web load testing tools

Overview With the development of Web application technology and the rapid popularization of Web applications, the performance and service quality of web system becomes more and more important. Performance testing plays a more and more important role in the quality assurance of software. Performance test is to test the

"It's one thing to get your Web application to do what you want to do, and getting them to do it quickly and efficiently is often another matter." ” In this article I will briefly discuss the "performance of Web Applications" issues, mainly some basic concepts and tools, which is a trigger! Note that these contents are also applicable to the Java EE application.

With the increasing popularity of the Internet, there are more and more large applications based on the B/S structure. It is becoming increasingly urgent to test these applications. Many testers wrote to me about how to perform the B/S test. Due to busy work, the question raised by me was a headache, there is no overall overview of the Web testing process. We hope that this article will help you understand

not familiar with programming languages to master.Apache jmeter clicks: 2672 Apache jmeter is a 100% pure Java Desktop running program designed specifically for running and server load testing. It was originally designed for Web/HTTP testing, but it has been extended to support a variety of Test Modules. It is shipped

Powerful tools for parsing html and collecting web pages, and powerful tools for collecting html data HtmlAgilityPack is A. Net-based, third-party free open-source micro-class library, mainly used to parse html documents on the server side (in B/S structure programs, the client can use Javascript to parse html ). As of this article, the latest version of HtmlAgil

The earliest time is to do functional testing, the Web is their own manual click to see if there is no problem, no system for testing, let alone automated testing, it is a piece of the past, it is because of this, a lot of problems are out of the way, which is as a test personnel of a major dereliction of duty, a bitte

repetitions. The URL file is a text, each line is a URL, it will be randomly accessed from the inside.Iv. Http_loadThe program is very small, after decompression is less than 100KThe http_load runs in parallel multiplexing to test the throughput and load of the Web server. However, unlike most stress testing tools, it

time to support complex programming. Maybe today we only need to search for a simple string on the web page, so the string function provided by the tool is enough to use, but tomorrow we may have to traverse all the elements on the web page, so we need a powerful HTML Parser. Never tell me that this tool does not support HTML parsing. Unfortunately, many tens of thousands of

method. 1. Link Testing: links are a major feature of Web application systems. They are the main means of switching between pages and guiding users to access pages with unknown addresses. Link testing can be divided into three aspects: 1) test whether all links are actually linked to the link page as instructed; 2) test whether the linked page exists; 3) ensure

If you are using Secure Sockets Layer (SSL) Over HTTP to encrypt user data and want to program your web application, you will find that this technology is not widely known. In this topic this month, I will demonstrate how to create an SSL test server, write test automation code, and verify it through a simple and representative web application.The Microsoft. NET environment provides powerful

#fall 5 5 times in a row, the heartbeat is not considered a server unavailableExperiment (II)Experimental purpose: Haproxy do lb load Balancing cluster, let a client's multiple access requests are haproxy distributed to the back end of the same server (only applicable to the Web cluster).Experimental environment: Ibid.1. Modify the master configuration file, the cookie ServerID Insert indirect nocache to in

different startup parameters ". During the Transaction test, multiple threads can only be enabled on multiple machines. The main parameters of YCSB include the load volume, operation type and proportion, and the distribution of operation target records. The parameters of YCSB can be manually configured as needed, making it easy to apply.Conclusion Good Web performance analysis
