Join Chiu-Ki Chan for an in-depth discussion in this video Dependency injection, part of Advanced Android Espresso Testing.
- [Instructor] How can we write tests…for a time-dependent app that has repeatable results?…We can use the dependency injection pattern.…Dependency injection is a way to organize your code.…We collect all the external dependencies in one place.…In the app, we use the actual external dependencies.…In our example, we are going to use the current time.…During testing, however, we swap them out…with implementation that we control.…
In this example, instead of using the current time,…we will supply a fixed time so that we know…what the UI should display given that time.…Next, we will change our app to use dependency injection.…
