Unable to Pass Two Parameters as Argument to Javascript Function - karate

I am trying to use karate.call to invoke function of a JS file receiving two arguments (String, Array of String). However the array of string would not be passed on to the JS file.
The JS file contains:
function(query, fragments) {
// Here lies some code
// One of them includes fragments.length;
}
And I call the JS function on another JS file in this way:
//var query = 'Some string';
//var fragments = ['fragment1', 'fragment2'];
var clean = karate.call('../helper/helper.js', [query, fragments]);
I am able to pass query which is a string. But I was unable to pass the array of string. The error says:
TypeError: Cannot read property "length" from undefined
It seems the array of string did not get passed to the JS function. Any help will be greatly appreciated. Thanks!

You can read you function first and invoke is just like any other js function
var myFun = karate.read('../helper/helper.js');
var funCall = myFun(query, fragments);
or
var myCall = karate.read('../helper/helper.js')(query, fragments);
this should work.

.call takes parameters as comma separated values , you need to use .apply if you want to pass values as an array.
var clean = karate.call('../helper/helper.js', query, fragments);
will work...

The answers here are missing an important clarification:
I often do single arg functions like:
* def concatParams =
"""
function(s) {
return "urldt=" + todaysDate + "&caseid=" + s.caseid
}
"""
And I will call that like so:
* def params = call concatParams {caseid: '3433344'}
But, when I want to do 2 params, I will define a function like so:
* def concatParams =
"""
function(d,s) {
return "urldt=" + d.date + "&caseid=" + s.caseid
}
"""
And unintuitively, neither of these will work:
* def params = call concatParams {date: '01/01/2020', caseid: '3433344'}
* def params = call concatParams '01/01/2020' '3433344'
To get it to work, instead I call it like this:
* def params = concatParams('01/01/2020', '3433344')
Documentation does not clarify this.

var clean = karate.call('../helper/helper.js', query, fragments);
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/call

call method accepts comma separated params and apply accept array so you need to replace call into apply. your code looks like
function karate(query, fragments) {
// Here lies some code
// One of them includes fragments.length;
}
var clean = karate.apply('../helper/helper.js', [query, fragments]);

Modified variable name in karate framework [duplicate]

This question already has an answer here:
Karate Http request add param conditionally
(1 answer)
Closed 1 year ago.
I want to modified param variable for my request(GET/POST) dynamically. As I have 2 different environment which takes different parameters for same request.
I tried below code, but not able to replace param variable(name).
I can replace param value successfully.
This function generate the dynamic param name for different enviornment
public static String paramDynamicVariable(String env, String param) {
String paramValue;
if (env.equals("test")) {
paramValue = '$' + param;
} else {
paramValue = param;
}
return paramValue;
}
Now when I am using paramValue in my test--
Scenario: xyz
Given path URLOfRequest
* print paramDynamicVariable(karate.env,'nameParam')
And param random.paramDynamicVariable(karate.env,'nameParam') = 10
It prints correct value, but in the next line it is not replacing for param name.
Please suggest if any solution is there to dynamic param name.
Please do something like this:
* def nameParam = paramDynamicVariable(karate.env, 'nameParam')
* def paramValues = {}
* paramValues[nameParam] = 10
And then:
* params paramValues
Since params accepts any JSON, all you need to do is create the JSON. Since the key is dynamic, it requires you to do a little more work.

