PdfExtensionAccessibilityTreeDumpTest

A PdfExtensionAccessibilityTreeDumpTest loads a PDF file, waits for it to load, then dumps the accessibility tree. More about accessibility tree dump tests at content/test/data/accessibility/readme.md.

Filters and directives

Please refer to content/test/data/accessibility/readme.md to see how to use filters. Supported filters and directives are:

  • [x] @<platform>-ALLOW:
  • [ ] @<platform>-ALLOW-EMPTY:
  • [ ] @<platform>-DENY:
  • [ ] @WAIT-FOR:

The PdfExtensionAccessibilityTreeDumpTest implementation of extra directives/filters is similar to the DumpAccessibilityTreeTest. If you need to support additional directives/filters, see /src/content/test/data/accessibility/readme.md to respect the same interface as the one used for HTML accessibility tree dump tests.

Implementation details for parsing extra directives in HTML can be found in DumpAccessibilityTestBase::ParseHtmlForExtraDirectives().
