What Tools Are Used For Load And Performance Testing?

Modern IT products require high performance and reliability, which makes performance testing an important part of development. It allows businesses to determine how systems cope with a large number of users, requests, or data. Among the popular tools, the JMeter cloud testing tool stands out, with its wide capabilities for load modeling and performance analysis. In this article, we will consider the main tools that help to effectively conduct such tests, including JMeter API Testing and others.

What Is The Purpose of Load And Performance Testing?

Load and performance testing of software determines the resource capabilities of digital platforms under standard and increased loads. If the website of an online store, marketplace, or media portal freezes when the user flow increases or new data is loaded, the response speed to actions decreases, the platform works unstably under normal load, etc., then the application requires testing.

Mandatory test trials are carried out before launching a digital portal in order to detect possible problems at the initial stage. During the work, the site should also be monitored to track any changes (traffic volume, code modification (reworking), web host configuration, adding content, etc.) that may affect the productivity of the product

Types of Performance Testing

Within the framework of performance testing, software is tested in several directions:

• Load testing reveals how software functions during an increase in workload in the current time period. To assess the capacity of a web resource, specialists increase the number of resource visitors, and the number of parallel transactions, change the course of the workflow, etc. During such a one-time impact, they track how the response speed, resource throughput, etc. change. The identified weak points are corrected.

• Endurance testing is carried out to study the behavior of a web site under long-term fixed loads. The main efficiency parameters are revealed: memory loss and lack of memory, analysis of throughput characteristics, and the response rate of the system (how these values ​​change during long-term use).

• Spike testing. This test measures the capabilities of the software during a sudden, strong load jump. A sharp change in load can be observed, for example, when modeling users (when the system adapts to the individual needs of each site visitor). Spike testing determines how fast and how many times the software can handle an extreme situation without failure.

• Stress resistance monitoring. The task here is to find out how the software works under high traffic. To check this, the number of visitors to the resource and the volume of transactions are increased many times. Specialists monitor problems in the system and the process of its recovery. The critical point is determined using hardware capabilities: processor, memory size, disk space, etc.). Stress resistance testing is usually carried out in anticipation of some major online events, for example, before an online conference with a large number of participants or “Black Friday” on the marketplace.

• Scalability testing. This test measures how the efficiency of the software decreases or increases during a gradual increase in load values.

Testing Tools

The modern IT market offers dozens of tools for testing on a free and commercial basis. Let's look at the best tools for load testing.

Apache JMeter

Apache JMeter has been around for over 20 years. The system is very popular among users, some testing platforms use Apache as an engine. Tool capabilities:

1. The program is free and has an open source code.
2. Apache JMeter checks the production of dynamic and static sites and simulates increased impact on one server or group.
3. JMeter is a popular alternative to commercial platforms, it solves most problems.
4. The cross-platform system is developed in Java, it is easy to use and does not require complex infrastructure to conduct tests.
5. Compared to other platforms, the program has a clear interface with fewer test scenarios.
6. Simple charts and graphs allow you to easily analyze statistical data.
7. Apache JMeter is compatible with a large number of load injectors that can be controlled from a single controller.
8. The tool works with HTTP, HTTPS, SOAP, XML, FTP, etc.
9. To perform special tasks, you can write your own extended version or use numerous ready-made plugins.

WebLOAD

It is one of the first testing programs, created in the late 90s. The enterprise-level WebLoad system can simulate several thousand visitors at a time. Among the advantages of this tool:

1. Performs load and continuous testing of websites, in addition, it can test the operation of the cloud and more.
2. The system receives a load from a cloud repository and user computers.
3. Recording and adjustment of test scenarios are carried out through the IDE software.
4. A proxy-based recorder records all your actions over HTTP and creates tests in JavaScript.
5. The WebLOAD performance testing system provides performance analytics, which can be used to identify program weaknesses.
6. Integration with Jenkins (to ensure continuous software integration), Selenium (to automate web browser operation), and other programs.

LoadUI Pro

LoadUI Pro is a load testing tool created in 2011. Among the advantages of the tool:

1. The program is written in the following languages: Java, Javafx, and Groovy.
2. The tool is focused on web resources with operating systems: Windows, Linux, and Mac OS.
3. It works with HTTP, SOAP, REST, XML Schema, JSON, JSON Schema, and API Blueprint.
4. The tool creates, manages, and performs tests of databases, microservices, and REST & SOAP APIs.
5. LoadUI Pro users test APIs for productivity, responsiveness, and scalability.
6. The tool runs on a cloud service, so users do not have problems with maintenance. It also uses the client's computing resources.
7. You can run several test loads at the same time to understand how different diagnostics combine and, ultimately, affect the efficiency of the API.
8. Reusing existing tests saves time.
9. You can expand the functionality by adding third-party plugins.

Final Thoughts

The choice of performance testing tools plays a key role in the successful operation of IT products. Solutions such as the JMeter cloud load testing tool provide powerful tools for simulating real-world load scenarios.
