Summary
This tests consists in checking the presence of a caption child node on the data <table> tags. Data <table> tags are characterized by HTML markers. When tables cannot be characterized, the test is applied but the result is semi-decidable.

Algorithm
Selection
Set1 (table tags identified as data table from html markers)
All the <table> tags with an "id" attribute or a "class" attribute or a "role" attribute that matches one of the values set by the user through the "DATA_TABLE_MARKER" parameter.
Set2 (table tags not identified as data table from html markers)
All the <table> tags that don't have an "id" attribute or a "class" attribute or a "role" attribute that matches one the values set by the use through the "PRESENTATION_TABLE_MARKER" parameter or the "DATA_TABLE_MARKER" parameter or the "COMPLEX_TABLE_MARKER" parameter. That means select all the <table> tags of the page when these parameters are empty.
Process
Test1 (only applied when the "DATA_TABLE_MARKER" parameter is not empty) :
For each element of Set1 (data tables identified by a html marker), test whether the node has a <caption> child node :
For each occurence of false-result of Test1, raise a MessageA
Test2 :
For each element of Set2 (tables not identified as data tables), test whether the node has a <caption> child node :
For each occurence of false-result of Test2, raise a MessageB
For each occurence of true-result of Test2, raise a MessageC
MessageA : Caption Missing on data tables
- code : CaptionMissing
- status: Failed
- parameter : Snippet
- present in source : yes
MessageB : Check the nature of table without caption child
- code : CheckNatureOfTableWithoutCaptionChildElement
- status: Pre-Qualified
- parameter : Snippet
- present in source : yes
MessageC : Check the nature of table without caption child
- code : CheckNatureOfTableWithCaptionChildElement
- status: Pre-Qualified
- parameter : Snippet
- present in source : yes
Analysis
Not Applicable
The page has no <table> tag (Set1 and Set2 are empty)
Failed
At least one data table has no <caption> child tag (Test1 returns false for at least one element)
Passed
All the tables of the page are identified as data tables and they all have a <caption> child tag (Test1 returns true and Set2 is empty)
Pre-qualified:
In all other cases
