The Ada testsuite includes executable tests from the ACATS testsuite, publicly available at http://www.ada-auth.org/acats.html.
These tests are integrated in the GCC testsuite in the
ada/acats directory, and
enabled automatically when running make check, assuming
the Ada language has been enabled when configuring GCC.
You can also run the Ada testsuite independently, using
make check-ada, or run a subset of the tests by specifying which
chapter to run, e.g.:
$ make check-ada CHAPTERS="c3 c9"
The tests are organized by directory, each directory corresponding to a chapter of the Ada Reference Manual. So for example, c9 corresponds to chapter 9, which deals with tasking features of the language.
There is also an extra chapter called gcc containing a template for creating new executable tests, although this is deprecated in favor of the gnat.dg testsuite.
The tests are run using two sh scripts: run_acats and run_all.sh. To run the tests using a simulator or a cross target, see the small customization section at the top of run_all.sh.
These tests are run using the build tree: they can be run without doing
a make install.
