* Target preparer that fetches classpath relevant artifacts for a test in a 'reentrant' manner.
|
|
*
|
|
* <p>The preparer will fetch all <b>BOOTCLASSPATH</b>, <b>SYSTEMSERVERCLASSPATH</b> and shared
|
|
* libraries from the device, parse their contents and dump the classnames into a temporary
|
|
* directory.</p>
|
|
*
|
|
* <p>Additionally, the preparer <i>can</i> fetch, parse and dump data for module specific artifacts
|
|
* (i.e. apk-in-apex) if specified.</p>
|
|
*
|
|
* <p>Nested runs of the artifact fetcher (i.e. in the case of a top-level test config xml and a
|
|
* child test xml) will only fetch non-common elements, and remove temporary class dumps fetched
|
|
* during that particular preparer run.</p>
|
|
*
|
|
* <p>Each module's conformance framework test config xml must run the preparer (with module
|
|
* specific parameters) before the entrypoint test jar, and the top-level conformance framework
|
|
* config xml must also run it before any other module xml.</p>
|
|
*
|
|
* <p>The upshot is that when running all conformance framework tests for all modules, the shared
|
|
* artifacts are fetched and processed only once.</p>
