You can invest money in Android app development for your business, run it, but contrary to expectations, get negative reviews and sales decline. Such situations occur when the developer misses an important stage ー UI testing.
After the design is created, you need to make sure that the app will be clear and useful to the user. To do this, before launching the app, you need to conduct UI testing, that is, check the user interface. Some companies neglect this check. Release the beta version, track user reviews and modify the main version. But this method does not work if the problem goes beyond the interface details, and users do not understand how it all works.
User Interface Testing
What does the interface look like? Is it convenient for the user to press buttons? Whether icons are clear, whether the text, a format, a font is readable? These questions must be asked during Android app development. The appearance of the app should contribute to the convenience and clarity of the product. Color used as a functional element and cause positive emotions.
During the test interface, you simulate the actions of the user app. The task of such testing is to ensure that all system components interact correctly with each other.
It is advisable to carry out UI testing at the initial stage of developing a mobile app, at the prototype stage. Simultaneously with the testing of the interface, you conduct UX-testing, that is, you determine how a person feels when interacting with the app.
UI testing – why do you need to test the prototype
Testing prototypes help save time and money, as well as increase app reliability. Making changes to the app at the prototyping stage is much cheaper than when the product is drawn, laid out and programmed, especially if the prototype exists only on paper.
UI testing helps to check most of the user’s actions, the interaction of services and components
Some developers believe that it is better to conduct tests on the final version of the app because it is already a working system. Therefore, the results will be more reliable. But this is a risky approach. The customer can lose money if it turns out that at the very beginning the designers made a mistake.
Testing the prototype can be carried out by employees of a mobile application development company. The main thing is that these were not the people who are involved in the project.
You can test both static (paper) and interactive prototypes. In each case, UI testing has different tasks.
Paper Prototype Testing
Such tests are suitable for concepts and products with a large number of screens and buttons. Several people such as the target audience of the product should be involved while making the test. Of course, such a prototype is far from a real product, and the procedure itself does not look like a realistic verification of an interactive prototype. Nevertheless, UI testing will help identify problems of functionality, navigation, design and ultimately save the customer’s money.
Pros of working with paper prototypes
The main advantage is time-saving. You can draw a paper prototype in a couple of hours while creating an interactive prototype will take a couple of days.
If during testing, the developer understands that something is not working as it should, everything can be quickly corrected with paper and pen.
An example of testing a custom paper interface:
• The design of the mobile application is created on paper. One of the developers, who know the layout well, acts as a computer. He lays out the sheets with the layout near the test. As soon as the user clicks on the paper “screen”, the “computer” displays the page he needs.
• “Computer” notifies the user when the operation is completed. You can use a specific gesture or a printed icon as a signal.
• The person who conducts testing does not comment on his actions and design to the person being tested.
Although paper prototype testing is simpler and cheaper, many App developers test interactive prototypes. These are exact prototypes, most of the elements on which are clickable. The use of interactive prototypes reduces the likelihood of errors, since there is no need to imitate the operation of the system, as is the case when testing inaccurate paper prototypes.
UI-testing interactive prototype
Such tests are suitable for testing simple logic and identifying user expectations. But here, too, difficulties arise: in 8 out of 10 cases. The respondents find it difficult and they have to be reminded that they work only with the prototype at all time.
They follow a series of processes to obtain results of the actions of real users. On the basis of the obtained results, they draw conclusions and, if necessary, introduce changes to the design.
Is it always necessary to conduct UI- testing
Testing the user interface makes sense only for large applications. Therefore, before deciding which tests to conduct, App developers determine the size of the application. For short-term or small programs, they limit themselves to the Unit test (check that the services and components work and perform their tasks) and the E2E test (this test is similar to the UI, but is carried out with real services).
The main task of App developers from top app development companies is to release a useful, functional and user-friendly product. For this, they use all possible tools, but they use them justifiably.
