# Sometimes we want to mark a function with an attribute.
# Define the decorator testthis which will set the
# attribute ._run_test on the function object. That
# function will then be tested. Run tests with:
#   python3 decorator_attribute.py
# or
#   python2 decorator_attribute.py

from __future__ import print_function

def testthis(func):
    ...

# This should be run as a test
def example_1():
    print('testing this')

# This should be run as a test
def example_2():
    print('testing that')

if __name__ == '__main__':
    print('running the tests')
    for name, value in dict(locals()).items():
        if getattr(value, '_run_test', False):
            print('running', name)
            value()

# To test run:
#   python3 decorator_attribute.py
# or
#   python2 decorator_attribute.py
# and check if the output contains
#   running example_1
#   running example_2
# No automatic test, sorry!

# Something like this done by
