Understanding Multi-project Test Dependencies with Gradle

Building software now generally involves managing multiple modules or projects within a single repository (a monorepo). Gradle is a versatile build tool that efficiently manages dependencies, including the complexities of multi-project builds. In this article, we'll explore how to handle test dependencies across multiple projects using Gradle.

The Basics of Multi-project Builds

In Gradle, a multi-project build is organized with a root project and one or more subprojects. Here's a simple structure:

1my-multi-project/
2| -- build.gradle | -- settings.gradle | -- subprojectA/ |  | -- build.gradle | -- subprojectB/ |  |
3| --- | --- | --- | --- | --- | --- | --- |
4| **Settings** | Define projects in `settings.gradle` |
5| **Dependencies** | Use `implementation` and `testImplementation` for cross-project needs |
6| **Task Execution** | Leverage `dependsOn` for correct execution order |
7| **Customization** | Use `useJUnitPlatform()` and `testLogging` for test runs |
8| **Aggregation** | Combine reports with a custom `TestReport` task |
