Create a page tree to be imported.
!|Page creator.                                     |
|Page name.                   |Page contents.|valid?|

|ImportedRoot.PageOne         |page one      |true  |
|ImportedRoot.PageOne.ChildOne|child one     |true  |
|ImportedRoot.PageTwo         |page two      |true  |

Create an importing page.
!|Page creator.                     |
|Page name.   |Page contents.|valid?|
|ImportingPage|!contents     |true  |

This !-ImportingPage-! will now import the !-ImportingRoot-! page created above.
!|Response Requester.                                                                          |
|uri                                                                                    |valid?|
|ImportingPage?responder=import&remoteUrl=http://localhost:${INTERNAL_PORT}/ImportedRoot&nochunk=true|true  |

We see all 3 pages imported.
!|Response Examiner                     |
|type    |pattern              |matches?|
|contents|3 pages were imported|true    |

Sleep a bit so that the last modification time actually changes.
|Sleep|1000|

Importing again will show that no pages were imported since none had changed.

|ImportedRoot.PageOne?edit|3.141592     |303    |

Importing again will shows only 1 page imported, 2 unchanged.
