Choosing the Right Automation Testing Tool: A Guide

By :

Testing is an essential step in any Software Development Life Cycle (SDLC) aimed at confirming the product’s quality and eliminating errors to ensure the final product is free from defects. There are two testing methods: Manual testing and Automation testing. Manual testing involves testers meticulously following a step-by-step process to identify defects in the developed product. 

However, this approach often leaves little room for exploratory testing and reporting, particularly when Agile processes show no sign of decline. In contrast, Automation testing relies on predefined actions, produces consistent results, and generates intelligent reports, offering greater efficiency for both the organization and testers.

In this blog, we will delve into the critical decision of choosing the right automation tool. With a plethora of options available in the market, selecting the most suitable tool can be a challenging yet crucial task. We’ll explore the factors to consider and provide insights into some of the best automation tools that cater to web and app testing needs. Whether you’re a seasoned QA professional or a newcomer to the world of test automation, this blog will help you make informed choices, enhancing the effectiveness of your testing efforts. But before we go ahead, let us first understand the basics of automation tools. 

Why do we need automation tools?

Automation testing improves the efficiency of testing, ensures accurate results, and expedites the execution speed of time-consuming and repetitive manual tasks. The testing process in the SDLC gets completed with minimal human intervention which leads to faster sharing of results when the build is shared.

What are the benefits of automation?

Automated testing has benefits like higher reliability, availability, productivity, reduced operating costs, and increased performance.

How to choose the right automation tool?

There are many automation testing tools in the market and the new tool gets launched every year, some are open source and some are charged. How to choose the right tool for your project? Below are some tips that can help you make informed decisions:

  • Determine the scenarios to be automated.
  • Evaluate and investigate the automation options that suit you the best as per your budget and requirements.
  • Choose a couple of tools that suit your requirements.
  • Conduct test trials and choose the best one.
  • Share the information with the stakeholders and get their consent.
  • The selection and utilization of the most suitable tool depend on the project’s specific requirements, as there is no universal “best” tool for all projects.

The below-listed tools are some of the best automation tools that can be used for both web and app testing.

Popular tools in the market
  • Appium

Appium is a common open-source framework and a cross-platform tool that executes the test scripts in multiple platforms like Android, iOS, and Windows using the same API. Additionally, Appium provides support for multiple programming languages and automation testing frameworks, such as Java, JavaScript, Python, PHP, C#, and more.

Using Appium, you can conduct app test automation for the following :

  • Native mobile apps: These apps are written using Android, iOS, and Windows SDKs installed on the device.
  • Mobile web apps: Web applications can be opened in mobile web browsers such as Chrome and Safari. Additionally, you can access mobile web applications by utilizing in-app browsers on both Android and iOS platforms.
  • Hybrid apps: These applications are constructed with a wrapper around a “webview,” which is a native control enabling interaction with web content. You have the option to access hybrid apps either through a physical device or via a browser URL.


Katalon Platform is an automation testing software developed by Katalon, Inc. This software is built on top of the open-source automation frameworks Selenium, and Appium with a specialized IDE interface for web, API, mobile, and desktop application testing.

Katalon Studio is a low-code platform that has all-in-one for automation testing for web, API, mobile, and desktop (Windows). This tool has the following features that can help in speeding up the QA: 

  • Powerful Record and Playback: This is the simplest method for generating test cases in automation testing. It records the actions that you perform and converts them into an executable code in the back end. This functionality is particularly useful when the process of identifying objects is laborious and challenging.
  • Behavior-Driven Development (BDD): BDD is a testing methodology widely used in many agile teams. Katalon Studio supports Cucumber Runner for BDD and seamless integration with Jira.
  • Smart XPath: When there is an update in the application, it is difficult to fix the element location. Katalon Smart XPath leverages AI to automatically locate web and app elements, making it easier for you to adapt to the frequent changes that accompany each new release.
  • Smart Wait: This is a newly introduced feature in Katalon Studio 7 that handles the Wait issues in Selenium. With this feature, Katalon Studio will automatically pause until all front-end processes of a web page have been completed before proceeding to the next steps. This ensures uniform execution outcomes and helps QA engineers save considerable time by avoiding unnecessary investigations into false alarms.
  • Image-based Recognition: This is considered a breakthrough feature in test automation and is under development. In its initial release, end-users will be able to engage with application elements using keywords, eliminating the need to write scripts for element location.
  • Dual-editor Interface: Katalon Studio offers manual and scripting options allowing automation beginners to commence automation immediately, while also providing automation experts with the capability to create advanced test scripts.


Selenium is an open-source framework for a range of tools and libraries that aims at supporting browser automation. It also provides a playback tool for authoring functional tests across most modern web browsers, without the need to learn a test scripting language.

Benefits of Using Selenium:

  • The Selenium test script can be written in different programming languages like Java, C#, Python, Ruby, PHP, Perl, and JavaScript.
  • Selenium offers record and playback features with its browser add-on called Selenium IDE
  • The powerful Selenium WebDriver helps you create the most complex and advanced automation scripts.
