Testing Vs Debugging: The Differences You Need to Know!

We know about Testing and Debugging. But what is the difference between these two processes? Why are these two processes essential for software development? In this article, we will find answers to all these questions. You will learn about the features, the tools used in each process, and the types.

Did you know Testing and debugging are two essential processes in software development?

  • Testing is a process that confirms a program or system meets all its specifications.
  • Debugging is finding and fixing errors in a program or system.

The two processes work together to produce a high quality product that meets the user’s needs. For a Tester, Sound business knowledge is an added advantage in this field of work. A developer who knows the software application design and the code does the Debugging. However, a developer who debugs should have both technical and business knowledge. On completing Testing and Debugging, we can ensure a quality product is ready for the customer.

What is Testing?

Testing is a process that helps you discover possible issues before the application moves to production (i.e., the application goes live). A developer or a tester does the Testing process through any method -Automation or Manual. Testing involves evaluating a system’s components to determine whether it satisfies the specified requirements. It is a process of ensuring that the application software meets the business requirement.

Testing involves the execution of each test case, which covers all the use cases with positive and negative scenarios. The two testing methods are Manual Testing and Automation Testing.

Manual Testing is a process of testing software applications manually by executing the test cases and validating the results against the expected behavior. This testing requires more effort from testers as they manually execute every test case and document each step taken during the process. Now you can see this is a challenging testing method. It is advisable to use manual testing for small projects with limited scope and resources.

Automation Testing, on the other hand, is a process of automating specific manual processes. There are automation tools to execute tests quickly and accurately with minimal manual intervention. This helps reduce the time required for testing and increases the overall efficiency of the testing process. In simple words, Automation Testing makes your work easy and quick!

In this next section, we will discuss the features of Testing.

  • Continuous Integration: It integrates code changes. This process helps to find, address and rectify bugs.

  • Invest in Test Research: Test research analyzes test results to find improvement areas.

What is Debugging?

Debugging is finding bugs or errors in code, determining their cause, and then fixing them. Debugging is a manual process. There are helping tools to debug, which will narrow down the process to an extent.

Debugging can be complex, as it requires understanding the code and underlying principles that govern its performance. It is an integral part of software development, as it helps ensure that programs function. Debugging can take considerable time, but it is a must for producing high-quality software products.

Various methods of debugging code include:

  • Using breakpoints to halt execution at fixed points in the program, like analyzing variables and their values.

  • Tracking program flow.

  • Examining memory contents and simulating possible inputs to detect strange behavior.

Hence, Debugging involves testing various versions of the code to discover the best version of it.

Features of Debugging

As we know, debugging is finding and eliminating program errors. It can be done manually or with specialized tools. Here are some of the features of debugging:

  1. Error Detection: Debugging helps to detect errors in a code, such as syntax errors, logical errors, and runtime errors. This allows developers to find and fix problems quickly before they become notable bugs.

  2. Code Study: Debugging also involves examining code to determine how it works and why it is not working. During the process, a developer can understand the logic behind their code and make necessary changes to improve its performance.

  3. Testing: Debugging encloses testing as a program’s functionality by running it through various scenarios and observing its behavior.

  4. Performance Optimization: Debugging can be employed to find and address inefficient bottlenecks or code, aiming to optimize a program’s performance. Such optimization may result in increased speed or efficiency.

  5. Documentation: Debugging often requires documentation so that other developers can understand how the program works.

Types of Debugging

There are two types of Debugging techniques: Reactive and Proactive. Most debugging is Reactive—a defect is reported in the application, or an error occurs, and the developer tries to find the root cause of the error to fix it.

Reactive Debugging: Reactive Debugging is a technique where the programmer actively monitors and responds to errors as they occur. This occurs after the code has been written and executed. The programmer will explore the code to find the cause of the error and then make changes to the code to fix the bug.

Proactive Debugging: Proactive Debugging is a technique that focuses on finding errors before they occur. This happens during the development process. Here the programmer will use tools and techniques to find possible problems before writing the code. The programmer will then make changes to the code to prevent the errors from occurring in the first place.

What are the steps of Debugging?

The following steps are followed to conduct a proper debugging process:

  1. Find the bug: First, try to discover the bug by looking for clues. Check the error messages, read through the code, and look at the output.

