Automation Testing is undoubtedly flourishing in the current times by replacing the traditional Manual Testing practices within organizations. All this is happening as automation testing is somehow less labor-intensive, more efficient, and scalable compared to manual testing along with offering better performance and less operational costs. Automation Testing is basically concerned with the process of using various tools and software to create test cases and their execution by considering pre-defined actions. Moreover, MarketsandMarkets has also confidently predicted in its report that the automation testing market will cross 28 billion US Dollars by 2024.

Top 5 Programming Languages for Automation Testing


You could think about writing your own automation testing journey with a single programming language! If this is so, then it’s high time to note the fact that to build a career in automation testing, you’re required to have a sound knowledge of the relevant Programming Language. You need to mix up well with the ins and outs of the programming language used in Automation Testing. 

There are various languages out there that you can consider for automation testing such as Python, C#, etc. Let’s take a look at the top five languages:

1. Python

Python is an open-source programming language popularly supporting automation testing. Moreover, it supports a number of frameworks for unit, end-to-end, and integration testing which are somewhere associated with automation. Even its code can be learned easily and anyone who aspires to acquire a hold over this language can extensively apply a combination of codes in a flexible manner. To date, more than 2 million websites have globally accepted Python frameworks, which are PyTest, Robot, Nose 2, Behave, Lettuce, and Testify. 

Many of them can be installed with minimal effort so that the websites or applications supporting them may perform business tasks concurrently and parallelly (both). For businesses, getting started or will start later, they must hire Python developers who know when and how to perform the right actions without writing newer codes again and again for every task. But the owners need to keep in mind the fact that the code implementation is done in the right section, thereby making the test script/scripts run successfully.

2. JavaScript

JavaScript focuses strongly on test automation and performs well when it comes to rebranding client-side expectations through front-end development. Unavoidably, there are many web applications like Instagram, Accenture, Slack, and Airbnb which support libraries written through JavaScript automation, such as instant, ATOM (Accenture Test Automation Open source Modular Libraries), Botkit, and Mavericks. Besides, there are various testing frameworks like Zest, Jasmine, and Nightwatch JS which refine multiple processes of unit testing as well as end-to-end testing. 

The reason for using them is that programmers or developers may build strong web applications primarily focusing on the core logic of businesses and quickly resolving security-related issues that may occur anywhere and anytime. With such advantages, teams working on automation testing won’t feel pressured because the debugging time and other code glitches are reduced and productivity is promisingly increased with the shift-left testing approach. This approach is essentially important in the testing code development process as the testing team will be working closely with the development team with the sole purpose of implementing precise plus efficient test automation without changing the source code in actuality.

3. C#

C# Programming language is supported by more than 60 percent of users in a survey of StackOverflow when it comes to fulfilling the development and automation requirements of a business venture. Developed by the experienced developers of Microsoft, C# is steadily flourishing its boom with its automation testing frameworks. They are xUnit.Net, NUnit, and MSTest. Through them, many automation testers can perform cross-border, unit, and functional testing so that consistency and extensibility during code execution are strictly maintained. 

Indeed, companies like Accenture, Stack Overflow, and Intuit prefer adopting C# as it is explicitly compatible with Selenium WebDriver (a framework that permits the execution of cross-border tests in a verified way). Also, there is no room for confusion while creating test scripts with C# as it can faithfully handle all the limitations lying in the business modules with much effectiveness. What businesses need to do is unite this structured programming language with their processes of automation testing and use the tested business applications (supported by C#) on platforms like iOS, Windows, or Android.

4. Ruby

Ruby is another MVC Architecture-enabled programming language spreading its wings in organizational areas demanding automation. Those areas may either be related to recruitment, compliance, logistics, or risk management. Another interesting thing about the Ruby language is that it can potentially create a convenient working environment for Selenium Automation Testers so that they may implement cross-border testing and its connected processes by writing less LOC, i.e. Lines Of Code. Assertively, the language is human-friendly and backed by simplicity and productivity. 

With its popular frameworks like RSpec, Capybara, and Test::Unit, companies like Twitter and Shopify are able to deploy web applications inclining towards automation. So, small or large-sized ventures need not think about whether their teams are able to cover expenses or save time while reusing the test suites. This is because the syntax of Ruby can impeccably be utilized for documenting test cases 10x faster without modifying real-time reports in multiple instances.

5. Java

Java is the next top priority of the bigger organizations planning to create more and more job opportunities in the field of automation testing. With the general-purpose Java code(s) owned by Oracle Corporation, more than 2 billion devices are able to synchronize a plethora of automation benefits backed by the ‘Write Once, Run Anywhere’ principle of this multi-purpose language. Also, the JUnit framework can be implemented well into the test scripts of Selenium Web Driver so that the browser applications may send and accept commands robustly. Apart from all this, well-reputed companies like Netflix, Google, and Pinterest have employed Java in information sources, plugins, and web applications professionally, letting their teams align well with the product development stack they have brought to market. This is real wealth in terms of the driving force, as UI checks and their associated elements are accurately validating the performance in an overwhelming and error-free way.


So these were the top programming languages that can be used for automation testing and help in doing the work at a fast pace. You can choose according to your need and work in a more efficient manner. These automation testers are more effective than manual testing thus making the work easier.
