how is java annotation represented in java bytecode

Question

I tried to decompile a .class file that contains JUnit tests. I read the byte code, but I did not see any clue of the @Test annotation(it's used in the java source code).

As metadata, how are annotations represented in bytecode?

Annotations appear just before the byte code of the thing it is associated with. If you are not seeing the annotations it could be an old de-compiler (most of them are)

I used JBVD. What are the new ones that are able to decompile annotations?

I use ObjectWeb's ASM, this is not a de-compiler but reads everything which is there.
