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.

• Simple API
• Small size (Ahven about has 3K SLOC)
• JUnit-compatible test results in XML format; this allows integration with tools like Jenkins or TeamCity.
• Strict coding style (enforced by AdaControl)
• Plain Ada 95 code, no Ada 2005 features used, but can be compiled as Ada 2005 or Ada 2012 code if needed
• Portable across different compilers and operating systems
• Permissive Open Source license (ISC)

• Author's blog at https://tero.stronglytyped.org/tag/ahven.html
• fedora/stable build status:
• debian/stable build status:

Ahven 2.9 compiles and passes its test suite on following platforms

Git mirrors of Ahven's Mercurial repository are available at:

• Sourcehut: https://git.sr.ht/~tkoskine/ahven
• Github: https://github.com/tkoskine/ahven

NOTE: These mirrors might be out of sync occasionally. Please use the Mercurial repository when contributing patches.

This is a minor maintenance release with updated build scripts and new source code repository location: https://hg.sr.ht/~tkoskine/ahven

As Bitbucket is shutting down Mercurial version control system support, the source code repository of Ahven has been changed to Sourcehut.

New repository address is: https://hg.sr.ht/~tkoskine/ahven

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.

This release fixes release dates mentioned in the documentation. Otherwise 2.6 is identical to 2.5.

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: https://www.ahven-framework.com/

Downloads from Sourceforge are no longer supported.

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.

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.

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.

This is a bug fix release.

The release fixes the skipped test reporting in Ahven.Text_Runner.

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.

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.

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.

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.

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.

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.

Sourceforge.net added support for Mercurial and now Ahven's source code repository is migrated from CVS to Mercurial.

This release fixes GNAT installation issues.

This is first release at SourceForge. The release includes only some build system changes.

Ahven project is now hosted by SourceForge.

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.

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.)

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.

Incremental release including bug fixes and new features.

Initial release. (See News for details.)

Ahven is distributed in source code format only. You can get the release packages from https://www.ahven-framework.com/releases/

You can download the latest development source code from Ahven's Mercurial repository: https://hg.sr.ht/~tkoskine/ahven

Git mirrors of the Mercurial repository are available at:

• Sourcehut: https://git.sr.ht/~tkoskine/ahven
• Github: https://github.com/tkoskine/ahven

The following command installs Ahven on Debian GNU/Linux 10 (buster).

sudo apt-get install libahven-doc libahven7-dev

Fedora provides Ahven as ahven and ahven-devel packages. One can install the packages with the dnf command:

sudo dnf install ahven ahven-devel libgnat-static

For building Ahven source code you need Ada 95/2005/2012 compiler, for example GNAT, Janus/Ada, Irvine ICCAda, or ObjectAda.

Optionally, you need Sphinx_ (Python package) to build the documentation and AdaControl to run coding style checks.

The default Makefile compiles code using gnatmake. Internally, gnatmake is given a GNAT project file, which works with GNAT GPL series and relatively recent FSF GNAT.

If you use another compiler, you need to customize the Makefile by yourself. Please note, that 'src' directory has platform specific subdirectories 'unix' and 'windows'. You need to select the sources from one of them also.

When using GNAT, simple make will compile the library.

Command make check will compile and run the unit tests.

If you want to build the API documentation, you need Sphinx_ tool. Command 'make docs' will build the API documentation.

Installation happens by typing make install. This installs that which has been built by earlier make commands. If nothing has been built, then make install first builds the library, just like a plain make, and then installs that. Alternatively, you can simply copy the source code directory ('src') to your project.

If you want to specify the installation directory, you need to give it during the first make via prefix variable.

make clean # not necessary for the first build
make prefix=$HOME/my-libraries/ahven
make install

Build scripts for Janus/Ada are located in the 'janusada' directory. To compile the source code, you need to first tweak file 'prepare.bat'. Then run 'prepare.bat' and 'build.bat' from the top level directory. That is the same directory where this README.md file is located.

Example:

janusada\prepare.bat
janusada\build.bat

When compilation is finished, you have tap_test.exe in the 'test_obj' directory.
