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.
Following Andrii Karaivanskyi's answer here's the Maven POM declaration:
...
5.2.0
1.2.0
...
...
org.junit.jupiter
junit-jupiter-engine
${junit-jupiter.version}
test
org.junit.platform
junit-platform-launcher
${junit-platform.version}
test
...
UPDATE
As per comment by Alexander Wessel you can use org.junit:junit-bom as described in his answer to question Eclipse No tests found using JUnit 5 caused by NoClassDefFoundError for LauncherFactory.
