00:04:35.160 - 00:08:40.079 [INFO] [2021-06-22 18:15:35.16] [1793] [11586] - [1793] [11586] - [1793] [11586] - [1793] [11586] # ------------------------- START TEST ------------------------- python -m pytest /path/to/your/pytest/file.py ``` Here's an example of how to use pytest to test a Python script: 1. Open your terminal or command prompt. 2. Navigate to the directory where your Python script is located using `cd`. 3. Run `pip install pytest` to install the pytest package if it hasn't already been installed. 4. Create a file named `conftest.py` in the same directory as your Python script with the following contents: ```python import os def add_logs(config, log_file='results.log'): log_dir = os.path.join('logs', config['test_env']['name']) if not os.path.exists(log_dir): os.makedirs(log_dir) with open(os.path.join(log_dir, log_file), 'a') as f: f.write('------------------------- START TEST ------------------------- ') f.write(f'{config["test_env"]["name"]} - {config["test_env"]["version"]} ') f.write('------------------------- END TEST ------------------------- ') ``` 5. Open your Python script and add the following imports: ```python import pytest from config import * ``` 6. Add a test function to your script with the `@pytest.mark.test` decorator: ```python def test_my_function(): assert my_function(1, 2) == 3 ``` 7. Save and run the test using `pytest`. The output should include the logs you specified in `conftest.py`: ```yaml ============================= test session starts ============================== collected 1 item test_my_function.py .. [100%] ============================== 1 passed in 0.01s =============================== ------------------------- END TEST ------------------------- ``` 8. You can run the test again using `pytest` to see if any changes were made: ```yaml ============================= test session starts ============================== collected 1 item test_my_function.py .. [100%] ============================== 1 passed in 0.02s =============================== ------------------------- END TEST ------------------------- ``` That's it! You have now used pytest to test your Python script and log the results.
