Runtime tests are executed via make check from the testsuite
directory of the libjava hierarchy in the build tree. Additional runtime
tests can be checked into this testsuite.
Regression testing of the core packages in libgcj is also covered by the
Mauve test suite. The Mauve Project
develops tests for the Java Class Libraries. These tests are run as part
of libgcj testing by placing the Mauve tree within the libjava testsuite
sources at libjava/testsuite/libjava.mauve/mauve, or by specifying
the location of that tree when invoking make, as in
make MAUVEDIR=~/mauve check.
To detect regressions, a mechanism in mauve.exp compares the
failures for a test run against the list of expected failures in
libjava/testsuite/libjava.mauve/xfails from the source hierarchy.
Update this file when adding new failing tests to Mauve, or when fixing
bugs in libgcj that had caused Mauve test failures.
The Jacks project provides a test suite for Java compilers that can be used
to test changes that affect the GCJ front end. This test suite is run as
part of Java testing by placing the Jacks tree within the the libjava
testsuite sources at libjava/testsuite/libjava.jacks/jacks.
We encourage developers to contribute test cases to Mauve and Jacks.
