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
