Although manual testing is still a powerful tool in software quality assurance, as we’ve established once again in our recent longread on manual vs. automated testing, more and more companies rely on testing automation for all-encompassing coverage and cost-effective QA. And automated testing tools are the key component of a well-designed testing process.

By one estimate, 26% of organizations struggle with finding the right tool for a test automation project. It can happen for a myriad of reasons, from having trouble matching the QA team to the tool to being determined to work with a free solution even though there aren’t any that fully meet the needs of the project. This is why the process of selecting the toolset for an automation QA project needs to be treated with care.

To help you make the right decision when it comes to speeding up your automation project and making it more efficient, we have prepared a detailed guide on what to look for in a good testing automation tool and which tools are worth considering in 2023.

#What is an automation testing tool and what does it do?

A test automation tool is an application or software product designed to verify functional and non-functional requirements via automated test scripts. An automation testing tool can perform a variety of tasks, from developing and running tests based on a specific schedule or whenever a code change takes place to generating in-depth reports for the team to review the results of testing.

The choice of an automation tool is an integral part of any automation testing strategy, helping create a roadmap for the project and giving the team something to rely on for effective and resource-saving testing. There are often situations that call for developing an automation framework from scratch (and some AQAs prefer it that way due to the flexibility it provides), but most automation testing tasks can be completed with the use of ready-made tools. 

#Types of automated testing tools

Knowing the different types and characteristics of test automation tools helps you save time on finding the ideal solution, since you will quickly know where to look. There are several approaches to categorizing all the tools for automation available today. The two most common ones are by purpose and by availability.

#By purpose

Most automation tools are created to serve a specific purpose, such as supporting a particular type of testing. These are the most popular tools for automating different types of software testing.

**UI testing tools**
Since most software products are intended to be used by consumers, ensuring a great user experience is vital for an emerging solution. Automating UI testing with the help of the right tools helps the stakeholders gain confidence in the appealing user experience and future success of the product.

**Load and performance testing tools**
Users have come to expect spotless performance at all times, and Load and performance testing are the go-to way to test these aspects of the solution. Load and performance automated testing tools allow testing software with a large number of scenarios in a limited time and provide outcome metrics and reports that help analyze the results.

**Functional testing tools**
Similarly to UI test automation tools, functional testing tools help the team make sure that the application is working exactly as it’s intended. However, functional testing tools go deeper to verify the correct operation of a software product and doesn’t just focus on the user interface part of the application.

**Regression testing tools**
Automating regression testing is one of the most common reasons for organizations to adopt automation in the first place. There is simply no reason to have multiple manual QA engineers working on the same chunk of regression testing when one or two AQAs with the right tools can automate this process and achieve more consistent results.

**Mobile testing tools**
There are some testing tools, such as Ranorex Studio and Appium, that support both web and mobile solutions. However, if you are primarily working in the mobile segment of software, it makes sense to choose an automation tool designed specifically for the mobile environment. That way, you can expect the most reliable results.

**By availability**
The availability of an automation testing tool is an important factor to take into consideration when choosing among several options. These are the types of automation tools based on their availability and distribution principles.

**Commercial**
Commercial test automation solutions are developed by software companies for profit, which is why they are typically only available on a paid basis. As a customer, you can sometimes take advantage of a free trial version that is only available for a limited period of time or comes with limited functionality. To use the solution in full, you will need to purchase a license. It can be a lifetime license or a monthly/quarterly/yearly subscription.

**Open-source**
Open-source automation testing tools are developed by the community and for the community, which is why they are distributed for free and without any conditions. Open-source automation software is a popular choice for organizations that don’t have a large budget to spend on setting up the automation process but have the resources to learn and integrate the tool into CI/CD to make it fully match the needs of the project.

**Custom tool**
For some projects, the readily available tools may never be able to do the trick. This typically happens when the automation process, environment, or scope of testing are too different from most standard procedures in the industry. The sensible solution in these situations is to develop custom automation tools based on the project requirements. Needless to say, this solution requires an expert-level understanding of coding in addition to the already high automation skills of the team.

#How to choose the right automation tool for a project

When choosing the tool or toolset for automation software testing on a particular project, the only working strategy is to do it based upon the specifics of the project itself, and not the most popular tools available on the market or a set of tools that worked well on a previous project.

The decision to select a tool for test automation is something that should ideally be made jointly by the stakeholders of the project. This can include the client’s representatives, the project manager, and the Automation QA lead. However, this only works when every participant has the technical and business knowledge needed to make an informed decision. In other cases, the project can run into a few difficulties:

  - When the client requires the use of a specific tool using only business considerations, the rest of the team may find it challenging to incorporate the tool into the workflow;
  - When the AQA engineer picks tools based purely on personal preferences, there is a possibility of the project becoming difficult to develop and maintain in case the engineer quits and leaves behind a complicated tool stack.

> “There is sometimes a conflict of interest between the Automation QA and the stakeholders on the project: the QA wants to try as many different tools as possible without necessarily following the company’s best interest, whereas the company prefers standard, unified, easily maintainable solutions. This is why it’s a good idea to have a person with not just technical, but also business expertise overseeing the choice of tools on a project.”

> Taras Oleksyn, Head of Automation QA, TestFort

#Factors to consider

As we’ve mentioned earlier in this article, the most sensible approach to choosing a tool for automating a QA project is to take into account the individual parameters of the project. Here are the key factors to consider when making tool-related decisions on an automation QA project.

1. Objectives of the project
Automation testing projects are not created equal. The nature and purpose of the project can be very different even within the same organization. The two vital questions to answer at this stage are: 

 - What exactly are you trying to automate?
 - Which results do you want to achieve in the end?

