//! # Test Module Structure and Coverage Outline
//!
//! This module aggregates various test suites for the `former` crate and its associated derive macros.
//! Below is an outline of the features tested and their corresponding test modules within this directory.
//!
//! ## Feature Coverage Outline:
//!
//! - **Former Derive for Structs**
//!   - **Basic Functionality:**
//!     - Simple struct definition and forming
//!     - Primitive types
//!     - Optional types
//!     - Tuple structs
//!     - User-defined types (with Default, without Default, without Debug)
//!     - Unsigned primitive types
//!   - **Collections Handling:**
//!     - Basic scalar setters for collections
//!     - Standard collections (Vec, `HashMap`, `HashSet`, `BTreeMap`, `BTreeSet`, `LinkedList`, `BinaryHeap`)
//!     - Collection interface traits
//!   - **Subform Setters:**
//!     - `#[ subform_collection ]` (implicit, explicit definition, named, custom, setter on/off)
//!     - `#[ subform_entry ]` (implicit, manual, named, setter on/off, `HashMap` specific)
//!     - `#[ subform_scalar ]` (implicit, manual, named)
//!     - Combinations of subform attributes on a single field
//!   - **Attributes:**
//!     - **Struct-level:**
//!       - `#[ storage_fields ]`
//!       - `#[ mutator( custom ) ]`
//!       - `#[ perform ]`
//!     - **Field-level:**
//!       - `#[ former( default = ... ) ]`
//!       - `#[ scalar( name = ..., setter = ..., debug ) ]`
//!       - `#[ subform_collection( name = ..., setter = ..., debug, definition = ... ) ]`
//!       - `#[ subform_entry( name = ..., setter = ..., debug ) ]`
//!       - `#[ subform_scalar( name = ..., setter = ..., debug ) ]`
//!       - Multiple attributes on one field
//!       - Feature-gated fields (`#[ cfg( ... ) ]`)
//!   - **Generics & Lifetimes:**
//!     - Parametrized struct
//!     - Parametrized field
//!     - Slice lifetimes
//!     - Dyn traits
//!   - **Edge Cases:**
//!     - Keyword identifiers for fields
//!     - Keyword identifiers for subform setters
//!     - Name collisions (with std types, keywords, etc.)
//!     - Visibility (public/private structs and fields)
//!   - **Compile-time Failures:** Tests ensuring incorrect usage results in compile errors.
