How does selenium commands browser ?
I know that selenium proxy's requests to urls and on reponse injects selenium core js api into the response. but how does "click" or any other command reach the browser ? In other words how does selenium invoke the selenium core api injected in the browser page ?
Selenium recommends the use of WebDriver to replace the remote control functionality. TMK, the older code injected Javascript into the browser and communicated via that. The WebDriver code uses the native API for each browser.
"Selenium-WebDriver makes direct calls to the browser using each browser’s native support for
automation." via http://seleniumhq.org/docs/03_webdriver.html#selenium-2-0-features
Selenium RC runs a request-loop in the browser (in the Selenium window or frame), and the RC server acts as a forwarding agent between the client and the browser. Here's the sequence:
The test script calls Selenium.Click('SUBMIT').
The client issues an HTTP request that tells the server "next time the browser asks, tell it to click on the 'SUBMIT' button".
The browser may already have an HTTP request waiting for a response, but if not, it will soon.
When the browser sends its HTTP request, the server responds with "click the 'SUBMIT' button".
The browser does what it's told and sends another HTTP request to the server, indicating that the command succeeded.
The server responds to the client's existing HTTP request with an "OK" response.
The Click() routine returns to the script.

I have a simple performance test flow in an application.
Login
Process1
Process2
Process3
Logout
I am using Jmeter/Selenium to do a performance testing. I am currently debugging an endpoint in Process3("/example/path"). The problem is that I have to run the entire automation for me to get to that endpoint in Process3. Is there a way to skip the processes and navigate to that specific endpoint(not headless)? For example:
WDS.sampleResult.sampleStart();
WDS.browser.get("https://domain/path/path/endpoint");
//Authentication
implicitFind(pkg.By.id("username")).sendKeys("user");
implicitFind(pkg.By.id("password")).sendKeys("password");
implicitFind(pkg.By.id("login")).click();
//below code would be for debugging endpoint in UI
When I run WebDriver Sampler, it presents the login page, which I do not mind asking to login. But after I login, webapp does not go to endpoint and throws a NullPointerException. Would I need to add a Cookie Manager? If so, how would I go with doing this using a WebDriver Sampler. If no, is there another way to successfully achieve this? Thanks in advance.
If the application doesn't properly redirect you to the "endpoint" after logging in - it's your application problem only, there is nothing you can do about it on JMeter or Selenium level.
It you want to run Process 3 only and skip Process 1 and Process 2 just temporarily disable them using "Disable" or "Toggle" context menu actions
As you can see the "greyed out" samplers are not executed.
HTTP Cookie Manager relates only to HTTP Request samplers, https://www.selenium.dev/ is a browser automation framework and browsers handle cookies automatically
I am automating an internal application of my client which is having LDAP authentication.
I am using Selenium 3.141.59 with C#, Chrome browser 78.
Issue:
When I have open browser manually and place url then browser displaying sign-in Pop-up to enter the userID and password. (refer screenshot)
Same time when Selenium launch browser instance then navigate to same url, it's not showing any sign-in pop-up.
Due this I was unable to continue next steps in automation.
I have tried send the userID and password along with url as blow but it's also not redirecting.
https://userID:password#url
Can anyone help me, how to resolve this issue.
What you have tried is not supported any more. You now have to include authentication headers in requests. In your case I would recommend to set up a proxy which would add headers to all outcoming messages of your browser
For example you can use Browsermob Proxy that you can configure just in your tests. Some details of how basic authentication works you can find here. It is solution for Java, however you can find which headers to set up and which values to assign (In short: header - Authorization: Basic username:password Realm="" where username:password is credentials pair encoded in Base64).
This also might be useful for you: How do I encode and decode a base64 string?
UPD: This is solution for Python Selenium.
I am running testcafe tests on an authentication page and I can see that testcafe is modifying/removing/adding the headers when sending the requests to the website and this is blocking me to do 2FA on this page
As soon as I got the issue, I tried to do the automation with Selenium just to confirm it is testcafe issue. As selenium doesn't create a proxy to insert the js scripts and automate the website I could do the automation with selenium, but I want to use testcafe as the site is developed in react.
await t.typeText(this.emailInput, config.userEmail)
.click(this.nextButton)
.typeText(this.passwordInput, config.userPassword)
.click(this.nextButton)
.click(this.otpOption)
.typeText(this.otpInput, this.token)
.click(this.signinButton)
}
When clicking on the next button I should have the 2FA form asking for the code, but I got a page saying was not possible to do the authentication (Something wrong happened) and I saw the response code for the BeginAuth endpoint was 222 without any response instead of 200.
The URL is that I am using to authenticate looks like this one:
https://login.microsoftonline.com/client uuid/oauth2/authorize?response_type=code%20id_token&response_mode=form_post&client_id=client uuid&scope=openid&x-client-Ver=4.0.0
Testcafe team found out this is a bug on testcafe-hammerhead, they have fixed and it is going to be included in the next release.

