Class Harness

java.lang.Object

com.thoughtworks.xstream.tools.benchmark.Harness

public class Harness
extends Object

A simple harness for running benchmarks over object serialization products.

There are three dimensions that can be added:

• Product (e.g. DOM, SAX, XPP...)
• Metric (e.g. time taken, memory usage, output size...)
• Target (e.g. a small object, large object, list of objects...)

The Harness will then across every permutation of these (in order of product, metric, target), and write the results to a Reporter.

Example usage

 Harness harness = new Harness();

 // Compare speed of serialization/deserialization metrics...
 harness.addMetric(new SerializationSpeedMetric());
 harness.addMetric(new DeserializationSpeedMetric());

 // Using a simple String and a JTree instance...
 harness.addTarget(new StringTarget());
 harness.addTarget(new JTreeTarget());

 // Across XStream with different XML drivers.
 harness.addProduct(new XStreamDom());
 harness.addProduct(new XStreamXpp());
 harness.addProduct(new XStreamSax());

 // Now do it, and report the results as text to the console.
 harness.run(new TextReporter());
