I am trying to call an API in second feature file , passing arguments from first feature file . Say token and current page value which is returned from a first API response.These has to be passed as a param for second API
* def activeDetails =
"""
function(times){
for(i=0;i<=times;i++){
karate.log('Run test round: '+(i+1));
karate.call('getActiveRouteDetails.feature', { token: token, currentPage: i });
}
java.lang.Thread.sleep(1*1000);
}
"""
* call activeDetails totalPages
In my second feature , I am able to print the values passed , but unable to pass in params . Can you please help me
And print currentPage
And print token
And param pageNumber = '#currentPage'
And param token = token
There is a subtle difference when you are in a JavaScript block. Please read this: https://github.com/intuit/karate#karate-expressions
Make this change:
var result = karate.call('examples/getDetails.feature', { token: token, currentPage, i });
And please don't have variable names like current page, take the help of a JavaScript programmer friend if needed for help.
Also note that the best practice is to avoid JS code and loops as far as possible: https://github.com/intuit/karate#loops

I have written the code:
function getId(username) {
var infoUrl = "https://www.instagram.com/web/search/topsearch/?context=user&count=0&query=" + username
return parseInt(fetch(infoUrl)['users']);
}
function fetch(url) {
var ignoreError = {
"muteHttpExceptions": true
};
var source = UrlFetchApp.fetch(url, ignoreError).getContentText();
var data = console.log(source);
return data;
}
To get the userID of the username input.
The error corresponds to the line:
return parseInt(fetch(infoUrl)['users']);
I have tried differnt things but I cant get it to work. The url leads to a page looking like this:
{"users": [{"position": 0, "user": {"pk": "44173477683", "username": "mykindofrock", "full_n........
Where the numbers 44173477683 after the "pk": are what I am trying to get as an output.
I hope someone can help as I am very out of my depth, but I guess this is how we learn! :)
I was surprised that the endpoint you provided actually led to a JSON file. I would have thought that to access the Instagram API, you would need register a developer account with Facebook etc. Nevertheless, it does return a JSON by visiting in the browser. I suppose that it just shows the publicly available information on each user.
However, with Apps Script it seems like a different story. I visited:
https://www.instagram.com/web/search/topsearch/?context=user&count=0&query=user
In a browser and chose a random user id. Then I called it from Apps Script with UrlFetchApp:
function test(){
var username = "username7890543216"
var infoUrl = "https://www.instagram.com/web/search/topsearch/?context=user&count=0&query=" + username
var options = {
'muteHttpExceptions': true
}
var result = UrlFetchApp.fetch(infoUrl, options)
console.log(result.getResponseCode())
}
Which returns a 429 response. Which is a "Too Many Requests" response. So if I had to guess, I would say that all requests to this unauthenticated endpoint from Apps Script have been blocked. This is why when replacing the console.log(result.getResponseCode()) with console.log(result.getContentText()), you get a load of HTML (not JSON) part of it which says:
<title>
Page Not Found • Instagram
</title>
Though maybe its IP based. Try and run this code from your end, unless you get a response code of 200, it is likely that you simply can't access this information from Apps Script.
You are setting data to the return value of console.log(source) which is undefined. So no matter what the data is, you will get undefined.
Another thing to avoid is that fetch will not necessarily be hoisted because fetch is a built in function to make API calls.
Ok, so I am going to explain what my scenario is and how I have implemented it using karate. But i am looking for a better way of doing things which make my tests more readable and also want to use karate's api rather than too much javascript.
Scenario: I have a filter parameter for the api endpoint that i am testing and this filter param takes a json object of key-value pairs. So i have done the following:
Have created a filter-template.js as below:
function() {
var filter_params = {
jobId:null,
customerIds:[],
filterValues1:[],
filterValues2:[],
};
return filter_params;
}
I read this template in my karate scenario and because this is a template, at runtime i set the values in this template and run the test. I will have different values for key-value pairs so each test will set its own filter condition.
This is done by writing custom js function that takes the template as argument and also the filter condition values (referring to arg function argument below), sets the passed conditions to specific key's and then returns json object. Code below:
Scenario: Set filter scenario
* def filter_template = call read('filter-template.js')
* def filter_vals_list = [1001,1002]
* def filter_condition = { cnd1: 'foo', cnd2: '#(filter_vals_list)' }
* def setFilter =
"""
function(arg) {
var i;
var filter = arg.template;
filter.jobId = arg.condition.cnd1;
for(i=0;i<arg.condition.cnd2.length;i++)
{
filter.filterValues1.add(arg.condition.cnd2.get(i));
}
return filter;
}
"""
* def getFilter = call setFilter { template: '#(filter_template)',
condition: '#(filter_condition)' }
I then pass the getFilter as a param to my api request.
