Automation testing is one of the most important practices in the field of quality software delivery. We cannot agree more with the fact that in today’s agile development methodologies, every software development process requires automation testing at some point in the development phase to accelerate the effort of regression testing. An automation testing tool can help testers as well as the whole team to concentrate on their respective tasks that cannot be handled by the automation tool. But, the hardest part about automation testing is selecting an automation tool. In fact, the most common question asked by testers is, “How to select the best automation testing tool?”

In this article, we will discuss in detail how to make your selection when it comes to choosing an automation testing tool. But before moving on, let’s highlight the importance of automation testing tools.
Importance of Selecting Best Automation Testing Tool
If you want to have a successful automation testing for your project, then identifying the right tool for automation is crucial. Choosing the right tool for your project automation testing is one of the best ways to get desired results for your project. Let’s take an example of web app development to understand the importance of automation testing tools better.
Imagine you’re developing a website for your business. Now, in the beginning, you don’t need any automation testing if you’re starting a business on a low level. All of the testing can be done with manual methods. But, when your business starts growing and starts getting recognition from a broad audience, then you might need to automate some of the processes like cross-browser testing of your web app to ensure it provides a similar experience to all the users.
Moreover, if there is a need for regression tests, then also you need to execute automation testing. That’s why selecting an automation tool that can provide all these functionalities is essential.
Types of Automation Testing Tools
There are generally three types of automation testing tools to choose from. Below is a short description of every type:
1. Open-Source Tools
Open-source tools are basically free platforms that allow you to access and use source code, which can also be modified from its original design. There is no cost or charge involved in using open-source tools.
Also, open-source tools can be used for any phase of the testing process like test case management, bug tracking, debugging, etc. However, open-source automation tools have fewer features as compared to commercial testing tools.
2. Commercial Automation Testing Tools
Commercial testing tools are specially designed and produced for commercial purposes. For example, large enterprises like Amazon, IBM, and Samsung use commercial automation testing tools as they are available with extended features and support from the technical teams. Some of the best commercial automation testing tools include LambdaTest, CrossBrowserTesting, and Browserstack.
3. Integrating Multiple Libraries to Build Custom Framework
For niche testing projects, there are particular characteristics for the testing environment and testing process, which cannot be fulfilled by open-source or commercial automation testing tools. Thus, the testing lead needs to consider the development of a custom tool. These kinds of tools are rarely used by a few organizations, as they need to be explicitly developed.
Factors to Consider when Choosing an Automation Testing Tool
Choosing the right automation testing setup is dependent on multiple factors. Each and every testing setup is either unique at the get-go or evolves into something totally novel as the project grows. To choose the right setup that will scale up as your project scales is equally important as choosing the right tech stack for developing your application. Here are a few factors that will influence your decision
Whether the tool will support your test activities or not, and if it is available in the market or not.
Which automation testing tool will best fit your project requirements and your budget.
If your team has the required skills to use the tool or not, and if not, then who will use the testing tool once you purchase it.
Is the automation tool accurate for the project environment and technology that you are using?
Is there a free trial version of the tool so that you can analyze its performance before purchasing it?
What are both cost and development efforts involved in scaling up the testing platform as your project grows?
How difficult it would be to maintain and manage older tests to work with new updates in the project?
Do you want the automation tool for a specific project or all of your testing needs?
Although there are many factors included in selecting an automation tool, we believe these are the essential factors that you need to consider before looking for automation testing tools. Let’s dive deeper into the concept of selecting the best automation testing tool.
Selection Criteria for Choosing the Best Automation Tool
Whatever your project requirements are for the automation testing tool, there is always a simple yet effective approach to choose the best automation testing tool for your project.
1. Analyze Your Project Requirements Comprehensively
It’s crucial to maintain the quality of your project by delivering a bug-free product for the success of your project. And automation testing is the best approach to improve the quality of any project, as well as to increase the depth and scope of the tests. But, before implementing automation testing, have a clear understanding of your project requirements, such as:
What is the project type? Is it a web/desktop/mobile application or any other project?
What is the scope of the project after its release?
Analyzing the strength of your testing team on code language before starting the process
Generally, there are no such automation tools that are entirely good or bad, but if you are expecting a good ROI from the tool, then it solely relies on your project needs like what you actually need to automate and how many test cases require automation testing.
For most projects, it is considered that both manual and automation testing are essential for the testing of web, mobile, and desktop applications. Thus, they choose a tool that can integrate seamlessly with the project planning and test management tools, as well as quick to learn and easy to use.
2. Compare Your Existing Automation Tool as A Benchmark
If you are using an open-source automation tool like Selenium test automation, then consider it as a benchmark to evaluate and identify the best automation testing tool for your project. For that, you need to know the pros and cons of Selenium automation tools.
Selenium is the first choice of testers who are comfortable with coding techniques and testing their websites via the user interface. Also, the maintenance of Selenium Suite is not easy, especially for a tester who often oversee the manual and automation testing. Another challenge that you might face with Selenium is the browser compatibility testing of web apps because automating cross-browser testing across multiple combinations of browsers, OS, and devices is not possible.
Therefore, it is vital to choose your current testing tool as a benchmark and compare it with the tools that you have decided to purchase for automation testing.
3. Verify the Critical Criteria Appropriate for A Project
Before finalizing the best automation tool for your project, you should consider the following key points:
The test execution must be simple for any project member so that they can run tests efficiently when required. Also, it should be easy for non-technical users who have very little technical knowledge.
The test reports generated by the tool must be intuitive and simple for the management team so that they can understand the testing process.
The automation testing tool must support all three platforms, including web, desktop, and mobile applications.
The development and maintenance of test scripts must reduce human effort and time resource management.
The automation tool must support a wide variety of browsers and platforms when it comes to cross-browser testing of web applications.
Support for keyword-driven testing because it acts as an extension to the data-driven testing framework.
There are some scenarios in which testers need to write the code. Thus, the automation tool must support the required languages so that testers can easily write the code.
Technical support and assistance are the top priority when it comes to selecting an automation testing tool, so make sure you get continuous technical support for your tool.
Additional features like screenshot testing, visual appearance testing, real-time testing, etc. must be included with the automation tool.
Compare these critical factors for different automation tools, and then select the best ones from them.
4. Consider Your Budget Before Purchasing a Tool
After comparing different automation tools on the above criteria, the last thing you want to check is your budget. Budget is one of the most critical concerns when it comes to purchasing an automation testing tool because, based on your requirements, if the tool is too costly, then you should avoid buying it.
However, if you and your organization have finalized to purchase the tool, then it recommended to download and use the trial version of the tool to analyze its performance and whether it’s worth investing that much money into it or not.
After using the trial version, if you find any issues with the tool, then don’t spend much time on it and look for another automation testing tool. Purchase a tool only when you’re sure about its functionalities and performance.
