!2 Test the Link Alias syntax.
Aliases to links can be created using the !-[[tag][link]]-! syntax.
The tag is interpreted for markup syntax, so it can be italic, or bold, or an image, etc.  The link can be a relative or global wiki word, or it can be an http link.

----
!3 Test relative link alias
 * First create two sub pages.  One has a relative link to the other.
|Page creator.|
|Page name.|Page contents.|Page attributes.|valid?|
|!-SomePage.TargetPage-!|target page||true|
|!-SomePage.LinkPage-!|!-[[tag][TargetPage]]-!||true|
 * Then get the page with the relative link on it.
|Response Requester.|
|uri|valid?|
|!-SomePage.LinkPage-!|true|
 * Then make sure the relative link is properly constructed.
|Response Examiner.|
|type|pattern|matches?|value|
|contents|<a href=!-"SomePage.TargetPage"-!>tag</a>|true||
----
!3 Test global link alias
 * First create a sub page that has a global reference to another sub page.
|Page creator.|
|Page name.|Page contents.|Page attributes.|valid?|
|!-SomePage.GlobalLinkPage-!|!-[[tag][.SomePage.TargetPage]]-!||true|
 * Then fetch that page.
|Response Requester.|
|uri|valid?|
|!-SomePage.GlobalLinkPage-!|true|
 * Make sure the link is properly formed.
|Response Examiner.|
|type|pattern|matches?|value|
|contents|<a href=!-"SomePage.TargetPage"-!>tag</a>|true||
----
!3 Test variables get rendered in http link alias
 * First create a page with a variable and http link on it.
!|script|
|start|Page Builder|
|line|&bang;define HOST {localhost:8080}|
|line|!-[[tag][http://${HOST}/page]]-! works fine.|
|page|!-HttpLinkPage-!|

 * Fetch the page.
|Response Requester.|
|uri|valid?|
|!-HttpLinkPage-!|true|
 * Make sure the link is properly constructed.
|Response Examiner.|
|type|pattern|matches?|value|
|contents|<a href=!-"http://localhost:8080/page"-!>tag</a> works fine.|true||
----
!3 Test variables defined in parent page get rendered in http link alias on child pages
 * First define parent page with variable definition and child page with a http link which uses the variable.
|Page creator.|
|Page name.|Page contents.|Page attributes.|valid?|
|!-SomePage.ParentPage-!|!-!define HOST {localhost:8080}-!||true|
|!-SomePage.ParentPage.ChildPage-!|!-[[tag][http://${HOST}/page]]-! works fine.||true|

 * Fetch the page.
|Response Requester.|
|uri|valid?|
|!-SomePage.ParentPage.ChildPage-!|true|

 * Make sure the link is properly constructed.
|Response Examiner.|
|type|pattern|matches?|value|
|contents|<a href=!-"http://localhost:8080/page"-!>tag</a> works fine.|true||
-----
!3 Test expressions without variables in link alias
 * Create pages to refer to
|Page creator.|
|Page name.|Page contents.|Page attributes.|valid?|
|!-PageLink2-!|contents||true|
|!-PageLink4-!|contents||true|
|!-PageLink10-!|contents||true|

 * First create a page with a variables and http link on it.
|script|
|start|Page Builder|
|line|!-!define X {5}-!|
|line|!-!define Y (4)-!|
|line|!-!define EXPR (${=3+2-1=})-!|
|line|!-[[tag][PageLink${= 3 - 2 + 1 =}]]-! works fine.|
|line|!-[[tag][PageLink${EXPR}]]-! works too.|
|line|!-[[tag][PageLink${=${X}+${Y}+1=}]]-! works as well.|
|page|!-HttpExprPage-!|

 * Fetch the page.
|Response Requester.|
|uri|valid?|contents?|
|!-HttpExprPage-!|true||

 * Make sure the link is properly constructed.
|Response Examiner.|
|type|pattern|matches?|
|contents|<a href=!-"PageLink2"-!>tag</a> works fine.|true|
|contents|<a href=!-"PageLink4"-!>tag</a> works too.|true|
|contents|<a href=!-"PageLink10"-!>tag</a> works as well.|true|

!3 Test that links with query strings and fragments are handled properly.
 * Create a page hierarchy
|Page creator.|
|Page name.|Page contents.|Page attributes.|valid?|
|!-QueryPageRoot-!                  |!-!anchor QPLabel   -!||true|
|!-QueryPageRoot.TopPage-!          |!-!anchor QPTopLabel-!||true|

 * Create a page of query and fragment links...and a child
|script|
|start|Page Builder|
|line|!-[[tag1 ][TopPage?edit]]-! has query.|
|line|!-[[tag2 ][TopPage?edit#QPTopLabel]]-! has query and frag.|
|line|!-[[tag3 ][TopPage#QPTopLabel]]-! has fragment.|
|line|!-[[tag4 ][<QueryPageRoot.TopPage?edit]]-! back has query.|
|line|!-[[tag5 ][.QueryPageRoot.TopPage?edit]]-! root has query.|
|line|!-[[tag6 ][<QueryPageRoot.TopPage?edit#QPTopLabel]]-! back has query and frag.|
|line|!-[[tag7 ][<QueryPageRoot.TopPage#QPTopLabel]]-! back has fragment.|
|line|!-[[tag8 ][>ChildFrag?edit]]-! child has query.|
|line|!-[[tag9 ][>ChildFrag?edit#QPTopLabel]]-! child has query and frag.|
|line|!-[[tag10][>ChildFrag#QPTopLabel]]-! child has fragment.|
|page|!-QueryPageRoot.QueryFragmentLinks-!|

|Page creator.|
|Page name.|Page contents.|Page attributes.|valid?|
|!-QueryPageRoot.QueryFragmentLinks.ChildFrag-!|!-!anchor QPChild-!||true|

 * Fetch the page.
|Response Requester.|
|uri|valid?|contents?|
|!-QueryPageRoot.QueryFragmentLinks-!|true||

 * Make sure the query and fragments don't interfere with page paths.
|Response Examiner.|
|type|pattern|matches?|
|contents|<a href=!-"QueryPageRoot\.TopPage\?edit"-!>tag1 </a> has query.|true|
|contents|<a href=!-"QueryPageRoot\.TopPage\?edit#QPTopLabel"-!>tag2 </a> has query and frag.|true|
