Use `private const` when elements are exclusive to a class, or, if shared, a `XxxxConsts` class with `internal const` members and reduced visibility. - When possible, components should use a fluent style for construction/configuration. - Methods must have clearly bounded responsibilities; actions should be focused and the code readable, split into small chunks (ideally no more than 50 lines of code). ## Tests - Reusable, associated fixtures must be used, with methods that create common elements for multiple tests, reducing complexity and improving readability. - Tests must be unit tests, using mocks or WireMock (for endpoints). - Interfaces of the elements under test must be used, for example: `IWorkflowExecutor executor = new WorkflowExecutor()`, ensuring that the interface is fully implemented and complete. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/pinedatec-eu) — claim your Tome and manage your conversions.
