javascript - faking xmlhttprequests with casperjs -


i'm writing end-to-end tests casperjs , fake ajax server responses

i've came idea of including simple script mocks xmlhttprequest object , return expected results, following

var ajax_requests = [ ['get', '/jobs', json.stringify(jobs)] ], stubs = stubs || {}; function setup_ajax(){ stubs.server = sinon.fakeserver.create(); _.each(ajax_requests, function(r){ //r[1] = "http://localhost:8000" + r[1] r[2] = [200, { "content-type": "application/json" }, r[2]] stubs.server.respondwith.apply(stubs.server, r) }) stubs.server.autorespond = true; stubs.server.autorespondafter = 2; }

then call setup_ajax in casper test like

casper.then(function(){ this.evaluate(setup_ajax) }

but seemingly future ajax requests still avoid xmlhttprequest implementation.

i've tried running setup_ajax on fly, using $.ready() , having called casper too, neither of these worked

more interestingly, checking objects' existence strangely fails.

function setup_ajax(){ return typeof(sinon) } casper.then(function(){ var x = this.evaluate(setup_ajax) casper.log(x) // logs 'null' }

but sinon included, @ least casper did not cause errors when i've made calls outside setup_ajax function, caused error when deliberately had sinon excluded.

do have ideas on mocking xmlhttprequests under casperjs?

you can use sinon.js fake xmlhttprequest.

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