Groovy : Class.forName().newInstance() error

I have this following method in which I return a List<ImField> object using the List<GPathResult> filteredList. I perform filteredList.each closure where I generate
class at runtime and assign it a static type of ImField.
static List<ImField> getFields(GPathResult root,String fieldClass, String fieldType){
List<GPathResult> filteredList = root.children().findAll{
XMLSlurperUtil.name(it as GPathResult) == fieldType
} as List<GPathResult>
List<ImField> fields = []
filteredList.each{GPathResult it, int index ->
fields.add(Class.forName(fieldClass).newInstance() as ImField)
fields[index].set(it)
}
fields
}
The function call would look like so :
ImStageUtil.getFields(root, ImFieldFactory.SOURCE_FIELD, ImParserConstants.SOURCE_FIELD)
where ImFieldFactory.SOURCE_FIELD = "com.dto.fields.SourceField"
and ImParserContants.SOURCE_FIELD = "SOURCEFIELD"
the error occurs at the .each closure line:
No signature of method: com.extractor.ImStageUtil$_getFields_closure11.doCall() is applicable for argument types: (groovy.util.slurpersupport.NodeChild) values: []
Possible solutions: doCall(groovy.util.slurpersupport.GPathResult, int), findAll(), findAll(), isCase(java.lang.Object), isCase(java.lang.Object)
groovy.lang.MissingMethodException: No signature of method: com.extractor.ImStageUtil$_getFields_closure11.doCall() is applicable for argument types: (groovy.util.slurpersupport.NodeChild) values: []
Possible solutions: doCall(groovy.util.slurpersupport.GPathResult, int), findAll(), findAll(), isCase(java.lang.Object), isCase(java.lang.Object)
I've tried to create a similar script to your example, there are two things I had to modify (if your filteredList is not empty, which you need to check first):
1- You need to use collect() after the findAll{} closure, this allows you to collect all entries and add them to your filteredList.
2- You're using .each{} and you're providing a List along with the index, this should be replaced by .eachWithIndex{} because the first one doesn't expect an index.
Here is a simplified version of your code:
import groovy.util.slurpersupport.GPathResult
def text = '''
<list>
<technology>
<name>Groovy</name>
</technology>
</list>
'''
def list = new XmlSlurper().parseText(text)
def List getFields(GPathResult root,String fieldClass, String fieldType){
List<GPathResult> filteredList = root.children().findAll{
//println(it)
it != null
}.collect() as List<GPathResult>
println('list: ' + filteredList.getClass() + ', ' + filteredList.size())
filteredList.eachWithIndex{GPathResult it, int index ->
println('it: ' + it)
}
}
getFields(list, '', '')
This last example doesn't raise any exception for me.
Hope this helps.

Expression with String placeholder in the filter part of JsonPath using karate

I am trying to filter my response using JSON Path where one of the condition using a value from a variable but I am not able to map variable properly, so my filter not working properly.
Sample response JSON:
{
"response":[
{
"id":"1234",
"confirmationCode":"abcd"
}
]
}
I am using the below script where I am using variable 'code':
* def Code = 'abcd'
* def value = karate.jsonPath($.response[?(#.confirmationCode == ' + Code +')])
Read the docs carefully please:
* def value = karate.jsonPath(response, "$.response[?(#.confirmationCode=='" + Code + "')]")

how can we pass multiple arguments in the background functions in karate feature file

i am passing the two arguments to my custom function but in background while i am passing the arguments it's skipping first taking second one only arugment.
here is the sample code
* def LoadToTigerGraph =
"""
function(args1,args2) {
var CustomFunctions = Java.type('com.optum.graphplatform.util.CareGiverTest');
var cf = new CustomFunctions();
return cf.testSuiteTrigger(args1,args2);
}"""
#*eval if (karate.testType == "component") karate.call(LoadToTigerGraph '/EndTestSample.json')
* def result = call LoadToTigerGraph "functional","/EndTestSample.json"
output :
test type is ************/EndTestSample.json
path is *************undefined
When you want to pass two arguments, you need to send them as two json key/value.
* def result = call LoadToTigerGraph { var1: "functionnal", var2: "/EndTestSample.json" }
And you just have to use args.var1 and args.var2 in your function function(args)

Use of a string to get information in an associative array

I've got a function that takes two strings as arguments, and I want to use these arguments to get the data held in associative arrays.
var myVar:Object = {};
myVar.value = 10;
function getStuff(v:String, vl:String){
//...
}
In this case, v = "myVar" and vl = "value".
How do I translate vinto the variable name 'myVar' and v1 into 'value' so that I can access the data?
Sorry if this won't work, for I can only test AS3 here, but please try this:
function getStuff(v:String, vl:String){
return eval(v + "." + vl);
}
eventually
function getStuff(v:String, vl:String){
return eval("_gobal." + v + "." + vl);
}
