User testing vs. usability testing: Removing the ‘guess’ from guesswork

Since the dawn of time, humanity has been asking the big questions: why are we here? What is the meaning of life? If we put the sign-up button in the corner, will users notice it or give up looking? 

We can at least answer that last question. Thanks to user testing and usability testing, much of what we had to guess or estimate when developing mobile apps and websites can now be rectified with concrete, empirical data — anything from the controls people use to which colors they want to see. 

If you’re unfamiliar with user and usability testing, you probably have more questions. This guide will answer them, starting with the big one: what’s the difference between user testing and usability testing? 

User testing vs. usability testing: what’s the difference? 

Say you’re implementing a new feature of your app. A user test determines whether or not the user likes or accepts the new feature. A usability test determines whether the new feature functions as it should.

Basically, user testing is about the user. It answers questions such as: what features do users want? How do they feel when performing tasks? Which image do they like best? We take what we learn from user tests and apply it to make better software, apps, and sites. 

Usability testing is less about user preferences and more about functionality and quality assurance, or QA. It answers whether or not a user can accomplish a task, and if they can’t, why not.

Usability tests require a working prototype and typically involve presenting the test user with a scenario to see if they can accomplish it. Mockup testing, for example, uses a mid- or high-fidelity prototype to assess usability before finalizing the visual design so designers can get it right the first time. 

As you can see, user testing and usability testing overlap quite a bit. Your prototype won’t score well on a user test without proper usability, and optimizing usability involves knowing user preferences for controls.

In fact, both are considered part of user experience (UX) testing, which aims to improve the all-around experience of using your product, website, app, software, etc. 

However, don’t confuse it with user acceptance testing. A user acceptance test is a type of usability test. It comes at the end, right before launch, to verify that everything on your acceptance criteria checklist is met — the final QA test. 

Why do we do user testing and usability testing? 

User testing is the best way to map out and optimize the user journey. To make your customers happy, you have to understand how they think. 

User tests are a way to fully understand the preferences, quirks, and motivations of your target users. They’re the perfect complement to your personas. The data from user testing can make those personas more effective. 

The reason for usability testing is more straightforward: to identify problematic areas that inhibit usage. As we’ll discuss below, it’s best to test frequently to address problems as early as possible. 

When should you do user testing and usability testing? 

Short answer: right away! Test prototypes at various stages of development to see if you’re on the right track. The sooner you identify usability problems, the easier they are to fix. If possible, test after each major iteration of your app or site. 

User tests can begin even before development. Doing market research through surveys or interviews can help inspire ideas for your team or reveal the best design elements. You might even discover new pain points in your user group that your product can address. 

You can begin design testing as early as the wireframing phase. Even with basic graphics, you’ll still get valuable data about information architecture, navigation, and usability preferences. 

You should also test after each major upgrade or code change. This type of testing is called regression testing.

What is the most effective way to user test your product? 

Usability tests are simple. Present your test-taker with a scenario — for example, have them sign in to their account — and take note of any obstacles, redundancies, or room for improvement. You can focus on specific tasks in specific areas, or present the user with an open-ended task and see how they handle it on their own. 

User tests are more varied, depending on your business goals and where you are in product development. Here’s a breakdown of common user testing methods and when you might use them.

Market research

Market research techniques such as interviews, surveys, social media listening, and competitive analysis can yield useful data for understanding your customers. This is instrumental early on. If you want to know the opinions, preferences, and pet peeves of your user group, all you have to do is ask. 

Focus groups

Focus groups bring together a handful of people from your user group. A moderator leads the conversation and keeps everyone on track. The data comes from what the people say. 

Focus groups are most effective early in the planning phase. Responses sometimes yield new and original ideas your team might not have come up with on its own. It’s a perfect way to cast a wide net and involve end users in the design process.

These days, you can conduct focus groups online, circumventing issues with scheduling, reserving a location, or health concerns.

Split testing

Also known as A/B testing, split testing shows users two or more different versions of the same visual (page, screen, icon, logo, etc.) to see which performs better. Ideally, each user only sees one version, so you’ll get their initial gut reactions every time. 

You can use split testing to optimize every aspect of your project: icons, web page background, color scheme, layout, product photo, call-to-action placement, text copy, CTA phrasing — even pricing. 

What’s the cheapest way to do user testing? 

Organizing user tests on your own gives you the most control, but demands the most effort. Tracking down relevant test-takers who fit the criteria of your user group is hard enough, not to mention other headaches like scheduling conflicts, reserving locations, writing test scripts, and hiring a moderator. 

Doing tests on your own may seem like the cheapest approach, but when all is said and done, outsourcing is less of a drain on your resources. 

Online user testing tools offer a range of pricing options, depending on the services you require. In general, they’re quite affordable, even for small businesses.

Expertise and time are the two main advantages of outsourcing user testing. Testing platforms such as PickFu understand the nuances of testing and handle the busy work so you don’t have to.
