 * Typically, the test code using the runner will programmatically create a build (e.g. by writing Gradle build files to a temporary space) to execute.
 * The build to execute is effectively specified by the {@link #withProjectDir(File)}} method.
 * It is a requirement that a project directory be set.

 * The {@link #withArguments(String...)} method allows the build arguments to be specified,

A property may be _mutable_, meaning that it has both a `get()` method and `set()` method:

include::sample[dir="snippets/providers/property/groovy",files="build.gradle[tags=prop-managed]"]

Or _read-only_, meaning that it has only a `get()` method.
The _read-only_ properties are _providers_:
