# clone_dyn_meta Manual Testing Plan

## Overview

Since clone_dyn_meta is a procedural macro crate (compile-time code generation), manual testing focuses on verifying macro expansion correctness through integration with the parent clone_dyn facade crate. Direct functional testing of proc-macro infrastructure is not applicable - smoke tests (automated) validate crate loading.

## Testing Scope

**In Scope for Manual Testing:**
- Documentation example compilation (lib.rs lines 18-32)
- Parent crate example execution (clone_dyn_trivial.rs)
- Macro expansion verification through clone_dyn integration tests

**Out of Scope:**
- Direct proc-macro code generation testing (requires clone_dyn facade)
- Unit testing of attribute parsing (tested via integration)
- Macro implementation internals (compile-time only)

## Manual Test Procedures

### Procedure 1: Documentation Example Verification

**Purpose:** Verify documentation examples compile and demonstrate correct macro usage

**Steps:**
```bash
# Navigate to crate root
cd /home/user1/pro/lib/wip_core/wtools/dev/module/core/clone_dyn_meta

# Run documentation tests
cargo test --doc --all-features
```

**Expected Result:**
- All doc tests pass
- Zero compilation errors
- Documentation example (lib.rs lines 18-32) demonstrates:
  - Simple trait with `#[clone_dyn]` attribute
  - Trait inheritance with `#[clone_dyn]` attribute
  - Correct feature gating (`#[cfg(feature = "derive_clone_dyn")]`)

**Pass Criteria:**
- ✅ Exit code 0
- ✅ Test output shows "test result: ok"
- ✅ No warnings or errors

**Corner Cases Tested:**
- Simple trait (Trait1 with single method f1)
- Trait with supertrait (Trait2 inheriting from Trait1)
- Feature flag conditional compilation

---

### Procedure 2: Parent Crate Example Execution

**Purpose:** Verify macro generates correct code for real-world usage through clone_dyn facade crate

**Steps:**
```bash
# Navigate to parent clone_dyn crate
cd /home/user1/pro/lib/wip_core/wtools/dev/module/core/clone_dyn

# Run trivial example
cargo run --example clone_dyn_trivial --all-features
```

**Expected Result:**
- Example compiles successfully
- Example executes without panic
- Output demonstrates trait object cloning:
  ```
  1
  2
  3
  1
  2
  3
  ```
- First triplet (1,2,3) from cloned iterator
- Second triplet (1,2,3) from original iterator

**Pass Criteria:**
- ✅ Exit code 0
- ✅ Output matches expected pattern
- ✅ No runtime errors or panics
- ✅ Demonstrates CloneDyn trait functionality

**Corner Cases Tested:**
- Generic trait with lifetime parameters (IterTrait<'a, T>)
- Trait with multiple supertraits (Iterator + ExactSizeIterator + DoubleEndedIterator)
- Where clause constraints
- Trait object cloning (Box<dyn IterTrait>)
- Real-world iterator use case

---

### Procedure 3: Smoke Test Validation

**Purpose:** Verify proc-macro crate builds correctly in both local and published configurations

**Steps:**
```bash
# Navigate to clone_dyn_meta crate root
cd /home/user1/pro/lib/wip_core/wtools/dev/module/core/clone_dyn_meta

# Run smoke tests
cargo nextest run --all-features
```

**Expected Result:**
- 2 tests pass (local_smoke_test + published_smoke_test)
- Zero skipped tests
- Crate loads correctly with workspace dependencies (local)
- Crate loads correctly with published dependencies (published)

**Pass Criteria:**
- ✅ Exit code 0
- ✅ Test output shows "2 passed"
- ✅ No warnings
- ✅ Both smoke test variants pass

**Corner Cases Tested:**
- Local build configuration (workspace dependencies)
- Published build configuration (crates.io dependencies)
- Proc-macro entry point accessibility

---

### Procedure 4: Comprehensive Build Verification

**Purpose:** Verify crate builds with all feature combinations and passes all quality gates

**Steps:**
```bash
# Navigate to crate root
cd /home/user1/pro/lib/wip_core/wtools/dev/module/core/clone_dyn_meta

# Run full test suite (level 3)
w3 .test l::3
```

**Expected Result:**
- All 4 test categories pass:
  1. Local nextest (2 tests)
  2. Workspace nextest (2 tests)
  3. Doc tests (1 test)
  4. Clippy (0 warnings)
- Zero warnings in any category
- Exit code 0

**Pass Criteria:**
- ✅ Local nextest: 2 passed
- ✅ Workspace nextest: 2 passed
- ✅ Doc tests: 1 passed
- ✅ Clippy: 0 warnings
- ✅ Overall exit code: 0

**Corner Cases Tested:**
- Feature flag combinations (enabled, full)
- All compilation targets
- Documentation generation
- Linting rules

## Known Limitations

**Proc-Macro Testing Constraints:**
- Direct unit testing of macro expansion not feasible in proc-macro crates
- Functional correctness validated through clone_dyn facade crate integration tests
- Edge case coverage relies on clone_dyn test suite comprehensiveness

**Manual Verification Requirements:**
- Visual inspection of macro-generated code (via cargo expand if needed)
- Integration test execution in parent clone_dyn crate
- Documentation example compilation verification
