Top Software Testing Companies and Iterative Model of The Life Cycle
Not all models of software development life cycle can be applied successively. There are also iterative (or incremental) models which require different approach. In these models, instead of a one long sequence of events, the entire lifecycle of a software product is divided into a number of separate short cycles. At that each of them includes all the same basic stages of the software development life cycle. These short cycles are called iterations. Each of the iterations is a fixed timebox where features of a system are developed individually, and then the feature is added to the previously developed functionality.
In iterative development. top software testing companies verify feature code in repeated cycles.
Iterative software development approach does not rely on a complete set of requirements for commencement of work on the product. The development process may start after elicitation and gathering of some of the functional requirements which can be further expanded and modified. Term “iteration” is similar to repetition. So, iterative development consists of several cycles of analyses therefore this model allows you to build and improve the product step by step, in other words, a new version of software is produced at the end of each iteration of this model.
NB! Experts of mobile testing companies insistently ask you to check your mobile apps for defects on timely basis otherwise you may run the risk of releasing low quality software and damage your brand’s reputation.
A simplified version of a common iterative model consists of four main stages, which are repeated in each of the iterations (plan-do-check-act):
- requirements elicitation and analysis;
- design and planning are performed in accordance with the requirements. Besides, an already existing feature can be individually redesigned if needed, or a new feature can be designed;
- development and testing involve coding, integration and investigation of the new feature;
- review phase encompasses evaluation, revision of the current requirements and suggestions on their improvements or modifications.
List of software testing companies is available for you to be able to choose desirable testing specialists without problems. It is an easy and common way to hire highly experienced and reliable providers of qa services. You deserve to pay less for professional work.
