Issue when running on Windows

[CallumVass]

Hi,

I wasn't sure to create a new issue or discussion so I've gone with discussion for now.

I'm trying to set up Wallaby as described in this page, which is using 0.28 of Wallaby: https://www.tddphoenix.com/setting-up/

I've followed all the instructions and triple checked to make sure my code is correct, however, when I run the first smoke test - I get the following error:

[error] GenServer Wallaby.Chrome.Chromedriver terminating
** (stop) :eacces
    erlang.erl:2217: :erlang.open_port({:spawn_executable, 'c:/Development/elixir/chatter/_build/test/lib/wallaby/priv/run_command.sh'}, [:binary, :stream, :use_stdio, :stderr_to_stdout, :exit_status, {:args, ["chromedriver", "--log-level=OFF", "--port=59814"]}])
    (wallaby 0.28.0) lib/wallaby/chrome/chromedriver/server.ex:96: Wallaby.Chrome.Chromedriver.Server.handle_continue/2

    (stdlib 3.12) proc_lib.erl:249: :proc_lib.init_p_do_apply/3
Last message: {:continue, :start_chromedriver}

I have configured the chromedriver to be on my PATH variable, for example I can run chromedriver from command line to see its running successfully. It's also the same version as what my Chrome is.

Here is the result of running elixir -v:

elixir -v
Erlang/OTP 22 [erts-10.7] [64-bit] [smp:16:16] [ds:16:16:10] [async-threads:1]

Elixir 1.11.2 (compiled with Erlang/OTP 21)

Has anyone else found issues when running it on Windows? Thanks

Thanks for asking your question as a discussion @CallumVass!

It looks like you're getting an :acces error when erlang attempts to start the chromedriver process.

This leads me to think it's a permissions issue on the chromerdriver executable, so that would be where I suggest looking first.

Oh that would be great - I'm surprised no one has seen this issue before unless no one is developing on Windows it seems?

I found this guy was having the same issue as me: https://elixirforum.com/t/test-driven-development-with-phoenix-self-published-free/35154/13

I've configured sh to be in my PATH as I have Git for Windows installed, this now works from within iex:

System.cmd("sh", ["c:/Development/elixir/chatter/_build/test/lib/wallaby/priv/run_command.sh", "chromedriver"], into: IO.stream(:stdio, :line))

Hmm, interesting. I'm pretty sure that the script uses bash so I'm surprised to see it works using sh

[CallumVass]

I think the best solution could be to have a .bat file and then call that if the OS is windows rather than the .sh file.
