Ahven is a simple unit test library (or a framework) for Ada programming language. It is loosely modelled after JUnit and some ideas are taken from AUnit.

Ahven is free software distributed under permissive ISC license and should work with any Ada 95, 2005, or 2012 compiler.

Ahven 2.7 compiles and passes its test suite on following platforms

Ahven 2.7 (2018-07-24) This is a minor maintenance release with some new features. In addition to existing comfignat based system, there is now very simple GNAT project file provided for Ahven library. The framework internals also got some performance increases and smaller memory usage for each test. Set_Up and Tear_Down procedures got improvements and fixes.

Ahven 2.6 (2015-08-30) This release fixes release dates mentioned in the documentation. Otherwise 2.6 is identical to 2.5.

Ahven 2.5 (2015-08-30) This is a minor maintenance release with some new features. The comfignat build system/Makefile is now default for GNAT. Other compilers use their own build mechanisms as before. In addition, some new command line options for the test runners were added, see the documentation for details. The hosting of Ahven's website and release files is changed to a dedicated site: http://www.ahven-framework.com/ Downloads from Sourceforge are no longer supported.

Ahven 2.4 (2014-02-09) This is a minor maintenance and bug fix release. Ahven now compiles cleanly with Apex Ada (no errors) and Irvine ICC Ada (no warnings). In addition, the documentation was improved and experimental comfignat-based build system was added.

Ahven 2.3 (2013-01-24) This is a minor feature release. Starting from this release, the exception backtraces are now stored to the test results and printed out along with the results. In addition, the documentation received some improvements and output of multiline messages from TAP_Runner was fixed.

Ahven 2.2 (2012-03-05) This is a bug fix release. The release fixes the reporting of skipped tests in Ahven.XML_Runner. Also, support for GNAT 3.15p was removed. Documentation generation tool was changed from Adabrowse to Sphinx.

Ahven 2.1 (2011-09-24) This is a bug fix release. The release fixes the skipped test reporting in Ahven.Text_Runner.

Ahven 2.0 (2011-09-23) This is a feature release. The release adds possibility to stop tests after certain amount of time and programmatically skip tests. In addition, the README document is now in reStructured text format, like the manual.

Ahven 1.9 (2011-04-19) This is a bug fix release. The release includes new HTML documentation generated from reStructured text using Python-Sphinx and fixes compilation problems with GNAT GPL 2010.

Ahven 1.8 (2010-06-02) This is a bug fix release. Changes include a fix for double free when mixing dynamic test cases with static test suites, removal of some unfinished features like TAP 1.3 and Janus/Ada 3.1.1d support, and code cleanups.

Ahven website location changed again (2009-11-30) The website location of Ahven changed once more. This time the change should be the last one for a while. At the same time, the layout was reverted to the older version, which is more friendly to the bandwidth. Technical detail which should be interesting: The new website is running on Debian and Ada Web Server.

Ahven 1.7 (2009-09-14) This is a bug fix release. Changes include a fix for Constraint_Error with long test names and special character filtering from the test names when generating XML results. In addition, PDF report generation example was added to the contrib directory and some internal code cleanups were done.

Mercurial repository, part 2 (2009-06-25) Sourceforge.net has had some problems with their Mercurial repositories, so now the previously unofficial Bitbucket Mercurial repository as the official Mercurial repository for Ahven. Also, bug reports are now at Bitbucket.

Mercurial repository (2009-03-17) Sourceforge.net added support for Mercurial and now Ahven's source code repository is migrated from CVS to Mercurial.

Ahven 1.6 (2009-02-28) This release fixes GNAT installation issues.

Ahven 1.5 (2009-02-23) This is first release at SourceForge. The release includes only some build system changes.

SourceForge.net (2009-02-18) Ahven project is now hosted by SourceForge.

Ahven 1.4 (2009-01-22) This release introduces Test Anything Protocol (TAP) reporter, a new API for stack-based test cases, and improved Janus/Ada support. Also, some API changes were done, but they should affect you only if you have extented the framework.

Ahven 1.3 (2008-08-13) A bug fix release. The major change is support for Janus/Ada. Web site layout changes (2008-06-30) The web site layout was changed to be "less boring". The new blueish theme should work better on different types of monitors. (Some low quality monitors and graphics cards didn't show light brown colors properly.)

Ahven 1.2 (2008-05-12) A major new feature in this release is support for JUnit-compatible XML-based test result format. The release also includes bug fixes and code cleanups.

Ahven 1.1 (2008-01-30) Incremental release including bug fixes and new features.
