Reducing build/test latency
DEB_BUILD_OPTIONS="parallel=6" enables parallel build.
PARALLEL=6 enables parallel running of tests in the test suite.
DEB_BUILD_OPTIONS="no-javahl no-ruby" disables building parts that might not be relevant.
export DEB_BUILD_OPTIONS="parallel=6 no-javahl no-ruby" export PARALLEL=6 # For running tests in parallel
To isolate specific tests:
# Run a C test make -C BUILD/ check PARALLEL=6 TESTS=subversion/tests/libsvn_subr/dirent_uri-test # Run a Python test make -C BUILD/ check PARALLEL=4 TESTS=subversion/tests/cmdline/authz_tests.py
Some tests require svnserve to be available, and are skipped by default. There is a separate make target svnserveautocheck, working the same as check, that does the setup automatically to run the test suite.
Test restuls are stored in BUILD/tests.log.
Note that if one looks at tests.log in a successful build, there are about 45 tests marked as XFAIL. If you feel like a patch broke a lot of tests, compare the results against a clean build of the unpached package.
