Here are the 10 most popular mobile usability testing methods every QA tester should apprehend. 

1. Moderated Usability Testing

A moderated testing session comprises a moderator guiding participants through the test. This normally gives more in-depth results since the moderator can request more information and follow-up questions. Moderators can also ask participants to elaborate more on a critical response to discovering out how users feel about an app during various usage processes. You can have much control of the test flow and get more qualitative feedback.

Therefore, it is advised to run closely monitored testing like moderated ones when you need to find the reasoning behind user behavior. If you prepare to identify user behavior patterns, you can consider selecting unmoderated usability testing.

Unlike moderated testing, unmoderated usability testing needs members to accomplish all the tasks by themselves, without further instructions or interference from the moderator. Unmoderated testing is more time-effective and less expensive. It is perfect for testing users’ normal context when navigating an app. And it’s most fit if you want to work on large sample studies for more quantitative testing. 

Since unmoderated testing needs little, almost no supervision, you’ll require to ensure all the instructions are certainly given prior to the test. The majority of unmoderated testing is performed remotely, creating a stable internet connection a top preference for the test participants’ environment. 

3. Lab Usability Testing

Lab usability test asks participants to perform particular tasks instructed by a trained moderator within a purposely-designed laboratory. There are two rooms separated by a one-way mirrored window to provide note-takers to see the test without being seen by participants and influence the results. The moderator will ask questions, provide instructions, and answer feedback in real-time, similar to moderated testing discussed earlier. You may also record the session for additional review and analysis afterward.

The main benefit of lab usability testing is that it gives standardized quality control for each administered test. This is especially crucial if you plan to run comparison usability testing. In addition, lab usability testing allows extensive user information about how users are experiencing your product. You’ll be capable to get more valuable insights like users’ attitudes, emotions, and reactions. 

4. Guerilla usability testing

For guerilla usability testing, participants are regularly picked randomly from a public place, like a coffee shop, mall, airport, or supermarket, and asked to conduct a short usability test in exchange for small prizes such as gift cards or coupons. 

Guerrilla testing is often managed among a broad range of people that don’t have a history with a product previously. It seldom serves as an ad-hoc test for the UI/UX team to learn the functionality and design. If you intend to collate massive qualitative data fast, guerrilla testing is one of the methods. It provides your app with more brand exposure before it really hits the market. You can also collect more real user feedback in a less formal setting. 

5. Contextual Inquiry

The contextual inquiry method applies to recognizing how participants interact with the product in their original environments such as offices or homes. The researchers will then observe how participants perform a task and invite their reasons behind their actions to gain a broader understanding of the user behavior. 

This method is an outstanding way to recover reliable information about users, including work preferences, personal behavior, and the situations required for the product. These insights are required at the initial stage of production as you’ll require as much data on personas, content, features requests, and architecture as possible. Once you release a product, you can also utilize contextual inquiry to test whether your design really matches users’ requirements. 

When managing contextual inquiry testing, you require to assure these four following principles:

  • Ensure the test is managed under the user’s natural environment
  • Researchers should operate with the test participant to respond to any questions they have throughout the process, recognize their behavior, and discuss the reasons behind their actions. 
  • Ensure your research goal and questions are apparent to reach more unbiased results.
  • During the interview, researchers should give their opinions and interpretations to the user to receive a more holistic view of the complete user testing process.
