Business description

Criterion : 5.4

Test : 5.4.1

Test description :

Does each data table (table tag) have a caption tag?

Level : Bronze

Technical description

Scope : page

Decision level : semidecidable

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. 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
MessageB : Check the nature of table without caption child
MessageC : Check the nature of table without caption child

Analysis

Not Applicable

Selections are empty (The page has no table tags that means that Set1 and Set2 are empty)

Failed

Test1 returns false

Passed

Test1 returns true and Set2 is empty

Pre-qualified:

on all other cases
