How to Choose the Best Automated Functional Testing Tool in 2023?

In a nutshell: In the DevOps era, test automation is essential for accelerating the release of high-performing, bug-free software—and, of course, automation would be impossible without the right automated functional testing tools. This guide covers: Defining test requirements for your project, comparing the key features of each testing tool, and making an informed decision based on your project.

In the DevOps era, test automation is essential for accelerating the release of high-performing, bug-free software; and, of course, automation would be impossible without the right automated functionaltesting tools. 

However, with so many testing tools available on the market, it’s not easy to choose the one that best suits your needs.

In this article, we'll explore the key factors to consider when choosing the best automated functional testing tool in 2023.

1. Define the test requirements for your project

The key questions you need to answer first are:

• What are you trying to automate?
• What results would you like to achieve?
• What is your existing infrastructure? (development environment, programming language, testing framework)

2. Look for tools on the market that meet your needs

Once you have defined your testing requirements, the next step is to research the various automated functional testing tools available on the market and analyze the pros and cons of each. 

Researching the various tools will help you understand their features, capabilities, and limitations.

Some of the popular tools in 2023 include: 

• Selenium
• Playwright
• Cypress
• Appium
• TestComplete
• Katalon
• Mr Suricate
• Ranorex
• Leapwork
• Tricentis
• LambdaTest
  

Compare the key features of each testing tool

Every automated functional testing tool has its own advantages and disadvantages.

For example, Selenium is an extremely flexible open-source testing tool, but it is very technical to understand and use. 

On the other hand, the Katalon solution, built on the Selenium and Appium frameworks, is considerably easier to use, but the tool has limitations in terms of its scripting capabilities and device support. 

The main factors to consider:

Reporting Capabilities

The success of an automated functional testing tool depends on your ability to identify what needs to be fixed as quickly as possible. 

Therefore, it is important to review all the features of the reports supported by a tool. 

The tool you use should generate detailed and accurate reports, and it's even better if the reports are customizable.

Ease of use

When choosing an automated testing tool in 2023, the importance of ease of use depends on your team's skill level. 

But even if your team consists of technical professionals who know how to code, the tool must be intuitive and easy to navigate to make it user-friendly. 

With or without code (“no code”)?

Why choose a no-code automated testing tool? 

Save time: No-codeautomation tests take less time. The team can devote more time to other high-value tasks. 

Cost-effectiveness: By reducing the time and effort required to perform tests, costs are significantly reduced. 

Avoiding Human Error: A no-code testing tool is less prone to errors than tests manually scripted by a developer. 

Suitable for non-technical users: Low-code solutions for non-technical users offer companies an alternative to hiring expensive staff and dealing with long lead times. 

Versatility: No-code testing tools are easier to modify and adapt to different test cases, making them more versatile. 

Flexibility

Even if a tool is suitable for a specific project today, it must be flexible enough to support multiple testing frameworks, operating systems, and devices. 

This will ensure that the tool can be used for various types of tests and can adapt to changing needs.

Technical Support, Community, and Maintenance Requirements

Support and maintenance are critical factors to consider when choosing an automated functional testing tool. 

The supplier must provide adequate support and maintenance services, including bug fixes and updates.

Clear and comprehensive documentation should also be available to you so that you can be as independent as possible.  

Similarly, a strong community centered around an automated testing solution can help the team adopt a tool more quickly and avoid many obstacles.

Price

The price depends on the type of tool. There are three types of automation tools: 

1. Sales 

Commercial test automation solutions are developed by for-profit software companies. 

As a result, they are generally available only for a fee. 

As a customer, you may sometimes be able to take advantage of a free trial version that is available only for a limited time or has limited features, but to use the solution in its entirety, you must purchase a license. 

This can be a lifetime license or a monthly, quarterly, or annual subscription.

*One advantage of commercial automated testing solutions is that they have a sales team that can explain how the solution will work for your specific situation during a demo. 

2. Open-source

Open-source test automation tools are developed by the community and for the community, and are distributed free of charge with no strings attached. 

This type of automation tool is a popular choice for organizations that don’t have a large budget to devote to implementing the automation process but do have the technical staff (who are generally expensive...) to learn and integrate the tool into their CI/CD pipeline so that it fully meets the project’s needs.

3. Custom Tool

For some projects, the available tools may never be sufficient. 

This usually happens when the automation process, the testing environment, or the scope of the tests differ too much from most industry-standard procedures. 

The best approach in these situations is to develop custom automation tools tailored to the project's requirements. 

Needless to say, this solution requires an expert-level understanding of coding in addition to the team’s already advanced automation skills.

3. Make an informed decision based on your project

When choosing an automation tool, the best strategy is to base your decision on the specific requirements of the project.

The decision to select a test automation tool is one that should ideally be made jointly by the project stakeholders. This may include client representatives, the project manager, and the QA manager. 

To avoid potential difficulties, each participant must have the technical and business knowledge necessary to make an informed decision.

FAQ

What criteria should you use when choosing a functional testing tool?

Ease of use, support for multiple environments, scenario maintenance, integration with CI/CD, quality of support, and actual long-term cost.

Should we use a no-code tool or a developer-oriented one?

It depends on the teams. No-code platforms make testing accessible to business users, while code-based tools offer more control but require technical skills.

How can you avoid choosing the wrong tool?

By testing it against its actual critical workloads during a trial, and by evaluating the maintenance costs—not just the license price.

Is the cost limited to the subscription fee?

No. The true cost includes the time spent creating and, above all, maintaining the tests. A tool that reduces maintenance is often more cost-effective.

What Mr Suricate stance?

A no-code solution that reduces maintenance and combines testing and monitoring, suitable for both business teams and large enterprises.
