Key Patterns in This Script

• Background process (& and $!): Start the server in the background and capture its PID
• Health check loop: Wait for the server to be ready before running tests
• Exit code capture ($?): Save the test exit code before running cleanup
• Cleanup on exit: Kill the server regardless of test outcome
• Graceful error handling: kill $PID 2>/dev/null || true does not fail if the process is already dead
