Unit tests

[Aleksandergreg]

User Story

As a Ruby developer,
I want to implement unit tests using a standard Ruby testing framework,
so that we can catch errors early and validate small components in isolation.

---

Acceptance Criteria

• A Ruby testing framework like RSpec or Minitest is installed and configured.
• At least a few unit tests are written for critical methods or logic.
• Unit tests are runnable locally by all team members.
• Unit tests are included in the CI pipeline (kinda already done, but I am a bit in doubt if it is integration or unit).
• The team has discussed and documented which types of tests were skipped and why.

---

Tasks

• Choose a unit testing gem: RSpec (recommended) or Minitest.
• Add the chosen gem to your Gemfile:
  • For RSpec: gem 'rspec'
  • For Minitest: gem 'minitest'
• Set up the test environment using rspec --init or appropriate configuration.
• Write at least 2–3 unit tests for application logic (e.g., services, helpers).
• Run unit tests locally to ensure correctness.
• Optionally, integrate unit tests into your CI/CD pipeline.
• Document your testing decisions (why some components were tested and others not).

Additional Context / Notes (Optional)

• For RSpec setup: https://rspec.info/documentation/
• Minitest is built into Ruby, but RSpec has a more expressive DSL and community support.
• Unit testing isn't required but shows depth in test strategy.
