17 Types of Usability Testing: A Comprehensive Guide

Given the current market, where user satisfaction becomes a deal breaker for many companies, the necessity of various QA usability testing routines is as clear as ever. That’s why, in this guide, we share some of the best usability testing practices and how to use them under the specific circumstances.

What Is Usability Testing in QA?

Usability testing is one of the most crucial components of the quality assurance process. However, while evaluation of the user’s interaction with the system is one of the primary goals of this testing type, usability testing is not only about technical bottlenecks or bugs. The essence of usability testing goes far beyond regular technical checks – it lies in the need to provide the best UX for your customers.

General Concepts of Usability Testing

Usability testing for QA assesses the user’s interaction with your particular product. It focuses on verifying task completion, navigation, feature perception, and overall ease of use. It’s also necessary to restate that even though usability testing might appear similar to functional or performance testing, it’s no more than an illusion.

But, the good news is that it’s pretty easy to distinguish them, since usability testing ensures that the product is convenient, performance and functional testing analyze the speed and performance of the system. It’s also worth specifying that usability is an early bird in the QA routine, since it is usually performed at the early stages of the SDLC. Yet, it doesn’t negate that you can do this testing at the end of the cycle to polish the result to perfection.

Types of Usability Testing

In this section, we will take a closer look at different usability testing methods and how they can improve your product’s performance. Each of the testing types provided in the sections below represents a unique testing piece that focuses on conducting separate program elements. So, let’s not wait another second and find out how each of them works and which strengths and weaknesses various usability testing types possess.

Moderated Usability Testing

This method involves engaging a special person, known as a facilitator. This specialist guides users through the program’s interface while observing and asking clarifying questions. Usually, moderated usability testing is included in scenarios when the fine-tooth feedback is essential. As for the execution, moderated testing is performed online or in person to facilitate the collection of feedback. It also has advantages, such as real-time interaction and the ability to ask clarifying questions. Yet, some QA engineers consider it time-consuming and less scalable.

Unmoderated Usability Testing

Unlike the previous type, unmoderated usability testing focuses on users who perform the required tasks without a facilitator present. That’s what makes the mentioned type of usability testing a perfect match for scenarios when you need rapid results at a lower rate.

Regularly presented via tools like Playbook UX or Maze, this test is known for its quick deployment and suitability for larger audiences. Still, your team needs to be prepared for drawbacks like limited insights and no real-time clarification.

Remote Usability Testing

Next on our checklist is the testing format that can be performed regardless of the location or circumstances. The remote routine will suit you best in cases where you need to estimate user groups from different places. In the meantime, remote usability testing tools like Lookback will grant you the opportunity to collect feedback and control the process. Remote testing can offer you the convenience and flexibility, but it can disappoint you in factors like a lack of environmental control.

In-Person Usability Testing

This software usability testing method obtained its name because of the need to conduct research face-to-face. Due to this feature, it becomes a perfect option for the testing of mobile products or inventions where the tester’s presence is required. It is usually held in offices, labs, or other locations that offer advantages like immediate feedback or allow you to observe subtle details. Among the disadvantages are frequently mentioned time consumption and increased difficulty.

Exploratory (Generative) Testing

In comparison to the previous types, exploratory usability testing aims to discover ideas and obtain early feedback. That’s what makes this form a perfect match for the start of software development and exploration of possible hypotheses.

The whole concept revolves around free exploration of the specific features, with little or no instructions. Such an interesting approach helps uncover hidden bottlenecks and reveal unexpected behaviors, but in certain situations, it lacks directness.

Comparative Testing

Comparative type helps QA engineers evaluate multiple hypotheses or concepts at the same time. This approach is regularly used when developers have several suitable features or ideas, so they need to run tests to check them in real-world conditions. Usually, it is carried out as A/B tests or multivariate routines in the form of structured tasks. This approach offers you a unique opportunity to make a data-based decision based on direct comparison. Nevertheless, this testing routine is often limited in scope.

Task-Based Testing

It focuses on users completing specific tasks, which allows the team to evaluate a product’s performance. For instance, task-based testing can help developers check time completion, ease of navigation on the website, or even the effectiveness of particular elements.

In task-based testing, users are instructed to perform specific actions based on instructions provided beforehand. It allows the QA team to receive simple and measurable results, but on the other hand, it can also miss a larger scope of usability issues.

Guerrilla Testing

Seems similar to in-person testing, but it includes the involvement of random users. Such a specific approach makes guerrilla testing a perfect addition to testing MVPs or early validations of the product’s elements. It includes gathering feedback from random people or accidental visitors. All those particularities make it perfect for early insights and low-budget startups. On the other hand, participants rarely meet the requirements of the target audiences, and the tests are not well-structured.

Hallway Testing

Like guerrilla testing, hallway testing is based on randomness and physical involvement. The only difference is that this testing scenario involves internal specialists, such as coworkers or non-technical staff. The whole test can be run in a few minutes, when you grab any colleagues who came along and ask them to evaluate specific features. From the advantages, there is the absence of any special equipment and convenience. As for the cons, unfortunately, the received feedback rarely covers the real customer’s pain.

