"""Test script to check for required functionality.
Execute this code at the command line by typing:
python swc-installation-test-2.py
Run the script and follow the instructions it prints at the end.
This script requires at least Python 2.6. You can check the version
of Python that you have installed with 'swc-installation-test-1.py'.
By default, this script will test for all the dependencies your
instructor thinks you need. If you want to test for a different set
of packages, you can list them on the command line. For example:
python swc-installation-test-2.py git virtual-editor
This is useful if the original test told you to install a more recent
version of a particular dependency, and you just want to re-test that
dependency.
"""
# Some details about the implementation:
# The dependencies are divided into a hierarchy of classes rooted on
# Dependency class. You can refer to the code to see which package
# comes under which type of dependency.
# The CHECKER dictionary stores information about all the dependencies
# and CHECKS stores list of the dependencies which are to be checked in
# the current workshop.
# In the "__name__ == '__main__'" block, we launch all the checks with
# check() function, which prints information about the tests as they run
# and details about the failures after the tests complete. In case of
# failure, the functions print_system_info() and print_suggestions()
# are called after this, where the former prints information about the
# user's system for debugging purposes while the latter prints some
# suggestions to follow.
