How to Design Android APP Test Cases

Developing an application is a stressful job. No one is perfect. It is normal to encounter bugs at work. Some programmers will be angry, frustrated, depressed, and even discouraged, while some programmers will be calmer.

How to go about the bug-fixing process is the value of an app's success in today's competitive market without a solid user interface. Therefore, thorough testing of UIs with some special attention and care for functionality and user experience is essential.

The challenge becomes even more complicated when it comes to the Android platform and the number of unique problems it poses (Android presents significant UI challenges). The keyword "fragmentation" symbolizes the biggest obstacle to comprehensive testing of mobile applications, and also indicates the difficulties caused by Android devices of all shapes, sizes, and configuration types released to the market. This article will show how the Android emulator can provide extensive testing covering a large number of device types using a few tricks and simple practices.

One of the biggest challenges that the average Android developer faces in their day-to-day work is the wide range of end devices and OS versions. With thousands of different new devices coming to market every year, this is a growing challenge.

From the perspective of a mobile APP development, the definition of terminal equipment has four basic characteristics:
　　
Operating system: Android operating system version (1.1 ~ 4.3) professionally defined by "API indicators".

Display: A screen is primarily defined by screen resolution (in pixels), screen pixel density (in DPI), and/or screen size (in inches).

CPU: The "Application Binary Interface" (ABI) defines the instruction set of the CPU. The main difference here is ARM and Intel-based CPUs.

Memory: A device includes predefined heap memory of internal memory (RAM) and Dalvik virtual memory (VM heap).

Mobile apps must provide the best user experience and be displayed correctly on a variety of smartphones and tablets of different sizes and resolutions. At the same time, it must pass the app functional test And compatibility testing to ensure that as many device specifications as possible can be used normally.

Used in the right way, tests can be a powerful tool in the battle against fragmented Android. The key to an effective testing strategy is to define custom test cases for the app at hand and define a workflow or process that simplifies testing. Testing a mobile app is a major challenge, but it can be effectively tackled with a structured approach and the right set of tools and expertise.
