Debugging

Debugging is the process of detecting, isolating, and fixing errors (bugs) in the code. This involves systematically testing where and why a business application exhibits unexpected behavior, using tools such as debuggers, logging, and monitoring. Efficient error detection speeds up the development process and helps ensure business continuity in critical systems.

• Google Chrome DevTools - for debugging web applications
• Application Performance Monitoring tools - for identifying issues in production systems

Key Points

• You use a systematic problem-solving approach: forming hypotheses about the bug cause, performing targeted testing to confirm or refute these, and thus isolating and solving the root cause. Additionally, after fixing, you verify that the bug is actually resolved and doesn't have unintended consequences elsewhere in the system.
• You effectively use debugging tools: set breakpoints, inspect variables during runtime, analyze logs, and step through the code to determine the cause of errors in business applications.
• You can communicate technical issues in business-friendly language to stakeholders when needed.
