Stability testing is called a method of testing that verifies a Program’s power to defy every condition and make sure whether the program will have the ability to deal with or function well within an acceptable time period.Stability is just one of the critical elements of software. It is A sturdy characteristic of software that improves the quality attribute. Only with this non-functional sort of software testing, software can be recognized as continuous software.Software is considered to be compatible only if it can manage Anticipated load in real and positive problems. A system is tested in order to confirm the behaviour or reaction in a set manner when put under a significant load. To accomplish this, an artificial environment is made and the response of applications is noted down for a particular time period. This sort of testing is done with a sole intention to point out fluctuations faced by consumable resources of time. Within this procedure for testing the data obtained will be examined and the system performance will be optimized.

Factors which are responsible for doing test are as follows:

• Short life span of applications
• once the software is not able to satisfy the requirements.
• Making software easier.
• Increase reliability of applications.
• Gives freedom to developers to bring change in applications.

Software is Stability Testing for its stability by placing it under intense Conditions which will definitely occur once it belongs in the hands of customer. By doing this, a programmer achieves confidence that applications developed is reliable.Frequently we see that software Developers aren’t open to bring changes within an application as it may become a reason for flaws or sometimes break the program. The programmers are scared with a nightmare of bearing an enormous quantity of expense in changing the program.It comparatively aids in identifying the flaws of applications when placed under specific harsh conditions.It also assists in determining the stability of applications in response to its behaviour.Such testing also helps in repairing the flaws or bugs which enhances the stability of applications.

By assessing the performance of applications, the expected life of the software increases.It is likely to be Thought that stability of a program can be achieved only by undergoing test on a constant basis. This can be achieved by following a very simple code to set a software system. It is also noted that with strict amount of testing the shelf life of a program can be extended. Additionally, it contributes to creating adaptive software’s that adjusts readily and is responsive to requirements and needs of individuals. The life of applications stops when found to be incapable of altering in accordance with the customer’s requirements.
