## Test Infrastructure

### Dependencies Added
```toml
[dev-dependencies]
tokio-test = "0.4"        # Async test utilities
wiremock = "0.6"          # HTTP mocking
tempfile = "3.8"          # Temporary file/directory testing
insta = "1.34"            # Snapshot testing (with JSON support)
mockall = "0.12"          # Mock generation
```

### Test Execution
```bash
# Run all tests
cargo test

# Run tests for a specific module
cargo test config::tests
cargo test api::client::tests
cargo test api::types::tests
cargo test output::tests

# Run with output
cargo test -- --nocapture

# Run with test threads
cargo test -- --test-threads=1
```

## Coverage Gaps and Future Improvements

### Areas Needing Tests
1. **Command Handlers** (`src/commands/*.rs`) - No tests yet
   - Task command logic
   - Project command logic
   - File upload/download logic
   - Error message validation

2. **API Endpoints** (`src/api/endpoints/*.rs`) - No tests yet
   - Endpoint implementations
   - Request builders
   - Response handling

3. **Main Entry Point** (`src/main.rs`) - No tests yet
   - Shell completion generation
   - Skill file generation
   - Credential validation flow

4. **Integration Tests** - Not implemented
   - Full CLI command execution
   - End-to-end workflows
   - Mock API server integration

### Recommended Next Steps

#### Phase 1: Command Handler Tests (Priority: HIGH)
- Add tests for `src/commands/task.rs`
- Add tests for `src/commands/config.rs`
- Add tests for `src/commands/file.rs`
- Mock `RepsonaClient` for isolated testing

#### Phase 2: API Endpoint Tests (Priority: MEDIUM)
- Test all endpoint request builders
- Test response parsing
- Test error scenarios

#### Phase 3: Integration Tests (Priority: MEDIUM)
- Create `tests/` directory
- Write end-to-end CLI tests
- Use wiremock for full API mocking

#### Phase 4: Coverage Tooling (Priority: LOW)
Install and configure coverage tools:
```bash
cargo install cargo-tarpaulin
cargo tarpaulin --out Html --output-dir coverage
```

## Test Quality Metrics

### Code Coverage Estimate
- **config.rs**: ~85% (14 tests)
- **api/types.rs**: ~60% (15 tests, many types covered)
- **api/client.rs**: ~80% (12 tests, core methods covered)
- **output.rs**: ~50% (14 tests, display logic covered)
- **Overall Estimate**: ~40-50% of codebase

### Test Characteristics
- ✅ Fast execution (<50ms total)
- ✅ Isolated (no external dependencies)
- ✅ Deterministic (no flaky tests)
- ✅ Clear naming conventions
- ✅ Good error messages

## Continuous Integration Recommendation

Add to CI pipeline:
```yaml
- name: Run tests
  run: cargo test --all-features

- name: Run clippy
  run: cargo clippy -- -D warnings

- name: Check formatting
  run: cargo fmt -- --check
```
