Top Programming Languages for Automation and Testing in 2021

Top Programming Language for Automation and Testing in 2021

In today’s highly competitive world, software development and automation play a significant role in creating robust software applications for businesses. Additionally, emerging technologies like Artificial intelligence, blockchain have given a competitive edge to enterprises.

There are numerous programming languages available for automation testing. Sometimes choosing the right platform becomes difficult for developers, so we’re here with the top 10 best programming languages for automation testing in 2021.

Automation Testing may be a software testing technique that uses special automated testing software tools to perform a test suit suite. Manual Testing is performed by human intervention where an individual is sitting ahead of the pc and executing the test steps.

Testing automation software can enter test data within the System Under Test and generate detailed test reports and actual results. In this blog, along with a programming homework service, we’re going to discuss the top 10 programming languages which should be taken into consideration for test automation in 2021. So, with none further ado, let’s get started!

1. C#

C# is created by Microsoft. It is considered one of the simplest automation programming languages. 67% of the users, as reported by Stack Overflow Developer Survey, prefer C# for their development and automation needs. C# has shown a gradual growing trend as a test automation language. There are many test automation frameworks in C# NUnit, MSTest, and xUnit.Net support automation and cross-browser testing.

2. C/C++

A unified testing tool with deep integration into the developer’s IDE provides the foremost productive environment for development testing. A unified tool, like Parasoft C/C++test, enables teams to focus their testing on high risk, and most recently modified code.

3. PHP

Hypertext Preprocessor may be a widely used command-line, server-side scripting language used for web development and test automation. It is most commonly used for mobile applications that require database access. More than 34 Lac live websites use PHP as their preferred Automation programing language. Organizations like Wikipedia, Facebook, and Yahoo use PHP for their website. PHP supports the development of e-commerce websites, content-heavy and dynamic web and mobile apps.

4. JavaScript

JavaScript, accounting for 15% of our customers. With its overwhelming popularity with developers, it’s no surprise that Javascript is the second most used language for test automation and also the fastest growing. With Javascript being used by 72% of professional developers, many teams choose this language for their test automation projects as well. This can flow from to the adoption of shift-left methodologies where developers also are liable for writing test code, or thanks to the testers’ desire to “speak an equivalent language” of their developers. Some find this alignment helps with collaboration efforts around test automation.

5. Java

Java is a general-purpose programming language for automation testing. More than 40% of customers are using Java for their automated checks and the wealth of readily available education resources, plugins, and frameworks that support Java for test automation. This shows that the narrative that insists that community support is a driving factor when choosing a programming language for test automation.

6. Ruby

Only 4.2% of our customers use Ruby for test automation. This is a stunning 40% decrease from Ruby test automation usage last year. StackOverflow shows Ruby’s popularity down to 8.9% with professional developers and it appears Ruby is even less popular in the testing space.

7. VBScript

VBScript is a programming language developed by Microsoft. VBScript is the lighter version of Visual Basic so both use similar syntax. It is utilized in Quick Test Professional (QTP), an automatic functional testing tool for coding and executing automated tests. If a tester wants to figure out QTP, he must know VBScript.

8. Perl

Perl has been used for years in QA for various tasks such as preparing configuration files before the tests run and parsing log files after the test. In the past few years, lots of extensions have been added to Perl. Now, additionally to the above tasks, Perl can already be utilized in all parts of the automated test environment.

9. SmashTest

SmashTest is an open-source language that creates a rapid generation of test cases. It is 10x faster and easy to understand compared to other programming languages. Smash Test offers powerful tools and resources for automation testing and makes it enjoyable for you if you would like to dabble with test automation.

10. Python

Right behind C# is Python, with 8% of our customers using Python as their language of choice for test automation. This is precisely the same percentage of usage we saw last year. Python is gaining popularity year after year with professional developers and has become the fastest-growing major programming language – even edging out Java for the first time this year! Perhaps we’ll eventually see this trend in software testing also.


The data above explains the recent best automation programming languages for test automation that have a bigger user base. However, the trends keep changing with time. Apart from the above-mentioned languages, many other growing programming languages are often considered while making a choice. The choice of programming languages differs from organization to organization and depends on the testers. May you learn any programming language to make your testing ability stronger, but the main aim is to automate the test completely, detect and report errors in advance, without human intervention, and be ready to create reusable tests.
