A stress testing tool (also known as a load testing tool) is a software tool that simulates various high-load situations to test the performance and stability of an application, website, or server. The purpose of stress testing is to understand whether the system can work normally under the condition of increased load, identify the performance bottleneck of the system, and improve the scalability and performance of the system.
The main functions of stress testing tools include simulating a large number of users accessing an application at the same time, generating high load to test the responsiveness of the system, detecting bottlenecks and causes of bottlenecks in the system, collecting performance indicators, and analyzing test results, etc.
The main scenarios for using stress testing tools include:
-
Stress test the system before going live to ensure that the system can withstand the expected load.
-
Perform a stress test before a system update or upgrade to check whether the performance has improved or decreased after the update.
-
Conduct stress tests during peak periods to evaluate system performance and availability during peak periods.
-
Test different scenarios, such as simulating concurrent user access, simulating random data generation and access, etc.
Common pressure measurement tools include Apache JMeter, Gatling, LoadRunner, Locust, etc. With the continuous development of Internet technology, stress testing tools have become standard tools for performance testing of applications, websites, and servers.
1. LoadTestToolbox is a lightweight stress testing tool
1. What is LoadTestToolbox
LoadTestToolbox is a lightweight stress testing tool developed in C# and based on .NET 6 version. Compared with other stress testing tools, LoadTestToolbox is very easy to install and use.
It supports a variety of protocols, such as HTTP/HTTPS, FTP, SMTP, POP3, etc., and can simulate a variety of different load conditions, such as high concurrency, high traffic, high pressure, etc., to test the performance stability and reliability of the system under different loads. LoadTestToolbox also provides several practical tools, such as automatic generation of test data, real-time monitoring and analysis of performance data, etc.

2.LoadTestToolbox use
.NET global tool installation, execute the following command
dotnet tool install --global LoadTestToolbox
LoadTestToolbox currently contains three tools, drill (drill), hammer (hammer), nailgun (nail gun):
1. Drill bit
Drill can be used to test the long-term stability of the application by making continuous requests at intervals over a longer period of time.
ltt drill --url https://www.baidu.com/ --rps 100 --duration 10 --filename chart.png
In the above command, LoadTestToolbox will make 100 requests per second (at consistent 20ms intervals) for 10 seconds to www.baidu.com.
2. Hammer
Hammer can test the performance of the interface by specifying a range of concurrent requests, and return the average response time of each request.
3. Nailgun
Nailgun can initiate a large number of instant requests to the specified interface to test the interface performance.

Summarize
The LoadTestToolbox pressure testing tool is still very simple to use, and can help developers and operation and maintenance personnel discover and solve performance problems in applications, improve system capacity and stability, and provide more reliable services for customers and businesses.
