Requirements

All models

• start with Fmp
• are implemented as Java 16+ records
• implement the FmpModel interface
• have serialVersionUID
• have test: is_serializable
• have test: serializes
• use date time classes for dates, instead of strings, where appropriate
• use value objects, instead of strings, where appropriate
• have *TestData in testFixtures

All services

• use the model name + Service suffix
• are added to the appropriate FmpClient
• have tests with real responses from FMP
• with responses stored as JSON in testFixtures (for large responses, include only an excerpt)

General

• double-check your work before creating a PR
• refactor unrelated code in a separate PR from feature or bugfix changes (don’t refactor "as you go")
• adhere to the existing code style
