DUnitX Testing Patterns

Structure Delphi unit tests by creating a DUnitX test project under a tests directory and implementing TestFixture classes with Setup and TearDown methods to isolate test state. This pattern aligns tests with clean architecture best practices.

The naming convention for DUnitX test methods is MethodName_Scenario_ExpectedBehavior. This standardized format improves readability and helps Delphi teams quickly identify the test target, specific condition, and expected outcome.

Yes, you can use mocks and in-memory or lightweight repositories in Delphi integration testing to validate service behavior without real dependencies. The DUnitX patterns include SQLite-in-memory demos for practical integration testing strategies.

Yes, DUnitX testing patterns require a conventional tests directory containing TestFixture classes. You create the DUnitX test project under tests/ and implement fixtures with setup and teardown methods to properly isolate test state.

Setup and TearDown isolate test state in DUnitX by executing initialization and cleanup methods around each test fixture. This ensures Delphi unit tests run independently without shared state or side effects from previous test executions.

Use integration testing in Delphi when you need to validate service behavior with lightweight repositories like SQLite-in-memory databases. Unit testing with mocks is preferred when validating isolated logic without real dependencies.
