Basically I just would like to test my mapper which should be auto generated by MapStruct.
I tried all annotations possible and this answer seems to be the best solution in order to work with sprinboot and junit 5 although it still does not work in my eclipse, somehow it just shows an error as seen below saying ProductMapperImpl cannot be resolved to a type although it should be autogenerated trough @Mapper annotation.
For example I am also using Lombok Annotation and all these auto generated methods eclipse recognizes and works absolutely fine.
So what did I do wrong? Maybe there is another way to autowire mapper interface to test class so that it works? Maybe it is something with the generated-sources folders and just eclipse somehow not recognizing it?
