Testing and Debugging: What’s the difference? 

As we are already aware of these two terms, namely, testing and debugging. But a fundamental question arises regarding the difference between these two terms. In terms of testing, to simply define, it is a process that is performed to verify whether a software application satisfies all end-user requirements or not.  

On the other hand, debugging is the process of identifying and fixing bugs in a software application   that can affect the quality of a software system. These two processes combine to make sure that a high-quality software can be developed that satisfies all user requirements after the process of testing and debugging are finished.   

This article will help readers to understand the key differences between testing and debugging. Additionally, we’ll go through the types and methods that are employed in each of these two processes.  

What is Software Testing?

Prior to the software moving into the development phase, software testing is a process that assists both testers and developers in identifying any potential issues that can affect the quality of the software that is under development. To ensure that the software application being developed satisfies the business need, a developer or tester performs the software testing process using either manual or automated methods, which we will discuss in the next section.  

Methods of Software Testing

The process of software testing involves carrying out each test case, which covers all use cases with both positive and negative scenarios. Both manual testing and automation testing are primarily used as software testing methodologies. 

The method of manual testing of software applications involves running the test cases and comparing the outcomes to the desired behavior. As each test case is personally carried out and documented throughout the testing process, it takes additional time and effort from testers and developers. Ideally, this testing approach is difficult in bigger projects. However. in smaller projects with constrained resources and scope, manual testing is advised. 

Contrarily, automation testing is a method for automating particular manual processes. This software testing method can be carried out swiftly and properly with the help of automation tools that contributes to a decrease in overall testing time and greater increase in testing efficiency. Automation testing, to put it simply, makes the job of testers simpler and quicker. However, you should know that the basis of automation testing is manual testing, and attaining 100% automation is not quite possible.  

Process of Software Testing 

The entire software testing process can be divided into the following seven different steps:   

Step 1) Proper Requirement Analysis: By creating a thorough SRS (Software Requirement Specifications) document containing information about all test scenarios, a software tester or developer is able to understand the needs of the application. 

Step 2) Comprehensive Test Planning: To specify the objectives, available tools, and testing approach, the software tester or developer should create a thorough test plan and strategy. 

Step 3) Developing Test Cases: Upon the conclusion of step 2, the software tester or developer should have to write test cases based on the application’s requirements. 

Step 4) Test Environment Setup: In this step, the software tester or developer should have to setup the test environment with the hardware, software, and other necessary components.  

Step 5) Test Case Execution: In this step, the software tester or developer should carry out the execution of test cases via manual or automated methods, record the outcomes, and compare the actual outcomes with the expected outcomes to detect any bugs.  

Step 6) Reporting Bugs: Using some bug tracking tools, the software tester or developer finds the bugs during the test execution and follows up via creating a comprehensive bug report upon their resolution.  

Step 7) Test Closure: Finally, the software tester or developer should have to perform a final review of the test results, document the test results, and therefore end the entire software testing process.  

Benefits of Software Testing 

Following are some of the major benefits of performing software testing:  

1. Any kind of bug, error, or vulnerability in the software application can be found using the methodology of software testing. 

2. It is done to ensure that the software satisfies business requirements and performs as per the expectations of the customer or the end-user of that particular software. 

3.  It keeps track of what transpired during the testing process, which might help to prevent issues from occurring in the future. 

4. Software quality and compliance with standards and guidelines are ensured through quality assurance which is integrated with software testing. 

5. The software’s major vulnerabilities are found and mitigated through risk management during software testing process. 

What is Software Debugging? 

Determining the root cause of a bug or error in software and then repairing it is called the process of software debugging. The process of debugging is manual. Debugging tools are available for helping in the entire procedure, which will help to some extent.

It can be a challenging process since it necessitates a comprehension of the software and the fundamental concepts that underlie how it functions. As it helps to ensure that software function, it is a crucial component of software development. Although debugging might be time-consuming, it is essential for creating high-quality software solutions. 

Types of Software Debugging 

Software debugging methods can be either proactive or reactive. However, the majority of debugging is reactive; when an application failure or issue is notified, the developer works to identify the error’s root cause and fix it.  

1. Reactive Debugging: When using the reactive debugging technique, the software developer actively observes and addresses mistakes as they arise. After the code has been written and run, this happens. The developer will examine the code to see what caused the problem before making changes to it to eliminate the bug. 

2. Proactive Debugging: A technique called proactive debugging aims to identify issues before they happen. During the development phase, this occurs. Before writing the code, the software developer will employ tools and approaches to identify potential issues. The developer will then alter the code to avoid making the errors in the very first place. 

Process of Software Debugging 

The entire software debugging process can be divided into the following six different steps: 

Step 1) Identification of the bug – The software developer should first attempt to identify the bug by seeking out indications. Examine the error messages, look over the code, and analyze the findings. 

Step 2) Reproduction of the bug – The software developer should attempt to reproduce the bug after they have found it. They can reduce the number of potential bug causes by taking this step. 

Step 3) Locating the underlying issue – The software developer must identify the root cause after they’ve succeeded in reproducing the bugs. This step involves looking at the code or data to determine the root cause of the bug. 

Step 4) Fixing of the identified bug – Once the software developer has identified the root cause of bug, they can fix the bug by making the required modifications to the code or other relevant data, etc. 

Step 5) Testing of the fixed bug – The software developer must test the modification to make sure it is effective after addressing the issue at hand. Run the software and evaluate the results in this step. 

Step 6) Documentation of the fixed bug – Finally, keep a record of all the modifications the software developer made to the code so they can use for the reference in future. 

Benefits of Software Debugging 

Following are some of the major benefits of performing software debugging: 

1. Errors in coding of the software such as syntax errors, logical errors, and runtime issues can all be found using software debugging. This makes it possible for software developers to identify and address issues before they turn into visible bugs. 

2. Analyzing the software to understand how it functions and why something isn’t working is another major benefit of software debugging. A developer can learn the reasoning behind the code during the development phase and make the required adjustments to increase performance of the software. 

3. Software debugging involves testing an application’s functionality by putting it through different scenarios and observing what happens. 

4. Documentation is frequently needed during debugging so that other developers may comprehend how the software functions. 

Differences Between Software Testing and Software Debugging 

The following table summarizes the key distinctions between testing and debugging from the preceding discussion: 

Software Testing	Software Debugging
Both software testers and developers can carry out the software testing methodology.	On the other hand, software debugging is a process that only software developers can perform.
The purpose of software testing is only to identify bugs, errors, or any other vulnerability in the software.	The purpose of software debugging is not only to identify bugs in the software but also to identify their root causes in order to fix them.
Software testing can be carried out manually i.e., manual testing or using some automated tools i.e., automation testing.	On the other hand, software debugging can be carried out using two methods i.e., proactive and reactive.
Software testing is carried out after the developmental phase is completed.	On the other hand, software debugging is carried out after the testing phase is completed.

Conclusion 

In the end, to conclude this article, we can say that in order to produce high-quality software applications that satisfy user needs, testing and debugging are two essential operations that must be done out during the software development cycle.
