Automation Testing Tools

Automation Testing Tools

In our last blog, we talked at length about automation testing and how it contributes largely to the software development. However, one of the biggest challenges in automation testing is choosing the right automation tool. In this blog we will discuss in detail about various types of automation tools available in the market. We will discuss how these tools can be classified and how you should choose the best tool for you. At the end, we will also present a list of most commonly used and useful test-automation available in the market.

Different Types of Test Automation Tools

Test automation tools can be classified into many categories as discussed below:

Codeless vs. code-based vs. hybrid tools

Few test automation tools require coding skills, and few don’t. There are also hybrid tools that bring together the best of both worlds. They allow testers and other professionals with no coding skills to create test cases with the use of some visual tool and then can enhance those test cases with the use of a language such as JavaScript.

Commercial vs. open source

When it comes to pricing schemes and licenses there are variety of test automation tools. Few tools are completely free/open source and others are closed source but offer free versions or at least a free trial. Additionally, it’s been increasingly common for test automation tools to be offered in a SaaS model, in which the client pays a monthly or an annual subscription.

Desktop vs web vs mobile

Test automation tools also differ when it comes to the different types of software they support. You can have tools that target desktop applications for example windows-based tools. On the other hand, few tools are specifically designed to target handheld devices. Nowadays, it’s more common to immediately think of web and mobile apps when testing tools come up and choose a tool that fits the requirement better.

Production vs. non-production testing

Nowadays it is common and beneficial to perform some kinds of testing on the application after it is in production. Techniques such as synthetic and non-synthetic monitoring, chaos engineering, A/B testing, canary releases, load testing and performance testing in production are a few that come to mind.

Select the Right Automation Testing Tool

Selecting the right tool is essential for test automation. There are a lot of automation testing tools on the market, and it is important to choose the automated testing tool that best suits your overall requirements.

You can consider the following key points when selecting an automated testing tool:

  • Support of platforms and technology– Are you testing .Net, C# or WPF applications and on what operating systems? Are you going to test web applications? Do you need support for mobile application testing? Do you work with Android or iOS, or do you work with both operating systems?
  •  Feature-rich but also easy to create automated tests– Check the supported features such as record-and-playback test creation, manual creation of automated tests, implementing checkpoints to verify values, databases, or key functionality of your application?
  • Create automated tests that are reusable, maintainable, and resistant to changes in the application’s UI.
  • Integrate with your existing ecosystem- Does your tool integrate with your CI/CD pipeline such as Jenkins or Azure DevOps? Or your test management framework such as Zephyr?
  • Ability to test enterprise applications Does your tool offer out-of-the box support to test packaged applications such as SAP, Oracle, Salesforce, and Workday?
