Answer 1

I got the exact same error when the package name of a class was different from the package name of the integration test.
More specific, my class "GreetingController" was in folder
../src/main/kotlin/com/kotlinspring/controller
and my class "GreetingControllerIntegrationTest" was in folder
../src/test/integration/com/cotlinspring/controller.
I fixed it by renaming the misspelled "cotlinspring" to "Kotlinspring".

Answer 2

I had the same problem due to changing the directory path for my App file while forgetting to move the test to the same path. Check that you have both files (source and test) at the same path directory

Answer 3

I had the same problem. I thought something was wrong with my code. I searched for references to "getName" in the project, did some debugging and still couldn't figure out what was wrong. Changing the package name in test to the same package name as the project fixed it.

Answer 4

I was also facing the same issue , and renaming package didn't work for me .
But strangely providing the MainApplication class name in the #SpringBootTest Annotation , worked for me .
#SpringBootTest(classes = MainApplication.class)
I am not sure , how and why this works . But will try to figure this out and post the reason here
