInfo.statusCode and verInfo.respBody is from the test data(DDT)
* eval if (verInfo.statusCode != 200) match response contains verInfo.respBody"
First, you cannot mix Karate script and JavaScript like this.
Second I suggest you use the responseStatus built-in variable. I also suggest using proper data-driven approaches instead of over-engineering your tests with conditional logic.
So you can do this, (and there are many other ways if you go through the docs and examples):
Scenario Outline:
Given url 'http://foo.bar'
And request <req>
When method post
Then match responseStatus == <code>
And match response == <body>
Examples:
| req | code | body |
| 'a' | 200 | 'foo' |
| 'b' | 400 | '' |
In my feature I have:
* def loc = responseHeaders['location'][10]
* def id = loc.substring(loc.lastIndexOf('/') + 1)
And I would like to use id in scenario outline examples:
Scenario Outline: fkdfslqknfd
Given url 'foo.com'
And path <bar>
When method get
......
Examples:
|bar |
|(id)|
|"id"|
|'id'|
|id |> The last example is ok.
But instead of receiving 'foo.com/13' (assuming that id is 13) I have 'foo.com/id'. I tried with #, but it doesn't work. How I can replace this id? I need to test this id put in String format. Thanks
At least within JSON parameter, it was working for me
Examples:
| request_body |
| {username: '#(email)', password: '#(password)'} |
This is a known limitation of Cucumber, that the Examples cannot be dynamic. Refer to this last paragraph of the documentation: https://github.com/intuit/karate#the-karate-way
If you are really trying to loop over a feature with different values, again, refer to the above doc, and there are plenty of examples if you look around. Look at all the ones that start with call- here: https://github.com/intuit/karate/tree/master/karate-demo
