E2E Test - End-to-End テスト (project)

Run comprehensive E2E tests for cargo-coupling functionality.

Test Execution

# Create test project
rm -rf /tmp/e2e-test-cargo-coupling
mkdir -p /tmp/e2e-test-cargo-coupling/src/level/enemy

# Create Cargo.toml
cat > /tmp/e2e-test-cargo-coupling/Cargo.toml << 'EOF'
[package]
name = "e2e-test-project"
version = "0.1.0"
edition = "2021"
EOF

# Create test files (lib.rs, level/mod.rs, level/projectile.rs, etc.)
# Then run tests

Test Cases

1. Nested Module Paths (Issue #14)

cargo run -- coupling /tmp/e2e-test-cargo-coupling/src 2>&1 | grep -E "level::enemy::spawner"
# Expected: Module name shows full path, not just "spawner"

2. --exclude-tests (Issue #13)

cargo run -- coupling --exclude-tests /tmp/e2e-test-cargo-coupling/src
# Expected: Test functions excluded from counts

3. JSON Output

cargo run -- coupling --json /tmp/e2e-test-cargo-coupling/src | jq .
# Expected: Valid JSON output

4. Summary Mode

cargo run -- coupling --summary /tmp/e2e-test-cargo-coupling/src
# Expected: Compact summary output

Verification Checklist

Test	Expected	Status
Nested module paths	level::enemy::spawner
lib.rs module name	lib or empty
mod.rs module name	Parent directory name
--exclude-tests	Test functions excluded
JSON output	Valid JSON
--summary	Summary only

Quick Test

# Run all unit tests first
cargo test --all-features

# Then run E2E
cargo run -- coupling ./src
