Join Chiu-Ki Chan for an in-depth discussion in this video Why test?, part of Effective Android Testing for Mobile Developers.
- [Instructor] When you write an Android app, you need to check that it is working as expected. One way to do that, is to manually go through scenarios clicking buttons, typing tests just like new users do. However, that is very tedious. Automated testing allows you to execute and verify your app automatically. Most people think of testing as a way to catch bugs but writing a testable app needs proper separation of concerns, which means you will end up with highly modular code.
And with proper architecture, testing allows you to implement features faster. You can use mocks to set up your app to a certain state and write new code for that part of the app directly rather than clicking and typing to reach a certain screen and repeating again and again, as you make adjustments. In this course, we are going to look at different types of tests and build an app together to try out all the different techniques
