List of Top Debugging Tools 2022

Top 10 Debugging Tools : The Only List You Need!

As we move past the stage where automation is no longer the concern, intelligence is at the front seat, being the driving force of technology in almost every space. With lines of codes that are being thought upon, strategized upon, and then implemented, viruses, and bugs, are no Bueno. 

Since the world is moving more towards online communities than physical ones, these bugs and viruses create havoc and disorient business functioning. Debugging Tools, or the debuggers are in a constant analytical environment to generate hypotheses and predict the issues with multiple test cases, that might occur in the functioning of the software. 

You will find multiple options that will suit your project or software the best, to test and debug the errors at a faster rate. In this article, we will focus on the 20 best debugging tools . But before we move ahead, let’s understand What is Online Debugging, why it is required and then focus on the debugging tools!

What is Online Debugging?

Online debugging is finding and fixing errors or bugs in a software program while real users are using it. This way, developers can quickly resolve any issues that arise without waiting for the bugs to be reported and then reproduce them in a test environment. This can include tools and methods such as monitoring, logging, and remote debugging. This is in contrast to offline debugging, where the developer needs to reproduce the error in a controlled environment before identifying and solving the problem. 

Why is Online Debugging Required?

Online debugging is needed because software programs or systems sometimes have errors or bugs that only appear when real users use them. These bugs can cause the program or plan to stop working correctly or not work at all.

When this happens, it’s essential to fix the problem quickly so the program or system can continue to be used without interruption. Online debugging allows developers to find and fix these problems as soon as they occur, instead of waiting for the bugs to be reported and reproducing them in a test environment.

Let’s see what are the steps involved in debugging.

Steps Involved in Debugging

Now that you understand, what is debugging and why it is required, here are some steps involved in the debugging process –

  1. Identifying the error – Before you proceed to debug, identify what actually the error is. The information on an error received sometimes is misleading and can take development time with 0 end result.
    Hence, it is important to identify the actual error.
  2. Error Location – Identify where the error is located. Scan the code and look for the location where the error exists.
  3. Analysis – After you have identified what the error is and where it is located, it is important to analyze the impact this error has on the program, and evaluate the details that come with it.
    Check the existing applications or programs for the bug and run automated test cases to locate if the error exists in other program aspects as well.
  4. Fix and deploy – The final stage is to fix the bug and run the automated test to see if the error is completely eradicated.
    Lastly, deploy the fix to your production servers.

To download the installer, click here.

Get started with Windows Debugging

To get started with Windows debugging, complete the following steps. To explore them in detail, go here.

  1. Identify the host and target systems
  2. Determine the debugger type: kernel mode or user mode
  3. Select the debugger environment
  4. Determine how to connect the target and host
  5. Choose either 32-bit or 64-bit debugging tools
  6. Configure symbols
  7. Configure source code
  8. Become familiar with debugger operation
  9. Become familiar with debugging techniques
  10. Use the debugger reference commands
  11. Use debugging extensions for specific technologies
  12. Learn about related Windows internals
  13. Review additional debugging resources

Debugging environments

There are six available debugging environments if your computer has Visual Studio and the WDK installed. They are namely –

  • WinDbg Preview
  • Windows Debugger (WinDbg)
  • Kernel Debugger (KD)
  • NTKD
  • Console Debugger (CDB)
  • NT Symbolic Debugger (NTSD)

For a detailed description of these environments, go to Debugging Environment.

Windows debuggers

The x86-, x64-, or Arm-based processors can run the Windows debuggers, and they can debug code that is written on those same architectures. The debugger and the code being debugged can run on the same computer in some cases, but they can also run on different computers. In both scenarios, the computer executing the debugger is referred to as the host computer, and the machine being debugged is referred to as the target computer. 

Symbols and symbol files

The Symbol files are beneficial when debugging code since they store a variety of information that is not necessary while running executable binaries. For more information, go to Symbols for Windows debugging (WinDbg, KD, CDB, NTSD).

Blue screens and crash dump files

If your windows display a blue screen and it stops working, the computer shuts down abruptly to prevent data loss and displays a bug check code. The crash dump files are analyzed with the help of WinDbg or any other windows debugging tools. 

For additional and detailed information, go to Bug Checks (Blue Screens) and Crash dump analysis using the Windows debuggers (WinDbg).

Tools and utilities

There are various tools that are helpful for debugging are included in the debugging tools for Windows.
