Software Testing Services Are Only Aimed At Verifying Quality of IT Products, Aren’t They?
Software testing services are delivered to check how applications work and if this behavior is in compliance with the requirements specification.
The goal of software tester is to verify performance parameters of the program, isn’t it?
Testing is often referred to as the process of running a program so that to find as many defects as possible. Also, it is carried out to obtain information about the program’s quality.
Testing is also regarded as a process of determining correctness of a software application.
- This definition is meaningless’, since no matter how carefully and exhaustively you test a program – it is not enough to conclude that it is working properly.
- In addition, it is wrong’, as the program cannot work 100% properly.
- Such a definition presupposes a bad fortune if a tester intends to confirm that the program is working properly, his efforts fail every time when he identifies a defect.
- Taking the definition as a basis, the tester starts working ineffectively: if you think that no defects will be present in the program, then the probability of finding them is greatly reduced.
Performance testing companies are capable of making your software functionally correct. They determine how fast every feature of the program performs under an expected workload. Such verification helps to identify and eliminate performance bottlenecks.
It is impossible to ascertain that the program works correctly
In fact, no program can be fully tested (unless it is absolutely simple). It lead to another statement: it is impossible to verify that the program works correctly. Failure can occur at any time in millions of situations which have not been checked by you.
The program is not working properly
According to rough estimates, the defect detection and correction are costly processes; they consume 40-80 percent of the total cost of software development. Companies pay such big money in order not to be sure that the programs work. They are forced to spend the money because their programs do not work – they contain bugs, and the company owners want these bugs to be fixed. No matter how well the development process proceeds, despite the most advanced techniques to be used to facilitate it, defects will be always introduced in the products.
