Introduction
Testers use automation tools, network traffic analyzers, debugging tools ... and the brain to perform what is called "manual testing" to control product quality. This phrase is unfortunate for the reason that the testing process cannot be reduced to muscle activity alone. Moreover, the hands are only slightly involved in this process. But the result depends on the work of the nervous system as a whole. In this article I will try to reveal how you can apply knowledge about human higher nervous activity to successfully solve testing problems.
Type of nervous system
Outstanding physiologist Ivan Pavlov, studying reflexes, discovered individual differences in the properties of the nervous system in higher animals. For example, some dogs demonstrated the rapid formation of positive conditioned reflexes, but the development of inhibitory processes required much more time. Others showed the opposite properties of the nervous system.
On the basis of Pavlov's work, an experiment was carried out at a weaving factory. It has been noticed that some machine operators unravel the thread as soon as knots appear, while others wait until the last. But in the end, the result was approximately equal for all. The experimenters asked the machine operators, who were waiting until the last, to immediately untangle the knots, and to others - to rest longer, but to correct already more severe breakdowns. It turned out that the exchange of strategies led to a deterioration in production.
So, when taking a task for testing, you need to focus not only on priority, but also on the individual rhythm of work. If you just closed a complex function, it can be useful to move to an easy task, even if it has a low priority. Otherwise, due to overwork of the nervous system, the quality of testing may suffer greatly. However, there are often people who quickly and successfully cope with several difficult tasks in a row, but after they need a long rest.

In the process of work, the tester is constantly faced with the limitations imposed by the peculiarities of the human psyche. But despite this, the human brain is currently the most effective tool for finding bugs. But, like any other tool, it needs to be mastered to achieve positive results. Using the strengths of the psyche and bypassing limitations allows you to achieve an effect that is not yet available to automation tools.
