Test

5.7.1

Description

Does each header cell (th tag) applied to the whole row or to the whole column have a unique id attribute or a scope attribute?

Level

A

Technical description

Scope

Page

Decision level

Semi-Decidable

Algorithm

Selection

Set1 (table tags identified as data or complex 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 or the "COMPLEX_TABLE_MARKER" parameter AND with <th> child tags.

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 user through the "PRESENTATION_TABLE_MARKER" parameter or the "DATA_TABLE_MARKER" parameter or the "COMPLEX_TABLE_MARKER" parameter AND with <th> child tags.

That means select all the <table> tags of the page when these parameters are empty.

Process

Test1

For each occurence of Set1, raise a MessageA

Test2

For each occurence of Set2, raise a MessageB

MessageA : Check the definition of headers for data tables
MessageB : Check the nature of table and the definition of headers for data tables

Analysis

Not Applicable

The page has no <table> tag with <th> child tags or only tables identified as presentation table (Set1 AND Set2 are empty)

Pre-qualified

In all other cases

Notes

We only detect the elements of the scope of the test to determine whether the test is applicable.

Complex tables are seen as a subset of data tables. That's tables identified as complex tables are added to the set of identified data tables.
