Process
Test1

empty
For each element returning false in Test1, raise a MessageA

only contain non alphanumerical characters.
For each element returning false in Test2, raise a MessageB

doesn't belong to the text link blacklist.
For each element returning false in Test3, raise a MessageB
Test4
For each element of Set2, we check whether the "title" attribute is not
striclty identical to the link text.
For each element returning false in Test4, raise a MessageC

For each element of Set2, we check whether the "title" attribute
contains the link text and more.

Analysis
Not Applicable
The page has no clickable area (Set2 is empty)
Failed
- At least one clickable area has an empty title attribute (Test1 returns false for at least one element)
- At least one clickable area has title attribute only composed of non alphanumerical characters (Test2 returns false for at least one element)
- At least one clickable area a title attribute which is blacklisted (Test3 returns false for at least one element)
Pre-qualified
In all other cases
Notes
-
We assume here that the textual alternative of the area corresponds to the link text.
-
Definition of not-pertinent link title attribute :
A link title attribute is regarded as not-pertinent in the following cases :
- the
"title"attribute is empty - the
"title"attribute is blacklisted (regarding the LinkTextBlacklist nomenclature) -
the
"title"attribute only contains not alphanumerics characters -
Due to the "Note 1" of the definition of a link title, a
"title"attribute identical to the text link is seen as suspected passed.
