by using phantomjs and or casperjs, is it posible to execute a javascript function that defined on the remote site ?
all i see in the docs is only to call builtin function in phantomjs and casperjs
is there anyway to do this with phantomjs and or casperjs ?
Use its code evaluation feature (see the documentation for more details), e.g:
page.evaluate(function () {
// do whatever you want, including calling any function
});
2 years later I stumbled upon the same problem. Here is the solution you were looking for.
page.evaluateJavaScript(function(){
javascriptFunction();
});

I tried my best but could not find information on calling an API inside the Javascript function when dealing with automation in Karate. Now, I might get suggestions to call the API outside the function and then do operations inside the function. However, my use case is such that I have to call the API inside the function only. Is there a way to do this?
One approach is to create a Java file and then write the code in java. However, I specifically want to know if there is any way to call an API inside a JS function in a FEATURE FILE itself.
First, these kinds of "clever" tests are not recommended, please read this to understand why: https://stackoverflow.com/a/54126724/143475
If you still want to do this, read on.
First - most of the time, this kind of need can be achieved by doing a call to a second feature file:
* if (condition) karate.call('first.feature')
Finally, this is an experimental and un-documented feature in Karate, but there is a JS API to perform HTTP requests:
* eval
"""
var http = karate.http('https://httpbin.org');
http.path('anything');
var response = http.get().body;
karate.log('response:', response);
"""
It is a "fluent API" so you can do everything in one-line:
var body = karate.http('https://httpbin.org/get').get().body;
If you need details, read the source-code of the HttpRequestBuilder and Response classes in the Karate project.
The process for writing multiple windows tests described in TestCafe documentation seems pretty straightforward:
await t.openWindow('https://url.com/addnewproperty')
or even
const initialWindow = await t.getCurrentWindow()
should do it. However, every time I use any of the Window Management methods I get the errors:
TypeError: t.openWindow is not a function and cannot do anything about it.
Does anyone know what am I doing wrong and how to solve the issue?
TestCafe version 1.9.4
The problem was in different versions of Test Cafe used between main codebase and one of the underlying packages. Alex Kamaev answer was a correct one
According to this article, Selenium 4 alpha has a sendDevToolsCommand that sends an arbitrary DevTools command to the browser and returns a promise that will be resolved when the command has finished:
Added “sendDevToolsCommand” and “setDownloadPath” for chrome.Driver.
But I can't seem to find how to use it. It sounds a bit like using JavaScript executor in Selenium.
Can someone provide an example usage? I'm using Selenium + Java.
The command to call the devtool api was added a few years back in the Chrome driver.
You can already use it with Selenium even if the method is not yet present:
Take full page screenshot
Print To PDF
Inject some Javascript before the page loads
Block a network URL
Save/restore the cookies for all domains
Get transparent screenshot
This command gives you access to the devtools api, which is used by ChromeDriver internally to drive the browser.
The method takes the name of the command as first argument and a dictionary of parameters as second argument. To figure out how to call a command, add puppeteer in your searches. For instance puppeteer set download location.
Note that executeCdpCommand is implemented in the Java master branch, so it should be available in the next release.
I couldn't find the sendDevToolsCommand in the Selenium documentation yet, but the source actually has the setDownloadPath that you also mentioned above defined right below, which actually uses the sendDevToolsCommand. Based on that usage, it seems like you could do something like:
const { Builder } = require("selenium-webdriver");
const driverInstance = await new Builder()
.withCapabilities({ browserName: "chrome" })
.build();
driverInstance.sendDevToolsCommand('Page.setDownloadBehavior', {
behavior: 'allow',
downloadPath: path
})
or for a visually obvious example:
await driverInstance.sendDevToolsCommand("Emulation.setDefaultBackgroundColorOverride", {
color: { r: 0, g: 255, b: 0, a: 1 } // watch out, it's bright!
});
where the first argument is a Chrome Devtools Protocol Domain method (e.g. or Page.setDownloadBehavior or Emulation.setCPUThrottlingRate) and the second argument is an object containing the options for that Domain method (as described in the same protocol docs).
