I want to be able to automate my tests using Microsoft Edge browser using Selenium GoDog framework. Can someone please provide suggestions on how to invoke edge browser using new Selenium service method and how to set up the capabilities and service option?
Cannot find service method for edge we have chrome only

What is Selenium?
When you open the official page of the Selenium, the first thing you read is "Selenium automates browser" in "What is Selenium?" section.
The section "Which part of Selenium is appropriate for me?" below offers the choice between Selenium WebDriver and Selenium IDE.
From this, I deduce that Selenium is a collection of tools and the collection comprises IDE, WebDriver API(language binding), Grid, Selenium Standalone Server, browser driver. One has to download the appropriate ones to build a project.
What is WebDriver?
WebDriver is an API. It is written in more than one language which and they are called language bindings. The API has functions to control a browser. You use the functions in writing a script that controls a browser in the way(test case) you want.
This is what I know. Please correct me wherever I'm wrong. I want to know the answers to the two questions in the interview point of view.
Selenium
Selenium is a free (open source) automated testing suite for web applications across different browsers and platforms. Primarily it is used for automating web applications for testing purposes, but is certainly not limited to just that. Selenium has the support of all of the major browser vendors who have taken (or are taking) steps to make Selenium a native part of their browser. It is also the core technology in countless other browser automation tools, APIs and frameworks.
Selenium is not just a single tool but a set of different software tools each with a different approach to support the test automation of an organization. From a broader perspective previously it had four components as follows:
Selenium Integrated Development Environment (IDE)
Selenium Remote Control (RC)
WebDriver
Selenium Grid
An year ago, Selenium RC and WebDriver are merged into a single framework to form Selenium 2.x. Perhaps, Selenium 1 refers to Selenium RC. The current released version is Selenium 3.x.
WebDriver
Selenium-RC worked the same way for each supported browser. It injected javascript functions into the browser when the browser was loaded and then used its javascript to drive the AUT within the browser. Selenium WebDriver fits in the same role as Selenium-RC did and has incorporated the original 1.x bindings and included the WebDriver API. It refers to both the language bindings and the implementations of the individual browser controlling code. This is commonly referred to as just WebDriver. In short, WebDriver is the remote control interface that enables introspection and control of user agents. WebDriver provides a platform and language-neutral wire protocol as a way for out-of-process programs to remotely instruct the behavior of web browsers.
Highlights of WebDriver
WebDriver is designed in a simpler and more concise programming interface along with addressing some limitations in the Selenium-RC API.
WebDriver is a compact Object Oriented API when compared to Selenium1.0
It drives the browser much more effectively and overcomes the limitations of Selenium 1.x which affected our functional test coverage, like the file upload or download, pop-ups and dialogs barrier
WebDriver overcomes the limitation of Selenium RC's Single Host origin policy.
Current Implementation
WebDriver is the name of the key interface against which tests should be written in Java/C#/Ruby/Python/NodeJS, the implementing classes which you can use are listed as below:
ChromeDriver
EventFiringWebDriver
FirefoxDriver
HtmlUnitDriver
InternetExplorerDriver
PhantomJSDriver
RemoteWebDriver
SafariDriver
What is Selenium
It is a suite of tools that can be used to automate web browsers testing.
Each tool serves different purpose.
List of tools:
Selenium IDE
Selenium RC
WebDriver
Selenium Grid
Selenium RC was merged with WebDriver since Selenium 2
What is WebDriver
Selenium WebDriver is an interface that permits us to execute tests over browsers.
Selenium WebDriver allows us to choose a programming language of your choice to create test scripts.
Please find the image below explaining how exactly WebDriver communicates with the browser :
What is Selenium?
Selenium is a framework where scripts are written to run and execute webDriver which in turn controls browser.
What is WebDriver?
WebDriver is an API, the name itself suggests driving the web browser or controlling the web browser by using libraries and commands.
