Software performance testing is the process of validating whether given software/application has potential to perform in terms of performance, responsiveness and scalability under specific load. Responsiveness refers to the application has the ability to meet pre-determined objectives for better output while scalability is the number of activities can be handled within the given time. Performance testing is key factor in validating the quality of a software application or environment under test. In agile software development process, there is huge demand for experienced software testers in software industries. Thus, you can enroll in Software testing training in Chennai @ FITA for bright career.
Why You Need Performance Testing:
Software testing is mainly done for three main purposes. First, testing is done to check whether the application meets its specified performance norms. For an instance, performance criteria will specify that a software/application musty handle 400 concurrent users. Secondly, it compares two software products to determine which one is performing better. Lately, performance testing is used to measure the configuration of an application under test. The most common examples of performance criteria would be insufficient memory leading to issues.
Goal of Performance Testing:
The whole process of software testing is carried out to accomplish four main goals:
- To calculate the rate of transaction or throughput
- To check the server response time, which is the instance taken by an application node to respond to the request made by other application.
- To determine the responsive time of the application
- To validate the performance specification and document as per test plan
Types of Software Performance Testing:
Software performance testing is classified into six types such load, stress, soak, spike, configuration and isolation tests.
Load test is implied to study the behavior of an application under actual load. It shows how an application will perform when imposed into actual load. Load testing is mainly done to determine response time, throughput rates and resource utilization rates.
Stress testing is used to determine the maximum limit of the software/application capacity and how it performance on the maximum loads. The main aim of this testing is identify bugs and other issues happen in maximum load conditions occur in real time. This test helps you to determine maximum load that given application can support.
Soak tests are carried out with the motive of validating how the application works under expected load. For instance, soak test can be carried out to check memory utilization, memory leaks and other performance related issues.
This test is performed to check whether a software/application has the potential to sustain the workload. This validation is carried out by increasing the end users by huge margin and accessing the overall performance.
Configuration and Isolation Tests:
Configuration testing is performed to measure impact of configuration changes to the elements of the application on the application performance and behavior. Isolation test is used to isolate the fault domain.
External Resource for software testing:
Setting up an environment for performance testing for several applications can be expensive and time consuming. HP LoadRunner is most popular automation testing tool used for performance testing. This tool provides precise information about performance and behavior of a software application or environment.
The quality of the application is very important in the software development life cycle. Thus, performance testing has become mandatory part in software development and deployment. Recruiters are looking for talented professionals who can handle LoadRunner automaton testing tool. LoadRunner Training in Chennai @ FITA will ensure huge career opportunity for freshers and experienced professionals in software testing domain.
