Peach 2.1 – Mutator Hints

This is the first in several articles covering some of the new features in Peach 2.1 BETA3. In this article I will cover the new <Hint> element. This element was added to allow metadata that can be used by different mutators to be added to the data model. For example, consider this data model:

 <DataModel name="FilenameParameter">
  <String name="Filename" value="c:\path\file.bin" />
</DataModel>

The Filename string element is a prime candidate for a hint indicating that not only is it a string, it is also a filename. The following is our changed data model that includes a hint:


	Miss Pettigrew Lives for a Day move

	The Bridge to Nowhere full movie



<DataModel name="FilenameParameter">
  <String name="Filename" value="c:\path\file.bin">
    <Hint name="type" value="filename" />
  </String>
</DataModel>

Multiple Hints are allowed per data element. The current set of mutators included with Peach only understand the following hints:

Name	Value	Description
type	path	Indicates a path name
	filename	Indicates a filename w/path.
	xml	Indicates value is XML. Causes the inclusion of the W3C parser tests
	hostname	Indicates value is a hostname.
