/*

|
*
|
|
* This file is #included directly by gfxFontSelectionTest.cpp, and as
|
|
* such does not need any #include files or similar. (However, should
|
|
* any extra ones be required, it should be ok to do so, as well as
|
|
* defining new functions, etc.
|
|
*
|
|
* To add a new test, call AddTest with the following arguments: the
|
|
* CSS font-family string, the gfxFontStyle, an enum (either S_ASCII
|
|
* or S_UTF8) indicating the string type, and then the text string
|
|
* itself as a string literal. Unfortunately there is no good way to
|
|
* embed UTF8 directly into C code, so hex literals will need to be
|
|
* placed in the string. Because of the way \x is parsed things like
|
|
* "\xabcd" won't work -- you have to do "\xab""cd". "\xab\x01\x03"
|
|
* will work fine, though.
|
|
*
|
|
* The result of AddTest should be assigned to the variable t; after
|
|
* AddTest, one or more calls to t->Expect() should be added to define
|
|
* the expected result. Multiple Expect() calls in a row for the same
|
|
* platform mean that the resulting glyph/font selection items needs
|
|
* to have as many items as there are Expect() calls. (See below for
|
|
* examples.)
|
|
*
|
|
* The arguments to Expect are:
|
|
*
|
|
* platform - a string identifying the platform.
|
|
* Valid strings are "win32", "macosx", and "gtk2-pango".
|
|
* font - a string (UTF8) giving the unique name of the font.
|
|
* See below for how the unique name is constructed.
|
|
* glyphs - a set of glyph IDs that are expected.
|
|
* This array is constructed using a GLYPHS() macro.
|
|
*
|
|
* GLYPHS() is just a #define for LiteralArray, which is defined
|
|
* in gfxFontSelectionTest.cpp -- if you need more array elements
|
|
* than available, just extend LiteralArray with a new constructor
|
|
* with the required number of unsigned longs.
|
|
*
|
|
* The unique font name is a platform-specific constructed string for
|
|
* (mostly) identifying a font. On Mac, it's created by taking the
|
|
* Postscript name of the font. On Windows, it's created by taking
|
|
* the family name, and then appending attributes such as ":Bold",
|
|
* ":Italic", etc.
|
|
*
|
|
* The easiest way to create a test is to add a call to AddTest, and
|
|
* then run the test. The output will include a list like:
|
|
*
|
|
* ==== Test 1
|
|
* expected:
|
|
* Run[ 0]: 'Verdana' 73 82 82
|
|
* Run[ 1]: 'MS UI Gothic' 19401
|
|
* Run[ 2]: 'Verdana' 69 68 85
|
|
* Test 1 failed
|
|
*
|
|
* This gives you the information needed for the calls to Expect() --
|
|
* the unique name, and the glyphs. Appropriate calls to expect for
|
|
* the above would be:
|
|
*
|
|
* t->Expect ("win32", "Verdana", GLYPHS(73, 82, 82));
|
|
* t->Expect ("win32", "MS UI Gothic", GLYPHS(19401));
|
|
* t->Expect ("win32", "Verdana", GLYPHS(69, 68, 85));
|
