Also travis support for testing FF. See:
https://travis-ci.org/dart-lang/sdk/builds/159331789
On FF 48, 1965 out of 1979 tests are passing. Run locally:
DDC_BROWSERS=Firefox npm test
On Safari 10 (tech preview), it fails immediately due to a static method named "caller". We disallow it as a field, but not a method right now. If I hack that out, 1972 out of 1979 tests appear to pass.
Run locally by installing tech preview and running:
DDC_BROWSERS=Safari SAFARI_BIN=/Applications/Safari\ Technology\ Preview.app/Contents/MacOS/Safari\ Technology\ Preview npm test
