Automation Testing can be defined as a set of software testing activities in which test cases are executed and produced results are compared with the expected ones with less human intervention. This is a better technique than manual testing because, with automation, the scope of generating errors is assertively reduced as repetitive work (during the test case execution) is identified and successfully eliminated. Henceforth, many software testing organizations are inclined towards the need and demand for Automation Testing tools for building applications at improved accuracy and higher test coverage. 


Curious to know about the best Automation Testing tools, marking the essence of aspects like Continuous Integration and Continuous Deployment of testing activities successfully bridging the gaps between the technical and business teams within an organization!! Here is your curated list of AT i.e. Automation Testing tools that you can consider in 2021 and in the coming years.  

1. Selenium

Selenium is an outstanding open-source ATT i.e. Automation Testing Tool. Even its test scripts can powerfully scale across variable computing environments supported by multiple browsers. Most often, this ATT shows real-time compatibility with various frameworks and programming languages, nodding their heads towards Automation Testing. To date, more than 52000 multinational corporations (inclusive of ZenDesk Inc, Penguin Random House LLC, The American Red Cross) are using Selenium for automating testing conducted across Web Browsers like Mozilla, Safari, Firefox, and Chrome. Doesn’t matter if you are a pro or a beginner at Automation Testing – Selenium will greatly be helping you to produce a reproduction of bugs, exploratory, as well as regression testing!! And all this is possible with its striking features supporting parallel test execution, thereby reducing test execution times with its helpful and advanced automation scripts.

2. Ranorex

Ranorex is your all-in-one (and will always be) Automation Testing tool either for web, mobile, and desktop application testing. If you are a beginner in the field of Automation Testing and looking desperately for some codeless click-and-get-through interface, this tool with its dynamic IDs and reliable object identification will let you perform both – cross-platform and cross-browser testing. This is because clearly defined objects used in writing or debugging automated test scripts will be deriving meaningful test results for sure by easily maintaining the codes. Henceforth, this ATT is trusted by more than 4000 corporations worldwide willing to customize or re-use their existing code modules with this commercially licensed tool. If you are planning to integrate its shareable repositories with tools like Git, Jira, or Jenkins, then this can be done flexibly with no compromise on the efficiency of your web-based applications handled with easy script maintenance.

3. Kobiton

Kobiton is another powerful and cloud-based AT platform that has enabled the testers to work closely with mobile devices plus performance application testing. With its scriptless test automation solutions, many companies are extensively able to conduct a variety of device testing for creating flawless visual experiences on all types of devices. This is the reason why this platform is renowned as an award-winning pixel-perfect application powered by Artificially Intelligent Crash Detection methods. Seamlessly, its CI (Continuous Integration) and CD (Continuous Development) functionalities support frequent code changes reliably and precisely so that the applications can be delivered to its customers along with automation embodied principally. Moreover, the in-depth session exploration and reporting offered by this AT platform (with enabled integration with Jenkins, TeamCity, and GitHub) simultaneously focus well on test designs and their associated execution so that the defects still not explored at the early stages of Automation Testing can easily be covered with less guidance.  

4. Cucumber

Cucumber is that open-source Automation Testing tool primarily employed with Behavior-Driven Development. Indeed, the tool has been added to the list of Testing Frameworks of more than 120 companies (some of them are named as CraftBase, BitPanda, Kaidee, Aircall, MAK IT). You may think about how this tool is Behavior Driven? And the answer is – Cucumber is allowing the business analysts or testers to create test case scenarios (in simple English i.e. Gherkin) that will let the non-technical panel members understand what exactly is going on in their software projects? With such accelerated development, the gap between technical people and business individuals is somewhere abridged as they may now align well with the living documentation of this Ruby-scripted tool always supporting cross-functional and team-centric workflows. Apart from all this, the tool offering faster premium support can scalably be integrated with other testing tools like LambdaTest, qTest Management, Karate DSL, Experitest, Database Rider, and a few more.  

5. Eggplant

Eggplant (deployed and developed by TestPlant) has offered endless possibilities of solutions by offering business-focused metrics. With those metrics offered by this licensed tool consisting of Digital Automation Intelligence, the testers may access the reports’ monitoring, tracking, and assess the failure or success of testing processes contextually revolving around quantifiable business items like interest cost, product returns. Undoubtedly, the scriptless models supported by this automated platform (that may be visualized as a collection of tools responsibly handling performance, functional, GUI, and application testing) are letting the testers do validation and execution of test-cases in an approach-oriented scalable manner. Also, such a collection of tools can feasibly perform testing on Linux, Mac, and Windows, thereby encouraging business ventures to invest in those tools whose cross-platform applications are likely to reach more and more people. Besides, this platform offers successful integration with Jenkins, HPE Quality Center, IBM Rational Quality Manager with no complete elimination of scripting.

6. Appium

Appium is also your open-source AT Tool whose server-based architecture is intended towards applications of Android and iOS. Since it uses a standard API, the code created through this tool doesn’t demand much recompilation or modification. With this specification, the tool has gained the utmost popularity as well as stability in this current testing market. Thinking about whether this tool supports various types of mobile applications!! Yes, it does support hybrid, native, and mobile web applications which invites lesser use of SDK, i.e. Software Development Kit. Furthermore, this tool (preferably recognized as a framework by many automation companies) can potentially automate any mobile application from any of the programming languages like Java, Ruby, C#, JS, or PHP. Even at times, testers need to record gestures of code scripts, they may use Appium (which can be integrated with CI/CD tools like TeamCity, CodeShip, Jenkins, Bamboo) from their tool belt and use its recording feature somewhere supporting cross-platform testing.  

7. Katalon

Katalon can usefully depict automation frameworks of Appium & Selenium for better analysis and recording of test scripts. When it comes to BEING VERSATILE, Katalon never leaves a stone unturned while performing on Operating Systems like Linux, macOS, Windows. Depending upon the testing skills of testers, this easy-to-deploy tool (with a single installation package) can smoothly be integrated with Slack, Git, JIRA, qTest, and Kobiton. Recently, this is recognized as a Gartner Peer Insights Customers’ Choice for the S/W Test Automation market because the ones taking up many queries with programming skills (i.e. have lesser proficiency with programming) can hassle-free execute and manage automation test scripts designed for web and mobile apps. Looking forward to getting started with an ALL-IN-ONE test automation tool!! You have a chance to access the A-to-Z features of Katalon, like the ability to speedily creating automation tests, capably performing web API, web, and mobile testing; flexible reporting, and test execution options.
