Software Testing - Life Cycle Software Development

SDLC or software development software engineering life cycle is a term that includes all software development processes and implementation. Includes methods that are used to design and develop systems. A software engineering concept behind the SDLC many types of software development methodologies. The methods described are those that help create a framework that can be used as a basis for the development of information systems

Tests are sometimes misinterpreted. People believe that the test be performed after the programming is made for a system or software. In reality must be made at all levels of the development cycle.

The most common types of tests related to the development process are:

O-unit test: this is the first level of the test cycle of software testing. Overall, the product is divided into small units. Testing of these units are called, like unit tests.

or test the system: a system level is the level of unit testing. Whenever there is a great system and programmers are the codification of the different units are combined and the combined system test is a test system integration test.

O Functional Test: When the system is built, it tested its functionality. To test the operating system I like is called functional tests.

o Automated Testing: This is one of the most beautiful way to increase efficiency, productivity and accuracy of the software. It simplifies testing practices by reducing the human effort involved. In this case, we create and execute automated test those who use automated tools. Automated Test Tool Reiterates the predefined steps and results more accurate than manual testing.

Alpha Testing: Alpha happens after the code has been involved in control most of its functionality before the user begins to use it. Sometimes, a select group of users involved in the test. In most cases this test will be conducted in-house/small scale. or by a testing company out in close collaboration with the Department of Software Engineering.

o Performance Testing: This test takes place when the product is fully developed. Its main objective is to identify the performance of the software as guidelines client relationship.

o Acceptance Testing: Testing system software with the intent to confirm accuracy and efficiency of product acceptance and customer.

Sometimes the software is so complex and large that is virtually impossible to test it out entirely. Before ending the software testing, we should keep in mind some things:

- Guidelines for trials must be respected

- The test cases should cover all aspects of the software.

- Bugs in software should be minimal.

- All test cases which should be tested at least once.

Once testing is complete software makes the system or software is introduced into the market for the user.
