Test suites for Dialyzer
This is a transcription of most of the cvs.srv.it.uu.se:/hipe repository dialyzer_tests into test suites that use the test server framework. See README for information on how to use the included scripts for modifications and updates. When testing Dialyzer it's important that several OTP modules are included in the plt. The suites takes care of that too.

+%%---------------------------------------------------------------------
+%% This module does not test gb_sets. Instead it tests that we can
+%% create records whose fields are declared with an opaque type and
+%% retrieve these fields without problems. Unitialized record fields
+%% used to cause trouble for the analysis due to the implicit
+%% 'undefined' value that record fields contain. The problem was the
+%% strange interaction of ?opaque() and ?union() in the definition of
+%% erl_types:t_inf/3. This was fixed 18/1/2009.
