Code coverage is a measurement of how much of your code has been executed during testing and can help identify areas of your program that may need additional testing. To do code coverage in Python, you can use a tool called `coverage.py`. Here are the basic steps:
1. Install `coverage` using pip: `pip install coverage`.
2. Navigate to the directory containing your Python code.
3. Run your test suite with coverage using the command `coverage run -m unittest discover`. This will run all of your tests and record which lines of code were executed.
4. Generate a coverage report using the command `coverage report`. This will show you the percentage of lines of code that were executed during testing.
You can also generate an HTML report by running `coverage html`, which will create an HTML report showing which lines of code were executed and which were not. This can be helpful for identifying areas of your code that are not being properly tested.
Overall, using `coverage.py` is a great way to ensure that your code is well tested and that you are not missing any important areas of your program.
