October 26, 2022 Comment:0 Quality Assurance

In the transition to a connected society, the impact of software is a lot greater nowadays. It enhances living standards, improves the potential of businesses and creates an intelligent world. Apart from the impact on commercial or industrial operations, software is now playing a crucial function across the various walks of everyday life. All it needs is the flawless and secure operation that only software can provide.

Since the disastrous consequences of software malfunctions are destroying the human and business communities, let’s look at the reasons why software QA testing and quality control are crucial for every business.

Amazing reports about software failures

The irreparable damage that software failures can cause can be seen in the alarming news reports around the globe. In 2017, a report issued by Tricentis shows that global corporations have reported losses of 1.7 trillion in assets. It impacts 3.7 million people around the world. In 2018, across the US, software that is not of high quality is the cause of a massive cost of $2.84 trillion.

Additionally, the terrifying tales of companies that have been hit by software issues that ripped them apart are broadcast all over the world. The IT glitches that shook various business sectors, such as British Airways, Facebook, O2 network, and many others, unveiled the devastating repercussions of software malfunctions.

Let’s examine the importance of software quality assurance testing and its role in the process of software development.

What is software testing?

It’s the procedure of critical analysis in order to determine and assess whether the created application is in line with the Business Requirement Specifications. This is an ongoing process, specifically the Software Testing Lifecycle (STLC) that integrates with the development cycle of software. In each stage, it examines the app’s functionality and compares the app’s performance against the requirements.

In addition, to ensure the availability of bug-free software, software testing can help improve the functionality and accessibility of applications. There are several kinds of testing techniques for software. It is also a process that involves multiple levels of testing to confirm and validate the software.

The Importance of Software Testing

Simply put, the importance of software testing can be determined by the reaction of the user. It ensures its product’s quality and is a pleasure for customers and users. It also promises greater business efficiency (fewer maintenance costs), reliability, and an improved user experience. The efforts required to build an effective yet error-free application are numerous and vast.

However, despite the designers and developers’ testing software, the latter play an essential part in the development process. Since the development process is based on the development cycle of software, and the testing process follows with the queue to build the components to validate and verify.

It is an ongoing process of testing and validation that results in an outstanding product. Each stage of the test evaluates the effectiveness and performance of the application or system. In turn, it can be used to determine if the software programme is in line with all the requirements of the business and technical aspects.

The significance of software testing is apparent in the report on quality assurance that has been finalized. After passing the different stages of testing, the products may be able to perform better than anticipated. At every level, testers will not only find the flaws but also avoid similar issues from happening again. Additionally, the process of analysing each error can lead to the creation of an unproven version of the program.

Quality Assurance in Software Development and its Benefits

The subtle distinctions between software testing and quality assurance are too important to be overlooked. While software testing focuses upon the technological aspects of a system, quality assurance is concerned with the specifications of software. It’s a comprehensive and systematic way to assure the quality of the products that are delivered. Furthermore, the quality assurance process examines the development and testing cycles, which include methods and tools.

A quality assurance standard ensures the high quality of software components through adequate reviews of quality. The process also involves the collection of data in-process and documenting procedures. It’s a process-oriented governance programme rather than a product-focused one. It is more focused on preventive rather than restorative methods.

The quality assurance procedure monitors the development process throughout. This is why it employs a user-centric strategy to ensure quality, from the coding atelier all the way to sophisticated testing cabins. It also helps avoid bugs during the development process and oversees the entire maintenance of software.

Methods, Types, and Levels


Software applications can be checked and validated through two types of tests, which are automated and manual testing. Like the name suggests, manual testing involves conducting tests on the software by hand. It doesn’t depend on automated tools; instead, the tester compiles the programme and runs the test from the user’s viewpoint. The tester will identify bugs and mistakes manually using various levels of testing. In manual testing, testers adhere to a program, case, or scenario-based testing to finish the software test.

In the automation testing process, the tester creates scripts and relies on external software to run the tests. Products that are manually tested also undergo automated testing to ensure that the product is of good quality. This test will guarantee higher accuracy, lower costs, and also save time.


There are three ways to test software. That can be described as that they are white, black, or grey boxes.

White-box testing is also called structural testing since it is built on the structure of the source code for the application (internal). It’s unit-level tests that make sure your internal functionality of software is in line with the requirements. This way, the internal boundaries as well as the domains of data can be checked in great detail.

Black Box testing is used to evaluate the effectiveness of the program. It doesn’t care about the original code or the internal structure of the code. It is an interface-level trial-and-error software test, also known by the name input-output/data-driven test.

Grey Box testing is a proportional combination that combines White Box and Black Box tests. The tester needs both the skills and accessibility of the two other test methods to conduct this Grey Box test, i.e., the tester is granted access to databases as well as designed documents. In a hybrid model, it can provide better test scenarios within the software test procedure from the point of view of the users.


The Unit Test validates the unit component level. The tester examines every source code and then matches it to the expected result.

An Integration test is supposed to verify the connectivity between unit modules. This test helps figure out the issues that block the smooth interplay between unit components. There are a variety of ways to conduct the test, including the top-down approach, the bottom-up approach, and finally the sandwich method.

The System Test is renowned as an end-to-end test since it checks the whole software. It offers a thorough report of the performance and compliance of the system with the requirements of the business. At this stage, the entire system has been tested against the level-of-performance reports.

The Acceptance Test, also known as the Test Before Delivery, is conducted prior to the user by the testers. From an end-user perspective, the application goes through many different usability and performance tests before being handed over to the client.

Very Important Software Testing Models

The Waterfall Model: It’s an organised model for software development, which is very useful for the testing of software. As a model that is sequential, waterfall employs a specific method to conduct testing. The software will be divided into multiple phases and work on each stage as the sequence begins with Requirements-Design-Implementation-Verification-Maintenance. This way, it is impossible for any process to be overlapped or superseded by another process. It’s a straightforward engineering model that can be used to conduct software testing in a way that is easy and effective.

Iterative Development Iterative Development: In this model, every component or module will have to undergo tests repeatedly. It operates on three consecutive cycles: formulate, test, and analyze. After the repetition of each component, a new or improved model is created and then submitted for testing. Hence, with the immediate test feedback, the required changes can be made in the design, functionality, and usability with the new model.

It’s an advanced software development method that incorporates an incremental approach to testing. Since the requirements change with time, there is no other method that can provide a more flexible cycle of development or testing. The agile model addresses these problems because it is more flexible and can adapt to changing circumstances. In spite of a static-based process and tool-based approach, agile methodologies give more weight to the customer and developers.

In agile methodologies, each component is tested in real-time, which decreases the risk in the process. Because it is a method that encourages frequent interaction with customers, it takes more time and puts more stress on testers and developers.

Extreme Programming: It has an intimate connection to the Agile methodology and encourages shorter testing and development cycles. By dividing the project into multiple pieces, according to an extreme model of programming, each component will be subject to tests by the user at the time of release. This means that by incorporating the instant reaction from the customers, it is primarily for the project that is subject to frequent revisions.

It is a test-driven method that is suitable for those who don’t have a clear concept of the product.
