Quality assurance testing explained

Quality assurance testing is the process of evaluating a system or its components to check whether it meets specified requirements or not. To put it simply, software QA is the execution of a sequence of actions to identify gaps, errors, and bugs that conflict with the requirements.

In this article, we outline the quality assurance process, overview QA procedures, and discover what does a quality assurance manager do.

Introduction: The Basics of Software Testing & Quality Assurance

Software quality assurance helps to check the fulfilment of all business scenarios and user requirements, as well as identify all possible problems and bugs in IT products.

Oftentimes, the terms “testing”, “quality assurance” and “quality control” are either confused or used interchangeably. However, these terms characterize quite distinct processes such as:

  • Testing which means the process of finding bugs;
  • QC (Quality Control) which is the implementation of the testing process like a case description, searching, and establishing defects;
  • QA (Quality Assurance) is the creation of a control system to prevent bugs during the software development stage and reduce the number of defects at the testing stage. It is the construction of the testing process.

We asked quality assurance experts who work in our software development team to review in detail the QA software testing process and explain why the QA testing services are necessary for any software development project.

Stay tuned.

Why Do We Need QA in Software Development and QA Specialists?

Indeed, can’t developers test products themselves?

Five to six years ago, this issue was widely debated in IT communities. But in 2022, it’s clear that a software testing services company will not be out of work. Testing in IT should be carried out by qualified specialists.

So, what is QA testing? What do quality assurance specialists do?

  • They check all interactions between different pieces of code and environments which are not part of the program that they have built themselves;
  • In the process of testing, they put themselves in the shoes of a user who the product is being created to;
  • The logic of software QA engineers work is not solely based on the creation of software but also includes the possibility of its breakdown.

When Does Quality Assurance Testing Software Start?

Testing at the right time reduces the cost and time to rework and create error-free software to be delivered to the client. In a software outsourcing company, the testing starts at the requirements gathering stage and continues till the software is deployed.

However, it also varies depending on the development model used. For example, in the Waterfall model, testing is performed during the testing phase. In an Agile model, testing is performed at the end of each iteration. The application is tested at the end of the project again.

Testing is conducted in different forms at each stage of the software development life cycle:

  • Requirements gathering phase, analysis, and verification of requirements are also referred to as testing;
  • During the design phase, the issues connected with design improvement are considered a part of testing;
  • Testing performed by software developers upon completion of the app’s code is also categorized as testing.

When Is The Right Moment To Stop The Software QA Process?

It’s challenging to determine when to stop testing as it might seem a never-ending process and no one can claim that a given software is 100% tested.

Consider and thoroughly analyze the following to realize the moment to stop the testing process:

  • Testing terms;
  • Decrease in the error rate;
  • No more high-priority bugs.

What Are The Types Of Software Testing?

For a better understanding of software testing approaches, it’s essential to know the types of software testing. Below you can have a look at the main types that we identify.

Types of software testing by the degree of automation

Any testing can be performed both manually and using automation tools. All quality testers are divided into various groups according to software security, performance, usability. But in the broad sense, they can be divided into those who perform manual and automated testing.

Manual software testing

Мanual software testing is a type of software testing when a QA engineer manually runs tests without any automation.

Automated software testing

Automated software testing is performed using frameworks such as Selenium, PHPUnit, Mockery. It aims to reduce the cost and risks related to the human factor. This type of testing is especially efficient on long-term projects with frequent releases and large-scale regression.

Each of the testing types has its area of ​​application because 100% automation is unachievable. For example, usability testing always has to be done manually. So, what does a QA engineer do in each of these cases? The key differences between manual and automated testing are in the table below.

Differences Between Manual and Automated Testing: manual testing  is time-consuming, monotous and tiring, all the tests run manually. Automated testing is performed through specialized tools, saves time, budget and human resources, is recommended for stable systems.

Types of software testing according to the test object

According to the test object, custom software testing is normally divided into functional and non-functional testing.

Software functional testing

Software functional testing checks the part of the system that is particularly necessary for a user to complete a business scenario from start to finish. It is performed before non-functional testing. A good example of what is functional testing in software testing would be navigation through forum sections.

Software functional testing methods and techniques include:

  • Unit testing;
  • Gray box testing;
  • Black box testing;
  • White box testing;
  • User testing;
  • Regression testing;
  • Smoke testing;
  • Exploratory testing.

All of these are pretty specific and are mostly talked about among QA specialists and developers.

Software non-functional testing

Software non-functional testing is essential to validate the performance of a given system under various conditions that can impact user satisfaction. Here, we’re talking about reliability, usability, scalability.

By the way, to improve your Magento-based website performance, have a look at what NEKLO experts offer in this article.

Software non-functional testing methods and techniques include:

  • Security testing

Security testing is used to identify software vulnerability to various attacks, such as cross-site scripting (attacks in which malicious scripts are injected into websites) or SQL injection (a vulnerability that allows an attacker to interfere with the queries that an application makes to its database).

  • Localization testing

Localization testing is the process of adapting a product for a specific country or region. Such a software application usually has already previously been translated into multiple languages.

  • Usability testing

Usability testing aims to test the user-friendliness of a software application and the clarity of the software application interface.

Types of software testing according to the positivity of the scenario

The list here is rather brief. It includes:

Negative software testing

This type of software and app testing consists of entering invalid values and committing invalid actions so that to check if the given software or app behaves correctly. It doesn’t act improperly and issues a human-readable error message.

Positive software testing

Positive testing includes checking if the program works correctly when proper data is entered. The result here is no errors are generated and the software behaves the way it is meant to.

Quality Assurance Process Steps: Software Testing Stages

Software Testing Stages in QA process: requirement analysis, planning, test case development, testing environment setup, test execution, cycle closure.
Software testing stages

Here we present the ways to describe the stages of software testing. We believe the best way to define what is a QA process is through the software testing life cycle.

The Software Testing Life Cycle model (STLC) consists of six main stages that include:

Requirement analysis

At this stage, testers examine the requirements from a software testing perspective and communicate with the client for a detailed understanding. Also, if necessary, they perform a feasibility study of automation.

QA specialists often have to deal with situations where requirements are missing or unclear. In those cases, a software tester has to utilize methods and tools to organize testing in the absence of ideal requirements on the project.

Test planning

At this stage, it is necessary to:

  • Develop a testing strategy;
  • Identify risks;
  • Select tools for testing;
  • Assign roles in the team.

All these points are recorded as a test plan and test strategy.

Test case development

Writing a test case means creating a textual description of the testing process for a portion or feature of the project. Test cases are necessary for team members to check the program and get acquainted without reading the entire code.

Testing environment set up

This step is necessary to prepare all the conditions for an effective testing process. It includes setting up a test server, setting up a network, setting up test PCs and devices, and generating test data.

Test execution

The QC team starts executing test cases according to the test plans and generates bug reports. Also, bugs are quite often validated at this stage.

Cycle closure

The last step in the software testing life cycle involves kind of a meeting of the testing team members to evaluate the project performance.

Conclusion: Recap On The QA Process

Software quality assurance is a very significant part of software development. It can’t be underestimated as it helps to receive a good-looking and good-working software solution, a software that functions properly.
