#6. Run tests by doing the following (be reminded that $HOTBIT_DIR refers to /home/tlyoon/hotbit/lib64/python):

mkdir $HOME/testhotbit
cd $HOME/testhotbit
python $HOTBIT_DIR/hotbit/test/test.py

# One may run selective tests as appeared in in $HOTBIT_DIR/hotbit/test/ by issuing, e.g.,
# python $HOTBIT_DIR/hotbit/test/polyethene_twisted.py
# In case it fails to run the test, that may be due to the failure to invoke the change in $HOME/.bashrc. Log out and log in again, and then run the test again, by reissuing
#cd $HOME/testhotbit
#python $HOTBIT_DIR/hotbit/test/test.py
