Additional Notes on Test Implementation

• Test Environment:
  • Ensure that all required JSON files (data.json and train.json) are present in the test directory (test/var).
  • Use backup directories (test/var_arv) to back up and restore original files.
• Error Handling:
  • Each test case should output clearly defined error messages that include the specific error code and a comprehensible description.
  • Use assertions to ensure that expected conditions are met. On deviations, the corresponding error codes should be triggered.
• Log Management:
  • Save relevant test results and validations in the logs to facilitate easy tracking and diagnosis.
• Automation:
  • Integrate the test class into your Continuous Integration (CI) pipeline to perform regular automated tests.
• Documentation:
  • Keep the test documentation up to date, especially when the methods of the Circuit class change or new error codes are introduced.
