# android-junit5 [![CircleCI](https://circleci.com/gh/mannodermaus/android-junit5/tree/master.svg?style=svg)][circleci]

![Logo](.images/logo.png)

A Gradle plugin that allows for the execution of [JUnit 5][junit5gh] tests in Android environments using **Android Gradle Plugin 3.2.0 or later.**

## How?

This plugin configures the unit test tasks for each build variant of a project to run on the JUnit Platform. Furthermore, it provides additional configuration options for these tests [through a DSL][wiki-dsl] attached to `android.testOptions`.

Instructions on how to write JUnit 5 tests can be found [in their User Guide][junit5ug].
Furthermore, this repository provides a small showcase of the functionality provided by JUnit 5 [here][sampletests].

}
```

More information on Getting Started can be found [on the wiki][wiki-gettingstarted].

## Requirements

The latest version of this plugin requires:
* Android Gradle Plugin `3.2.0` or above
* Gradle `4.7` or above

## Instrumentation Test Support

There is experimental support for Android instrumentation tests, which requires some additional configuration & dependencies. Furthermore, because JUnit 5 is built on Java 8 from the ground up, its instrumentation tests will only run on devices running Android 8.0 (API 26) or newer. Older phones will skip the execution of these tests completely, marking them as "ignored".

To start writing instrumentation tests with JUnit Jupiter, make the following changes to your module's build script:

<details open>
<summary>Groovy</summary>

```groovy
android {
defaultConfig {
// 1) Make sure to use the AndroidJUnitRunner, of a subclass of it. This requires a dependency on androidx.test:runner, too!
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
// 2) Connect JUnit 5 to the runner
testInstrumentationRunnerArgument "runnerBuilder", "de.mannodermaus.junit5.AndroidJUnit5Builder"
}

// 3) Java 8 is required
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}

// 4) JUnit 5 will bundle in files with identical paths; exclude them
packagingOptions {
exclude "META-INF/LICENSE*"
}
}

dependencies {
// 5) Jupiter API & Test Runner, if you don't have it already
androidTestImplementation "androidx.test:runner:${Versions.androidx_test_runner}"
androidTestImplementation "org.junit.jupiter:junit-jupiter-api:${Versions.org_junit_jupiter}"

// 6) The instrumentation test companion libraries
androidTestImplementation "de.mannodermaus.junit5:android-test-core:${instrumentationVersion}"
androidTestRuntimeOnly "de.mannodermaus.junit5:android-test-runner:${instrumentationVersion}"
}
```
</details>

<details>
<summary>Kotlin</summary>

```groovy
android {
defaultConfig {
// 1) Make sure to use the AndroidJUnitRunner, of a subclass of it. This requires a dependency on androidx.test:runner, too!
testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
// 2) Connect JUnit 5 to the runner
testInstrumentationRunnerArgument("runnerBuilder", "de.mannodermaus.junit5.AndroidJUnit5Builder")
}

// 3) Java 8 is required
compileOptions {
setSourceCompatibility(JavaVersion.VERSION_1_8)
setTargetCompatibility(JavaVersion.VERSION_1_8)
}

// 4) JUnit 5 will bundle in files with identical paths; exclude them
packagingOptions {
exclude("META-INF/LICENSE*")
}
}
dependencies {
// 5) Jupiter API & Test Runner, if you don't have it already
androidTestImplementation("androidx.test:runner:${Versions.androidx_test_runner}")
androidTestImplementation("org.junit.jupiter:junit-jupiter-api:${Versions.org_junit_jupiter}")

// 6) The instrumentation test companion libraries
androidTestImplementation("de.mannodermaus.junit5:android-test-core:${instrumentationVersion}")
androidTestRuntimeOnly("de.mannodermaus.junit5:android-test-runner:${instrumentationVersion}")
}
```
</details>

The `android-test-core` artifact includes an extension point for the `ActivityScenario` API; more information on that can be found in the wiki.

# Official Support

At this time, Google hasn't shared any immediate plans to bring first-party support for JUnit 5 to Android. The following list is an aggregation of pending feature requests:

- [InstantTaskExecutorRule uses @RestrictTo(RestrictTo.Scope.LIBRARY_GROUP) -- why? (issuetracker.google.com)](https://issuetracker.google.com/u/0/issues/79189568)
- [Add support for JUnit 5 (issuetracker.google.com)](https://issuetracker.google.com/issues/127100532)
- [JUnit 5 support (github.com/android/android-test)](https://github.com/android/android-test/issues/224)

# Building Locally

This repository contains multiple modules, divided into two sub-projects. The repository's root directory contains build logic shared across the sub-projects, which in turn use symlinks to connect to the common build scripts in their parent folder.

- `instrumentation`: The root folder for Android-based modules, namely the instrumentation libraries & a sample application. After cloning, open this project in Android Studio.
- `plugin`: The root folder for Java-based modules, namely the Gradle plugin for JUnit 5 on Android, as well as its test module. After cloning, open this project in IntelliJ IDEA.
