# Test Organization Refactoring Summary

## Changes Made

### 1. Created tests/ directory structure
- `tests/cli.rs` - CLI-level safety checks (3 tests)
- `tests/filter.rs` - SQL WHERE expression translation (6 tests)  
- `tests/integration_tests.rs` - Integration tests for the crate (1 test)
- `tests/notion.rs` - Notion API client tests with mock server (4 tests)
- `tests/output.rs` - Output rendering tests (1 test)
- `tests/schema.rs` - Schema parsing and property lookup (2 tests)
- `tests/sql.rs` - SQL statement parsing (4 tests)
- `tests/value.rs` - Value coercion tests (7 tests)

### 2. Moved 34 unit tests from source files to tests/
Tests were moved from:
- `src/cli.rs` (3 tests)
- `src/filter.rs` (6 tests)
- `src/notion.rs` (4 tests)
- `src/output.rs` (1 test)
- `src/schema.rs` (2 tests)
- `src/sql.rs` (4 tests)
- `src/value.rs` (7 tests)

### 3. Made functions public for testing
The following functions were made public (`pub fn`):
- `cli::guard_applied_full_table_mutation`
- `output::property_string`

### 4. Made Notion API error functions public
The following were made public:
- `NotionApiError::from_response`
- `find_notion_api_error` (was already public)
- `NotionClient::new_for_tests`

### 5. Removed test modules from source files
All `#[cfg(test)]` modules were removed from:
- src/cli.rs
- src/filter.rs
- src/notion.rs
- src/output.rs
- src/schema.rs
- src/sql.rs
- src/value.rs

### 6. CI/CD compatibility
The existing `.github/workflows/ci.yml` requires no changes:
- `cargo test --all-targets` automatically discovers tests in `tests/`
- `cargo build` doesn't compile test code (separate compilation)
- All existing CI commands work without modification

## Test Results
All 34 tests pass:
```
running 0 tests (lib)
running 0 tests (main)
running 3 tests (cli) - ok
running 6 tests (filter) - ok
running 1 test (integration_tests) - ok
running 4 tests (notion) - ok
running 1 test (output) - ok
running 2 tests (schema) - ok
running 4 tests (sql) - ok
running 7 tests (value) - ok
```

## Benefits
1. **Separation of concerns**: Tests are now in a dedicated directory
2. **Better organization**: Each module has its own test file
3. **Faster compilation**: Test code is compiled separately from main code
4. **Easier maintenance**: Tests follow Rust conventions
5. **Clearer structure**: Integration tests separate from unit tests

## Verification Commands
```bash
# Run all tests
cargo test --all-targets

# Build without tests (no test code compiled)
cargo build

# Run clippy
cargo clippy --all-targets --all-features -- -D warnings

# Check formatting
cargo fmt --check
```
