Add Tests

[nimir]

Description

We need to add test coverage to ensure reliability and stability.
Let's start with simple tests coverage to verify main API interactions.

Following the approach used in ruby-openai, we can use recorded API responses as fixtures using VCR.

Test Dependencies

We will use the following gems:
• RSpec – for writing and running tests
• VCR – for recording and replaying API responses
• WebMock – for intercepting and mocking HTTP requests

Tasks
• Set up RSpec as the test framework.
• Integrate VCR to record and replay API responses.
• Use WebMock to stub HTTP requests.
• Write tests for core functionalities of the gem.
• Ensure tests cover various edge cases and expected failures.
• Add a simple GitHub Actions workflow for automated testing (Bonus).

Expected Outcome
• A well-tested codebase with clear coverage.
• Confidence in making future changes without breaking functionality.
• Easy-to-run test suite for contributors.

Note

I plan to add this when I can, but it might not be very soon. Would love contributions!
