Here is the list of the top 5 highly effective debugging techniques.
· Step-through debugging · Logging · Isolation testing · Binary search approach · Rubber duck debugging
Step-through debugging
Use a debugger in your IDE to execute your code line by line. This allows you to inspect the state of variables at each step, helping you identify where the code diverges from the expected behavior.
Logging
Incorporate logging with careful consideration throughout your code by embedding instructions that output the values of variables, the invocation of functions, or designated markers at various stages of execution.
Isolation testing
Break down the problem into smaller, isolated test cases. Test individual components or functions separately to identify which part of the code is causing the problem. This method lets you focus on specific areas.
Binary search approach
When handling a substantial codebase, adopt a divide-and-conquer approach. Gradually reduce the scope of the potential problem by methodically deactivating or segregating sections of the code to identify the root cause of the problem.
Rubber duck debugging
Explain your code or the problem you're facing to an inanimate object or even to a colleague who isn't familiar with the issue. The process of explaining the issue aloud frequently aids in pinpointing the underlying issue or revealing details that may have been missed.
