Project

Here is the list of the things I've been working on. I hope this will help someone who will be working on this stuff later on.

Bugs @ bugzilla

This is a list of bugs which I was working on.

Main bug

• implement user font set object
  • https://bugzilla.mozilla.org/show_bug.cgi?id=441473

Test case

• Implement tests for @font-face rules
  • https://bugzilla.mozilla.org/show_bug.cgi?id=452870

In the tree, tests are checked in the following location: src/layout/reftest/fonts/downloadable-font-xyz.html

Fonts we use

These bugs are filed so that testers and legal team? people can easily update and share information. We need this since we have to check if these fonts can be checked in into the build tree, in terms of license.

• [Font] Sazanami Font for downloadable font testing
  • https://bugzilla.mozilla.org/show_bug.cgi?id=453917
• [Font] Sazanami Font for downloadable font testing
  • https://bugzilla.mozilla.org/show_bug.cgi?id=453919
• We would like to use the cmb10.otf font (among others possibly) for testing
  • https://bugzilla.mozilla.org/show_bug.cgi?id=454314

Followup bugs

Since I wrote this document quite a while ago, I'm afraid these bugs might be already fixed and resolved. Please make sure to check it in advance.

Wiki Documents

These are the documentations I wrote about @font-face rule tests.

@font-face Test Plan

https://wiki.mozilla.org/QA/Firefox3.1/FontFace_TestPlan

This page show the plan of tests I've came up with. Almost all of them were actually done, but some of them are not checked in. Especially, most of the pair-wise tests were conducted just to check whether a bug exists or not.

@font-face Test Status

https://wiki.mozilla.org/QA/Firefox3.1/FontFace_TestStatus

This page shows the current status of @font-face test. I listed up the tests I've done, suspected features and bugs I've found, and all other status here. This page should have the latest information about how the @font-face test is going.

Other references

Specifications, helpful websites, etc

• Specification - W3C CSS Fonts Level 3
  • http://dev.w3.org/csswg/css3-fonts/

This web site helped me a lot. All the rules and how to use them are written here. But you also have to make sure you follow the conversations on bugzilla comments, since they sometimes find out that specification has some faults and they would come up with better solutions. That will make the implementation different from the document above, so you have to be careful not to miss those changes.

Little more information about myself

Currently, I'm a first-year student of Graduate School of Science Technology, Keio University, Japan. My major is computer science, and I'm studying about software testing.
