JUnit and Gradle

The only configuration required to enable unit testing in a Gradle project is to apply the Java plugin and declared JUnit as testImplementation:

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    ...
    testImplementation "junit:junit:4.12"
}

This will allow to declare @Test methods and will enable result parsing to generate HTML reports.
