Version 1.5

  • Abstracted out the concept of the Sampler, SamplerController, and TestSample. A Sampler represents code that understands a protocol (such as HTTP, or FTP, RMI, SMTP, etc..). It is the code that actually makes the connection to whatever is being tested. A SamplerController represents code that understands how to organize and run a group of test samples. It is what binds together a Sampler and it's test samples and runs them. A TestSample represents code that understands how to gather information from the user about a particular test. For a website, it would represent a URL and any information to be sent with the URL.
  • The UI has been updated to make entering test samples more convenient.
  • Thread groups have been added, allowing a user to setup multiple test to run concurrently, and to allow sharing of test samples between those tests.
  • It is now possible to save and load test samples.
