如何将phpRack与phing集成以进行自动化测试？

For PHPUnit tag is supported in phing's build.xml. What to do if the automated tests use phpRack? i.e. extend phpRack_Test class

The phpRack docs say that phpRack can be integrated with phing like this:

<target name="phpRack" description="Validate all integration tests">
    <http-request
        url="http://example.com/phprack.php?suite"
        authUser="john"
        authPassword="jf7mF4"
        responseRegex="/PHPRACK SUITE: OK/"
        verbose="true"
        observerEvents="connect, receivedBody, disconnect"
    />
</target>

By making this phing task fail when the result doesn't contain "OK" your build will also fail.

I have no clue how you can store the resulting page with phing though.