What I am hoping to understand is:
How can i get away from using JS loops above when setting filter?
Use karate's in-built functions like karate.map(), karate.forEach() to simplify the tests.
Any better approach if possible on tackling this scenario.
Help and guidance much appreciated.
From what I understood, I have simplified your scenario below:
* def filter_vals_list = [ 1001, 1002 ]
* def job_id = 'foo'
* def filter_template =
"""
{
jobId: '#(job_id)',
customerIds: [],
filterValues1: '#(filter_vals_list)',
filterValues2: [],
}
"""
Let me know if I missed anything. Please refer embedded expressions: https://github.com/intuit/karate#embedded-expressions
Now, you can easily use a re-usable JSON for the template, by changing the last step to the below, and yes - embedded expressions work even in re-usable JSON files !
* def filter_template = read('filter-template.json')
You may get even better ideas once you try the data-driven Scenario Outline. So hope that makes it clear how you are un-necessarily complicating things with JS ! You don't even need karate.map() etc.
I have a variable called token with a specific value myTokenValue
I try to make a call that includes that variable in a header, tokenHeader:{{token}}
I also have a pre-request-script that needs to change the request based on the value of the token header, but if I try to read the value pm.request.headers.get('tokenHeader') I get the literal value {{token}} instead of the interpolated myTokenValue
How do I get this value without having to look at the variable directly?
You can use the following function to replace any Postman variables in a string with their resolved values:
var resolveVariables = s => s.replace(/\{\{([^}]+)\}\}/g,
(match, capture) => pm.variables.get(capture));
In your example:
var token = resolveVariables(pm.request.headers.get('tokenHeader'));
Basically I was missing a function to interpolate a string, injecting variables from the environment
There are some workarounds:
write your own function, as in this comment by pomeh
function interpolate (value) {
return value.replace(/{{([^}]+)}}/g, function (match, $1) {
return pm.variables.get($1);
});
}
use Postman's own replaceSubstitutions, as in this comment by codenirvana
function interpolate (value) {
const {Property} = require('postman-collection');
let resolved = Property.replaceSubstitutions(value, pm.variables.toObject());
}
Either of these can be used as
const tokenHeader = interpolate(pm.request.headers.get('tokenHeader'));
but the second one is also null safe.
I am having an issue with AWS Cognito provided UI.
When I am trying to use the provided UI, I call the endpoint with populated URL:
https://mydomain.auth.ap-northeast-1.amazoncognito.com/login?response_type=token&client_id=123456789&redirect_uri=http://localhost:3000/callback/
Now the problem is that, after authentication, Cognito uses a # to send back the required parameters. The result would look like this:
http://localhost:3000/callback/#id_token=eyJragIsm2PqVpw&access_token=eyJraWQiOiJ&expires_in=3600&token_type=Bearer
I have a hard time reading id_token and access_token in my callback page (which is a vue app).
How can I configure Cognito to use the usual question mark (?) to pass query string, Or, How can I read the passed parameters after hash (#).
I appreciate your advise on this.
If you are using Vue.js router, it is actually pretty easy to process the hash part. Just put this snippet somewhere in your component.
reference: https://router.vuejs.org/api/#the-route-object
let cognitoData = {}
if (this.$route.hash !== "") {
let elementsString = decodeURIComponent(
this.$route.hash.substr(1, this.$route.hash.length)
);
let params = elementsString.split("&");
for (let param of params) {
let values = param.split("=");
cognitoData[values[0]] = values[1];
}
}
// do your business with cognitoData
We are facing an issue while trying to pass argument stored in var .
The issue is we are storing the dynmically retrived div id in a variable and then passing it to .moveToObject function.
But the function throws back error ;
Error: invalid selector: No selector specified
Wanted to know how we can pass arguments stored in variables into various functions.
For instance in the code below , we are retiring sectionId via execute , storing it in sectionId variable .
then using it later on in moveToObject.
all functions seems to work when we are giving arguments inside "" quotes, but in our case we cannot do this. Please help us out how we can achieve this.
it('drag and drop should work', function() {
var sectionId = "";
// load page, then call function()
return driver
.url('http://localhost:9000')
.pause(7000)
.click('#layoutWizardButton')
.click('#tableWizardBuild')
.pause(3000)
.execute(function() {
sectionId = window.document.getElementById('Section1');
}
.moveToObject('#ribbon-radio-tile')
.buttonDown()
.moveToObject(sectionId) -- -- > errors out here
.buttonUp()
.pause(2000)
.end()
});
Try .moveToObject(sectionId.value)
