Asqatasun v4 - AccessiWeb 2.2 - Rule 13.6.1
Summary
This test consists in checking whether each downloadable file provide information about its format
Business description
Criterion : 13.6
Test : 13.6.1
Test description :
On each Web page, does each file to download via a link or a form have information about its format (except in special cases)?
Level : Bronze
Technical description
Scope : page
Decision level : semidecidable
Algorithm
Selection
Set1 : All the <a>
tags with an href
attribute (a[href]
)
Set2: All the elements from Set1 with an href
attribute that does not contain a fragment (presence of the hash sign (#))
Set3 : All the elements from Set2 that have a proper extension (no parameters, a path after the domain that contains a "." character)
Set4 : All the <form>
tags (form)
Process
Test1
For each element of Set3, we check whether the content of the href
attribute of the link ends with an extension that belongs to the downloadable document extension list.
For each element returning true in Test1, raise a Message1
Test2
IF Test1 returns false, we check whether the size of Set2 is equals to size of Set3. In other words, we verify that all the links of the page have a well-defined extension.
If Test2 returns false (some links have no extension on the page), raise a Message2.
Test3
If Test2 returns true (all the links have a well-defined extension that belongs to the web content extension list), we check whether Set4 is empty (the page contains forms that may lead to a downloadable document).
If Test3 returns false (some form are found on the page), raise a Message3.
Message1: File To Download Detected, check format
- code : FileToDownloadDetectedCheckFormat
- status: NMI
- parameter : href title attribute, title attribute, snippet
- present in source : yes
Message2: Check manually links without extension
- code : CheckManuallyLinkWithoutExtension_AW22-13061
- status: NMI
- present in source : no
Message3: Check downloadable document from form
- code : CheckDownloadableDocumentFromForm_AW22-13061
- status: NMI
- present in source : no
Analysis
NA
- Set2 is empty (the page has no link that are no anchor)
- Test3 returns true (all the links of the page have a well-defined extension AND all the extension are of web content type AND the page has no form)
NMI
In all other cases
Notes
We assume that a targetted document (pointed by the "href" attribute of the link) can be characterized by its extension.
