Importance Of Software Testing In Software Development Life Cycle


Software testing has become an integral element of development, and it is preferable to begin testing early in order to minimize difficulties caused by problem correction towards the end.

iByte– the best software development company; we assist our clients in improving the quality of their software by offering the best services such as software testing.

Our goal with this article is to show you how testing may enhance the overall quality of your software and the bottom line of your organization. 

Most importantly, every step of development necessitates testing, before delving into the benefits of software testing, let us first have a thorough understanding of it.

What is the Software Development Life Cycle? 

SDLC is a short form of Software Development Life Cycle, which is the process of creating an information system through appropriate analysis, design, implementation, and maintenance.

SDLC is stated to be equivalent to layer two of the Open Systems Interconnection (OSI) network communication paradigm. This level of the protocol ensures that data flows correctly from one level to the next.

 SDLC’s mode of communication consists of a primary station and a secondary station.

Phases in SDLC: 

The SDLC phases are as follows:


Gathering and Analyzing Requirements 

Information gathering and user analysis requirements are done in the first phase of SDLC.

System Design

In the next step of SDLC in which a preliminary system design is created. 


This is the phase that comes after system design and involves the development of a project.  


Testing is done to determine the actual and expected outcomes.

Maintenance and Operations

In the final phase of the SDLC process, the developed software is transferred to end-users, and if any issue comes up, or any improvement is required, it will be taken care of by the developers.

What is Software Testing?

Software Testing is an important and beneficial component in the Software Development Life Cycle in any organization.  

The purpose of Software Testing in the Software Development Life Cycle is to improve reliability, performance, and other important aspects as defined by SRS (Software Requirement Specification).

Types of Testing:

Software Testing has two categories: 

  • Functional testing 
  • Non-Functional testing.
Functional Testing

This kind of Software Testing validates the operating system in accordance with the operational standards or required specifications. Most importantly, Functional Testing is to examine various elements of the application program by delivering relevant and well-organized data to corroborate the expected outcome against the existing requirements.

Non-Functional Testing

Non-Functional Testing is used to perform the elements such as performance testing, scalability, usability, and so on.  On the other hand, the major goal of this kind is to authenticate the product’s activities by the specifications or below par.

Importance of Software Testing

Testing is important since no one is responsible for making mistakes. However, mistakes are unavoidable, but many are damaging and fatal. 

To clarify, there is a need for a thorough inspection of every software and everything made, individually or collectively, because errors occur, and they might happen when we least expect it, and we make mistakes all the time.

There’s always a nagging thought that whatever we create will have glitches. Moreover, it’s important to double-check the work we did ourselves for glitches.

All of the above, we see the need for another individual to test the developed product because they are more likely to find the glitches.

Hiring professionals with many years of experience in software testing to work on a project would be a good investment that would help your business in the long run.


Some of the most important aspects of Software Testing:
  • It lowers the amount of expenses:

The benefits of Software Testing decide to validate the software’s capabilities in several ways. Testing included in your project would prove to be cost-effective and prudent in the long run.

  • Ensures safety:

 Security is also an essential responsibility as it is the most vulnerable and possibly the most brittle aspect of software testing.

  • Guarantees the software’s peculiarity and performance:

 The software must be functioning in order to provide notable customer pleasure.

  • Provides users with a sense of fulfillment:

A developer’s primary goal would be to provide ways for users to maximize their delight when using the app’s capabilities, hence boosting user satisfaction with the product.

Certainly, to get the best results, thoroughly reviewed software and applications from the start. 

Bottom Line:

It is impossible to overestimate the importance of Software Testing.

Likewise, software testing is an important part of the software development process as it increases the consistency and performance of any software.  To sum up, the major benefit of software testing is that it identifies and eliminates errors. 

However, testing aids developers and testers to compare actual and predicted outcomes in order to improve quality.
