What is the purpose of software testing?

In order to ensure the quality and reliability of the software; it is necessary to conduct an accurate technical review of the software before the end of each development stage such as analysis and design. However, due to the limitations of people's abilities, the review could not find all the mistakes. And a lot of errors are introduced during the coding phase. These errors and defects will eventually be revealed if they are left behind when the software delivery is put into operation. But by then, not only will the cost of correcting these errors be higher, but it will often have very bad consequences.



Software testing spans two phases in the software lifetime: usually, after each module is written, it is tested called a unit test. Coding and unit testing are part of the same phase of software life. After this phase is over, various final testing is performed on the software system. This is another phase of the software life cycle, the testing phase, which is usually undertaken by a dedicated tester. A large number of statistics show that the workload of software testing services often accounts for more than 40% of the total workload of software development. In extreme cases, the cost of testing software that is related to human life safety may be equivalent to the total development steps of software engineering. Therefore, we must attach great importance to software testing, and never think that the software development work is almost completed after writing the program. In fact, there is about the same amount of development work to be completed. For testing purposes only, its goal is to find errors in the software, but finding errors is not our ultimate goal. The fundamental goal of software engineering is to develop high-quality software that fully meets the needs of users.

Purpose of Software Testing 

There are two completely different test objectives based on different positions. From the user's point of view, it is generally desirable to expose errors and defects trapped in the software through software testing services to consider whether the product is acceptable. From the perspective of the software developer, it is hoped that the test will become a process that indicates that there is no error in the software product, verify that the software has correctly fulfilled the user's requirements, and establish the user's confidence in the quality of the software. Because there are often many unexpected problems in the program, they may be overlooked, and many hidden errors may only be exposed in certain circumstance.  Since the goal of testing is to expose errors in the program, it is not appropriate from a psychological point of view to be tested by the programmer himself. Therefore, in the comprehensive testing phase, the testing team is usually composed of other personnel to complete the testing work. In addition, it should be recognized that testing must not prove that the program is correct. Even after the most rigorous testing, there may still be undetected errors hidden in the program. The test can only find errors in the program, and can't prove that there are no errors in the program.

Top Trends in Smart Home Automation

"Good evening, home!" Then the lights, the sounds, and the TV sets and internal appliances go out, the curtains close, the air conditioning changes temperature and the external lighting is accessed. The scene may seem unusual, but smart home automation is closer to the real than ever before. Today, with a simple touch of a smartphone and a tablet or even voice recognition and face-reading, you can take control across your home and business in an interactive and efficient way. The automation services available in the market grow by leaps and bounds and offer technology ranging from opening doors to curtain manipulation and heating the stove, fireplace, and bathtub by electronic or voice commands. The advantages are the rationalization of energy consumption, comfort, convenience, interactivity, safety, reduction of domestic work and, consequently, improvement of well-being. Wireless technologies for automation infrastructure are increasingly popular. In the past, systems re...

Advantages of implementing QA Transformation services

It can be said that the QA Transformation services are a set of activities, processes or tasks, in which they are planned and systematized, which will be necessary during the development of the software to ensure the quality of the same. It intends to give the greatest confidence in which the created product will meet the quality requirements since the assurance focuses on identifying and evaluating the defects that may affect the performance of the software, it can be said that its primary purpose is to ensure that the needs of the users are being met. In the same way, this process intends to give a global approach to quality, in clear ways, apart from the use of quality in the product developed, similarly to the most and software engineering processes , focused on technical reviews, strategies, control of software documentation and quality measurement mechanisms, is what software assurance implies . Now, the implementation of a quality management system in the organization entails...

The role of governance risk and compliance management in corporate business

The organizations have seen their boards of director’s press for improved governance structures in their organizations. That pressure for better governance is not a recent phenomenon. New rules also boosted the increase in governance around internal processes. And the regulatory agencies are not the only catalysts for change. The expectations of investors and other stakeholders in relation to governance risk and compliance are increasing. More than ever, stakeholders are holding management accountable for the effectiveness of its overall governance process. This change is real and significant and, probably, it amounts to an expectation of greater bond of the council in the means by which the government is organized and carried out. Although the direct link of the board may be realistic in smaller organizations, banks, and larger insurance companies may find those requirements challenging. In general, the council has responded by strengthening internal policies and establishin...
