Does anyone know of any software to let you test relational algebra queries? By this I don't mean a database such as MySQL, something where the query can be input in some for of mathematical notation instead of SQL.

If you have any experience with programming languages such as Haskell or any of the ML-variants you could just use lists and map/filter/fold. Testing queries could then be achieved by using a testing framework such as QuickCheck (assuming you by "test" mean something like checking the result of a "query" satisfy some properties).
