# LSP Testing Status (Phase 3 Complete)

## Summary
✅ **Phase 3 (LSP Server Core Features) testing complete**
- All LSP tests passing: 78/78 ✓
- All tree-sitter grammar tests passing: 27/27 ✓
- Code coverage significantly improved
- Behavior tree support fully tested in both LSP and tree-sitter

## Test Coverage

#### Behavior Tests (7 tests) - `behaviors.txt`
- ✅ Simple Behavior (single action)
- ✅ Selector Behavior (? { ... })
- ✅ Sequence Behavior (> { ... })
- ✅ Nested Behavior (selectors + sequences)
- ✅ Repeat Behavior (* { ... })
- ✅ Behavior with Subtree (@path::notation)
- ✅ Complex Nested Behavior (all node types)

#### Declaration Tests (17 tests) - `declarations.txt`
- ✅ All declaration types (use, character, template, life_arc, schedule, behavior, etc.)

#### Basic Tests (3 tests) - `basic.txt`
- ✅ Simple character, use declaration, prose block

## Coverage Improvements

**Before testing push:**
- document.rs: 80.11%
- symbols.rs: 93.04%
- diagnostics.rs: 0%
- behavior support: untested
- Total LSP tests: 34

**After testing push:**
- document.rs: 97.79% (+17.68%)
- symbols.rs: 95.24% (+2.20%)
- diagnostics.rs: fully tested
- behavior support: comprehensive test coverage
- Total LSP tests: 78 (+44 new tests, +129% increase)

## Run Commands

### LSP Tests
```bash
cd /Users/sienna/Development/storybook/storybook
cargo test --lib lsp
```

### Tree-sitter Tests
```bash
cd /Users/sienna/Development/storybook/tree-sitter-storybook
npm run test
```

**Note:** If Bash tool fails, use Serena's `execute_shell_command` instead.

## Behavior Tree Support Verified

Both LSP and tree-sitter grammar now have comprehensive behavior tree support:

### Node Types Tested:
- **action_node**: Simple action identifiers (e.g., `walk_around`)
- **selector_node**: `? { ... }` - Try options in order until one succeeds
- **sequence_node**: `> { ... }` - Execute children in sequence
- **repeat_node**: `* { ... }` - Repeat child forever
- **subtree_node**: `@path::to::tree` - Reference external behavior tree

### Syntax Examples:
```storybook
behavior SimpleBehavior {
    walk_around
}

behavior ComplexBehavior {
    ? {
        > {
            check_threat
            flee_to_safety
        }
        > {
            check_resources
            gather_resources
        }
        * {
            idle
        }
    }
}

behavior WithSubtree {
    > {
        @helpers::check_preconditions
        main_action
    }
}
```

## Next Steps (Phase 4)
