What is Performance Testing And Its Process?
Performance testing determines how a system performs in terms of responsiveness and stability under a given workload in software quality assurance. Other quality features of the system, such as scalability, dependability, and resource utilization, can also be investigated, measured, validated, or verified with it.
Attributes of Software Performance Testing:
- Speed: It determines whether or not the software product reacts quickly.
- Scalability: It establishes the maximum load that a software program can manage at any one time.
- Stability: It determines if the software product is stable under different workloads.
- Reliability: It determines whether or not a piece of software is secure.
Process of Software Performance Testing
The actual process can vary substantially because software performance testing can be done with different sorts of data. A general procedure, on the other hand, can look like this:
- Determine the testing environment: Identify the setting where the testing will take place. This applies to both test and production settings and testing tools.
- Defining and identifying acceptable performance criteria: This should include performance objectives and metric restrictions.
- Plan and create performance testing: All potential use cases should be tested. Create test cases based on key performance indicators.
- Setting up and running a test design environment: Set aside resources to prepare the test environment, and then work on putting it in place.
- The test is in progress: The exam should also be monitored.
- Analyzing and testing again: Examine the results. Retest after any fine-tuning to see if performance has improved or decreased.
Performance Testing Objectives
The complete process of software performance testing is carried out to achieve four objectives:
- To determine the transaction throughput or rate.
To calculate the server response time, which is the time it takes an application node to respond to a request from another node. - To calculate the server response time, which is the time it takes an application node to respond to a request from another node.
- To identify and document the performance specifications in the test plan.
Tools for Software Performance Testing
There are many different types of software performance testing tools on the market. The following are a few examples of performance testing tools:
- HP LoadRunner: One of the most widely used software performance testing tools available today. This program can simulate hundreds of thousands of users, putting applications under real-world stress to see how they react. A virtual user generator is included in Loadrunner, which simulates the activities of real human users.
- NeoLoad: It is a Neotys product that conducts load and stress assessments for online and mobile applications and is specifically intended for DevOps and continuous delivery. An IT team can use the tool to keep tabs on the web, database, and application servers. NeoLoad can simulate millions of users and do testing independently or in the cloud.
. Jmeter: One of the most used load testing tools for web and application servers.
