Internal MathML tests

The web-platform-tests Project provides MathML tests for the MathML Core specification. This directory contains tests for MathML3 features implemented in Gecko or for Gecko-specific behaviors that are not described in any specification:

• disabled/: Tests for MathML handling when support is disabled. This is

mostly used for Tor browser's "high security" mode, see bug 1173199.

• fonts: font-related tests, such as OpenType features not handled yet in

MathML Core or other Gecko-specific behavior.

• mathml-console-messages.html: Tests for Gecko-specific console warning and

error messages triggered by MathML markup.

• mathspaces_names: Tests for

MathML3 namedspaces which are removed from MathML Core. See bug 1793549.

• mathvariant: Tests for the

mathvariant attribute, which is reduced to the case <mi mathvariant="normal"> in MathML Core. See bug 1821980.

• mpadded: Tests for some

mpadded features, which are not in the initial version of MathML Core.

• menclose: Tests for the

menclose element, which is not in the initial version of MathML Core. See issue 216.

• mo-accent: Tests for the

mo@accent attribute, and the corresponding accent property from the dictionary, which are removed from MathML Core. See bug 1790548 and bug 1636428.

• negative-lengths: Tests for negative lengths, for which support or

interpretation is unclear in current version of MathML Core. See issue 132.

• operator-stretching: Tests for operator stretching, using Gecko-specific

methods that are not part of the current version of MathML Core.

• rtl: Tests for RTL MathML, for aspects not completely defined in

MathML Core or for which we use things like scale transform for mirroring. See issue 67.

• scripts: Tests for MathML scripted elements, for Gecko features

that are not defined in MathML Core or in contradiction with the spec.

• tables: Tests for

table features that are in the initial version of MathML Core. See issue 125.

• whitespace-trimming: Tests for

whitespace trimming in token elements which is not described in the initial version of MathML Core. See issue 149.

• zoom: Tests to check MathML rendering at different zoom levels.
