Existing Project

Basic usage of the existing testing project requires no special setup, as it was created as a JUnit5 test project in the first place; review the JUnit5 documentation for detail-in-depth.

Creating a New Project

If a new testing project needs to be created, here is a quick-and-dirty rundown:

• Add the following block of code to the project build.gradle file, before the plugins { ... } block

  • buildscript {
        dependencies {
            classpath("de.mannodermaus.gradle.plugins:android-junit5:1.8.2.0")
        }
    }

    • Change 1.8.2.0 (plugin version number) as necessary.

• Add the following line of code to the project build.gradle file, between the android { ... } and dependencies { ... } blocks:

  • apply plugin: 'de.mannodermaus.android-junit5'

• Add the following block of code to the project build.gradle file, in the existing dependencies { ... } block (not the one in the buildscript scope, but the one that is its own scope, following the apply plugin line):

  • dependencies {
        testImplementation "org.junit.jupiter:junit-jupiter-api:5.3.2"
        testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine:5.3.2"
        testImplementation "org.junit.jupiter:junit-jupiter-params:5.3.2"
        
        // other dependencies...
    }