Edit: just tested and the above works :)
I'm excited that this was added because it means that, in addition to network throttling, it should be pretty trivial to add cpu throttling to Selenium tests now! Something like:
driverInstance.sendDevToolsCommand('Emulation.setCPUThrottlingRate', {
rate: 4 // throttle cpu 4x
}
Selenium 4 release will have a user friendly API for Chrome DevTools protocol.
I just finished implementing Network and Performance domains for the Selenium Java client.
https://github.com/SeleniumHQ/selenium/pull/7212
In addition, there is a generic API for all domains in Java client that was merged a while ago.
All those new features will be released probably in the next Alpha release.
I have installed xwiki successfully and able to generate wiki pages using velocity template language.
Could anyone please tell me that how can I pass javascript varible to velocity templete. I have gone through few forums that I need to pass the parameter to server to get this but I have no idea. Please find the files below.
<script type="text/javascript">
function generateFunction()
{
var variable = document.getElementById('text').value;
}
</script>
#set($test = "variable")
$test
You have to make an ajax call from the client to the server.If you're using jquery, you would have something like:
$.post('/send/my/var', { 'variable' : value });
Without jquery, see this XmlHttpRequest documentation.
And then, on the server side, the /send/my/var URL should reach a template where you can do:
#set($test = $params.variable)
And you would do something useful with it on the server-side, like store it in the session, in the database, etc.
If you need to send back something from Velocity to Javascript, then you'll typically have to format JSON code, and add an asynchronous completion callback parameter to the ajax call:
$.post('/send/my/var', { 'variable' : value },
function(data)
{
// do something with data sent back from the server
});
It's also possible to have synchronous calls, that is to have javascript wait for the server response, but it's generally a bad idea to do so and I won't extrapolate on it here.
As a final note, you should also implement a proper error handling. With jQuery for instance, the syntax would be:
$(document).ajaxError(function(event, jqxhr, settings, message)
{
console.log(message);
});
It can't be done,
Apache Velocity template is a server side engine,
Meaning that on the server, Velocity will get the template and try to render, only after it finished to render the template, it will be returned to client which will execute client code as Javascript
Velocity alternative is freemarker, which I found similar question and answer , Question:
How to call freemarker function with param from javascript
Answer:
There's no way for the client side web browser code to call a server side Freemarker function
I'm attempting to mock the response of a dojo xhr request, but I haven't found a good solution.
Ideally, I'd like to see a solution similar to the jQuery mockjax plugin where I can set a specific call based on a url, e.g.:
$.mockjax({
url: '/restful/fortune',
responseTime: 750,
responseText: {
status: 'success',
fortune: 'Are you a turtle?'
}
});
My initial thought was to utilize the "/dojo/io/send" channel, but I haven't been able to get a modified response to be loaded after modifying the dojo Deferred object.
The other thought is to use a pass-through method that would determine if an actual xhr request should be made, e.g.:
function xhrRequest(xhrArgs) {
if(shouldMock) {
var fakeReturnJson = dojo.toJson({
howdy: "that's odd!",
isStrange: false
});
return fakeReturnJson;
} else {
dojo.xhr(xhrArgs);
}
}
Can someone tell me the best way to go about mocking dojo xhr calls?
Thanks!
It's an old question, but I think you should do your mocking using Sinon.js
However you will need to put the following:
has: { native-xhr2: false }
into your dojoConfig for it to work in 1.8
I haven't heard of any Dojo specific libraries similar to Mockjax. But what I think you could try is use Mockjax with Dojo. This should be pretty easy to do since all you'll have to do is use JQuery during development only for testing with Mockjax and then remove it once development is complete.
I use your second suggestion. Currently, I have a transport layer (simple js class) and 2 implementations (XhrTransport and MockTransport). I then switch in which I need without changing the widget code.
Widgets call the server with:
Controller.send(aServerCall);
where aServerCall is a simple value object with the server endpoint, params and callback.
This way, you can add nice things to the controller that will apply to all server calls (such as logging, analytics, generic error handling...) and also mock out the entire server when doing unit tests.
For the MockTransport, I simply return canned json data from static .js files in the format that the widget expects.
