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

Question

The problem

Whenever I run my projects JUnit test (using JUnit 5 with Java 9 and Eclipse Oxygen 1.a) I encounter the problem that eclipse can\'t find any tests.

Answer 1

I also faced the same issue you just need to add the library , Junit Library is already provided along with Eclipse so you just need to follow below

Build Path > Configure Build Path > library > Add library > JUnit > Next > finish

It works for me
