As per reference link, it.launcher and it.tests are related to server side unit tests. When we are running maven command (mvn clean install -PautoInstallPackage), it just runs the jUnit tests inside core bundle.
I tried to search for logs of AEM, don't find any of log statements from server side unit tests in logs.
What is the use of it.launcher and it.tests folders and when are these tests run on server (Do we need to have some extra configuration for these), these don't seem to be running while installing package on AEM.
Thank you for your response. The way you shared is one way to test the Model classes (inside core folder). it.launcher and it.tests folders are still not clear, what is the use in project structure and when they are run.
