Best Programming Languages for Qa Testing in 2023

The best programming languages for qa testing are java and python, due to their versatility, reliability, and ease of use. In the world of software development, quality assurance (qa) plays a crucial role in ensuring that applications are tested and evaluated before they are launched in the market.

As a qa tester, selecting the right programming language is incredibly important for successfully running automated tests and debugging failures. While there are many programming languages available, including c, c++, javascript, and more, the two most widely used programming languages in qa testing are java and python.

Java is popular for its easy-to-learn interface, excellent tool support, and efficient object-oriented programming capabilities. Python, on the other hand, is known for its versatility, simplicity, and ease of use.

In this article, we will explore the benefits and drawbacks of these two programming languages for qa testing and help you choose the best option for your specific needs.


Object-Oriented Programming Languages

Object-oriented programming languages (oop) are programming languages structured around the concept of objects. Oop languages are designed to represent real-world objects, their properties, and actions. As a result, oop languages are more modular, scalable, and reusable than other types of languages.

Benefits Of Using Oop Languages In Qa Testing

Using oop languages in qa testing provides several benefits such as:

  • Encapsulation: Oop languages provide encapsulation that helps in hiding the complexities of code and making it easier for developers to maintain it in the long run.
  • Inheritance: Inheritance is one of the principal concepts of oop languages that helps in reusing the existing code and saves time, effort, and resources.
  • Polymorphism: Oop languages provide polymorphism that helps in writing efficient and concise code, as the same code can be used to handle different object types.
  • Better code organization and readability: Oop languages make it easier to organize the code logically, making it more readable and understandable. As a result, it helps in better collaboration among team members.

Top oop languages for qa testing – java, python, and ruby

  • Java: Java is one of the most popular oop languages used for building software systems. It’s used for developing enterprise-level applications for desktops, web, and mobile platforms. Its vast community support and cross-platform compatibility make it an ideal choice for qa testing.
  • Python: Python is another widely used oop language that is easy to learn, read and write. It has a vast library of modules, making it an ideal choice for scientific computing, web development, and machine learning applications.
  • Ruby: Ruby is an oop language popular for web development, automation testing tasks, and data processing. It is highly flexible, easy to read, write, and maintain, making it ideal for agile projects.

Oop languages provide various benefits to qa testing and simplify the process of software development. Java, python, and ruby are among the top oop languages frequently used in the qa testing of software.

Scripting Languages

Understanding Scripting Languages

Scripting languages form an integral part of quality assurance testing. They are high-level programming languages that require minimal coding, as they mainly deal with automation, data extraction, and data manipulation tasks. With scripting languages, it’s easy to automate repetitive tasks, thus freeing up time, improving accuracy, and reducing errors.

How Scripting Languages Are Different From Oop

Unlike object-oriented programming languages, scripting languages tend to operate on data only. They do not create and utilize tightly coupled object structures, but instead, work with independent variables and functions. Also have a syntax that simplifies data manipulation tasks, thus making them ideal for qa testing.

Here are the top scripting languages for qa testing:


Javascript is an essential scripting language in qa testing for a reason. With its flexible syntax and functionality, you can develop powerful web-based applications, automate web tasks and perform quick data validations. The support libraries and frameworks like angularjs, nodejs, and jquery make qa testing with javascript a breeze.


Perl is popular in qa testing for its robust text manipulation capabilities. It has built-in regular expression support, allowing you to quickly validate and manipulate strings, thus making data parsing and extraction a breeze. Perl is a dynamic language, and it can work well with other programming languages, providing a high level of functionality and flexibility.


Shell scripting is a powerful qa testing tool for automating tasks on operating systems such as linux and unix. Shell scripts are text files that contain a series of commands that an operating system can execute. They allow you to automate system administration tasks, run tests, and perform batch operations with ease.

Shell scripts are particularly useful for testing web applications with apis, as they can be used to automate api testing.

Overall, scripting languages are essential in qa testing, and the above three are the top scripting languages you can use to automate tasks and maximize efficiency in test automation.

Functional Programming Languages

Functional programming languages have become popular in the world of software engineering due to their focus on immutable data and pure functions. These languages use mathematical concepts to create efficient and reliable programs that are easy to test and maintain.

In this post, we’ll explore the definition and benefits of functional programming languages in qa testing, and then introduce you to the top functional programming languages for qa testing – haskell, scala, and erlang.

Definition Of Functional Programming Languages

Functional programming languages are those that emphasize the use of functions and immutable data structures. In these languages, values are fixed and cannot be changed once they are created. The functions in this style of programming are pure in the sense that they do not have any side effects on the system, making them easier to test and debug.

Functional programming languages are often used in applications where correctness is critical, such as in scientific calculations, finance, and qa testing.

Benefits Of Using Functional Programming Languages In Qa Testing

Using functional programming languages in qa testing can provide several benefits, including:

  • Easier to test and debug: Functional programming languages make it easier to test code because functions always produce the same output for a given input, making them predictable and easier to debug.
  • Less complex code: Functional programming emphasizes writing modular and reusable code, leading to less complex code that is easier to maintain over time.
  • Improved code quality: In functional programming, writing pure functions can help prevent side effects, leading to more reliable code that is easier to reason about.

Top Functional Programming Languages For Qa Testing

When it comes to functional programming languages for qa testing, three languages stand out: haskell, scala, and erlang.

  • Haskell: Haskell is a purely functional language that is designed for high-level abstractions and ease of writing concise and readable code. It is known for its strong type system and can help eliminate errors before they occur.
  • Scala: Scala is a functional and object-oriented programming language that has been gaining popularity in recent years due to its flexibility and expressiveness. It runs on the java virtual machine (jvm), which means it can integrate seamlessly with java-based systems.
  • Erlang: Erlang is a functional programming language that is designed for building distributed and fault-tolerant systems. It has built-in concurrency and process isolation, making it an excellent choice for developing reliable and scalable systems.

If you’re looking to improve the quality of your code, reduce complexity, and make your tests more reliable, then functional programming languages are definitely worth considering. With haskell, scala, and erlang, you have three great options for building high-quality software that will stand the test of time.

Compatibility With Automation Testing Tools