The one and only job of WebDriver is to control the browser, it doesn't know anything about testing and how to interact with browser, At this point FrameWork comes into picture where Scripts are written to run and execute WebDriver.
What is Selenium?
You can say it is a web application automation framework.
What is WebDriver?
This is certainly an API but to understand easily you can think it as a library collection.
I think it's also worth noting that the WebDriver controls the browser, and that Selenium is the piece that sends/receives method calls and data from/to the driver using the "wire protocol" that the WebDriver creates. So the WebDriver is the bridge from the browser to any other code that wants to communicate with it. Selenium also provides an interface (in the coding sense...) that is standard across different WebDrivers. So when you declare a WebDriver type it is implementing the interface. (This is my current understanding anyway and I'm always learning something new!)
Is there a way to record / generate a video file of the browser session for selenium webdriver with the following setup?
Environment / Test Setup:
e2e web tests (written in any language)
selenium standalone server with chrome
Since, there is no direct support from selenium, you may use third party tool like Monte Media Library. See the link:
How to perform screen recording with the help of selenium?
Hope, this will help you.
There are many selenium webdriver binding package of Golang.
However, I don't want to control browser throught server.
How can I control browser with Golang and selenium without selenium server?
You can try github.com/fedesog/webdriver which says in its documentation:
This is a pure go library and doesn't require a running Selenium driver.
I would characterize the Selenium webdriver as a client rather than a server. Caveat: I have used the Selenium webdriver (Chrome version) from .Net and I am assuming it is similar for Go.
The way Selenium works is that you will launch an instance of it from within code, and it creates a live version of the selected browser (i.e. Chrome) and your program retains control over it. Then you write code to tell the browser to navigate to a page, inspect the response, and interact with the browser by filling out form data, clicking on buttons, etc. You can see what is happening on the browser as the code runs, so it is easy to troubleshoot when the interaction doesn't go as planned.
I have used Selenium to upload tens of thousands of records to a website that has no API and only a graphical user interface. Give it a chance.
I am using htmlunit for web scraping - logging to a website on behalf of the users, settings something in their profile and then come back.
Just using pure Htmlunit and no selenium framework.
Now my question:
WebClient webClient = new WebClient(BrowserVersion.INTERNET_EXPLORER_11);
Does this statement - creates a browser instance on the machine where i am executing the code or what it does?
I am using BrowserVersion.INTERNET_EXPLORER_11 as this is an accepted browser at that website.
How Selenium is different than htmlunit - i know we can use htmlunit as a webdriver in Selenium. Does Selenium needs a native browser instance on the machine where the code is getting executed? Does Selenium creates browser instances?
My use case is - I will be having multiple users accessing this application. I know WebClient in htmlunit is not thread safe(so have to code it as Spring proto type bean).
Is there any suggestions regarding this?
Any help is greatly appreciated.
HTMLUnit is a headless browser. So no window will be created if used with Selenium either. Setting the BrowserVersion will just tell HTMLUnit to present itself to the server as if it were a given browser (AFAIK, it will just change the User-Agent but might perform additional internal processing depending on the version). I guess this answers most of the questions but the last one.
Regarding asking for suggestions on how to implement this I would try to avoid logging in to a website that way. If the website does not provide an API for this then it is likely that it is agains the Terms Of Service. Assuming it is not, you will have to create new WebClient instances for each user each time the data needs to be extracted from the other site.
I have successfully tested applications in FireFox using Selenium WebDriver, but one of our applications runs in a custom browser made using QTWebKit. Is it possible to use WebDriver to automate testing in a custom browser like this?
There is a webdriver for QtWebkit here: https://github.com/cisco-open-source/qtwebdriver
It also can automate qtwidget and QML aplications.
You should be able to use it to automate you custom browser, provided you preserved the QtWebkit APIs.
If QTWebKit has released a WebDriver executable for the browser, then yes.
Otherwise - no.
