   Systematic regression tests have been introduced to isac development in 2003.

   Sanity of the regression tests suffers from updates following Isabelle development,

   which mostly exceeded the resources available in isac's development.

   The survey below shall support to efficiently use the tests for isac 

   on different Isabelle versions. Conclusion in most cases will be: 

   !!! Use most recent tests or go back to the old notebook

       with isac on Isabelle2002. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 subsubsection {* State of tests *}

 text {*

   At least the tests from isac on Isabelle2011 run again.

   However, Test_Isac.thy shows erratic behaviour; no errors are obtained when scrolling 

   in parallel with evaluation.

   Counting "error in kernel" for Frontend/interface.sml (the tests considered most significant)

   yields 69 hits, some of which were already present before Isabelle2002-->2009-2

   (i.e. on the old notebook from 2002).

   Now many tests with (*...=== inhibit exn ...*) give a reason or at least the origin:

   # === inhibit exn WN1130621 Isabelle2012-->13 !thehier! === ...see Build_Thydata.thy

   # === inhibit exn AK110726 === ...reliable work by Alexander Kargl, most likely go back to 2002

   # === inhibit exn WN1130701 broken at Isabelle2002 --> 2009-2 === , most likely go back to 2002

   Reasons for outcommented tests are also found in Test_Isac.thy near the respective file.sml.

   Some tests have been re-activated (e.g. error patterns, fill patterns).

   isac's mathematics engine has been extended by two developments:

   (1) Isabelle's contexts were introduced by Mathias Lehnfeld

   (2) Z_Transform was introduced by Jan Rocnik, which revealed

     further errors introduced by (1).

   (3) "error patterns" were introduced by Gabriella Daroczy

   Regressions tests have been added for all of these.

 text {* 

   Systematic efforts outcommented less significant tests by (*...=== inhibit exn ...*) 

   and sometimes give reasons for failing tests.

   (*...=== inhibit exn AK...*) was done by Alexander Kargl; this is reliable

   work, some of which couldn't be revised (and renamed) by WN and thus survived some time.

   The most signification tests (in particular Frontend/interface.sml) run,

   however, many "error in kernel" are not caught by an exception.

 subsubsection {* Summary of development *}

 text {*

   In 2009 the update of isac from Isabelle2002 started with switching from CVS to hg.

   The update was painful (bridging 7 years of Isabelle development) and cut short 

   due to the start of introducing Isabelle's contexts (Mathias Lehnfeld) and

   going on to Isabelle2011 although most of the tests did not run.

 subsubsection {* Run tests *}

 text {*

   WN131021 this is broken by installation of Isabelle2011/12/13,

   because all these write their binaries to ~/.isabelle/heaps/..

   $ ./bin/isabelle emacs -l HOL src/Tools/isac/Build_Isac.thy

   $ ./bin/isabelle emacs -l Isac src/Tools/isac/Test_Isac.thy

   NOT THE RIGHT VERSION.....    test/Tools/isac/Test_Isac.thy !!!
