Debugging and Testing

Debugging and testing are critical steps in the software development process. Debugging involves the process of finding and fixing errors or bugs in your code, while testing is the process of verifying that your code functions as intended.

When it comes to debugging, experienced engineers employ various techniques to identify and resolve issues efficiently. These techniques can include:

• Print Statements: Adding print statements throughout the code to check the values of variables and track the flow of execution.
• Step-By-Step Execution: Using a debugger to execute the code line by line, observing the values of variables at each step.
• Logging: Writing detailed logs during program execution to gather information about the program's behavior.
• Code Review: Seeking assistance from peers or conducting a thorough code review to identify logical errors or potential issues.

Testing ensures that your code produces the expected output for a variety of inputs. It involves creating test cases to validate the correctness and functionality of your code. Common testing techniques include:

• Unit Testing: Testing individual units of code, such as functions or classes, to ensure they work correctly in isolation.
• Integration Testing: Testing the interaction between multiple components or modules to ensure they integrate smoothly.
• Regression Testing: Re-running previously successful test cases to ensure that new changes haven't introduced unintended side effects.

By incorporating effective debugging and testing practices into your development workflow, you can significantly improve the quality and reliability of your code.
