Can't get the test to run

[Vance]

I'm unable to get the 'ApplicationTest' class to run successfully. I'm getting the following error message when I try to run it within Eclipse:

Hi @aroc725. I went through the guide today and I could not reproduce this error. There have been many changes to the guide since your original issue was filed and I expect in one of those the issue was fixed.

On first glance, perhaps the issue was related to this question in Stack Overflow. Note that junit-jupiter-engine is a managed dependency from Spring Boot. You could also verify that junit-jupiter-engine is on the classpath by running the command ./mvnw dependency:tree | grep 'jupiter-engine'

I will close the issue for now, but please reply if this is still an issue with the guide.
