Thanks for the report @ordian!

I don't have any macOS machine present so pretty hard for me to investigate this unfortunately... We would happily accept a pull request that resolves this and makes it work on macOS.

hi @ordian ! are you still running into this issue?

[ordian]

hey @ashleygwilliams! it seems like an incompatible chromedriver is installed by default on macOS
See paritytech/parity-common#226 (comment)
We're using this workaround for now.

I'm not sure if it's a bug in https://github.com/rustwasm/wasm-pack/blob/15e354f19ccef26cb7baca5dacda1bcd2f9904a2/src/test/webdriver/chromedriver.rs though.
