The State of Selenium Testing in 2023

Manual testing is an essential step in the development of applications, but, we all know that it has plentiful drawbacks. The test cases are manually conducted in manual testing. The test results are compared with the anticipated or intended result. The difference between the intended and actual results then suggests that there is a flaw. To make sure the programme is error-free, this flaw is addressed. As you can see, the process sounds very tedious and repeated. Developers find it really monotonous! Apparently seeing all these difficulties,  Jason Huggins, an engineer at Thoughtworks, made the decision to automate the testing procedure. He created the JavaScriptTestRunner, a JavaScript programme for automating web application testing. In 2004, the program’s name was changed to Selenium. Today, Selenium Testing has become a benchmark in the software testing industry, thanks its easy-to-follow process!

Some of the problems with manual testing have been resolved by Selenium automation testing. The term “automated testing” describes the process of putting new software, applications, and systems through their paces using testing software and automation tools. By using this method, testers may determine if the software or app includes any flaws. Additionally, it also allows developers to evaluate the efficiency and functionality of these programmes.

Selenium is used for automated testing of new software or application. This programme offers a framework for online application testing, across different web platforms and browsers. Since it is open-source, developers are not required to pay any licencing fees, which makes it even more desirable!

When compared to manual testing, Selenium executes automated testing faster. Additionally, it offers a number of tools that broaden the test’s reach. The test cases are run automatically in this kind of automated testing, which raises the accuracy level. Java, Python, C#, Perl, Ruby, and PHP are a few of the programming languages used to create text scripts with Selenium. Various browsers, including Apple Safari, Mozilla Firefox, Internet Explorer, and Google Chrome, are supported by this programme during testing. On other operating platforms, including Linux, Windows, and Mac, automation testing in Selenium may also be carried out.

Before we dive into the state of Selenium testing in 2023, let’s first get our basics clear!

What Is Selenium? Let’s Begin Here!

To put it simply, Selenium is one of the best tools out there for end-to-end testing. It is an open-source automation framework. It is widely used to test a variety of cloud computing platforms as well as browsers. Numerous programming languages, including Ruby, Java, Python, and JavaScript, are supported by Selenium for the creation of test scripts. Selenium functions as an integration of tools. The components of Selenium include, firstly, Selenium Grid (a server that enables parallel script execution on remote machines), secondly, Selenium IDE (a browser plugin for recording and replaying tests), and thirdly, Selenium WebDriver (a collection of APIs for testing web apps across browsers). We will shed light on all of these components of Selenium in the next section of the blog!

Selenium has developed a lot in the recent years. Automation engineers can now create browser-level automated regression test scripts using Selenium. These test scripts can be easily scaled across many settings and browsers. Apart from this, they can also create scripts that imitate a user’s interaction with web browsers, even those accessible from mobile devices, using Selenium’s WebDriver API.

End-to-end tests that use Selenium can alter the Document Object Model (DOM). This is typically done to validate which components are presented to users while simulating user input and interaction, or modelling a user journey in an application. For example, a script that checks sign-up, sign-in, a product search, add to cart capability, product review views, and checkout logic may be included in an end-to-end test scenario for an e-commerce platform.

You can harness the full potential of Selenium testing by utilizing cloud-based platforms like LambdaTest. As a digital experience testing platform, LambdaTest offers a reliable and scalable cloud infrastructure for executing Selenium tests. It seamlessly integrates Selenium with popular CI tools such as Jenkins, Travis CI, CircleCI, and others.

With LambdaTest, you gain access to over 3000+ testing environments, including real devices, allowing comprehensive testing of your website. Setting up your Selenium tests to run as part of your CI process is effortless and ensures faster and more dependable deployments. Additionally, LambdaTest provides the convenience of automatically capturing screenshots and videos of your test runs. This feature facilitates easier analysis and debugging of test results.

Selenium Components

As mentioned above, in this section of the blog, we will have a detailed look into the various components of Selenium.

• Selenium Grid

Selenium Grid was created by Patrick Lightbody. He did this with the intention of reducing  the execution time of Selenium automation testing. Selenium Grid facilitates parallel execution by enabling test execution across several browsers and operating systems. The Grid is very adaptable and integrates with other elements of the suite for concurrent performance. It is made up of a hub and multiple linked nodes. Along with the test to be done, it also collects data about the operating system and browser that will be used. The Grid then selects a node and passes the test to that node if it complies with the specifications (browser and platform). At this point, the node launches the browser and carries out the Selenium instructions inside of it.

• Selenium WebDriver

Selenium WebDriver was developed by Simon Stewart in 2006. It basically worked like a programming interface to design and execute test cases. It was the first cross-platform testing framework capable of configuring and managing browsers at the OS level. In contrast to Selenium RC, WebDriver works directly with the browser apps and it does not require a core engine like RC. Not only this, WebDriver supports a number of programming languages, including Ruby, Perl, PHP, and Python. Selenium Webdriver can also be incorporated with frameworks like Junit and TestNG for managing Selenium automated testing.

