Why is Android Unit Testing Important?
Software testing is often considered an underrated process in the software development life cycle as it is left in the later stages of the project. Many think that not writing any test is ideal for the application. In fact, there are many misconceptions regarding this. Some consider that a backend app should be tested as they are the one that carries real logic instead of frontend mobile apps. The other one is about the UI, which many consider as the logic point and that is why mobile apps are difficult to unit test. Moreover, people consider mobile apps as simple and tiny compared to backend apps.
Actually, with the advancement of technology, backend apps are growing bigger in size and complexity. Many companies have separate team focussing on a particular feature and there are other teams that merge all features and upload the final build. With code complexity and team collaboration, writing good test is very important as it can ease most of the things.
Three Tiers of Android Test Pyramid
This emulates the user behavior and interacts with the UI of the application. Since it requires a device to run, this proves to be quite slow and expensive. Some of the common tools that can be used are Espresso and UI Automator.
This doesn’t involve any UI complexity and allows you to see how your code interacts with the Android framework. However, it doesn’t require a device to run. The most commonly used tool is Roboelectric.
This allows you to focus on just one class under test. This doesn’t require a device and proves to be the fastest and least expensive. The most commonly used tool to perform unit test on Android is JUnit and Mockito.
Component and unit testing at 360logica Lab is an essential part of our commitment to follow the global delivery model and guarantee on-budget and on-time foreseeable software quality gains. Effective component testing by experienced software product testing experts at our lab makes sure each and every component of the software is tested for its quality, performance, and security and the application works to its full potential and bug-free in the real environment. We verify each part using established unit testing methods to find out potential liabilities of individual parts of an application and ensure each part is capable of doing its function and contribute to the overall performance.
360logica focuses on value proposition during software testing and assures customers that their applications are tested thoroughly. We fully recognize the importance of component testing and verify individual credentials as well as the performance of a component in the integrated setup. Every time a problem is found and rectified, components, as well as the entire system, are retested for its confirmation. Similarly, when a change is incorporated in the system, we track the test cases influenced by it and verify their efficacy.
