The task was completed in 3.5 hours with all tests passing
Goal of the exercise is to implement a tree/visitor structure that
fulfills the requirement specification provided in the unittest file
tree_test.py.
Create the initial class architecture and test it against the structure tests (remember that you can can create more classes than the strict necessary, if you think it benefits the maintanability).
Once you've done that, toggle on the functional tests by changing line 8
in tree_test.py to:
functionality_tests_off = FalseTackle the tests one by one: extend the code to pass one test, refactor your implementation for readability and expressiveness and then go on to the next test.
To run the tests, run the unittest module: python3 -m unittest tree_test.py
Common pytest options
- -v : enable verbose output
For other options, see python -m unittest -h
- Python best practices
- Completeness: did you complete the features? Are all the tests running?
- Correctness: does the functionality act in sensible, thought-out ways?
- Maintainability: is it written in a clean, maintainable way?
Please organize, design, and document your code as if it were going into production and send it back to us.
All the best and happy coding,
