cucumber-jvm/examples/spring-txn isn't really run

[christianhujer]

Describe the bug
cucumber-jvm/examples/spring-txn isn't really run. When you run mvn package or mvn verify there, the report is as follows:

[INFO] -------------------------------------------------------
[INFO]  T E S T S
[INFO] -------------------------------------------------------
[INFO] 
[INFO] Results:
[INFO] 
[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

This means that the tests aren't really run.
(Also, there is no output from Spring.)

To Reproduce
Steps to reproduce the behavior:

1. git clone cucumber-jvm
2. cd cucumber-jvm/examples/spring-txn
3. mvn package

If you like, modify src/test/java/io/cucumber/examples/spring/txn/SeeMessagesStepDefinitions.java and insert org.junit.jupiter.api.Assertions.fail(); as the first statement in method there_is_a_User().

Expected behavior
Tests are run.

Context & Motivation
I wanted to use test isolation via Spring transactions in a project and couldn't get it running, so I thought of checking the Cucumber example, and that's when I figured that the Cucumber example for how to do this actually isn't run.

Screenshots
If applicable, add screenshots to help explain your problem.

Your Environment

• Versions used: Cucumber 5.4.2
• Operating System and version: Ubuntu 18.04.4 LTS
• Build tool: Apache Maven 3.6.3

Workaround (also possible solution)

1. Point the Maven Surefire Plugin to version 3.0.0-M4
2. Add a dependency (to the normal bom, not the plugin) for org.junit.platform:junit-platform-commons:1.6.0
   Now the tests are running as expected (and they pass).
