software development life cycle (SDLC)

The Software Development Life Cycle (SDLC) deals with software testing in the life cycle characterized by software requirements, software design, realization and coding, and maintenance.

In the Software Development Life Cycle, software testing can be performed during the different phases of the life cycle through manual inspection, through end-to-end testing, simulation, static analysis, verification and regression testing. Thus, requirements definition, which is about correctness, completeness and consistency, is done manually and with end-to-end testing. The same applies to the design phase, in which simulations are also used. In this software life cycle phase, the focus is on the system structure and its completeness, interfaces and faulty logic. In the realization life phase, the program codes arechecked and executed by means of static and dynamic analyses, and during maintenance, errors are eliminated with regression tests. During this test, the test cases are processed several times. The repeated processing prevents as far as possible that changes in the software or further developments have caused new malfunctions.
