Testing is an essential part in the software engineering process. Frameworks and tools help with the different testing steps like unit-testing, funcional testing, system testing, etc.
When it comes to testing web applications and/or web services a crucial part is load- and performance-testing. This means simulating situations where lots of users fire lots of requests and testing if the application still ensures correctness and reasonable time-performance.
A tool to easily simulate parallel user requests is wanted.
