Eclipse No tests found using JUnit 5 caused by NoClassDefFoundError for LauncherFactory

java eclipse junit junit5

I fixed the issue by right clicking the test and selecting 'Run Configurations' and changing the "Test runner:" selection to 'JUnit 4' as shown here:

I ran the test again and it worked.

java eclipse junit junit5

I have the same issue with STS 3.9.1. It seems like an Eclipse bug, however, to fix this you can add a test dependency junit-platform-launcher to your project (https://mvnrepository.com/artifact/org.junit.platform/junit-platform-launcher)

This is how I did for my project which uses gradle:

dependencies {    // other stuff here    testCompile group: 'org.junit.jupiter', name: 'junit-jupiter-engine', version: "5.${junit5MinorVersion}"    testCompile group: 'org.junit.platform', name: 'junit-platform-launcher', version: "1.${junit5MinorVersion}"}

gradle.properties file:

junit5MinorVersion=1.0

I believe the same applies if you see this exception while using IntelliJ IDEA.

java eclipse junit junit5

In my case, the problem was myself and no IDE like Eclipse. I've imported the JUnit 4 Test class.

So do NOT import this one:

import org.junit.Test  // JUnit 4

But DO import that one:

import org.junit.jupiter.api.Test // JUnit 5
