[FEATURE] Add Integration Tests Using WireMock

[guibranco]

Description:

To enhance the reliability of our application and ensure that the integration with the Locaweb API functions as expected, we need to implement integration tests using WireMock. This will allow us to simulate server responses without relying on the actual Locaweb API, facilitating a more controlled testing environment.

Tasks:

1. Set Up WireMock:

   • Integrate WireMock into the existing test project.
   • Configure WireMock to mock requests and responses for the Locaweb API.

2. Mock Request/Response:

   • Utilize the API SMTP Locaweb documentation to define the necessary request and response structures to mock.

3. Write Integration Tests:

   • Implement integration tests that use WireMock to simulate API interactions.
   • Ensure that the tests cover various scenarios, including success and failure cases.

4. Reference Materials:

   • Use the following resources to guide the implementation:
     • API Mocking in C# with WireMock.Net
     • WireMock.Net GitHub Repository
     • Real World Mocking HTTP Services Testing in C# Using WireMock.Net

5. Testing and Validation:

   • Run the integration tests to ensure that they work as expected.
   • Validate that the mocked responses accurately reflect the Locaweb API behavior.

6. Documentation:

   • Document the setup process and usage of WireMock in our project for future reference.

Acceptance Criteria:

• WireMock is successfully integrated into the test project.
• Mock requests and responses for the Locaweb API are correctly implemented.
• Integration tests cover a range of scenarios and pass successfully.
• Documentation is updated with instructions on using WireMock for integration testing.
