How to use JUnit tests with Spring Roo? (Problems with EntityManager)

Question

I\'m trying to write a JUnit test for a Spring Roo project. If my test requires use of the entity classes, I get the following Exception:

java.lang.IllegalS         


        

Answer 1

This is an incredibly annoying problem with Spring Roo and I have not figured out the official solution for.

But ... here are two workarounds:

• Copy the spring-aspects jar to your project then add it to your Projects AspectJ Aspect Path
• Use Maven to run your unit tests (and miss the green bar :( )

For option one Right click on your project select Properties-> AspectJ Build -> Aspect Path Tab.
