Best Software Testing Companies: Only Simple Program Can Be Completely Tested

Some inexperienced testers believe the myth that it is really possible to conduct the complete testing. They always feel guilty, because no matter how hard they may work, no matter how carefully they may plan their work, no matter how much time they may spend doing their work, no matter how many personnel and equipment items may be involved in the testing process, anyway software programs will have defects. There are almost no such tasks that could confuse the staff of the best software testing companies because they have been solving the most difficult challenges for many years.

And to prevent you from being misled by the wrong statement, here are three reasons why the complete testing can never be done.

1. The number of all possible combinations of input data is too large, so it simply cannot be completely checked.
2. The number of all possible sequences of the program code execution is also too large so that to be checked completely.
3. The user interface of the program (including all the possible combinations of the user’s actions and movements around the program) is usually too complex to be completely tested.

Mobile app testing companies are established to help mobile app developers and users to enjoy the smooth performance of their programs. The firms run mobile app testing across a multitude of devices to be sure that only high quality applications will be made available to the public.

If you have a simple program at hand then you should check its response to the input at each moment of its operation

You should try to enter the data when their program does not expect it. Do not wait till a question mark and a blinking cursor appear – enter the data (figures), while the program is still processing the previous data, displaying the result or showing a message.

In many systems, a software interrupt is generated in response to keystrokes. This interrupt means that the processor must temporarily suspend its operation and read data from the input stream. After processing the interrupt, the computer continues to execute the program. To make sure that the program works as intended you need to interrupt the program after each command.
Software testing service providers are highly qualified specialists who tirelessly and selflessly perform their professional responsibilities and duties – identify all kinds of problems in software products under development.
