Are there compatibility tests for the Java EE platform?
Yes. The Java EE Compatibility Test Suite (CTS) is available for the Java EE platform. The Java EE CTS contains over 5,000 tests for Java EE 5. The suite tests compatibility by performing specific application functions and checking results. For example, to test the JDBC call to insert a row in a database, an EJB component makes a call to insert a row and then a call is made to check that the row was inserted.
