Load and Performance Test Tools Pylot - Open source tool by Corey Goldberg for generating concurrent http loads. Define test cases in an XML file - specify requests - url, method, body/payload, etc - and verifications. Verification is by matching content to regular expressions and with HTTP status codes. HTTP and HTTPS (SSL) support. Monitor and execute test suites from GUI (wxPython), and adjust load, number of agents, request intervals, rampup time, test duration. Real-time stats and error reporting are displayed. JCrawler - An open-source stress-testing tool for web apps; includes crawling/exploratory features. User can give JCrawler a set of starting URLs and it will begin crawling from that point onwards, going through any URLs it can find on its way and generating load on the web application. Load parameters (hits/sec) are configurable via central XML file; fires up as many threads as needed to keep load constant; includes self-testing unit tests. Handles http redirects and cookies; platform independent. vPerformer - Performance and load testing tool from Verisium Inc. to assess the performance and scalability of web apps. Use recorded scripts or customized scripts using Javascript. Targeted platforms: Windows Curl-Loader - Open-source tool written in 'C', simulating application load and behavior of tens of thousand HTTP/HTTPS and FTP/FTPS clients, each with its own source IP- address. In contrast to other tools curl-loader is using real C-written client protocol stacks, namely, HTTP and FTP stacks of libcurl and TLS/SSL of openssl. Activities of each virtual client are logged and collected statistics include information about: resolving, connection establishment, sending of requests, receiving responses, headers and data received/sent, errors from network, TLS/SSL and application (HTTP, FTP) level events and errors.
