Importance of Quality Assurance in Software

Nov 05, 2014 by Petr Kudlacek | Post a Comment

Quality assurance (QA) is such an important aspect of the production of any software. It can eliminate problems before software launch. We want to share with you the ways in which investing in proper QA can help to develop better software. Through more effective processes, software development is streamlined to provide you with the best possible product.


Identifying the Need for QA


Have you ever encountered software that seems as if it was pushed right out the door? We all have and it can be upsetting as well as disastrous for any software development team. No one wants to keep buying software that doesn't do what promises. QA methods have been designed to eliminate any issues prior to launch.



Do you know which form of quality assurance is right for you? Are you not even sure if you need it? I promise you that you need to have quality assurance built into the way you produce software. If not, you will end up with software that is not valuable to you or the user. Taking the time to go through the process of QA helps to assure that the end product will be helpful and provide value to the user. In short, you will not be embarrassed when launching the software.


What You Need to Learn About QA


There are three areas to QA that are important to understand. These are:

  • The QA process
  • Types of QA
  • Examples of QA

These will help you understand the fundamentals of quality assurance and why it's vital to software development.


The Process


The method of software testing assures proper QA for software. It is necessary to go through a consistent model of software development using teams reporting in daily about progress and development. Constant testing of the software during development streamlines the process of creating a better overall product. This manner of testing fits in with the agile methodology as well as the automated test life-cycle methodology. In both cases, the methods are focused on testing the software in sections rather than as a whole to find problems as they arise.


The individual processes that are involved in the testing include requirements definition, in which the overall system requirements for the software are indicated. This indication provides the structure by which the software goes from a thought to an actual working product. The process includes:


 testing process


  • Coding - the individual actions of the software are written out
  • Source code control - the information about the type of code used is provided
  • Code reviews - the code is reviewed to find any errors that may have cropped up; also known as debugging
  • Change management - the process of making changes to the software as it is being developed without slowing down the launch date
  • Configuration management - assures the software will fit in with the requirements definition as well as with the other software that it needs to work with
  • Testing - makes sure that the software actually does what it is intended to do
  • Release management - eases the software from production into release mode
  • Product integration - assures that the software is ready to be used by the user.

These processes may not show the entire picture, but they are all a part of the process. They are needed to make sure that at any given time the possible problems the software might encounter are being discovered and fixed.


Types of QA

 software testing types


When it comes to testing for QA, there are three main types. These include:

-       Functional testing - black box and white box

-       Automated testing

-       Performance testing

Performing these tests allows you to learn more about the software, issues and challenges, and provides the essence by which solutions can be provided.


Functional Testing


There are two types of functional testing – black box and white box. Black box tests the software to make sure that it meets customer requirements. This can include that the software operates properly under certain parameters and that the customer will achieve the desired results while using the software. This testing shows how the software works on the surface.


White box QA is when the internal aspect of the software is tested. We feel this is an important part of software testing because it identifies deeper issues that black box testing might miss. There are several steps to this process from testing it with public and private APIs, testing the code, testing forms of mutations and ensuring the software is running as it should.


Examples of Automated Software for QA


Automated software tests the software using predetermined tests the software might encounter at the hands of the user. We recommend this kind of testing as it allows you to get a more realistic feel of how your software will perform. Did you know that there has been controversy about the use of SQA software? Some feel that it will interfere with the job of the engineer. In fact, the only thing that the automated SQA software does is to streamline the job of the software development engineer. After all, there is plenty of software that needs to be developed and anything that can be done to make this process faster is a welcome addition to the process.


Getting rid of bugs after the software has been completely developed can be extremely difficult. This is why we utilize the Scrum methodology throughout the development process. This allows us to test the software for bugs as it is developed and can save a considerable amount of time in the long run.
