What is Debugging?

Debugging is a critical process in software development, involving identifying, analyzing, and resolving bugs or errors in code. It ensures software functions correctly and efficiently, often using specialized tools for error detection and fixing.

What is Online Debugging?

Online debugging is a unique feature that enables developers and testers to assess and troubleshoot specific components using various web browsers in real-time. It allows testers to thoroughly examine and evaluate crucial components online, using different combinations of web browsers.

The web landscape is highly fragmented into various device-browser combinations where every browser contains its most recent and older versions, increasing complexity.

Creating web applications that offer a quality user experience on all devices will be a big task for developers or teams.

This problem can be solved by developers or teams using a real device cloud that is hosted by any cloud-based testing platform. Developers that use cloud-based platforms for testing also have access to DevTools to examine particular web page elements on real devices. Debugging HTML, CSS, and JavaScript on the target devices is now easy and practical.

Why is Online Debugging Required?

Software developers and testers use debugging methods to find and correct program bugs before making them available to the users. It’s another step to testing, which entails discovering how a mistake affects a program. Here are some benefits of using online debugging for any application or website:

• Streamlines the software development process, meaning you produce high-quality products for your customers.
• It helps to identify potential issues and errors immediately so that these can be fixed before the changes are pushed to the production environment.
• It helps to understand and evaluate the overall quality of the built systems.
• It allows different teams to identify areas that need improvements. The modules or functionalities that had issues can be tested more thoroughly.
• It ensures that the quality of the application or website remains great from a delivery perspective.

Steps Involved in Debugging

Determining and addressing code bugs is a crucial step in creating debugging software. It involves finding the error, identifying the fault location, analyzing it, and fixing it. These procedures let programmers fix issues and raise the caliber of their software. When you undertake debugging, the following steps are necessary:

1. Finding the error: It is essential because doing so will help you save time and effort.
2. Identify the fault Location: After the fault has been detected, you must assess the precise location of the error.
3. Analyze the Error: After pinpointing the error’s precise position, you should take some time to consider the error’s specifics. You can verify the currently running program or webpage to determine if the problem will not affect the system’s functionality.
4. Fix and Validate: The last step is correcting mistakes and checking the system’s functionality.
