Best UI Automation Tools

When I design, I work very hard to make the interface experience feel like there’s a human on the other end, not a computer. – Aarron Walter (Author of Designing for Emotion)

The given statement made by Aarron Walter points at a significant idea pertaining to the need to perfect the design of an application. It is important to ensure that the design is user friendly and is able to be seamlessly operated upon by the user.

In order to ensure this, it is important to test the UI (User Interface) which can then be undertaken in a manual or an automated fashion. Given the limitations of Manual Testing, there has been an increasing tilt towards the demand for Test Automation. The latter is conducted with the help of certain Web UI Test Tools which are chosen on the basis of specific criteria.

In this blog, we will look at five of the best Automated UI Test Automation Tools. We will begin with understanding the concept of UI Testing, the criteria to be followed for selecting a specific UI Automation Tool as well as look at some of the most popular UI Testing Tools.

What is UI and UI Testing?

UI or User Interface refers to that part of the application or website which users interact with. However, UI is not a singular entity. There can be different forms of UI and the most common ones are: Command-line Interface (interaction is facilitated through feeding commands into the terminal) and Graphical-user Interface (refers to interaction with graphical components of the application or website).

The first impression (which is usually the last as well) that the user acquires of the website is generally determined by the quality of the user interface. Thus, UI is extremely significant in terms of determining the future viability of a software application.  Consequently, UI Testing has emerged as a crucial concern among developers and testers alike, as they seek to meet the ever increasing user standards.

UI Testing can be understood as a mechanism for testing the different interface aspects and components of a software, in order to ensure their desired functionalities and user-friendliness.

In other words, UI Testing aims at two things: testing the receptivity of the software application towards the actions of the user as well as, testing the functionality of the visual elements (images, links, buttons and so on).

Furthermore, UI Testing is extremely crucial in terms of testing visual design, compliance, usability and performance as well. It ensures the workability of the application. Alongside, it also seeks to make sure that the interface is as user-friendly as possible, in terms of clarity and intuitiveness. Thus, UI testing is not simply a means to evaluate the functionality of a software application, but is also a means to ensure that users are able to derive the most from a product with the least effort.

What are UI Test Tools?

Automated UI Testing Tools are innovative software tools which help in executing automated tests on applications and software which requires the testing of the user interface. The Web UI Test Tools makes use of test cases in order to ensure that the software application performs its designated functions. It is important to remember that a UI Automation Tool, not only provides for automation of test scenarios, but also provides for meaningful analytics which could overcome test challenges.

Choosing the right UI Test Tools is indispensable for efficient execution of the test strategy as well as for overcoming the challenges of testing in general. Then again, there is much of a debate over the choice of code-based or codeless UI Testing Tools.

However, it is important to remember that there cannot be a universal suggestion and while codeless Automated UI Testing Tools do help in reducing the cost of creating test cases, they might not be favorable in all situations.

In the next section, we will examine some of the considerations you should keep in mind when choosing a particular UI Automation Tool.

Criteria for Selecting a Specific UI Automation Tool

The market is filled with numerous Web UI Test Tools. Selecting a specific UI Automation Tool solely based on its popularity can prove counterproductive in the long run.

In this section, we will look at some of the factors one can consider while thinking about UI Test Tools.

The Object of Automation

Choosing a UI Automation Tool will largely depend on the nature of the product that needs to be automated. It’s important to understand what your product can do and how it can be automated. Before considering different UI Testing Tools, you should try to understand the product’s type in terms of its domain, internal structure, and technologies employed by the product.

The Importance of Team

The performance of Automation Testing is not the outcome of the efforts of a single individual. It is a collaborative effort of the entire team and it would only be wise enough to choose a UI Automation Tool which works for all the individuals of the team. This can be thought of in terms of choosing UI Test Tools which uses programming languages that the team is comfortable working with or taking into account the experience of the team at automation, along with the nature of their organization.

The Context of the Test

While trying to choose a specific UI Test Automation Tool, it is important to remember that it would be rather naive to suggest that there is a specific tool that would deliver the best results in all situations. It is important to consider the context of the project or the test. Some tools will fit appropriately in certain contexts.

Project Details

When considering the different UI Testing Tools, it is important to be clear of the nitty-gritty of the project. This will involve developing a concrete idea of the project budget, project deadlines, and project planning.

Top 5 Automated UI Testing Tools



As one of the leading UI Testing Tools, Selenium was originally developed by Jason Huggins in 2004. It is an Open Source UI Automation Tool used for conducting Selenium Automation Testing. It is generally used for Regression Testing as it offers record and playback facility. Recorded scripts can be exported in other languages, it can be integrated with TestNG and JUnit, multiple tests can be executed as well as comments can be inserted in the middle of the script.


  1. This Testing Tool can be executed on multiple Operating Systems and Browsers. It runs on Linux, Windows and OS X; and is compatible with Chrome, Headless, Internet Explorer as well as Firefox
  2. IDE and WebDriver components of Selenium, act as the basic framework for several other Automation Testing Tools including Watir, Robot Framework and Katalon
  3. Tests can be written in multiple languages including Java, Python, C#, Groovy, Perl, PHP and Ruby
  4. It supports parallel execution of test cases as well as provides for easy maintenance of code
