Types of Software Errors to Be Dealt With By Quality Assurance Companies

Race condition

The traditional race condition is described like this:

Suppose two events are expected to happen in the system, let us call them “A” and “B”. Any of them may occur first. But if event A occurs first, the program will continue running, however, if it is for event B to occur first in this race, the program will start glitching (or will develop a glitch). A programmer believed that event A would always be the first to happen, and, of course, he did not expect that B could be the winner of the race.

It is not easy to test race conditions. They mostly occur in the systems where cooperating processes and interaction points are executed in parallel, and also in real-time multi-user systems. (Errors of such systems are difficult to reproduce, and the process of identifying these errors is complicated because it usually takes a lot of time.

Quality assurance companies are capable of identifying any problems in software programs whether it be glitches, bugs, flaws, defects or other errors that prevent them from working properly.

Overload

It happens that a program cannot cope with the increased loads. For example, it may be unable to withstand an intensive and prolonged operation as well as deal with large amounts of data. In addition, failures may occur due to a lack of memory on the hard drive or lack of other necessary resources. Each program has its own defined load limits. The question is whether or not actual functions of the program and its requirements to the resources meet the specifications and how the program will behave under peak load conditions.

Professionals of penetration testing companies land a helping hand to everyone who wants to protect their sensitive data. Confidential information should be kept secure so that no invader could steal it and disclose it to your competitors.

Hardware

Programs may send incorrect data to the devices, ignore error messages sent from these devices, try to use devices that are inaccessible (already in use) or are unavailable at all. Even if a necessary device is broken, the program should understand this, and not to crash when attempting to access it.
Software testing services are available to evaluate capability or a feature of a system or app in order to determine if it complies with the required results. On obtaining information about quality of the product it is much easier to fix all the problems identified in it.
