Tests for WBE Chapter 3 Exercise Small Caps

Make the <abbr> element render text in small caps~~, like this~~. Inside an <abbr> tag, lower-case letters should be small, capitalized, and bold, while all other characters (upper case, numbers, etc) should be drawn in the normal font.

Tests

Testing boilerplate:

>>> import wbemocks
>>> _ = wbemocks.socket.patch().start()
>>> _ = wbemocks.ssl.patch().start()
>>> _ = wbemocks.patch_canvas()
>>> import browser
>>> browser.set_parameters(WIDTH=800)
>>> def test_layout(text):
...   dl = browser.Layout(browser.lex(text)).display_list
...   return wbemocks.normalize_display_list(dl)

For lowercase input use a bold font half the normal size, and convert all characters to uppercase.

>>> test_layout("<abbr>half</abbr>") #doctest: +NORMALIZE_WHITESPACE
[(13.0, 19.5, 'HALF', Font size=8 weight=bold slant=roman style=None)]

All characters that are not lowercase should use the normal font, and the spacing between words should use the normal font as well.

>>> test_layout("<abbr>1234 ABCD</abbr>") #doctest: +NORMALIZE_WHITESPACE
[(13.0, 21.0, '1234', Font size=16 weight=normal slant=roman style=None),
 (93.0, 21.0, 'ABCD', Font size=16 weight=normal slant=roman style=None)]

Combining the two we get small caps. Runs of characters in a word that use the same font are presented using single display_list entries.

>>> test_layout("<abbr>Small Caps</abbr>") #doctest: +NORMALIZE_WHITESPACE
[(13.0, 21.0, 'S', Font size=16 weight=normal slant=roman style=None), 
 (29.0, 27.0, 'MALL', Font size=8 weight=bold slant=roman style=None), 
 (77.0, 21.0, 'C', Font size=16 weight=normal slant=roman style=None), 
 (93.0, 27.0, 'APS', Font size=8 weight=bold slant=roman style=None)]

Other text should not interfere with the small caps text.

>>> test_layout("It's like YELLING <abbr>Quietly</abbr>") #doctest: +NORMALIZE_WHITESPACE
[(13.0, 21.0, "It's", Font size=16 weight=normal slant=roman style=None),
