Quality Assurance IT systems

Testing of the software development process.

Dynamic economic development in the world makes the computerization of virtually all of its sectors is essential. The process of computerization concerns in particular the financial sector (banks, insurance companies, brokerage houses, mutual funds investment, pension, etc.) Public institutions (the uniformed services, health care, international organizations, central administration, etc.), industry, trade and services (power, gas, telecommunications, enterprise Production etc.), and others. To ensure the reliability and quality of the produced software is necessary to position pressure on the testing process during the manufacture and maintenance of the software.

The test is obvious and plays an increasingly important role in every industry. This is because the systems entered in virtually every area of business.

Testing program, we are going to raise its quality by detecting and repairing as many errors. It raises the reliability, and thus its value.

Functional tests:

We focus mainly on carrying out Test of functional , whose aim is to validation of software behavior into account assumptions functional contained in the requirements and specifications. The functionality of a business is generally defined as the activity that supports the execution of routine business activities. Functional tests by performing a series of tests achieve greater coverage Part of the software, which allows users to completion performed routine activities. With the exception of small programs functional tests are in principle character of "black-box". Mainly based on analysis of the specification of the outer on the basis of which creates a different test cases. To this end, the technology division of equivalence classes, limit analysis and error guessing. During the design of functional test cases should focus mainly on preparation of relevant test data sets. They constitute a key role for the successive carrying out functional tests.
