Test Architecture

Each test script follows a consistent pattern:

  1. Setup: Initialize clean database
  2. Test Execution: Run SQL operations
  3. Verification: Check expected results
  4. Reporting: Display pass/fail status
  5. Cleanup: Remove test databases

Test Structure

Terminal window
run_test() {
    local test_name="$1"      # Human-readable test name
    local test_num="$2"       # Test identifier (e.g., "1.1")
    local sql="$3"            # SQL to execute


    # Create fresh database
    rm -f "${TEST_DB}"*


    # Execute SQL via REPL
    output=$(timeout 10 "$BINARY" repl << EOF
$sql
\q
EOF
)


    # Verify success criteria
    if echo "$output" | grep -qE "Query OK|^\(|Column"
    then success else failure
}

Continuous Integration

All tests are designed to work in CI/CD pipelines:

#!/bin/bash
set -e  # Exit on first failure


# Build
cargo build --release


# Run tests
./run_all_tests.sh


# Report
echo "All tests passed!"

Troubleshooting

Binary Not Found

Terminal window
cargo build --release

Permission Denied

Terminal window
chmod +x test_*.sh run_all_tests.sh

Test Timeout

Tests have 10-second timeout. Increase if needed:

Terminal window
timeout 30 "$BINARY" repl << EOF

Database Lock

Remove stale database files:

Terminal window
rm -f test_*.db*
