Top 6 Programming Languages for Automation Testing

programming language for automation testing

No doubt At present, automation testing is on-trend and replacing the traditional Manual Testing practices within software organisations.

Starting from medium-sized companies to software tech giants, all have already implemented this modern way of testing cycle into their software development process. Compared to manual testing, it is more efficient and performs better with a low operational cost. It is the reason behind gaining its popularity with software companies.

Automation testing is a functional technique for testing applications. It is the process of executing a test on a program and recording the results. Once the application is over, automation testing is performed on top of it to determine whether unexpected actions can be avoided or discovered. It enables the software development team to mock up the existing logic in their target system (where automation tests are applied) and test their code before deploying it in production. 

The use of computing power, automation and databases help to reach stability & high quality in software projects. 

Automation testing checks the reliability and correctness of applications that need different programming languages. All programming languages have a peculiarity, and one should be aware of them before starting automation testing. 

Are you building your career in automation testing with a single programming language?.

If so, then it’s high time for you to start learning other programming languages. Because as a software tester, you should have a proper understanding of other languages used in software automation testing. There are several programming languages used for automation testing, but only a few are frequently used.

Let’s know about these top programming languages that are most suitable for automating software test cases.

As compared to other programming languages used in automation testing, the learning curve in python is easy due to its language readability. Moreover, it’s more portable and has several libraries that make the job of the developer easy as they help in performing actions without writing new code repeatedly for every task. But they need to have an idea to implement the codes in the right section to make the test script run successfully. Additionally, it has a healthy, active and supportive community.

Selenium and Appium testing libraries for Python make the job of automation testing and cross-browser testing on desktop and mobile devices easy.

To date, nearly 2.5 million websites have accepted the python framework globally.PyTest, PyUnit, Testify, and Nose2 are some of the popular testing frameworks that are used for selenium automation testing.

#2- Java:

Java comes next to our list of programming languages for automation testing. It is in top priority for organisations planning to create job opportunities in the field of automation testing.

It’s a general-purpose programming language owned by the Oracle Corporation and is mostly preferred by software tech giants for automation.

As per a report, more than three billion devices are based on java applications.

Several organisations use this programming language to maintain their back-end systems. It is one of the popular automated programming languages used in the IT industry as it has plenty of readily available frameworks, plugins, APIs and libraries. Around 77% of selenium testers use java which makes knowledge sharing easier and quick. 

It makes use of a Java virtual machine(JVM) that enables computers to run java programs along with programs written in other languages that are also compiled to java bytecode. Additionally, Java is statically typed, and its IDE gives feedback to testers that they might face while coding. 

If you are stepping into your career in test automation, it becomes the most essential for you to learn this programming language to run proficient test scripts.

#3- C#:

The Microsoft-created C# is also a trending programming language for automation testing. C# is designed on the concept of object-oriented programming and is one of the popular languages using the .NET framework. 

As per a survey report by Stack Overflow Developer(2022) 63.39% of all respondents consider C# to be the most loved programming language for test automation, web development, and more.

This programming language for automation testing is convenient for applications based on windows, android, and iOS platforms. 

Day by day it is gaining popularity in the space of test automation. Many software testers love to use C# for automation testing and cross-browser testing, due to its compatibility with selenium WebDriver. Testers can come up with an efficient and maintainable test code by using page object model(POM) design patterns.

Apart, there is no point in confusion while creating test scripts with C# as it can efficiently handle all the limitations remaining in the business modules with much effectiveness.

There is a wide range of automation testing frameworks available in C#, that help in Selenium testing and automated browser testing. This is the reason behind, the software tester considering C# for the development of test cases related to cross-browser testing. Some of the most used test automation frameworks in C# are NUnit, MSTest, and xUnit.Net.

#4- JavaScript: 

Our list of programming languages used for automation testing will look incomplete without including JavaScript. It’s a great programming language for automation testing mostly used for front-end development. As per a survey report by Stack Overflow Developer(2022) 73.46% of all respondents consider JavaScript to be the most loved programming language for test automation, web development, and more. There are several web applications like Instagram, Airbnb and Slack that support libraries written through JavaScript automation like ATOM, Botkit, and Mavericks.

Apart from front-end development, it is quite popular for automation testing. There are several testing frameworks like Zest, Jasmine, and Nightwatch JS which filter different processes of unit testing including end-to-end testing.

The primary reason behind its popularity in test automation is that the developers can build strong web applications majorly focusing on the core logic of businesses and quickly resolving security-related concerns which may occur at any point in time. As a result, the team working on automation testing doesn’t get pressure as the debugging time and other code glitches are reduced and the productivity gets increased with the shift-left testing approach. This approach is most important in the development process as the testing team works closely with the development team. 

Developers even prefer to use JavaScript with Selenium for test scenarios related to automated browser testing. Along with that, it is used with remote Selenium Grid like LambdaTest without major changes in the source code.

Some of the widely used JavaScript test automation frameworks are Jest, Mocha, Nightwatch JS and Jasmine.

#5- PHP:

PHP is one of the popular open-source programming languages commonly used for server-side development. It is even used as a programming language for automation testing.

PHP is a widely used automation programming language used by over 34 million websites. Popular global websites like Facebook, Yahoo, tumbler, and more are using PHP. 

As per a survey report by Stack Overflow Developer(2022) 41.61% of, all respondents consider PHP to be the most loved programming language for test automation, web development, and more.
