Saying no to tobacco unit test

Creating a unit test for a program related to "saying no to tobacco" could involve various aspects, such as verifying that the system correctly processes data related to tobacco cessation, tracks user activities, or provides appropriate responses or resources. Below, I'll outline a simple example of how you might structure such a unit test in Python using the `unittest` framework. This example will be hypothetical and will implement a function that determines whether a user is successfully quitting tobacco.
### Sample Code
Let's assume we have a simple `TobaccoCessation` class with a method `is_quitting_successful` that checks if a user has not smoked for a certain number of days.
```python
class TobaccoCessation:
def __init__(self):
self.smoking_days = 0
def record_day(self, smoked: bool):
if smoked:
self.smoking_days += 1
else:
self.smoking_days = 0
def is_quitting_successful(self, threshold_days: int) -> bool:
return self.smoking_days == 0 and threshold_days > 0
```
### Unit Test
Now, we will write unit tests for this class to ensure that it behaves as expected.
```python
import unittest
class TestTobaccoCessation(unittest.TestCase):
def setUp(self):
"""Set up a new TobaccoCessation instance for each test."""
self.cessation = TobaccoCessation()
def test_quitting_successful_after_zero_days(self):
"""Test that quitting is successful when no days of smoking recorded."""
self.cessation.record_day(smoked=False)
self.assertTrue(self.cessation.is_quitting_successful(threshold_days=7))
def test_quitting_failed_after_smoking(self):
"""Test that quitting is not successful if there are smoking days."""
self.cessation.record_day(smoked=True) # User smokes
self.assertFalse(self.cessation.is_quitting_successful(threshold_days=7))
def test_quitting_successful_with_days_threshold_met(self):
"""Test that quitting is successful with sufficient threshold days if no smoking occurred."""
self.cessation.record_day(smoked=False) # User does not smoke
self.assertTrue(self.cessation.is_quitting_successful(threshold_days=1))
def test_quitting_failed_when_threshold_is_zero(self):
"""Test that quitting is not considered successful when threshold is zero."""
self.cessation.record_day(smoked=False) # User does not smoke
self.assertFalse(self.cessation.is_quitting_successful(threshold_days=0))
if __name__ == '__main__':
unittest.main()
```
### Explanation
1. **Class Definition**: The `TobaccoCessation` class contains methods to record smoking days and check quitting success based on those records.
2. **Unit Test Structure**: The `TestTobaccoCessation` class uses the `unittest` framework to define a series of tests for the `TobaccoCessation` class:
- `setUp`: Prepares a fresh instance of `TobaccoCessation` before each test.
- Various test methods check different scenarios, such as successfully quitting, failing due to smoking, and appropriately handling threshold days.
3. **Running the Tests**: When you run this script, the unit tests will execute, validating that the `TobaccoCessation` class behaves as expected in various scenarios.
### Conclusion
This example demonstrates how you can create unit tests for a specific feature in a tobacco cessation application. Modify it according to your actual business logic and application requirements.
