As a software engineer, you know that debugging is an essential part of your work. But when you have a tight deadline, you need to use the most effective and efficient debugging tools to find and fix errors in your code. In this article, we will explore some of the debugging tools that you can rely on in different situations and environments.
One of the most common and convenient debugging tools is the integrated debugger that comes with your preferred IDE (integrated development environment). An IDE debugger allows you to run your code step by step, inspect the values of variables, set breakpoints, watch expressions, and modify the code on the fly. Depending on your programming language and platform, you can use different IDE debuggers, such as Visual Studio, Eclipse, PyCharm, Xcode, or Android Studio.
IntelliJ IDEA has many different tools to help you debug. You can launch the application in local and set up breakpoints to see where potential breaks are. It has git functionality to help you compare code as well.
As a JAVA developer, I always preference is Intellij idea. You can set breakpoints, inspect variables, and step through your code.
IDE-in-built debugger tools play a crucial role in delivering a software project with a near deadline by facilitating efficient debugging. It allows developers to pinpoint and analyze issues within the codebase quickly. By stepping through code execution and inspecting variables in real-time, developers can identify and resolve bugs more effectively than manual code inspection alone. This reduces the time spent on troubleshooting and increases productivity which is important in situations where deadlines are near.
Each language has its own tool, I really like them all from Intellij :) but remember to spend time learning how to use it, the best tool is the one you know!

If you are developing web applications or websites, you will need to debug not only your backend code, but also your frontend code that runs in the browser. For this purpose, you can use the browser devtools, which are built-in tools that let you inspect the HTML, CSS, JavaScript, and network activity of your web pages. You can also use the console to execute JavaScript commands, the sources panel to set breakpoints and step through the code, and the elements panel to modify the DOM and CSS.
If you are a Web Developer you must be well versed with Browser DevTools because they help in: Element Inspector: Inspect and modify HTML/CSS. Console: Execute JavaScript, log messages, debug code. Debugger: Set breakpoints, step through JavaScript. Network Monitor: Track network requests. Performance Profiler: Analyze runtime performance. Memory Profiler: Identify memory leaks. Application Panel: Manage web app resources. Security Panel: Check webpage security. Sources Panel: Debug JavaScript and CSS. Extensions/Plugins: Add extra functionality. We tend to end up using a few of the above but it's recommended to have working knowledge of the rest as well.
With the element inspector, you can quickly identify and adjust HTML and CSS elements to address layout issues. Console logging allows for real-time tracking of variables and function calls. Network analysis capabilities help uncover performance bottlenecks and troubleshoot issues related to API calls or resource loading.
I like to use webpagetest.org for critical rendering path optimizations. In fact, DevTools is very complete and has several features, spend some time learning how to use them.

Sometimes, you may not be able to use a debugger, especially if you are working with a remote or distributed system, or if you are dealing with a complex or intermittent bug. In these cases, you can use logging tools to record and analyze the behavior and performance of your code. Logging tools can help you track the flow of execution, identify errors and exceptions, measure the time and memory consumption, and monitor the system status. Some examples of logging tools are Log4j, Logback, Winston, or Bunyan.
Logging tools allow you to track the execution path, monitor variable values, and capture error messages, providing valuable clues to identify and resolve issues efficiently. With the ability to customize log levels and filter output, you can focus on critical areas of concern and prioritize debugging.
It is very important to have well-structured logs that make sense, spend time studying OpenTelemetry and log aggregators such as DataDog, Graylog, Logz, etc.
SLF4J and Logback Log statements can provide valuable information about the flow of your application and help identify issues. Use logger.debug(), logger.info(), logger.warn(), and logger.error() statements strategically in your code.

Another way to debug your code is to use testing tools that can automatically verify the correctness and quality of your code. Testing tools can help you prevent bugs, detect regressions, improve code coverage, and refactor your code. You can use different types of testing tools, such as unit testing, integration testing, functional testing, or performance testing tools. Some examples of testing tools are JUnit, TestNG, Selenium, Jest, or Mocha.
By leveraging automated testing frameworks, such as unit tests and integration tests, you can quickly identify and rectify issues within the codebase. By running automated tests continuously throughout the development process, you can catch bugs early. Tools like Selenium, Cypress, or PHPUnit help you catch bugs before they escalate.
O Behavior-Driven Development (BDD) pode ser uma ferramenta valiosa para depurar o código de forma eficiente descrevendo o comportamento esperado do sistema em termos de cenários de usuário utilizando uma linguagem comum entre desenvolvedores, testadores e stakeholders de negócios.
