The modern era of IT has seen an overwhelming evolution of theÂ Software TestingÂ industry giving way to greener pastures. Thus it becomes very important to ensure the effective performance of the software application. Through the medium of this â€śPerformance Testing Tutorialâ€ť, I will be providing you in-depth knowledge about performance testing fundamentals along with the details on a load testing tool known as JMeter.
Below topics are covered in this article.
You may also go through this recording of software testing tutorial where ourÂ Software Testing TrainingÂ experts have explained the concepts in depth.
Performance Testing is a type of software testing that ensures that the software applications will perform well under their expected workload.Â It is essential to verify whether the product meets the expected or required performance level.Â Performance testing measures the quality attributes of the system, such as scalability, reliability and resource usage.
Now that you know what is performance testing, let’s see why you need performance testing.
Performance Testing provides information about their application regarding speed, stability, and scalability. More importantly, it uncovers what needs to be improved before the product goes to market. Without that, software might suffer from issues such as: running slow while several users use it simultaneously, inconsistencies across different operating systems and poor usability.
Performance testing determines whether their software meets speed, scalability, and stability requirements under expected workloads. Applications that are sent to market with poor performance metrics due to nonexistent or poor performance testing are likely to gain a bad reputation and fail to meet expected sales goals. These are a few of the reasons that depict the need for performance testing.
Now let’s dive deeper into this Performance testing tutorial article and see its different types.
Below image shows different types of performance testing.
Let’s have a look at the details of its various types in depth.
Now that you have gained some insights into the fundamentals of performance testing, let’s move further and understand the working and steps involved in the performance testing process.
The below infographic depicts the steps involved in the performance testing process. Let’s dive deeper and understand each of these steps in detail:
Identify the hardware, software, network configurations and tools available for testing.Â Performance testing environment optionsÂ include:
In addition to determining metrics such as response time, throughput and constraints, determine what are the success criteria for performance testing.
Determine performance test scenarios that take into account user variability, test data, and target metrics. This will basically create one or two models.
You need to prepare the elements of the test environment and instruments needed to monitor resources.
Develop and implement the tests for execution.
The last step is to analyze the data and share the findings. Here, you must run the performance tests again using the same as well as different parameters.
So, this was all about Performance Testing process. Now let’s know what are the test metrics or parameters for performance testing.
Now letâ€™s move ahead with our â€śPerformance Testing Tutorialâ€ť and find out some of the best tools used for performance testing.
Performance testing is significant in real time, particularly from a point of view of customer satisfaction. There are various performance testing tools available, such as:
Apache JMeter is a tool used for testing, analyzing and measuring the performance of different software services and products. It is one of the pure Java open source software used for testing Web Application or FTP application.
It is mainly used to execute performance testing, load testing and functional testing of web applications. JMeter can also simulate a heavy load on a server by creating tons of virtual concurrent users to a web server.
Letâ€™s take a look at the different steps performed by JMeter during testing:
