Early contact unit test

Answer 1

Creating a unit test for an "Early Contact" feature depends on the context of the application and the specific functionality you're testing. Below is a conceptual example of how to structure a unit test for a function in a hypothetical application that handles early contact requests (e.g., a customer service request form).

Example Context

Let's assume we are working with a simple system that allows users to submit early contact requests, and the relevant functionality involves validating user input, processing the request, and sending a confirmation message.

Example Code Structure

First, assume we have a ContactService class with a method submitEarlyContactRequest.

class ContactService:
    def submit_early_contact_request(self, name, email, message):
        if not self.validate_email(email):
            raise ValueError("Invalid email address")
        
        # Here we would have logic to save the request, etc.

        return "Request submitted successfully."

    def validate_email(self, email):
        # Simple email validation logic (for demonstration purposes)
        return "@" in email and "." in email

Unit Test Example

Using Python's unittest framework, here's how you might set up your unit test:

import unittest

class TestContactService(unittest.TestCase):
    
    def setUp(self):
        self.service = ContactService()

    def test_submit_early_contact_request_success(self):
        result = self.service.submit_early_contact_request(
            name="John Doe", 
            email="[email protected]", 
            message="I would like to be contacted early."
        )
        self.assertEqual(result, "Request submitted successfully.")
    
    def test_submit_early_contact_request_invalid_email(self):
        with self.assertRaises(ValueError) as context:
            self.service.submit_early_contact_request(
                name="Jane Doe", 
                email="invalid-email", 
                message="Please contact me."
            )
        self.assertEqual(str(context.exception), "Invalid email address")

    def test_submit_early_contact_request_empty_message(self):
        with self.assertRaises(ValueError):
            self.service.submit_early_contact_request(
                name="John Doe", 
                email="[email protected]", 
                message=""
            )

if __name__ == '__main__':
    unittest.main()

Explanation of the Tests

1. Test for Successful Submission:

   • It checks that a valid request returns a success message.

2. Test for Invalid Email:

   • It ensures that an invalid email raises a ValueError.

3. Test for Empty Message:

   • It checks if the method correctly handles an empty message.

Running the Tests

You can run the tests from the command line or an IDE that supports unit testing in Python. The output will show if the tests pass or fail, providing a clear indication of whether the early contact functionality is working as intended.

Enhancing the Test

You can enhance these tests with more edge cases, such as:

• Invalid name formats.
• Testing maximum lengths for name, email, and message.
• Mocking external services if the request needs to send emails or connect to a database.

This helps ensure your "Early Contact" feature is robust and ready for production use.
