Often (most always) at the design stage it is impossible to predict the system bottlenecks. This is largely due to the inaccuracy of the projected peak load and in the context of specific modules. Even if you follow all the basic principles for developing systems of heavy duty, you are likely to be problems with [...]
This question is not idle, and very important. There are many companies where there are no test cases, that is, testing is, the department is testing, and test cases nobody writes and does not use. Moreover, there are more companies, where test cases are formally - they can not be used. To wave under the [...]
Virtually any modern web application you want to or not, uses cookies. And, of course, that they, like any other part of the application, require the attention of the tester. So let us try to understand what cookies are and what they eat, and most importantly - why.
Cookies - who are they?
Before proceeding to [...]
In terms of performance testing, all systems are divided into:
Heavy-performance systems. Hundreds of thousands of users, tens of millions of hits a day, dozens of gigabytes of data, terabytes of traffic. Yandex.ru, for example.
Low-performance systems. For example, a system of B2B interaction (inter-enterprise collaboration system). Such a system typically use about 100-500 employees [...]
A similar view is shared by the leaders of software companies, seeking to reduce the implicit costs of production. Although many of them are not noticeable at first glance, they are quite noticeable effect on the financial result. Among the implicit costs include higher costs due to inefficient testing of developed programs.
Any more or [...]
Periodically, throughout my work in the area of testing, I, like many of us tried to find as much information in their field, in order to facilitate and streamline the process of finding defects. It so happens that part of the testing of economic programs, in particular, 1C Company, the information I have, alas, is [...]
Not arise if you have the feeling that many of the software development projects in which you participated as a developer, something similar? Namely, for different projects, different programmers admit the same, standard error. Of course, we are not talking about syntax errors. This is a "problematic" code, which initially failed to work properly, but [...]
Although the test can distinguish several different processes, Terms such as testing, debugging, evidence control and test, often used as synonyms, and, unfortunately, for different people have different meanings. Although the standard, accepted definitions of these terms not to attempt to formulate them was made at a symposium on testing programs. Our classification of different [...]
New programming methodology, such as Radip application development (RAD), Extreme Programming, have led to intensive development of automated testing. The main feature of these methodologies is the ability to produce different versions of the software product of the increasing volume of high frequency. Hence, the current testing has become an iterative nature - each new [...]