Card Sorting

Before the testing stage, you gather a group of customers who will experience the product. Once finished, the card sorting method implies labeling the content in a way that feels logical to the customers. This approach is perfect for categorizing design solutions or structuring the information architecture. There can also be a pre-defined category, where you set the requirements from the beginning, or users can do it by themselves.

As a result, it’s a great way to improve navigation and accelerate customers’ engagement. On the other hand, we are receiving subjective results and a lot of data to analyze.

Tree Testing

A reverse type of the card sorting method in which the QA team evaluates how well customers can find different elements in a hierarchy. It’s frequently used in situations when validation of the program’s structure is required. Specifically, during the tree testing, you need to check whether users can freely navigate the app using a text-based hierarchy only. From the benefits, it grants you the ability to identify structural issues early, yet it doesn’t assist in checking visual components.

Eye Tracking/Heatmaps

This type of usability evaluation provides you with special heatmaps that show the areas of focus for users’ attention. Such a unique feature makes heatmaps a perfect option for checking complex UI screens or advertisements. During the process, special eye-tracking platforms record gaze patterns and form special zones of the user’s attention. Heatmaps and eye tracking unlock huge insights into interaction flows, but in the meantime, they require a thorough analysis to break down the results.

First Click Testing

At first glance, it may appear simple, but this test hides much more. By presenting user scenarios and asking them to perform regular clicks, we can reveal the clarity of navigation levels and the intuitiveness of the design. As a result, we receive informative feedback and a chance to determine confusing elements. However, those test routines won’t allow you to assess the entire journey of your product.

Five-Second Test

Five-second tests allow you to evaluate a first impression by showcasing a particular app part for a limited period. As a result, it greatly assists in gauging clarity and keeps focus on the effectiveness of UI solutions. During the test, you allow the customers to briefly view the content and then ask them to perform actions or answer questions. This test scenario is perfect for visual hierarchy, but doesn’t evaluate anything beyond the initial reaction.

Accessibility Usability Testing

This testing method allows you to ensure that your product is suitable for users with disabilities. It also helps you meet the WCAG requirements and make special, inclusive content. When it comes to test reproduction, it involves different assistive technologies and real users. In the end, you received a polished product ready for use by customers with special needs, but its implementation requires specialized tools and experience.

Mobile Usability Testing

Evaluation of mobile application usability includes components similar to previously discussed methods. The only difference is that it focuses strictly on the mobile products. The test usually includes device-specific behaviours, checks of swipes and taps based on the OS for which the product is developed. As for the advantages, it’s the complete and tailored feedback on mobile UX. Regarding the cons, we can mention the need for device variety.

Longitudinal Usability Testing

Performed over a fixed time, the longitudinal type allows you to track changes in UX over certain periods. In most cases, it is used in SaaS platforms or other products with quickly evolving features. As for the tests’ execution, it doesn’t contain anything special and typically focuses on user engagement with the product over fixed phases. It also allows you to track retention or changes in behavior. Yet, it is also considered time-intensive and challenging to maintain engagement.

How to Choose a Usability Test

Choosing a proper usability test is a complex task that should be based on various factors. Start by identifying the niche of your product, and then proceed to evaluating your budget, team’s experience, and available resources. For instance, projects at early stages may benefit more from exploratory testing, while MVP versions may benefit more from hallway tests or guerrilla routines.

Mistakes in Usability Testing

Even the correctly chosen usability testing may go in the wrong direction if you miss some of the general pitfalls. Below, we have gathered the main mistakes to avoid in usability tests:

• Wrong type of test. Using a test that doesn’t match your niche or product may lead you in the entirely wrong direction.

• Too few or similar users. Involvement of an insufficient number of users, or cohort groups that don’t cover the evaluated topic.

• Confusing tasks. Purely written tasks or guidelines are not something that can contribute to the successful test submission.

• Skipping edge cases. Disregarding the suspicious flows means you miss crucial real-world data.

Usability Testing Tools

A large number of testing tools are tailored to specific kinds of testing, from regular exploratory testing to complex heatmap sessions. For instance, tools like Maze offer you great options and instruments for unmoderated testing routines. Lookback is ideal for companies looking to perform moderated tests, and Hotjar is perfect for gathering behavior insights and heatmaps.

QA Insights: How Usability Testing Saved the Project

To confirm the absolute necessity of usability testing, let’s look into the history of Dropbox. During its early days, many Dropbox users struggled to understand shareable links. After running the tests that included feedback gathering, the team decided to simplify the flow and add clear visual cues. This simple step significantly improved user engagement with the product and boosted success rates to unprecedented levels.

Conclusion

Usability testing should not be considered a regular step in the QA routine. Treat it like a tool for polishing your product and turning every customer’s action into an unforgettable experience. Start early, change approaches frequently, and do not be afraid to experiment, since it’s the most critical thing for succeeding in digital development.
