Reminder: Please read these carefully! Students often run into directory issues
when using the provided tests that are solved by re-reading these instructions
(particularly Step 9)
1. Download tests.zip and sample_files.zip from the course website (Assignments)
2. Move both zip files to mp3/ where your three solutions are.
3. Make sure you add your mp3 folder to your VSCode Workspace (see left pane)
4. Open up a new terminal so that your path ends with mp3
5. Make sure everything looks good in your left Explorer pane and when
   running `ls` in the terminal, like so:
~/path/to/cs1/assignments/mp3$ ls
analyzer.py             tests.zip
fixer.py                mp3_starter.zip
generator.py            sample_files.zip
6. unzip tests.zip and sample_files.zip:
    - try unzip tests.zip in your terminal:
~/path/to/cs1/assignments/mp3$ unzip tests.zip
    - if that doesn't work, use your file navigator (Windows/Mac)
      to find the zip file and right-click -> unzip in the same mp3 directory
The results should look like:
~/path/to/cs1/assignments/mp3$ ls
analyzer.py             mp3_starter.zip         tests
fixer.py                sample_files            tests.zip
generator.py            sample_files.zip
7. Finally, some of your functions will assume non-nested files. To help avoid
issues in testing, copy all the contents of sample_files/ into your mp3 directory
(the below command uses * to match all files in the directory, and . means to
move to the current location, which is mp3/). You'll see a lot of files, but that's
ok for testing purposes.
~/path/to/cs1/assignments/mp3$ cp sample_files/* .
~/path/to/cs1/assignments/mp3$ ls
~/cs1/assignments/mp3$ ls
analyzer.py                     one_tab_test.txt
babbage_tabbed.txt              rooter.txt
dice_example.py                 sample_files
dice_expected.py                sample_files.zip
empty_file.txt                  spaced_four_tab_test.txt
fixer.py                        spaced_math_fns.py
four_tab_test.txt               spaced_one_tab_test.txt
generator.py                    spaced_tab0_test.txt
hamlet.txt                      spaced_tab1_test.txt
lec02_code.py                   spaced_two_tab_test.txt
lec03_fns.py                    tab0_test.txt
lec05_practice.py               tab1_test.txt
math_fns.py                     tests
montypyinterview.txt            tests.zip
mp3_starter.zip                 two_tab_test.txt

8. Finally, run the tests!
~/cs1/assignments/mp3$ pytest tests/test_analyzer.py
~/cs1/assignments/mp3$ pytest tests/test_fixer.py
~/cs1/assignments/mp3$ pytest tests/test_generator.py

9. There are two issues that students sometimes run into, depending on their machine/setup.
If you are running into errors in Step 8, try the following:

a. ~/cs1/assignments/mp3$ python3 -m pytest tests/test_analyzer.py (and so on)
b. If that doesn't work, you can move the test files in your mp3 folder with:
~/path/to/cs1/assignments/mp3$ cp tests/test*py .
similar to Step 7. If you do this, run the tests using the following (without the tests/
subdirectory):
~/cs1/assignments/mp3$ pytest test_analyzer.py
~/cs1/assignments/mp3$ pytest test_fixer.py
~/cs1/assignments/mp3$ pytest test_generator.py

c. If you are still running into test import issues, you can do the same thing as Step 7 for tests/
~/path/to/cs1/assignments/mp3$ cp tests/* (screenshot also given on Discord in lecture).
