What are the best ways to streamline the debugging process?

2 Write unit tests

Unit tests are small pieces of code that test the functionality of a single unit of your program, such as a function, a class, or a module. Unit tests can help you verify that your code behaves as expected, and catch bugs before they cause bigger problems. Unit tests can also serve as documentation and examples for your code. You can use a testing framework, such as JUnit, pytest, or Mocha, to write and run your unit tests.

3 Use logging and tracing

Logging and tracing are techniques that allow you to record and monitor the events and data that occur during the execution of your program. Logging and tracing can help you debug issues that are hard to reproduce, or that happen in complex or distributed systems. You can use logging and tracing to track the flow of your program, the values of your variables, the performance of your functions, and the errors and exceptions that occur. Some examples of logging and tracing tools are Log4j, Fluentd, Jaeger, and Zipkin.

4 Follow coding standards

Coding standards are rules and guidelines that define how you should write and format your code. Coding standards can help you improve the readability, consistency, and maintainability of your code. Coding standards can also help you avoid common errors, such as syntax errors, naming conflicts, and logic flaws. You can use a coding standard that is widely accepted in your programming language or industry, or create your own. Some examples of coding standards are PEP 8, Google Java Style Guide, and Airbnb JavaScript Style Guide.

5 Review and refactor your code

Reviewing and refactoring your code are practices that involve examining and improving your code quality. Reviewing your code can help you spot and fix errors, as well as learn from your mistakes and feedback. You can review your code yourself, or ask a colleague or a peer to review it. Refactoring your code can help you simplify, optimize, and organize your code, as well as make it easier to test and debug. You can refactor your code by applying design patterns, principles, and best practices. Some examples of refactoring tools are ReSharper, SonarQube, and Code Climate.