For now I am generating the cookie in the automation and sending it in the header.
Good day to all.
I'm use Selenium WebDriver to automatically test execute. But on development site using HTTP base autentification. I found AutoAuth addon for Firefox. It save login/password and don't need type credentional each time.
But this plugin don't save credentions. I'm reinstall addon and firefox, delete cookie, but nothing. On this machine in other user plugin work successfylly. Maybe, anybody have and resolve this problem?
To author of addon I wrote already.
Way:https://login:passwd#host don't help too...
Do you mean plugin not working on invoking with webdriver? simple way to create profile and call that provide in webdriver.
Here is the way to create firefox profile. Install that add-in and save credentials.
Call above saved profile in webdriver
ProfilesIni allProfiles = new ProfilesIni();
FirefoxProfile profile = allProfiles.getProfile("selenium");
WebDriver driver = FirefoxDriver(profile);
Thank You,

If it's a HTTP Basic Authentication, then you can set the credentials in the URL. Note that it requires to set the "network.http.phishy-userpass-length" preference to enable it.
Here is a working example with Selenium / Firefox / Python:
from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference("network.http.phishy-userpass-length", 255)
driver = webdriver.Firefox(profile)
driver.get("http://admin:admin#the-internet.herokuapp.com/basic_auth")
The approach I've used very successfully is to set up an embedded Browsermob proxy server (in Java code) and register a RequestInterceptor to intercept all incoming requests (that match the host / URL pattern in question).
When you have a request that would otherwise need Basic auth, add an Authorization HTTP header with the credentials required ('Basic ' + the Base64-encoded 'user:pass' string. So for 'foo:bar' you'd set the value Basic Zm9vOmJhcg==)
Start the server, set it as a web proxy for Selenium traffic, and when a request is made that requires authentication, the proxy will add the header, the browser will see it, verify the credentials, and not need to pop up the dialog.
You won't need to deal with the dialog at all.
Other benefits:
It's a pure HTTP solution, it works the same across all browsers and operating systems.
No need for any hard-to-automate add-ons and plugins, any manual intervention.
No need for custom profiles, custom preferences etc.
You control credentials in your test code, and don't store them elsewhere.
I'm using Stream hub as my push server.
when i used Firefox 4.0.1 as my browser, i saw that stream hub is making periodical Ajax request. But in safari i noticed an error in console regarding ws: (web socket), so i came to a conclusion that safari is making request using ws:// url's while Firefox is making plain Ajax calls.
this is my client code
function start() {
hub = new StreamHub();
hub.connect("http://localhost:7878/streamhub/");
hub.subscribe("HelloWorld", topicUpdated);
console.log("brws. subscribed to helloworld");
}
I have two questions.
1)Is my conclusion correct?
2)how do i monitor HTTP request and response in safari (like firebug net panel).
Thanks
