Runtime tests are executed via
make check from the
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 specifying the location of the Mauve tree when invoking
make, as in
make MAUVEDIR=~/mauve check.
The Jacks project provides a test suite for Java compilers that can be used to test changes that affect the GCJ front end. There is no automated mechanism to run the Jacks suite as part of GCJ testing.
We encourage developers to contribute test cases to Mauve and Jacks.
