Campus-IL's self.py course is a free Python beginners massive open online course. It has a lot of exercises, many of them are "open" Python code writing tasks. These exercises are not checked by anybody or anything (except final project, and only for paid upgrade).
Students, especially as this is a beginners course, may not know how to test their solutions. It is common to only partially fulfill the exercise requirement. Having no feedback and no follow up might lead to not doing enough or doing too little.
Using Python's unittest unit testing framework, automatic tests were writen for most of the code writing exercises that have functions (Units 5-9). These tests can be used to check student's exercise solution.

There is one main test file (test_self.py) and a few auxiliary files - all files should be in the same folder.
In the above folder (with test_self.py) create a new (empty for now) file by the name: self.py
Some external modules should be installed. Though not mandatory, it enhances the tests and easy to do. In the command prompt, at the above folder, run this command:
python -m pip install -r requirements.txt
For each exercise:
- Add the functions you were asked to implement (one or more) to self.py file (exact function names mast be used).
- In the command prompt (cmd) run this command:
python test_self.py - Read tests output.
For exercise 5.3.4 (the 1st exercise checked in these automated tests), function name mast be last_early, so add your implementation of the function to self.py file:
def last_early(my_str):
# your implementation
Open command prompt (cmd) and run the tests with: python test_self.py
If all is OK, output should look something like this:
Exercise 5.3.4 (last_early): OK
----------------------------------------------------------------------
Ran 38 tests in 0.004s
OK (skipped=37)
1 exercises done successfully
32 exercises left to do
Next exercises: 5.3.5 (distance), 5.3.6 (filter_teens), 5.3.7 (chocolate_maker)
For the next exercise, 5.3.5, function name mast be distance. Add it to self.py file (after the previous function from Exercise 5.3.4):
def last_early(my_str):
# your implementation
def distance(num1, num2, num3):
# your implementation
Now run the tests with same command as before: python test_self.py
If all is OK, output should look something like this:
Exercise 5.3.4 (last_early): OK
Exercise 5.3.5 (distance): OK
----------------------------------------------------------------------
Ran 38 tests in 0.000s
OK (skipped=36)
2 exercises done successfully
31 exercises left to do
Next exercises: 5.3.6 (filter_teens), 5.3.7 (chocolate_maker), 5.4.1 (func)
If you'll have a bug in your function, a test for this exercise might fail and the output may look like this:
Exercise 5.3.4 (last_early): OK
Exercise 5.3.5 (distance): FAIL
---
True != False : Failed on: num1=4, num2=5, num3=3
