Test
Description
For each web page, does each identical link of type image have the same purpose and target?
Level
A
Technical description
Scope
Page
Decision level
Semi-Decidable
Algorithm
Selection
Set1
All the image links (see the definition of an image link in Rgaa 3.0) with a "href" attribute, without "title" attribute, without context (assuming the definition of a link context in Rgaa3.0) and with an identical link text.
Set2
All the image links with a "href" attribute, a not empty "title" attribute, without context and with an identical link text (combinaison of the link text and the "title" attribute text)
Set3
All the image links with a "href" attribute, with a context and with an identical link text (combinaison of the link text and the "title" attribute text if it exists)
Process
Test1
We check whether all the elements of Set1 have an identical "href" attribute.
For each element returning false in Test1, raise a MessageA.
Test2
We check whether all the elements of Set2 have an identical "href" attribute.
For each element returning false in Test2, raise a MessageA.
Test3
We check whether all the elements of Set3 have an identical "href" attribute.
For each element returning false in Test3, raise a MessageB.
MessageA
- code : IdenticalLinkWithDifferentTarget
- status: Failed
- parameter : text,
"href"attribute,"title", computed link text, tag name, snippet - present in source : yes
MessageB
- code : SuspectedIdenticalLinkWithDifferentTarget
- status: Pre-Qualified
- parameter : text,
"href"attribute,"title", computed link text, tag name, snippet - present in source : yes
Analysis
Not Applicable
The page has no group of image links with an identical link text (Set1, Set2 and Set3 are empty)
Failed
- At least one element of the Set1 has a
"href"attribute different from the others (Test1 returns false for at least one element) - At least one element of the Set2 has a
"href"attribute different from the others (Test2 returns false for at least one element)
Pre-Qualified
In all other cases
Notes
We assume here that the image links have only one child of type <img>, <object> or <canvas>
