I just was going through the test-suite, in three browsers, submitting results automatically and manually. Then I noticed ~"This test requires the Ahem font to be installed" - thus probably many test results were false.

Would it be possible to @font-face the Ahem font? (Everywhere, or for each test that requires it).

Then testing won't go wrong as it just did.
