A Beginners guide to Quality Assurance

Many businesses are so keen on profits, and most of their fun talks are also mystifyingly about never-ending profits. Starting from their profound meeting halls to their delicious-looking dinner plates, it’s all about that overrated profits. Meanwhile, the media has a lot of coverage on how businesses get picky about their celebrity endorsements and marketing. But in 2021, Quality Assurance is the new vogue word taking over the tech world.

If you catch businesses talking less about their features and more about the quality and efforts, you see, that’s the shift. Quality is no longer the road not taken. In fact, it’s the only road that takes to more and more profits. This blog will teach you how to ensure top-notch quality with Quality Assurance and its very popular methods. Are you ready for the takeoff?

Importance of Quality Assurance

Wouldn’t you get frustrated or annoyed if the software you bought doesn’t work as expected or falls apart without a clue? Yes right. And would you still keep using the same software? No obviously. We live in an era where the consumer has more power over the product. It simply gets tough for the organizations once the consumer leaves with raging disappointment. And, of course, it’s worse than a nightmare to earn such a reputation of a bad quality brand.

Well, seemingly many worried consumers are getting smart and strict with the quality, and they can instantaneously set out a bad review. For the better or worse, businesses do go a time taking and none tearing rush kind of software tests. Typically these tests make sure of quality in each testing process of the software. Find the definition of Quality Assurance below.

Quality Assurance definition

Quality assurance is one of the known methods of Quality Management. It is an activity that ensures quality in every process of software/product development. A set of unskippable and conspicuous procedures to avoid problems while delivering the product to stakeholders/end-users. It quickly identifies defects in the process of product development and fixes them thoroughly to achieve a grand quality. So, what are these procedures? And how would they ensure the quality for you?

There are two types of Quality Assurance methodologies, namely non-functional and functional testing. Let’s learn the different parts of these methodologies one after the other.

1. Non-functional

These tests are run to check the readiness of non-functional aspects of the software. A few non-functional requirements of the software are reliability, performance, usability, etc. These tests can improve the efficiency, manageability, and usability of the software in the long run. And it also reduces the production risks of the concerned organization. The non-functional testing types are as follows.

  • vulnerability /security testing

This test ensures that the user data is safe and is not vulnerable to any hacking. The process safeguards the sensitive information of the user and protects it until the end of their association with the organization.

  • Compatibility testing

The software/application has to work in compliance with hardware and software. Several elements like operating systems, browsers, and plugins are tested to derive a software/application’s compliance conclusion.

  • Usability testing

A usability testing is to ensure that the software is easy to use and understandable to the end-user. Aspects like the interface, home pages, login, design, etc., are briskly tested in usability testing. The main objective of usability testing is to ensure the quick and easy use of the software.

  • Performance testing

This test is performed to learn the limitations of software performance in real-time user scenarios. The software undergoes this test in different situations, such as performance in low battery situations, a heavy traffic load, or a weak network.

  • Survivability

This test checks the comeback efficiency of the software in case of a crash or system failure. The test’s main objective is to determine if the operations of the software can be carried out even after a crash and calculating its recovery time.

2. Functional testing

Functional testing is done to test the different operational functions of the software. Suppose you have any confusion or want to know the types of functional testing in depth. Then click here to have a quick look at the different functional testing types.

The different subprocesses of functional testing are as follows.

  • Unit testing

The small chunks of the software source code are independently tested. The goal is to detach the unit functionality from the whole software and check how it individually works. Comparatively, it takes more time to conduct this type of testing as it is done in small units.

  • Integration testing

Now in this test, several units are tested to ensure their functionality as a whole. This is also one type of repetitive and time-consuming test. So, the testers mostly try to automate these tests to save time.

  • System testing

As you can see from the previous phases, the scope increases from simple code to a whole system. In this testing, different software functions are integrated and tested together to identify any unnoticed and leftover bugs in the software/application.

  • Acceptance testing

The acceptance test is not for finding and fixing bugs. It is very different from other testing types. This test is solely performed to ensure the end-user functionality of the software. It is to check if the performance is as expected from an end-user perspective? And what can be done to improve user acceptance? The major decisions of going live or not are mostly decided after this test.