• Selenium IDE

The Selenium Integrated Development Environment (IDE) or commonly known as the Selenium  IDE was created in 2006 by Shinya Kasatani. It is a Chrome or Firefox plugin that is often used as a prototype tool. It was primarily created to facilitate the rapid development of automation scripts. Selemium IDE is a simple user interface that logs user interactions so that automated test scripts may be created.

When Firefox switched to the new Firefox 55 version, which did not support Selenium IDE, IDE ceased to exist in August 2017. A new version of the outdated Selenium IDE was been published by Applitools. The most recent version included various improvements like:

• Script reuse was allowed for tests
• Debugging of test scripts
• Selenium side runner
• Provision for control flow statements
• Enhanced locating capabilities

Step By Step Process To Start With Selenium Automation Testing!

In this section of the blog, we will look at some steps to get started with selenium automation testing!

• Step 1: Get Selenium WebDriver installed

Configuring Selenium WebDriver for your chosen programming language is the first step. For instance, you can go ahead with downloading the Java WebDriver from the Selenium website incase you are using Java. The Selenium package may be installed via pip if you’re using Python. You can find a tonne of materials online to help you with this procedure.

• Step 2: Select a suitable testing framework

You can utilise a variety of testing frameworks that works well together with Selenium. JUnit,  NUnit and TestNG are a few of the well-liked ones. These frameworks offer you a way to organise your tests and produce reports. Pick a framework that works for you, then get to know how to utilise it.

• Step 3: Build a test project

In this step, for your Selenium tests, you will have to create a new project in your development environment. The Selenium WebDriver as well as the testing framework you selected in step 2 both need to be imported in this stage. You must make a new test class that extends the base class of the testing framework.

• Step 4: Writing your first test

You will write your first test case for your test class in this stage. In this situation, you should access a web page, do certain activities, and then make sure the desired outcomes are presented. Open the Google homepage, for instance, type in a search query, and check to see whether the results page appears.

• Step 5: Execute your test

Make sure your test succeeds before running it. Debug the test by looking at the code and error message if it fails. Run the test once again after fixing any problems.

• Step 6: Keep writing more and more tests

In this stage, we will suggest that you write more tests by repeating steps 4 and 5. To cover a variety of situations and use cases, add additional test cases. You should categorise the tests into test suites and groups as you continue to add additional tests.

• Step 7: Now it is time to create reports

The majority of testing frameworks include integrated reporting features that provide HTML reports with test results. Utilise these reports to monitor the status of your test and spot any problems.

• Step 8: Integrate using continuous integration

Use a continuous integration programme like Jenkins or Travis CI to integrate your Selenium tests. Every time you submit new code to your repository, this will automate the testing process and execute your tests.

Let us tell you that Selenium is a strong tool for automating web browser testing. It may sound a little complicated but you can easily create and develop automated tests for your web apps with a little setup and some coding knowledge.

The State of Selenium Testing in 2023

The Informational Technology sector is very competitive, and as technology is always evolving, one must stay up-to-date! Selenium has evolved too. Starting from a mere idea, today, it is  well known that the web development or the software testing industry has implemented Selenium automated testing extensively. Selenium tool is used in almost all testing processes in organizations that operate online via websites or web applications.

It is noteworthy to bring to your attention that Selenium is a framework not only for test automation. It works seamlessly with many different programming languages too. Testers may easily automate the unit testing process. Even DevOps teams make use of Selenium in their CI/CD technologies to guarantee a thorough cycle of browser automation testing each time a code change is submitted across the pipeline from one stage environment to another. UI developers may utilise Selenium for visual regression testing after each integration. Selenium allows even independent developers to conduct tests for troubleshooting. With Selenium, QA engineers can guarantee deterministic scripts and tests with increased accuracy and coverage.

Selenium is an open-source framework and trust us when we say that it provides many independent web developers and testers with a lifeline.

Organisations and web developers all over the world use Selenium to test online applications. The following are a few of the explanations for why this programme is so widely used in automated testing.

• Installing and using this programme is quite simplistic.
• As mentioned before, because this programme is open-source, licencing and testing are less expensive.
• This programme may be used with other programmes like TestNG, Docker, Maven, and Junit. These programmes improve automated testing, particularly test management.
• The hardware usage for script execution is minimal.
• Selenium also offers a large public forum for client help.
• Selenium is flexible! It supports a variety of programming languages, browsers, and programming languages. Web developers now have freedom thanks to this. This contrasts with other testing tools like Relational Functional Tester (RFT) and Quick Test Professional (QTP), which only support a select few browsers.
