This is a simple end to end Web Service Testing library to test wide variety of web service. It supports hierarchy of test cases and test steps with wiring of request response objects using templated variable replacement. The test steps can be Web Service or DB call out of the box with capability to extend to other test steps. The DB steps are for data setup and assertion of values from the DB.

There is a newer version: 24.12.04.1
