XStream: A simple library to serialize objects to XML and back again

XStream is a simple library to serialize objects to XML and back again.

• Ease of use. A high level facade is supplied that simplifies common use cases.

• No mappings required. Most objects can be serialized without need for specifying mappings.
• Performance. Speed and low memory footprint are a crucial part of the design, making it suitable for large object graphs or systems with high message throughput.
• Clean XML. No information is duplicated that can be obtained via reflection. This results in XML that is easier to read for humans and more compact than native Java serialization.
• Requires no modifications to objects. Serializes internal fields, including private and final. Supports non-public and inner classes. Classes are not required to have default constructor.
• Full object graph support. Duplicate references encountered in the object-model will be maintained. Supports circular references.
• Integrates with other XML APIs. By implementing an interface, XStream can serialize directly to/from any tree structure (not just XML).
• Customizable conversion stategies. Strategies can be registered allowing customization of how particular types are represented as XML.
• Error messages. When an exception occurs due to malformed XML, detailed diagnostics are provided to help isolate and fix the problem.

Sahi: An automation and testing tool for web applications, with the facility to record and playback scripts

Sahi is an automation and testing tool for web applications, with the facility to record and playback scripts. Features include, in-browser controls, text based scripts, ant support for playback of suites of tests, and multi threaded playback. It supports HTTP and HTTPS.

This makes the tool independent of the Web site or Web application.
