What is Software Quality Assurance And Types of Testing?
In any industry, quality is paramount. This holds for the software industry too. As global shipments of software rival or even exceed the manufacturing sector by leaps and bounds, Quality Assurance in software is as relevant as it is in manufacturing. According to Wikipedia, software quality assurance, also known as testing, quality assurance testing or QA “is defined as an investigation that is conducted to provide key stakeholders in an organization with specific inputs about the quality of the software product or service that is being developed.”.
Software testing can also provide an independent view of the quality of your software to allow the stakeholders to understand the risks of deploying it. software quality assurance ensures that the product produced is high-quality and conforms to industry norms. Every entrepreneur and business leader needs to know what is quality assurance to ensure business success.
The Importance of quality assurance for software development
In the software industry, Quality Assurance is more commonly known as Software Quality Testing or Software Testing. Software testing is the process of ensuring that your software delivered to the customer is of acceptable quality and performs as desired. Softwares that are extensively tested are more stable than untested software and showcase reliability, predictability, and use limited resources.
Well-tested software is less prone to instability, data theft, and data loss. For enterprises, application quality and testing are critical as many enterprise workflows are completely dependent on the software that they use. A lack of software quality due to improper testing can also result in the loss of life and property as showcased by the recent example of a software glitch in the Boeing 737 Max aircraft pilot guidance system, which caused a plane crash and the irreplaceable loss of hundreds of lives.
How to test?
A common question that people ask is about the quality assurance testing types. The answer, however, is not that simple. Before you learn more about quality assurance and types of testing, you must answer an important question: How to create a testing strategy?
Creating an effective software testing strategy is as important as testing itself. Before knowing the various types of software quality assurance, it is important to know how to build an effective software testing strategy to ensure coverage and quality at all times.According to Wikipedia, a test strategy is an outline that describes the testing approach of the software development cycle. It is created to inform project managers, testers, and developers about some key issues of the testing process. This includes the testing objective, methods of testing new functions, total time and resources required for the project, and the testing environment. Similar to other aspects of a business, software testing also involves following a set strategy to ensure that business and product goals are met.
Choosing an effective software testing methodology
Once an effective strategy is determined, we then need to categorize the approach or the methodology used to test software. Software testing can either be performed manually or automatically.
1.Manual testing is performed by software test engineers and professionals. They test and verify various aspects of your software according to test cases and test plans. Many software requires to be tested by test engineers for various changes for which automation test scripts cannot be created easily. Typical examples are colour rendition, user experience, and design. Manual testing is relatively low-cost compared to automation testing but is labour intensive and subject to human error and bias.
2.Automation testing is the creation of automated test scripts that allow your software to be tested without human intervention. Repetitive, labour-intensive tasks like data input validation and unit tests can easily be automated by test engineers to ensure that these are run every time a new change is made to the code without requiring the assignment of an engineer to test that change. Automation testing requires specialized teams that are adept at creating test scripts according to the automation testing suites used by their organization. Their requirement of specialized software and teams makes automation testing costlier to implement. Automation testing typically pays off in the long run as automation scripts written by specialist testers typically manage to uncover a much higher number of bugs compared to manual testing.
