How to merge to below arrays into an object in Karate API. I tried below code it is not working.
keys = ['foo', 'bar', 'qux']
values = ['1', '2', '3']
Feature: ArrayToObject
Scenario: ArrayToObject Coversion JS script
* def keys = ['foo', 'bar', 'qux']
* def values = ['1', '2', '3']
* def Arr2object =
"""
function (keys, vals) {
return keys.reduce(
function(prev, val, i) {
prev[val] = vals[i];
return prev;
}, {}
);
}
"""
* string text = Arr2object(keys, values)
* print text
Expected something like this
{
"foo": "1",
"bar": "2",
"qux": "3"
}
This might work,
* def Arr2object =
"""
function(keys,values){
var newObj = {};
if(keys.length == values.length){
for (var i = 0; i <= keys.length - 1; i++) {
newObj [keys[i]] = values[i];
}
return newObj;
}
return newObj;
}

Looking at the documentation it is straighforward how to use the ## operator on fields e.g
* def data = { a: 'hello', b: null, c: null }
* def json = { foo: '#(data.a)', bar: '#(data.b)', baz: '##(data.c)' }
* match json == { foo: 'hello', bar: null }
but what if I want to use it on a json object when there are no properties ? E.g. if I am doing something like
* def data = { a: 'hello', b: null, c: null }
* def json = { foo: '#(data.a)', bar: '#(data.b)', jsonObject: {baz: '##(data.c)'} }
* match json == { foo: 'hello', bar: null }
it is complaining that there is an empty object
actual: {foo=hello, bar=null, jsonObject={}}, expected: {foo=hello, bar=null}
and putting ##{baz: '##(data.c)'} or ##({baz: '##(data.c)'}) as jsonObject value does not work as ## is not recognized correctly.
What is the correct syntax?Or is there another way to do what I am describing?
This is actually a somewhat complex conditional substitution. Here's how you can do it:
* def data = { a: 'hello', b: null, c: null }
* def temp = data.c ? { baz: data.c } : null
* def json = { foo: '#(data.a)', bar: '#(data.b)', jsonObject: '##(temp)' }
* match json == { foo: 'hello', bar: null }
Maybe you are over-complicating things, and all you need is this:
* def data = { a: 'hello', b: null, c: null }
* def json = { foo: '#(data.a)', bar: '#(data.b)' }
* if (data.c) json.jsonObject = ({ baz: data.c })
* match json == { foo: 'hello', bar: null }
I have the below json:
{
"id": [
"1A",
"2B"
],
"name": [
"rs",
"mk"
]
}
I want to extract the id value when name is 'rs' or 'mk'. There will be no duplication of name values and the size of id and name keys will always match.
So i have created the following scenario where:
- I iterate through the name array using forEach.
- Find if the value of name matches rs or mk and if it does, retrieve the index.
- Then use this index to find the retrieve the value from id key.
When I run this, the name_rs_idx and name_mk_idx are not being set and are blank.
Scenario: Using forEach and karate.set
* def vals = { id: ['1A', '2B'], name: ['rs', 'mk'] }
* def name_rs_idx = ''
* def rsFun =
"""
function(x, i) {
if(x == 'rs') {
karate.set(name_rs_idx, i);
}
}
"""
* karate.forEach(vals.name, rsFun)
* print 'RS Index - ' + name_rs_idx
* def name_rs_id = vals.id[name_rs_idx]
* print 'RS id -' + name_rs_id
* def name_mk_idx = ''
* def mkFun =
"""
function(x, i) {
if(x == 'mk') {
karate.set(name_mk_idx, i);
}
}
"""
* karate.forEach(vals.name, mkFun)
* print 'MK Index - ' + name_mk_idx
* def name_mk_id = vals.id[name_mk_idx]
* print 'MK id -' + name_mk_id
Maybe i am not using the forEach function correctly or logic is incorrect.
I think you are over-complicating things :) Here is my solution, take time to read and understand it, it will improve your Karate fundamentals ! To simplify things, we first combine the data into an array of { name: '', id: '' } pairs. Then things become much easier.
