CSS Writing Modes Module Level 3 CR Test Suite

This is a Development version of the CSS Writing Modes Module Level 3 CR Test Suite.

You can provide test data or review the testing results for this test suite:

Some tests in the test suite may contain errors. Please check the latest version of the CSS Writing Modes 3 specification and its errata before assuming a failure is due to an implementation bug and not a test suite bug.

In time we hope to correct all errors and extend this test suite to cover all of CSS Writing Modes 3. Your help is welcome in this effort. The appropriate mailing list for submitting tests and bug reports is public-css-testsuite@w3.org.

To report bugs or feedback about a specific test file, search for the filename (without extension) in web-platform-tests issues, and file a new issue if necessary with suggested label "wg-css". More information on the contribution process and test guidelines is available on the wiki page.

Tests are currently available in these formats:

HTML 5

HTML 5 tests sent as text/html

XHTML 1.1

XHTML 1.1 tests sent as application/xhtml+xml

XHTML 1.1 for Printers

XHTML 1.1 tests with all images converted from PNG to JPEG and formatted with headers and footers to ease testing of embedded printer software. This is not a canonical format, and some tests may fail due to the format conversion that would otherwise pass in the above XHTML 1.1 format.

Unless the test instructions explicitly indicate otherwise, any occurrence of red in a test indicates test failure.

Implementation Reports

An implementation report template is available to help with creating implementation reports. See also the explanation of its format.

Common Assumptions

Most of the test suite makes the following assumptions:

• The X/HTML div element is assigned display: block; and no other property declaration.
• The X/HTML span element is assigned display: inline; and no other property declaration.
• The X/HTML p element is assigned display: block;
• The X/HTML li element is assigned display: list-item;
• The X/HTML table elements table, tbody, tr, and td are assigned the display values table, table-row-group, table-row, and table-cell, respectively.
• The device can display the sixteen color values associated with the color keywords black, white, gray, silver, red, green, blue, purple, yellow, orange, teal, fuchsia, maroon, navy, aqua, and lime as distinct colors.
• The UA is set to print background colors and, if it supports graphics, background images.
• The UA implements reasonable page-breaking behavior; e.g., it is assumed that UAs will not break at every opportunity, but only near the end of a page unless a page break is forced.
• The UA implements reasonable line-breaking behavior; e.g., it is assumed that spaces between alphanumeric characters provide line breaking opportunities and that UAs will not break at every opportunity, but only near the end of a line unless a line break is forced.

Uncommon Assumptions

In addition, some of the tests make one or more of the following assumptions:

• The device is a full-color device.
• The device has a viewport width of at least 640px (approx).
• The resolution of the device is 96 CSS pixels per inch.
• The UA imposes no minimum font size.
• The 'medium' font-size computes to 16px.
• The initial value of 'color' is black.
• The canvas background is white.
• The user stylesheet is empty (except where indicated by the tests).
• The device is interactive and uses scroll bars.

The tests that need these assumptions to be true have not yet been marked, but it is likely that we will add a way to identify these tests in due course. Tests should avoid relying on these assumptions unless necessary.
