User tests help to identify usability problems of an interface in real-life situations. They are carried out as close as possible to reality by putting oneself in the shoes of Internet users or Used to describe a service available on a mobile phone, laptop…... users. User Experience Testing (UX) consists of identifying blocking points with designers, developers, or business teams.
When to carry out user tests?
A method of evaluating a product by having it tested by end users (non-professional testers).... is considered an essential step from the product design stage. Its can be carried out at different critical points in the development process:
- At the ideation of the project/functionality by testing “paper” mock-ups
- During the graphic design process by checking the designers’ mock-ups
- With semi-functional mock-ups to validate predefined routes (directed navigation)
- Based on prototypes allowing to test the different scenarios with more liberties
- Finally, during the acceptance tests (UAT), before going into production, the usability tests will allow us to fine-tune the final settings.
These moments are the most efficient to evaluate the usability of a website or an application. Because they allow you to directly observe how the user interacts or behaves with the app. Thus designers can study the difficulties encountered by users. Usability problems are, therefore, addressed before deployment.
Of course, if the app does not seem to meet the objectives, it may be interesting to launch tests after production. The brand will then have structured REX (Return of Experience) to study.
The 4 objectives of the user test
The user test allows to measure four points of magnitude and to output an excellent analysis of the product to be tested :
- Performance: is the tool performing well enough? Are the steps clear? How long does it take to complete a simple task? Is it easy to find a product or create an account? Is the user able to buy the product without complications?
- Accuracy: is the tool accurate enough? How many bugs do test users encounter? Were they prohibitive, blocking or passing, major or minor?
- Recall: Is the product relevant enough? Will the user remember an item or information after the test? Or after a certain amount of time of non-use.
- The emotional response: Is the product comfortable enough? How does the user feel about the website/application? Confident, stressed? Could the user recommend the product?
User testing is a fundamental process that addresses the marketing analysis, development, and design concerns that arise during interface design.
