ScalaTest Junit 5 runner

JUnit 5 runner library for ScalaTest tests. It can be used to fully integrate ScalaTest into Gradle (version >= 4.5) and to Maven.

There is an open issue to natively support JUnit 5 in ScalaTest without this library.

Getting Started

Features

• Running ScalaTest test on the Junit 5 platform
• Fully integrate ScalaTest into gradle
• Report individual test runs
• Report errors to JUnit 5 with stack traces
• Support ScalaTest tags
• Optional early stopping after the first test fail

How to use

Gradle

version >= 4.5 This library allows to run ScalaTest on the new JUnit Platform (JUnit 5) To run ScalaTest on the old JUnit Vintage (JUnit 4) platform use the gradle-scalatest Gradle plugin.

Groovy

gradle.properties

scala_lib_version=2.12
scala_version=2.12.10
junit_platform_version=1.6.0

build.gradle

plugins {
    id 'scala'
}

repositories {
    jcenter()
}

dependencies {
    implementation "org.scala-lang:scala-library:$scala_version"

    testImplementation "org.scalatest:scalatest_$scala_lib_version:3.2.0-M3"
    testRuntime "org.junit.platform:junit-platform-engine:$junit_platform_version"
    testRuntime "org.junit.platform:junit-platform-launcher:$junit_platform_version"
    testRuntime "co.helmethair:scalatest-junit-runner:0.1.11"
}

test {
    useJUnitPlatform {
        includeEngines 'scalatest'
        testLogging {
            events("passed", "skipped", "failed")
        }
    }
}

Kotlin DSL

    test{
        useJUnitPlatform {
            includeEngines("scalatest")
            testLogging {
                events("passed", "skipped", "failed")
            }
        }
    }
}