The answers to these questions will contribute to the selection process. For example, if your goal is to automate parts of UI testing, the choice of tools will be different from a project where the goal is to ensure comprehensive load and performance test coverage.

2. Technical capabilities of the testing tool
Different automation testing tools are created with different sets of features and possible limitations. Some of the most vital technical capabilities to consider here include the supported programming languages, the compatibility with the project ecosystem, such as operating system and hardware, and the types of testing you can carry out with this specific tool.

3. Project budget
There are free automation testing tools and paid automation testing tools. With paid tools, the cost can range from a few dozen to thousands of dollars, and the payment type can be different as well: vendors can charge a lump sum for a license once or provide their software on a paid subscription basis. These are essential factors for making the right choice, especially when the project budget is limited.

> “It’s very important to maintain the right balance between aiming to save money and working towards a successful project outcome. There have been cases in my practice where the company was determined to work only with free tools to save money but then ended up spending even more money and time when the tool proved to be the wrong choice for that specific project”

> Maxim Khymii, Automation QA Lead, TestFort

4. Ease of use and learning curve
Some automated testing tools are incredibly easy to master even for non-technical users, while others require deep technical expertise just for the setup stage. It’s very important to measure the skill level of your team against the selected tool to make sure they make a good match. Moreover, the project lead needs to allocate time for the team to familiarize themselves with the suggested tools.

5. Ability to integrate with other systems
Modern automated testing tools rarely exist completely autonomously from the rest of the QA project, so integration capabilities are another critical feature to consider here. This can include your bug tracking software, project management tools, the CI/CD process, and other big-picture parameters of an automation environment.

6. Need for coding skills
Although some are convinced that modern AQA engineers no longer need to have coding skills in order to be good at automation, others, including the AQA leads at our company, believe that at least some knowledge of coding is required for an efficient project. Whether or not your team members know their way around software code is going to impact your choice of tools.

7. Reporting
The work of an automation QA tool does not stop when the last test in the suite is executed — it’s also vital to analyze the obtained results and evaluate their short-term and long-term impact on the quality of the product. One of the best ways to do it is through reports. The tool you use needs to issue detailed, accurate reports, and it’s even better if the report is customizable.

8. Community, support & maintenance
When searching for the perfect test automation tool, look for a solution that is actively maintained by its vendor and provides customer support and troubleshooting. Similarly, a solid community around a software solution can help the team adopt a tool faster and avoid many of the roadblocks that can take place with a more niche tool.

#How to know if your automation tool works

With so many popular and versatile automation tools out there, making the right choice is not always easy, especially for teams without a lot of hands-on experience with automation. At the same time, it’s worth noting that it’s vital to choose the right tool from the get-go, as any major changes to the process once the project is already launched will result in losing valuable time and money spent on working with the wrong tool.

The set of metrics for measuring the efficiency of the selected tool or set of tools will always depend on the project itself and the goals set by the team in the first place. For example, when the main goal was to automate as much of the current project as possible, it makes sense to evaluate the overall number of cases automated in a given time period. Whereas for teams focused on optimizing the resources within the project, the key metric would be Equivalent Manual Test Effort — the number of working hours saved by the introduction of testing automation.

The exact set of metrics for measuring the effectiveness of the automation tool should be designed and implemented by an AQA Lead or a person with a similarly rich experience in automation. However, when the results prove to be disappointing, the tool is not always the culprit.

> “In my experience, most cases of an automation testing tool not living up to everyone’s expectations are linked to the human factor, not some technical issues. It may be a case of a bad match between the team and the tool, or a case of some team member underperforming or not fully understanding the task. The automation tool itself is rarely to blame.”

> Taras Oleksyn, Head of Automation QA, TestFort

This quote once again proves that it’s vital to make sure that the tool you consider using matches the skill set of your team and vice versa.

#Where does the automation testing tool market stand in 2023?

The test automation tool market is constantly changing: in addition to a few biggest ubiquitous players, there are plenty of notable newcomers. Moreover, the automation testing industry as a whole is transforming right before our eyes. These are the biggest trends and movements we will witness among automation tools in 2023:

 - Increased use of AI and ML. Artificial Intelligence and Machine Learning are two of the most discussed technologies of 2023, so naturally, they are also featured more and more in test automation solutions.
 - Growth of cloud services. In order to ensure the spotless performance of an application, it’s essential to test it on all kinds of devices, browsers, and operating systems. However, companies cannot always afford their own device farms with dozens of devices for testing. Automation testing outsourcing can be a great way to resolve this issue, but there is also a growing number of tools providing cloud platforms for testing.
 - Shift towards simplicity and easy adoption. A common trend among multiple established and up-and-coming tools is the swift move from complicated techniques that require deep knowledge of coding to low-code and no-code tools based primarily on the record and playback functionality.

> “The software testing industry is definitely witnessing a move towards low-code and no-code automation tools. I’ve found that in many cases, no-code tools can be as effective as tools that require the knowledge of code. However, I still believe that coding knowledge is invaluable for an automation testing engineer: with it, they can make the tests even more supportable and flexible by getting rid of the brittle code that has no impact on the testing results.”

> Maxim Khymii, Automation QA Lead, TestFort

#Final thoughts

The choice of an automation testing tool is not the only one the team will make when launching an AQA project, but it’s definitely among the most important ones. A wrongly selected tool will prevent the team from reaching their objectives, cause them to lose time and money, and lower the efficiency of the whole project. This is why, if you’re involved in the selection process in any role, it’s best to both know the principles of choosing a suitable automation tool and be familiar with the most popular and acclaimed tools in the industry.
