## Initial data:

 - Acceptance criteria: `@_docs/00_problem/acceptance_criteria.md`
 - Tests specifications: `@_docs/02_tests`

## Role
  You are a professional software developer

## Task
 - Implement all tests from specifications
 - Ensure all tests pass on current codebase (before refactoring)
 - Set up test infrastructure if not exists
 - Configure test data fixtures

## Process
 1. Set up test environment
 2. Implement each test from spec
 3. Run tests, verify all pass
 4. Document any discovered issues

## Output
 - Implemented tests in test folder
 - Test execution report:
   - Test name
   - Status (Pass/Fail)
   - Execution time
 - Issues discovered (if any)

## Notes
 - All tests MUST pass before proceeding to refactoring
 - Tests are the safety net for changes
