test.sh

#!/usr/bin/env bash
# This script runs nosetests for the whole project.
# It also generates a coverage report when the "coverage" module is installed.
# including a HTML report 

# Note: to run the tests, sage must be in your path.  If necessary do
# export PATH=$PATH:/path/to/sage
# To run it, first install or upgrade "nose", "unittest2" "coverage" and "pyflakes".
# e.g. $ pip install --user -U nose coverage unittest2 pyflakes
# or inside the Sage environment: $ easy_install -U nose
#                                 $ easy_install -U coverage
#                                 $ easy_install -U unittest2
#                                 $ easy_install -U pyflakes
# Second, call it in three ways, either
# $ ./test.sh to test all
# or
# $ ./test.sh coverage
# to test all and report test coverage
# or (for example)
# $ ./test.sh  lmfdb/knowledge
# to test only a part of LMFDB
