The 8 Best Programming Languages for Automated Testing in 2021

As we all know, there are numerous programming languages available for test automation. Sometimes choosing the right platform becomes difficult for developers, so we’re here with the top 8 best programming languages for automation testing in 2021. 

What is Automated Testing?

Automation Testing is a software testing technique that uses special automated testing software tools to perform a test case suite. Similarly, Manual Testing is performed by human intervention where a person is sitting in front of the computer and executing the test steps.

Testing automation software can also enter test data within the System Under Test and generate detailed test reports and actual results. It demands considerable investments of money and resources.

A successful development cycle needs the execution of the same test suits again and again. Using a testing automation tool, you can record this test suit and re-play it as required. When the test suite is automated, there is no requirement of human intervention which proves the ROI of test automation. Automation testing aims to reduce the number of test cases and not to avoid Manual testing altogether.

There are numerous programming languages for test automation which makes it difficult for you to choose the right one. So, to ease your work, you can contact some reliable companies like Tatvasoft, iCoderz Solutions, Science Soft, and so on. They won’t just guide you in choosing the best programming language but also help you to empower your business for next-gen applications. 

Parameters to Consider While Selecting Programming Language

There are eight parameters to take into consideration while evaluating any language for automation, which are as follows:

  1. Elegance: It is the process of translating the test cases into code to make them easy and clear. Make sure that the test cases are concise and self-documenting for maintainability. 
  2. IDE Support: make sure that it supports IDE because vim and Notepad don’t cut it for big projects.
  3. Usability: A perfect automation language should handle rote tasks such as memory management and must be high-level. Low learning curves are recommended.
  4. Available Packages: It is better to use readymade packages for basic operations such as SSH, HTTP requests, and web drivers. 
  5. Industry Adoption: If the automation language remains popular, then development frameworks and packages will be maintained well. 
  6. Available Test frameworks: It provides basic requirements like reporting, fixtures, cleanup, and logging, 
  7. Powerful Command Line: Powerful CLI is mandatory to launch the test cases easily and for continuous integration. 
  8. Easy Build Integration: Make sure that the automation launch tests and report results.
