# get the code from my github fork:
git clone git@github.com:dweiss/lucene-solr.git --depth 1 -b junit4
cd lucene-solr/lucene

# Get a baseline for core tests running on trunk/ant macros.
git checkout trunk
ant test-core -Dtestcase=compileonly
# This is a single run and it depends on the seed, but we'll consider
# it a baseline -> write down the execution time or remember it.
ant test-core -Dtests.seed=random

# Switch over to junit4 branch and recompile.
git checkout junit4
ant test-core -Dtestcase=compileonly

# An initial pass collects statistics; these can be stored with the project to bootstrap,
# but for now they're zero. Adjust the number of CPUs to your system:
# typically, you'll want the physical number of cores - 1 (reserved for the aggregator).
# tests.seed is set to an empty value because junit4 and ltc use a different format! So there
# will be some variability across test executions (and that's good because estimates will vary).
ant test-core -Dtests.seed= -Dtests.cpus=4
ant test-core -Dtests.seed= -Dtests.cpus=4
