This program was written to help test the Open Projects dancer-ircd. It simulates client activity by selecting random servers to connect to and random actions out of a list. It can handle hundreds of simultaneous connections, and can replay a log file of what it has previously done in order to help isolate the actions which cause the daemon to have problems, using methods such as binary chops. Please note that although at this point code is only written to test ircds, it is hoped that this will be extended in the future to other types of daemons.
RUBiS is an auction site modeled after eBay.com used to benchmark e-commerce Web site technologies. It is currently used to evaluate design patterns, application servers, and communication layers scalability. Several implementations using PHP, Servlets, Enterprise JavaBeans (EB BMP, EB CMP, MDB, SB, EJB 2.0 CMP, Session Façade, etc.) are already available and new versions for JDO and .Net are currently developed.
Tsung is a distributed load testing tool. It is protocol-independent and can currently be used to stress HTTP, WebDAV, PostgreSQL, MySQL, LDAP, AMQP, and XMPP/Jabber servers. It simulates user behavior using an XML description file, reports many measurements in real time (statistics can be customized with transactions, and graphics generated using gnuplot). For HTTP, it supports 1.0 and 1.1, has a proxy mode to record sessions, supports GET, POST, PUT, and DELETE methods, cookies, and basic/digest authentication. It also has support for SSL, WebSocket, and BOSH.
SLAMD is a Java application designed for stress testing and performance analysis of network-based applications. Although it was originally designed for benchmarking directory servers, it is actually very flexible and can be used to test applications using a wide range of protocols like LDAP, HTTP, POP, IMAP, and SMTP, and can also interact with relational databases using JDBC. In addition, it provides a Java-based API for developing custom workloads, and a scripting engine and record and playback tools that may also be used in the load generation process.
FunkLoad is a functional and load Web tester whose main use cases are functional testing of Web projects (and thus regression testing as well), performance testing, load testing (such as volume testing or longevity testing), and stress testing. It can also be used to write Web agents to script any Web repetitive task.
