Performance testing is method to determine or examine how many users load can sustain our application before too late. Because during use of the application if application crash or respond slow user does not want to use again.
If any application or website has large number of user interacts at one time like ecommerce application, social networking application, travel and logistic application and etc. They website has required to test our application for performance before too late.
Precise testing solution provides the performance testing services with help of market available best tool. In our performance testing services we cover all performance testing method. They are mention below.
Performance Testing covers a broad range of engineering or functional evaluations where a material, product, system, or person is not specified by detailed material or component specifications: rather, emphasis is on the final measurable performance characteristics.
Performance testing can refer to the assessment of the performance of a human examinee. For example, a behind-the-wheel driving test is a performance test of whether a person is able to perform the functions of a competent driver of an automobile.
In the computer industry, software performance testing is used to determine the speed or effectiveness of a computer, network, software program or device. This process can involve quantitative tests done in a lab, such as measuring the response time or the number of MIPS (millions of instructions per second) at which a system functions. Qualitative attributes such as reliability, scalability and interoperability may also be evaluated. Performance testing is often done in conjunction with stress testing.
Load testing is the process of putting demand on a system or device and measuring its response.
The term load testing is used in different ways in the professional software testing community. Load testing generally refers to the practice of modeling the expected usage of a software program by simulating multiple users accessing the program concurrently. As such, this testing is most relevant for multi-user systems, often one built using a client/server model, such as web servers. However, other types of software systems can also be load tested. For example, a word processor or graphics editor can be forced to read an extremely large document; or a financial package can be forced to generate a report based on several years’ worth of data. The most accurate load testing occurs with actual, rather than theoretical, results.
Volume Testing belongs to the group of non-functional tests, which are often misunderstood and/or used interchangeably. Volume testing refers to testing a software application with a certain amount of data. This amount can, in generic terms, be the database size or it could also be the size of an interface file that is the subject of volume testing. For example, if you want to volume test your application with a specific database size, you will expand your database to that size and then test the application’s performance on it. Another example could be when there is a requirement for your application to interact with an interface file (could be any file such as .dat, .xml); this interaction could be reading and/or writing on to/from the file. You will create a sample file of the size you want and then test the application’s functionality with that file in order to test the performance.
Stress testing is a form of testing that is used to determine the stability of a given system or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results. Stress testing may have a more specific meaning in certain industries.
Verifies the redundancy mechanism when the system is under load. In other word, testing where a system is made to fail under load, to verify whether standby systems are correctly used to mention services.
Testing conduct over an extended period of time to reveal resource usage problem such as memory leaks.
