ClassCastException: class io.quarkus.test.common.TestResourceManager cannot be cast to class io.quarkus.test.common.TestResourceManager

[tarilabs]

Describe the bug

Inadvertently mixing @QuarkusTest and @QuarkusIntegrationTest by inadvertently naming convention of the classname, results in ClassCastException

Expected behavior

As allegedly is a known expectation not to mix it,
ref https://github.com/kiegroup/kogito-runtimes/pull/1757#discussion_r759158629

It would be ideal if a WARN message is produced even by heuristic, something ~like: "WARN It seems you are mixing @QuarkusTest and @QuarkusIntegrationTest while running them with the Maven Failsafe plugin, and this might result in unexpected and unsupported behaviour"

Actual behavior

For SEO purposes, might this help someone reach to this report and save some time by noticing they might have as well mixed Test Vs IT by means of mixing annotation / classname / filename

How to Reproduce?

checkout https://github.com/tarilabs/demo20221012-testit

mvn clean install

CCE is reproduced per stacktrace above.

Output of uname -a or ver

No response

Output of java -version

No response

GraalVM version (if different from Java)

No response

Quarkus version or git rev

No response

Build tool (ie. output of mvnw --version or gradlew --version)

No response

Additional information

I would be happy to discuss how to potentially address this for DX, given it took me a while myself to figure out what was I doing wrong in my (more complex) application code.

Good idea about providing a hint!

#28537 takes care of it
