Unit Testing in Android
Explore how to implement unit testing in Android applications with the JUnit framework. Learn to write isolated tests for methods and classes, use common assertions, and test ViewModel functions to ensure code reliability.
Introduction
Unit tests are the smallest tests in Android. They’re used to test a method or class in isolation. If the method or class under testing has dependencies, we can provide mock implementations for them so that external factors don’t impact the test result.
In this lesson, we’ll learn how to set up and use the JUnit testing framework for unit testing in Android.
Gradle dependencies
We need to add the JUnit library dependency in the app/build.gradle file to start unit testing in our app.
Basics of unit testing
We can annotate the function with @Test ...
