The latest 10 open-source stress/load testing tools in linux
The load/stress testing tool can help you understand the execution of applications under load/pressure. It can expose problems and improve the performance. Therefore,
The following are ten free Web load/stress testing tools, you can know how much concurrency your server and your WEB application can withstand, and the performance of your website. I believe that the development team of the ticket booking website of the Beijing Organizing Committee does not know such a test tool.

software can also be used at this layer.At the network layer, network engineers can use packet detectors (such as tcpdump), network protocol analyzers (such as ethereal), and other tools (such as netstat, MRTG, ntop, MII-tool)
From the test point of view, all the activities described above are a white box method, which reviews and monitors the system from the inside out to the outside. After the measurement data is obtained and analyzed, the adjust
The three concepts of load testing, stress test, and performance test are often confusing and difficult to distinguish, this leads to incorrect understanding and incorrect use. There have been a lot of discussions before. The famous ones should be classified as two blogs of grig Gheorghiu's:
Performance vs. load vs. Stress
Performance Testing(Or multi-user concurrent performance testing ),
Capacity TestIt is a few aspects of performance testing, but the concept is easy to confuse. The following describes several concepts.
Summary of front-end unit testing and introduction of testing tools, and unit testing tools1. Why unit testing?
Correctness: The test can verify the correctness of the code, so you have a thorough understanding before going online.
Automation: Of course, manual tests can
scripts containing custom Protocols Written in powerful Jython and Clojure languages. The Grinder GUI console allows you to monitor and control multiple load syringes and automatically manage client connections and cookies, SSL, proxy awareness, and throttling connections.
The Grinder is free of charge under The BSD open source license.
TestNG is a testing

Website developers often need to check the compatibility of the website in various browsers to ensure that the work of the website works perfectly in all browsers. To this end, there are a lot of cross-browser testing
Summary of necessary development and testing tools for programmers, and summary of testing tools for programmersThe Network Monitoring Service was born in the age of Internet blowout. for Internet users, in just a few years, they have gone through a forum from browsing the Web pages with white background and black char

the user information of the previous node, and joins to the second layer of node running line program, This allows the data to be received from two nodes by means of a precision test oscilloscope (the login user ID and the request identity are consistent). And when multiple users access the distributed application at the same time, the data from different users will be automatically separated and routed to the corresponding oscilloscope and finally corresponding to the use case.Developer Test (
supports scripting (1.9.2 and above supports BeanShell). In the design phase, JMeter can act as an HTTP proxy (proxy) to record Ie/netscape HTTP requests, or log files of Apache and other webserver to reproduce HTTP traffic. When these HTTP client requests are logged, the test run can easily set the number of repetitions and concurrency (threads) to generate significant traffic. JMeter also provides visual components and reporting tools to show the p
Common Linux Network Tools: Http stress testing AB and linux stress testing
The full name of AB is Apache stress, which is a self-built Network stress testing tool of Apache. Compared with LR and JMeter, AB is the simplest and most common Http stress testing tool I know.

under heavy load. These are issues that you cannot find during the development process as a single user through the test system. Early implementation of the Load Test Plan helps to minimize exceptions during development.
In this article, we will introduce the testing method based on practical experience, but this is not to leave the traditional
Two confusing concepts:Load Testing: by gradually increasing the complexity of the system and testing its changes, we can see how much load the system can accept when the performance is met.
Stress Testing: by gradually increasing the complexity of the system and testing it
The testing, debugging, and performance testing tools that are readily available in linux are originally named test, debugging, and performance tools that come with linux, but they are not appropriate. for example, gdb mentioned in this article, many Linux distributions provide it, but after all it is not a necessary p
Platform-based software testing tools, often involving various roles, are most exposed to software test engineers and development engineers.

Ordinary users complain more and offer less, but most users of software testing tools are software test engineers and development engineers.
