Junit5 with IntelliJ and Gradle

Adding specific dependencies solve the problem.

NOTE: UPDATE INTELLIJ ABOVE 2017.2.0 AS THERE WAS A BUG WITH THE JUNIT LAUNCHER

OXYGEN if you using eclipse.

---

Below dependency enables Junit5 parametrized tests which can be used instead of a DataProvider.

"org.junit.jupiter:junit-jupiter-params:5.0.0"
//for JUnit5 parametrized tests.

---

Junit5 API.

"org.junit.jupiter:junit-jupiter-api:5.0.0"
//JUnit5 API

---

Needed if you want to run legacy JUnit4 tests without changing the syntax and imports.

"org.junit.vintage:junit-vintage-engine:4:12.0"
//for legacy JUnit4 tests

EDIT: 07/2018 Match the version of the vintage runner to the jupiter version

---

Needed if you want to run JUnit5 tests with new syntax and imports.

"org.junit.jupiter:junit-jupiter-engine:5.0.0"
//for JUnit5 tests

java.lang.NoSuchMethodError: org.junit.platform.engine.EngineDiscoveryRequest.getDiscoveryFiltersByType(Ljava/lang/Class;)Ljava/util/List;

---

Launcher.

"org.junit.platform:junit-platform-launcher:1.0.0
//to handle default launcher

Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.getDefaultClassLoader()Ljava/lang/ClassLoader;

Additional info how to install JUnit5

---

Since version 4.6 for Gradle, there is no need for plugins anymore Gradle supports Junit5 natively just do: And the version of the vintage runner is now same as the JUnit 5 version.

dependencies {

    testImplementation "org.junit.jupiter:junit-jupiter-params:$junitVersion"
    testImplementation "org.junit.jupiter:junit-jupiter-api:$junitVersion"

    testRuntimeOnly "org.junit.vintage:junit-vintage-engine:$junitVersion"
    testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine:$junitVersion"
}

test {  
    useJUnitPlatform {
        includeEngines 'junit-jupiter', 'junit-vintage'
    }
}

I have to change the version of JUnit from 5.4.0 for 5.3.2 and it works like a charm.

The configuration I use is below.

The vintage engine dependency is only required if you are using junit4 tests as well.

The jupiter params is only required if using parameterised tests.

    <junit.version>5.0.0</junit.version>
