What are some strategies that you can use when you debug a program?
Debugging strategies
- Incremental and bottom-up program development.
- Instrument program to log information.
- Instrument program with assertions.
- Use debuggers.
- Backtracking.
- Binary search.
- Problem simplification.
- A scientific method: form hypotheses.
How should I start debug session or code?
Once you have your launch configuration set, start your debug session with F5. Alternatively you can run your configuration through the Command Palette (Ctrl+Shift+P), by filtering on Debug: Select and Start Debugging or typing ‘debug ‘ , and selecting the configuration you want to debug.
What’s the best way to debug a problem?
Once you know where the bug is and can think of a fix, here’s a good procedure for fixing it: Write a unit test that reproduces the problem and fails. Without modifying the unit test, make it pass (by modifying application code). Keep the unit test in your test suite to prevent/detect regression. I think the reproduction of a bug is also important.
How to start debugging code in Visual Studio?
In Visual Studio, you enter debugging mode by using F5 (or the Debug > Start Debugging menu command or the Start Debugging button in the Debug Toolbar).
What does running an app within a debugger mean?
Running an app within a debugger, also called debugging mode, means that the debugger actively monitors everything that’s happening as the program runs. It also allows you to pause the app at any point to examine its state, and to then step through your code line by line to watch every detail as it happens.
How did debugging used to be a manual process?
Years ago debugging code projects was a manual process. Typically you’d be forced to simply print out data to the console and then comb through the terminal to see the output. However, with the growth of modern programming has come a nice selection of code debugging techniques that you can take advantage of.
