Understanding how much of your code is being executed during unit testing is crucial in large-scale Android applications. In this final episode of the Android Unit Testing series, we take a deep dive into Jacoco — a powerful tool for measuring code coverage.

You’ll learn:
What Jacoco is and how it works
How to configure Jacoco in your Android project using Gradle
How to generate detailed HTML reports showing code coverage
How to interpret the Jacoco report to improve your test coverage

We also walk through a real project setup, showing you how to exclude generated classes, avoid configuration conflicts, and visualize which parts of your code are covered or missed by tests.

This video wraps up the fundamentals of unit testing in Android and sets the stage for advanced testing techniques in future content.
