:eacces error when running mix_test_interactive on Windows

[Adhil-BIsquared]

Describe the bug
When running mix test.interactive on Windows, the process crashes with :eacces. It looks like the library tries to spawn a helper executable called zombie_killer that isn’t runnable on Windows.

Error output

09:37:59.946 [error] GenServer MixTestInteractive.InteractiveMode terminating
** (stop) :eacces
    erlang.erl:12788: :erlang.open_port({:spawn_executable, ~c"d:/Projects/todo_app/_build/dev/lib/mix_test_interactive/priv/zombie_killer"}, [:use_stdio, {:env, [{~c"MIX_ENV", ~c"test"}]}, :exit_status, :binary, :hide, {:args, ["mix", "test"]}])

Environment

• OS: Windows
• Elixir: 1.18.4
• Erlang/OTP 27
• mix_test_interactive: "~> 5.0"

Questions

• Is there Windows support for mix_test_interactive?
• We tried it on macOS and it worked, but why doesn’t it work on Windows?
• Is there any way to use it on Windows?

Hi @Adhil-BIsquared! mix test.interactive should work on Windows, though I don't have a way to test that.

It's only supposed to use the zombie killer script on non-Windows machines, so for some reason the Windows detection isn't working in your environment.

In an iex session, can you run :os.type() and report back what it shows?
