I found recently that W3C published very good written tests for SVG. Today I spent my lunch time to run across these tests in different browsers. Here results:
| Browser | Passed |
|---|---|
| Total number of tests | 276 |
| Opera 9.51 | 246 |
| Safari 4 | 218 |
| Firefox 3.0.1 | 160 |
| Internet Explorer | 0 |
Basically Opera is the best so far. Safari doesn’t support filters. Firefox has problems with fonts and doesn’t support animation.