  2. Reproduce the bug: Once you have recognized the bug, try to reproduce it. This step will help you narrow down the possible causes of the bug.

  3. Isolate the cause: Once you have reproduced the bugs, you must isolate the cause. This step means looking at the code or data to find out what is causing the bug.

  4. Fix the bug: Once you have identified and isolated the cause, you can fix the bug by doing the necessary code or data changes, etc.

  5. Test the fix: After fixing the bug, you must test it to ensure the change works. This step involves running the code and checking the output.

  6. Document the fix: Finally, document all the changes you made to fix the code so you can refer to it in the future.

How to Optimize Debugging Process

To optimize the debugging process, you can use several strategies:

  1. Ensure that you have all of the necessary information: Before beginning the Debugging process, ensure you have all the required information available. This process includes the code you are attempting to debug, logs, error messages, and other relevant data. This information will help you quickly see and resolve the bug.

  2. Reproduce the bug: Try to reproduce the bug in a controlled environment. This process will allow you to isolate the issue and better understand what is causing it.

  3. Break down the bug: Break down the bug into smaller, manageable parts. This process is effortless to find the root cause so that you can find a solution.

  4. Verify assumptions: This process helps to end potential sources of errors and can help narrow down the issue.

  5. Use Debugging tools: Debugging tools such as debuggers, profilers, and loggers can be helpful when trying to specify and fix bugs. Take advantage of these tools when debugging your code.

  6. Ask for help: To resolve the bug, you can also check online resources, as many sites are available to help.

  7. Document the Debugging process: It is a great way to ensure you remember all the essential steps.

  1. Test Plan: A test plan is a document that outlines the strategy, scope, approach, resources, and schedule of intended testing activities. The testing team uses it to plan, coordinate, and manage the testing activities for a particular project.

  2. Analysis: Analysis is breaking down a problem into its parts to be better understood and solved. It involves gathering information, identifying relevant factors, and forming conclusions.

  3. Design: Design is creating a plan or blueprint for a product or system. This involves defining the architecture, components, interfaces, and other aspects of the product or system.

  4. Development: Development is turning a design into a working system or product. This involves coding, testing, and debugging the system or product.

  5. Execution: Execution is the process of running a program or system. This involves creating and running the necessary procedures and tasks to get the system running.

  6. Bug Fixing: Bug fixing is fixing errors in a system or program. This involves identifying and resolving errors in the code and testing to ensure that the mistakes have been corrected.

  7. Software Implementation: Software implementation is putting a software product into operation. This involves installing the software, configuring it, and ensuring it runs properly.

What are the 4 levels of testing?

The four levels of testing are:

  1. Unit Testing: This is a method in which individual units or components of a program are tested to determine if they fit for use. Unit tests are implemented to ensure that each software unit operates as planned. The developers perform this testing while the development process is underway.

  2. Integration Testing: This level of testing is used to test different units or components within a system to ensure they are integrated appropriately.

  3. System Testing: This testing level ensures that an entire system works as intended. A Quality Assurance team typically does it to ensure the design meets all required functionality.

  4. Acceptance Testing: The final phase of testing, also referred to as user acceptance testing (UAT), is designed to ensure that the system works for the end user. The customer or end user conducts this part of testing to assess the system’s overall usability and performance.

What are the stages of debugging?

The stages of debugging involve the following steps:

  1. Identify the Problem: Before you begin the debugging process, you must identify the problem. This can involve examining error messages, observing unexpected behaviors, or researching potential conflicts with other software or hardware.

  2. Reproduce the Problem: Once you have identified the problem, you need to be able to reproduce it consistently. This often requires narrowing down what causes the problem and finding a consistent way to make the problem happen.

  3. Isolate the Cause: After you have identified and reproduced the problem, you must try to isolate the source of the problem. This can involve examining the code, running diagnostic tests, or using a debugger to trace the flow of the program.

  4. Evaluate Possible Solutions: Once you have isolated the cause, you can evaluate possible solutions. This might involve trying different approaches, changing the code, or looking for other sources of information that can help you solve the problem.

  5. Test and Implement Solution: If you have identified a possible solution, you must test it to confirm it works. Once the solution works, you can execute it.

  6. Document the Process: Once you have solved the problem, you should document the process you went through to solve it. This can help you diagnose similar issues more quickly in the future and also serve as a reference for others who may have the same problem.
