As perhaps the most generally used test automation system on the planet, Selenium is unquestionably a mainstream test framework suite for automating internet browser testing. Today we are opening another blog series orbiting around the subject of the Selenium framework and browser testing.
What is Selenium Framework?
All in all, what really is the Selenium framework? Basically, Selenium is a well-known automation testing suite that can be used to automate desktop and mobile internet browser communications. You can perform automation testing by composing code in any of your preferred language upheld by Selenium and can without much of a stretch run your automation contents to automate testing of an application or a cycle.
There is something else entirely to this that gets similar. Selenium isn’t just a single framework but instead a bunch of systems packaged into a suite. A tool to make the existence of a software analyzer that a lot simpler. It is a fundamental part while making hearty, regression automation suites and tests.
At the point when people consider Selenium, they presumably think about the Selenium WebDriver, which is reasonable as it is the most used tool in the suite. Yet, to completely use Selenium and pick the right tool for the work, it is acceptable to understand which parts make up the mainstream testing system.
Beneath we will go through the tools in more detail, however, the accentuation will lie for the most part on the Selenium WebDriver or Selenium 3, maybe, as it is the key interface when driving a program.
The Selenium Integrated Development Environment is just accessible for two programs, Chrome and Firefox. This expansion makes it simple to record and playback tests in the program. The recorded script can likewise be seen and changed into different languages. Yet, to compose further developed and powerful experiments Selenium RC or WebDriver is suggested.
Selenium RC (Remote Control)
Selenium RC is a client/server framework that permits you to control internet browsers locally or on different PCs, using practically any programming language and testing framework. There are many tools and plugins out there and they can get confusing so that Selenium RC can be interpreted as Selenium 1, at that point RC combined with WebDriver making Selenium 2.0, and afterward, Selenium 3 is an enhancement for Selenium 2. Thusly, the replacement to Selenium RC is the Selenium WebDriver.
With Selenium Grid, you can run equal test meetings by running numerous servers simultaneously with a Hub and Node Architecture. One could view it as a scaled-up Selenium Remote Control. Selenium Grid likewise upholds RC and WebDriver contents. These scripts will be imparted by means of the Hubs out to the Nodes and afterward executed.
Selenium WebDriver is a browser explicit driver which helps in getting to and launching the various browsers whether it’s PC browsers or portable browsers. That implies it doesn’t uphold for instance Windows applications. It gives an interface to compose and run automation content. Each program has various drivers to run tests.
Chrome has ChromeDriver, Safari has SafariDriver, etc, because of the way that each browser has an alternate method of performing activities for example loading a page.
WebDriver has the capacity to test current and dynamic sites, destinations where content is changing progressively with a tick of a catch for instance. As you will discover later when we go through the engineering, it works by communicating with the browser in pretty much a similar manner as a real client would.
The Selenium WebDriver architecture works in an accompanying manner. You compose your tests in your preferred programming language, this is imparted in JSON over HTTP (REST API) to the program explicit driver which at that point, thusly, start-up and communicates by means of HTTP to the actual browser, and the browser conveys back with an HTTP reaction.
Accordingly, it doesn’t make any difference what language you use as Selenium speaks with the Client Library and the Browser Driver will at that point handle the particular activities.
Why Use Selenium Framework for Automated Browser Testing?
As we presently know about the makeup of Selenium and the current tools, we should investigate the central matters or advantages of Selenium and why it is a decent device for automation testing:
Open Source: Selenium is open source, this implies that no permitting or cost is required, it is absolutely allowed to download and use. This isn’t the situation for some, other automation devices out there.
Imitate User Actions: As expressed prior, Selenium WebDriver can copy client contribution, in genuine situations, you can automate occasions like key presses, mouse clicks, drag, and drop, click and hold, selecting, and much more.
Simple Implementation: Selenium WebDriver is known for being an easy-to-use automation device. Selenium being Open Source implies that clients can create augmentations for their own requirements.
An instrument for each situation: As referenced prior, Selenium is a set-up of tools, and you will no doubt discover something that accommodates your situation and your method of working.
Browser, Operating System, and Device support: Selenium upholds various programs Chrome, Firefox, Opera, Internet Explorer, Edge, and Safari just as operating systems (Windows, Linux, Mac)
Framework Support: Selenium likewise upholds a huge number of systems like Maven, Junit, TestNG to make it simpler to automate testing. CI and CD instruments like Jenkins are likewise upheld, for automating the deployment cycle.
Reusability: Scripts composed for WebDriver are cross-program viable. Testers can hence run numerous testing situations with a similar base.
Community Support: The Selenium people group is very dynamic and open. In this way, there is a ton of data and help accessible when required.
Advanced User Input: With WebDriver it is feasible to demand to click of the browser back and front catches. A commonsense element when testing money transfer applications for instance. This element isn’t found in numerous tools, particularly open source.
What might occur if Selenium unexpectedly declared it’s going the paid course? It’s difficult to study something when it’s given to you totally free, however, how excruciating would the traps be on the off chance that we out of nowhere needed to pay for them?
Selenium isn’t awesome yet it’s sufficiently useful for testers to invest more prominent energy and overlook the codeless pattern. It hits that sweet spot when you’re set up to put in a couple of hours searching for an answer online as opposed to getting the assistance you paid for. It actually has a couple of secret weapons that fit right in with the present designing account: quicker delivery, coming in little segments to deal with effectively, getting prompt feedback.
Selenium is a general use case. It doesn’t dominate the entirety of the other test automation tools, particularly on the off chance that you have the financial plan for them. In any case, its cornering nature makes you reconsider before you look the alternate way. Maybe, it isn’t so awful.
