Error: Unable to find @SpringBootConfiguration when doing @WebMvcTest for Spring Controller

Question

I am testing my controller given below

@Controller
public class MasterController {

@GetMapping(\"/\")
public String goLoginPage(){
    return \"index\";
}
}         


        

Answer 1

I had the same error, and found that when I had generated the project my pom.xml showed my groupId as com.example rather than with my actual domain:
com.example
I corrected the pom.xml to be:
com.mydomain
Next, I changed the file structure from:
src/test/java/com/example to src/test/java/com/mydomain
Last, I had to update the package declaration inside my
SampleProjectApplicationTest.java
file to match the correct file structure. Once that was all in place, the tests worked fine.

I am not sure how I ended up with com.example where the rest of my project was correct, but the fix was that simple in my case.

Hopefully this helps someone.
