From Maven:
Run cross-language tests from the installed project:

mvn clean test -Pcheck_cpp_files -Dtest.data.root="..."
#  test.data.root is never required under Maven 
# (it defaults to project.basedir), but a user running via Maven 
# can still choose to set -Dtest.data.root=... 
# if they want CL test data read from/written to somewhere other 
# than the installed project directory. 
# It's only strictly mandatory when running the packaged jar 
# standalone via java, since there's no pom default to fall back on there.


From Java:
Run all tests from the test.jar. 
First build the classpath:

CP=""
CP="${CP}datasketches-java-9.1.0-tests.jar:"
CP="${CP}datasketches-java-9.1.0.jar:"
CP="${CP}testng-7.12.0.jar:"
CP="${CP}jcommander-1.83.jar:"
CP="${CP}slf4j-api-2.0.16.jar"
CP="${CP}slf4j-simple-2.0.16.jar"
CP="${CP}jquery-3.7.1.jar"
CP="${CP}guice-5.1.0.jar" #optional
CP="${CP}snakeyaml-2.6.jar" #optional

java -Dtest.data.root="/" \
     -cp "$CP" \
     org.testng.TestNG testng.xml -testnames "Run_All_Java_Tests"

On Windows use back-tic "`" for line continuation and ";" for classpath separation.
