Software performance testing is the practice of ascertaining whether a given program has the capacity to perform required scalability and responsiveness below a specified workload. Responsiveness refers to the capability of a given application to satisfy pre-determined goals for throughput, while scalability is the variety of activities processed within a given time. Performing this kind of testing is a crucial element when discovering the standard of a given application.

First, testing is done in order to ascertain whether the program meets the specified performance standards. For example, performance standards may specify that a request must have the ability to handle 500 concurrent users. Second, it compares two or more applications with the purpose of determining which you can perform far better.

For example, say your application needs a tool to export accounts. You can compare tools to see which tool's functionality can best handle the export demands. Lastly, performance testing is done to assess the components or configuration of a certain application that is responsible for the inadequate performance of the application. A frequent example of this will be insufficient memory resulting in performance bottlenecks.

The whole process of software performance testing is done to accomplish a set of four goals:

To Find out the throughput or the speed of this transaction.
To determine the server response time, that's the time obtained by a given program node to supply a reply to a request made by a different node.
To determine the reaction time of this render, which requires the inclusion of operational test scripts in the test scenario.
To determine the functional specifications and record them in the test program.

Following Are The Types of Software Performance Tests

There are significant kinds of software performance testing, including load, stress, soak spike, configuration, and isolation evaluations.

Load Testing

Load testing is utilized to study the behavior of the application under given loads. Additionally, it reveals how an application will operate when the vast majority of its customers are logged in. Load testing is principally performed to measure response times, resource usage amounts, and throughput rates.

Stress Testing

A stress test is done to ascertain the upper limit of the application capacity and how the application performs whenever the current load exceeds the anticipated maximum. The primary focus of doing testing is to discover application bugs that happen in high load conditions. This test determines the maximum load which a given application can support.

Soak Testing

Soak tests are done to determine the way the program endures beneath a constant expected load. For instance, a soak test could be performed to monitor memory usage and detect memory leaks and other performance issues that could happen. The aim of doing this type of assessment is to ascertain the application's performance in continual use.

Spike testing

Spike testing is done to determine whether a specified program has the capability to prolong the workload. The test is accomplished by raising the number of end-users by a large amount and analyzing the operation of the program overall.

While Microsoft states that configuration and isolation testing is useful, performing these tests is typically uncommon. Configuration testing is done to determine the impacts of configuration changes to components of this program on the application's behavior and performance. Isolation testing is done to isolate the error domain name.