* def vals = { id: ['1A', '2B'], name: ['rs', 'mk'] }
* def fun = function(x, i){ return { name: vals.name[i], id: vals.id[i] } }
* def pairs = karate.map(vals.name, fun)
* def fun = function(x){ return x.name == 'rs' || x.name == 'mk' }
* def filtered = karate.filter(pairs, fun)
my code for finding index as below
* def list = nestActual #this is API response value which is given at the end
* def searchFor = { category_name: 'books3'}
* def foundAt = []
* def fun = function(x, i){ if (karate.match(x, searchFor).pass) foundAt.add(i) }
* eval karate.forEach(list, fun)
* print "==========foundAt=======" +foundAt
i have tried the above code for finding index where im getting foundAt index as null.
Below is my response where i want to find index of "category_name":"books3"
[
{
"category_id":1, "parent_cat_id":0, "category_name":"books", "slug_name":"books_1", "popular":true,
}, {
"category_id":2, "parent_cat_id":1, "category_name":"books2", "slug_name":"books_2", "popular":false,
}, {
"category_id":3, "parent_cat_id":1, "category_name":"books3", "slug_name":"books3_2", "popular":false,
}, {
"category_id":4, "parent_cat_id":3, "category_name":"mp3", "slug_name":"mp_3", "popular":false, }, {
"category_id":5, "parent_cat_id":3, "category_name":"mp4", "slug_name":"humoristiska_deckare_mysi_deck_3", "popular":false, }, {
"category_id":6, "parent_cat_id":3, "category_name":"video", "slug_name":"video3", "popular":false,
} ]
Please let me know how to find index of "category_name":"books3" using karate
Guess what, there is a far simpler way, the trick is to convert your search target into an array of primitives. Then you can use the List.indexOf() Java method:
Scenario: using the java indexOf api (will change with graal)
* def response = [{ name: 'a' }, { name: 'b' }, { name: 'c' }]
* def names = $[*].name
* def index = names.indexOf('b')
* match index == 1
i have response like { Data: {a: [{ date1: "2018-12-23", date2: "23-11-2018" },{ date1: "2018-12-20",date2: "23-11-2018" }] } }
and want to test if each date1 field is less than today's date and each date2 is less than input date field (i have a date field in input payload) How can i perform that.
In many ways, here is one. Refactoring this code to be cleaner is homework for you :P
* def toTime1 =
"""
function(s) {
var SimpleDateFormat = Java.type('java.text.SimpleDateFormat');
var sdf = new SimpleDateFormat("yyyy-MM-dd");
return sdf.parse(s).time
}
"""
* def toTime2 =
"""
function(s) {
var SimpleDateFormat = Java.type('java.text.SimpleDateFormat');
var sdf = new SimpleDateFormat("dd-MM-yyyy");
return sdf.parse(s).time
}
"""
* def input = toTime2("24-11-2018")
* def today = new java.util.Date().time
* def isValid1 = function(x){ return toTime1(x) < today }
* def isValid2 = function(x){ return toTime2(x) < input }
* def response = [{ date1: "2018-12-23", date2: "23-11-2018" }, { date1: "2018-12-20", date2: "23-11-2018" }]
* match each response == { date1: '#? isValid1(_)', date2: '#? isValid2(_)' }
I want to display "population" of various countries through the years in the same line chart. The data displayed is based on selections from a multi-select dropdown "Countries". Underlying Data Table has 3 columns:
Year, Country, Population
2012,countryA,33
2013,countryA,35
2014,countryA,40
2012,countryB,65
2013,countryB,70
2014,countryB,75
2012,countryC,15
2013,countryC,20
2014,countryC,25
I am trying to create a pivoted Data View from the underlying Data Table
The code I am using is:
function drawLineChart() {
var arr = $('#country').val();
var lineChartJson = $.ajax({
url: "../json/lineChart.json",
dataType: "json",
async: false
}).responseText;
var lineChartData = new google.visualization.DataTable(lineChartJson);
var view = new google.visualization.DataView(lineChartData);
var viewCols = [0];
for(var i = 0; i < arr.length; i++) {
var viewCols1 = [{
type: 'number',
label: arr[i],
calc: function (dt, row) {
return (dt.getValue(row, 1) == arr[i]) ? dt.getValue(row, 2) : null;
}
}];
viewCols = viewCols.concat(viewCols1);
}
view.setColumns(viewCols);
var aggCols = [{
column: 1,
type: 'number',
label: view.getColumnLabel(1),
aggregation: google.visualization.data.sum
}];
for(var i = 2; i < 4; i++) {
var aggCols1 = [{
column: i,
type: 'number',
label: view.getColumnLabel(i),
aggregation: google.visualization.data.sum
}];
aggCols = aggCols.concat(aggCols1);
}
var pivotedData = google.visualization.data.group(view, [0], aggCols);
But this does not seem to work as expected and I just get 1 Line in the chart with values for all countries added up (although I can see the legend for 3 countries)
On the other hand if I set my View columns as below, it works as expected.
