But general interface is independent. 15:39:32 http://www.w3.org/2005/rules/wg/wiki/Arch/Test_Cases 15:40:52 Adrian: Ex. in section "Categories of RIF Dialect test cases" at above URL. 15:41:20 ... Can test if all test cases succeed. 15:41:45 Do you have something like SPROT in mind? i.e. we'd need to define an interface, result format, etc. 15:41:50 ... E.g. built-in tests ares done in each rule engine, reached from the interface. 15:41:58 -StellaMitchell 15:42:03 sorry, wrong button 15:42:10 calling back 15:42:13 s/ares/are/ 15:42:49 Chris: Time and bandwidth?

Corner cases of BLD and PRD. 15:47:20 Adrian: The idea is that only the interface is given, from which specific ones are generated. 15:47:37 Chris: Tricky to do test cases for an interchange format. 15:47:57 Adrian: Idea like for Built-ins. Library + Specific. 15:48:33 ... Could also contribute to use case doc with Stella. But first place in my priorities is PRD. 15:48:40 Chris: OK 15:49:02 Gary: E.g. you could write ground facts and rules and test these. 15:49:04 here are some examples http://www.w3.org/2005/rules/wiki/Category:Test_Case 15:49:25 Chris: Not so much translation test cases. 15:49:59 Gary: Right. Need entailment test to help with understanding spec. 15:50:09 By entailment tests we mean just *qround* queries? but no non-ground queries? 15:50:14 Christian: We need to make sure that what we specify works. 15:50:22 ... need exanples. 15:50:46 Gary: Yes, good test cases can show model-theoretic semantics. 15:50:57 ... another way to show the implementation. 15:51:39 Christian: We should have test cases but they cannot say how things must be. 15:51:48 ... You have to say something about semantics. 15:52:00 Chris: No one is for translation test cases? 15:52:22 Christian: Well, we need them but it's tricky: Several ways to translate some rules. 15:53:12 Chris: Just want to clarify if test cases are for exemplifying entailments or translations. 15:53:38 Christian: Mostly translation. Semantics must be linked to translation, too. 15:53:42 If Stella is interested in help, I could help out. 15:54:13 Chris: Any one else interested become a test cases co-editor?
