After getting acquainted with
TesterLabs, you could come to the conclusion that the main focus of training in our
training center is software testing.
And it really is. The process of software testing in the general cycle of software development is not the last place. After all, if the purpose of the "Coding" stage is directly to create a software product, then the purpose of "Testing" is to make the created product as efficient as possible and meet customer expectations.
But this statement is a bit generalized and inaccurate, as it is based on the fact that many people put the concepts of "testing" and "QA" on the same level.
It should be clearly understood that:
QA (QualityAssurance) is a process of quality assurance and is not just about testing. According to Wikipedia: Quality assurance is the process or result of the formation of the necessary properties and characteristics of products as they are created, as well as the maintenance of these characteristics during storage, transportation and operation of products. In other words, QA is a concern about the quality of software that arises in the very early stages of development, right up to planning, and does not leave it until the last stage.
Software testing is only one of the areas of QA, which is the study of the software product, as a result of which you can determine the degree of compliance of the actual behavior of the software and its expected (planned) behavior. Therefore, the testing process is not just a process of finding errors, as inexperienced job applicants often like to say. Testing is multifaceted and has its own types, levels and methods, which you can get acquainted with in our Knowledge Base!

Why is
testing necessary?
In this section, we will
look at the basic concepts and principles used in the testing process. We will learn
what, in fact, is testing, what it is needed for and who does it. Consider the
goals, principles and main stages of testing. We will feel what the psychological
state of a real tester should be like and finally destroy some myths about testing.
We are sure you will be interested.
Let's start with what "testing" is. To begin with, let's abstract from dry academic definitions and look at this concept from the perspective of the everyday user.
When we test something, we ask ourselves a simple question: "Does it work the way we expect?" or, in other words: does the actual behavior of the test object meet our expectations? If the answer is yes - fine, if not - we are deceived in our expectations, so we need to fix something.
Testing is necessary because we all make mistakes. Some of them can be insignificant, while others can have very devastating consequences. Everything that is created by man can contain errors (so we, the people, are arranged). That is why any product needs to be tested before it can be used effectively and safely. The same is true for software.
Software - computer programs, functions, as well as their documentation and data related to the operation of a computer system.
Computer technology is penetrating deeper into our daily lives. The software controls the operation of many things around us - from mobile phones and computers to washing machines and credit cards. In any case, we have all encountered certain errors in the programs: a text editor that hangs relentlessly when working on a thesis project, an ATM "ate" the card or just a site that does not load - all this does not make it easier for us. life.
However, not all errors are equally dangerous - risk levels may differ for different software systems.
Risk:
- a factor that may lead to negative consequences in the future; as a rule, it is expressed through the probability of occurrence of such consequences and their influence on the system.
- what has not yet happened and may not happen at all; potential problem.
In addition, the level of risk will depend on the likelihood of adverse effects.
For example, the same minor error, say a typo, can have completely different levels of risk for different programs:
- a typo in the description of interests on a personal page on a social network is unlikely to have serious consequences, unless it will make your friends smile;
- the same simple typo, made in the description of the activities of a large company posted on its website, is already dangerous, as it directly indicates the unprofessionalism of its employees;
- a typo in the program code that calculates the levels of radiation in the X-ray machine (for example, 100 instead of 10) can have the most disappointing consequences - damage to human health and safety will result in loss of confidence in the company and lawsuits with many zeros.
