The abbreviation QA is an English phrase quality assurance, in Russian it sounds like “quality assurance”. The profession of a QA engineer, or tester, is in high demand in modern conditions. These specialists check the operation of computer programs and applications. They monitor that these products perform their tasks, protect applications from hackers, check their operation on various devices and in different operating systems.
In other words the QA engineer is

QA engineers develop real instructions for testing — test cases. In simple terms, it looks like this: analysts write lebanon whatsapp number data requirements — what should be at the input, what data, how it is process, what the result should look like; testers write step-by-step instructions for checking the software product for compliance with these requirements.
Types of testing
A QA engineer checks how the user will be able to use the software product, even if these methods are consider impossible. To do this, the software is test from the moment the technical task is develop and then at each stage. Depending on what exactly is being test, when and where, testing can be:
Static . It is carri out even before the launch of the program, at the project stage. The QA engineer checks the correctness of the writing of codes, specifications.
This is the next stage after static
The tester launches the program and during its operation checks the correctness of the actions perform, controls the response time, determines how much the load on the memory and processor increases during this check.
Functional . The specialist checks whether the software product’s operation corresponds to taiwanese, as well as bilingual text the technical specifications and whether the actual result differs from what was intend to be obtain. At this stage, the cg leads tester also studies the system’s security – how resistant it is to viruses, hacker attacks, and leakage of personal data.