view.setColumns([0, {
type: 'number',
label: arr[0],
calc: function (dt, row) {
return (dt.getValue(row, 1) == arr[0]) ? dt.getValue(row, 2) : null;
}
}, {
type: 'number',
label: arr[1],
calc: function (dt, row) {
// return values of C only for the rows where B = "bar"
return (dt.getValue(row, 1) == arr[1]) ? dt.getValue(row, 2) : null;
}
}, {
type: 'number',
label: arr[2],
calc: function (dt, row) {
return (dt.getValue(row, 1) == arr[2]) ? dt.getValue(row, 2) : null;
}
}]);
What is going wrong in the loop? Is something wrong with "concat" in the loop where I am creating View Columns? I also saw the viewCols array by using console.log and it seems to have the right elements
I was trying to follow the below post:
Creating pivoted DataView from existing google charts DataTable object
the problem has to do with scope
arr[i] is undefined within calc: function (dt, row)
here is another way to pivot the data...
google.charts.load('current', {
callback: function () {
var arr = [
'countryA',
'countryB',
'countryC'
];
var lineChartData = google.visualization.arrayToDataTable([
['Year', 'Country', 'Population'],
[2012,'countryA',33],
[2013,'countryA',35],
[2014,'countryA',40],
[2012,'countryB',65],
[2013,'countryB',70],
[2014,'countryB',75],
[2012,'countryC',15],
[2013,'countryC',20],
[2014,'countryC',25]
]);
// sort by year
lineChartData.sort([{column: 0}]);
// get unique countries
var countryGroup = google.visualization.data.group(
lineChartData,
[1]
);
// build country data table
var countryData = new google.visualization.DataTable({
cols: [
{label: 'Year', type: 'number'},
]
});
// add column for each country
for (var i = 0; i < countryGroup.getNumberOfRows(); i++) {
countryData.addColumn(
{label: countryGroup.getValue(i, 0), type: 'number'}
);
}
// add row for each year / country
var rowYear;
var rowIndex;
for (var i = 0; i < lineChartData.getNumberOfRows(); i++) {
if (rowYear !== lineChartData.getValue(i, 0)) {
rowYear = lineChartData.getValue(i, 0);
rowIndex = countryData.addRow();
countryData.setValue(rowIndex, 0, rowYear);
}
for (var x = 1; x < countryData.getNumberOfColumns(); x++) {
if (countryData.getColumnLabel(x) === lineChartData.getValue(i, 1)) {
countryData.setValue(rowIndex, x, lineChartData.getValue(i, 2));
}
}
}
// draw agg table
new google.visualization.ChartWrapper({
chartType: 'Table',
containerId: 'table-div',
dataTable: countryData
}).draw();
// draw line chart
new google.visualization.ChartWrapper({
chartType: 'LineChart',
containerId: 'chart-div',
dataTable: countryData
}).draw();
},
packages: ['corechart', 'table']
});
<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="table-div"></div>
<div id="chart-div"></div>
I could figure out the problem with my code above.
"calc" is the callback function in loop. So only last value of loop variable "i" is visible within the loop.
Putting a wrapper function fixes it:
for(var i = 0; i <= arr.length; i++)(function(i) {
var viewCols1 = [{
type: 'number',
label: arr[i],
calc: function (dt, row) {
return (dt.getValue(row, 1) == arr[i]) ? dt.getValue(row, 2) : null;
}
}];
viewCols = viewCols.concat(viewCols1);
})(i);
