The JUnit stress tests the API using a 100 MB XML file taken from the Digital Bibliography Library Project using only 256 MB of max heap space. Note: tests must be run from Maven the mvn test goal (i.e. not from the IDE) in order for patched JVM arguments to take effect via the JUte maven plugin.
Note: for proper JUnit testing, this repo should be cloned via
git lfs clone
rather than git clone. Otherwise, the XML test file will simply be a plaintext git lfs file resembling:
version https://git-lfs.github.com/spec/v1
oid sha256:2cffc115ba717045d3bf78aefaf4fdcd971878f420ff31716a1353df316277ef
size 133439113
which will then throw java.util.zip.ZipException: Not in GZIP format.
