Finding the ideal balance between "Testing vs. Debugging" - a set of skills that makes one successful in the software development industry. Building reliable and error-free software requires having an understanding of the fundamental limitations and ambiguities between testing and debugging - these two processes are in the rapidly changing field of coding. This blog will serve as your practical road map to mastering the skill of testing and debugging, despite your level of programming experience. Let's dive in!
- What is Testing
An important step in developing reliable software is testing, which consists of thoroughly analyzing your software application to find and fix flaws. The main goal of testing is to make sure that the application works as expected, functions correctly, and satisfies all criteria. Key aspects of software testing include:
Verification of Application: It verifies that the application adheres to the design and specification.
Meets Criteria: ensures that the application satisfies the needs and requirements of its users.
Bugs Identification: Testing software seeks to find flaws, or bugs in the source code. These might be anything from syntax mistakes to logical problems that have an impact on how the application behaves.
Quality Check: Software testing is crucial as it helps with quality assurance duties. It assures that your application is user-friendly and reliable.
- Types of Testing
Throughout the software development cycle, from the Figma design to the development phases to the production phases after deployment, software testing is a constant process. It is an essential action to build scalable, reliable, and authenticated software applications. There are many different kinds of software testing techniques, each with its own set of methods and objectives.
Unit Testing: Unit testing is the most basic level of software testing, focusing on an individual's pieces of code, for example, it focuses on a specific function of your code. In this case, Developers write unit tests, which are executed regularly during the entire development process.
Integration Testing: Integration testing checks how the chunks of code interact with one another. This includes how different modules of the app communicate with one another, as well as how an application screens with other systems, for example, how the client side interacts with databases(server side).
System Testing: This includes evaluating the whole functionality of the system, as well as its reliability, and authentication of the entire system, for example, it checks that zero vulnerability of users' personal data, and overall appearance.
Functional Testing: Functional testing ensures that the application satisfies its functional requirements. The test cases are written depending on the system functionality.
Acceptance Testing: Acceptance testing assures that the application satisfies the requirements of the client. The test cases are written in accordance with the response to user requirements.
Security Testing: Security testing assures that there are no security flaws or vulnerabilities in the application. It checks that the application is not disclosing any vital information of users, or that there is not any unauthorized activity taking place in the application.
Performance Testing: Performance testing focuses on checking the software's responsiveness to various workloads. Usually, this is done to determine if the software is capable of handling the production-level load.
- What is Debugging
Finding and solving errors, or bugs, in an application, is the process of debugging. Developers must take this into consideration since bugs can make software systems decline, giving inaccurate results. Debugging is a time-consuming and challenging work. Developers construct numerous files or folders and write thousands of lines of code, so if any bug comes, it sometimes becomes very difficult to detect from exactly where the bug is coming. let's discuss some of the debugging concepts:
Identifying the Bug: Developers need to go through every possible file that is connected to that exact bug and find the file from where the bug is coming. It is one of the most important steps in debugging your application. The error can be anything, for example, syntax error, runtime error, missing files or function error, etc.
Determining what Caused the Error: Developers and testers detect the bugs, from where it is coming, and then review the code to determine what caused the error. This requires looking into the functions, classes, or code flow to find the cause of the application's unusual behavior.
Incorporate RUM: RUM - Real User Monitoring software offers continuous insight into how individuals interact with an application. This allows developers to detect and address issues with performance and helps to relieve the development pain. RUM technologies immediately capture data from users' browsers as they browse through and communicate with a website application. This information covers website load times, interactions between users, and issues.
Solving It: Developers customize the code that causes the bug to fix the issue once the error's main source has been found.
Thorough Testing: Thorough testing is performed once the bug has been fixed and makes sure it has been fixed without causing additional bugs. To ensure that existing functionality continues to perform properly, regression testing is crucial.
Debugger Tool: With the help of a debugger, you can browse through your code line by line. This can be quite useful for pinpointing the bugs' root.
Logging: Logging is used to monitor your software's performance while sending crucial data to the console. This is beneficial for debugging software applications.
- Types of Debugging
Debugging is the process of finding and resolving bugs in software programs. Developers make use of a variety of debugging methods and strategies to identify and resolve issues. Here are some of the key debugging techniques:
Reactive Debugging: Once the developers find the bugs, they fix them, this is known as reactive debugging. This form of debugging is the most typical and is often carried out when a software system violates or exhibits unexpected behavior.
Interactive Debugging: The most popular type of debugging is interactive debugging, in which coders rely on debugging tools to create breakpoints, analyze every variable, and line by line execute the code in their code editor.
Console Debugging: In order to gather information about what your code is interpreting and the execution flow of your code, printing or consoling of your code is crucial. You will get a thorough idea of what your code is doing, and what makes the unusual bug in the application. It's straightforward, yet it works effectively for rapid troubleshooting.
Remote Debugger: Developers can remotely debug code that is running on a server or any remote environment. Remote Debugger becomes very helpful when it is installed on remote hardware.
Manual Code Review: Manual code reviews involve letting developers analyze other developers' written code to find problems like logical mistakes, and coding errors.
- Testing vs debugging:
Testing vs Debugging are two independent but connected stages in the software development process. The testing process involves ensuring that a software system meets its functional and non-functional requirements. Bugs or other problems in the software system are discovered and resolved through the process of debugging.
