The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. An example of a basic software release life cycle
The goal of continuous testing is to provide fast and continuous feedback regarding the level of business risk in the latest build or release candidate. [2] This information can then be used to determine if the software is ready to progress through the delivery pipeline at any given time.
Development, testing, acceptance and production (DTAP) [1] [2] is a phased approach to software testing and deployment. The four letters in DTAP denote the following common steps: Development: The program or component is developed on a development system. This development environment might have no testing capabilities.
Common names of versions during different stages in software development. Release management is the process of managing, planning, scheduling and controlling a software build through different stages and environments; it includes testing and deploying software releases. [1] [2]
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates. [3]
For example, the 1985 DOD-STD-2167 [2] mentions (in section 4.1.2): "During software development, more than one iteration of the software development cycle may be in progress at the same time." and "This process may be described as an 'evolutionary acquisition' or 'incremental build' approach."

Software testing typically includes handling software bugs – a defect in the code that causes an undesirable result. [11]: 31 Bugs generally slow testing progress and involve programmer assistance to debug and fix. Not all defects cause a failure. For example, a defect in dead code will not be considered a failure.
