@proldan please check your changes, some tests are failling

The be_empty matcher should also work for collections (anydata). Can you add that so the matcher is complete?

For anydata, if the type is object, the matcher should fail with error that the matcher cannot be used on objects but only on collections.

@Pazus what tests failed? The ones on the be_empty matcher or other ones? I had some problems installing develop version on my db and scheman and I can't execute some of them...

@jgebal Thanks! The matcher should fail with objects and any other type except sys_refcursor, right?

The matches schuld succeed for empty dataset in ref cursor and for empty collecion passed to the matcher as anydata

Corrected! Travis CI build passed and I added support for collections

Thanks, @proldan . Merged.
