Performance testing is the process to identify whether the program will have the ability to handle the high load, among other potential performance issues later on. As Wikipedia says, the principal purpose of the performance testing method is to determine the way the system performs in terms of responsiveness and stability under a particular workload.
Software Performance Testing Process
The performance testing methodology may fluctuate widely; nonetheless, the most crucial objective of the evaluations remains the same. It assists your applications to meet specific pre-defined performance standards.
Below is a generic software performance testing procedure:
Describe the Test Environment
Step one is the identification of their physical and production test environments along with the performance testing tools and resources available with the test group. A comprehensive understanding of the entire climate contributes to a more efficient evaluation design.
Identify Performance Acceptance Criteria
This measure includes the identification of their throughput, response times, and resource allocation. Moreover, it is also vital to judging the job success criteria out of these goals and limitations and, for instance, using performance tests to assess which combination of configuration settings will lead to the most desirable performance characteristics.
It is essential to plan performance evaluation data after a simulation of many different test users and, so, outline the metrics which will be accumulated.
Configure the Test Environment
This measure deals with the preparation of the evaluation environment before the execution phase. Aside from that, you need to arrange all of the necessary resources and tools in this phase.
Implement the Test Design
Depending on Your evaluation layout, build the operation evaluations.
Employ the Test
Run, track, and confirm your tests.
Now, as per your results, fine-tune and test again to assess whether there's an improvement or decrease in performance.
Software Performance Testing: Types and Tools
To be able to minimize risks and reduce costs, it's vital to identify the appropriate evaluation that must be applied to the software product. And for that to occur, it is crucial to get familiar with the gap in various performance evaluation types. In the following section, we'll go over the most popular varieties of performance testing and tools necessary to do them.
1. Load Testing
Load Testing is conducted to gauge the performance of a program under both average and peak problems. The objective of this Load and Performance Testing is to identify the bottlenecks in performance prior to going live with the program application.
If a software does not experience the Load Evaluation, the result can be as harmful as the crashing of this site at the peak moment. This wreck might have cost the company around $7,000,000. Customers took this problem to social media and whined about it.
It supports Load Testing by creating a high virtual user load from the cloud as well as locally. Moreover, it integrates with a significant number of third-party tools for monitoring, such as AppDynamics and Dynatrace. Additionally, it supports cellular and UI test scripts out of Selenium and Perfecto.
2. Stress Testing
Stress Testing is completed to assess the operation of the system once the number of consumers is increased beyond the limits of its specified conditions. Among those aims to carry out this test is to understand where degree the application is likely to crash.
Apart from this, this test also provides insight into the way in which the app crashes and the estimated time necessary to fix the solution after an accident. Unlike Load Testing, Stress Testing is performed out of the parameters of normal working conditions.
3. Soak Testing
Soak testing, also known as Endurance Testing, intends to evaluate the working of software under a standard workload over a protracted quantity of time. It seems at the stability and response time of the application. Soak testing would aim to identify system issues like memory leaks.
4. Spike Testing
SpikeTesting is a type of Performance testing that is performed by abruptly increasing or decreasing the load generated by a very large number of consumers. The main aim is to assess whether the operation will endure; the system will fail. Also, it will have the ability to manage dramatic fluctuations in load.
