[Proposal] Access to test result in on_exit

[Lars Vonk]

Hi,

I was looking for a way to access the test result of the failing test in the on_exit hook and found https://github.com/elixir-lang/elixir/issues/2969, but could not find any follow 

up.

What I am trying to achieve is to create a screenshot for each failing browser test (e.g. using Hound), this helps in trying to understand why a certain test failed. 

Basically this could look like:

setup context do

  on_exit(context, fn ->
    if context.test_failed
      take_screenshot("./tmp/#{context.test}.png")
    end
  end

  :ok
end

So this something you would consider, or is there already a way to implement this?

Thanks in advance,

Lars Vonk

Please open up an issue, we can definitely consider it. We may need to change some of the internals though if you want the failure reason in there.

Thanks for the quick reply. Created https://github.com/elixir-lang/elixir/issues/6938

I do not see a reason for adding the failure reason (yet). Typically the assertion failure says enough. The screenshot just helps in assessing what the screen looked like during the failure.
