feat(testing): add centralized test helper modules (#6)#7
Merged
Conversation
Introduces centralized helper modules for cleaner, more maintainable tests: - StubHelper: Centralized stub configuration (with_email_success, with_storage_failure, etc.) - AssertHelper: Domain-specific assertions (assert_todo_valid, assert_changeset_error, etc.) - SetupHelper: Reusable setup functions (with_todo, with_mixed_todos, etc.) All helpers are auto-imported via DataCase for seamless usage. Patterns Demonstrated: - Composable setup with named functions: setup [:with_email_success, :with_todos] - Assertion chaining: todo |> assert_todo_valid() |> assert_todo_incomplete() - Context-aware setup functions for ExUnit's setup macro Blog Post: Part 6 - Centralized Test Helpers
