Saying no to tobacco unit test

Answer 1

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.

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.

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.
