You need to start your tests inside an iex session - you can do that by running iex -S mix test. Then you can use IEx.pry inside your test:
require IEx test "the truth" do one = 1 IEx.pry assert one + one == 2 end
You'll be asked if you want to allow prying into the session:
Request to pry #PID<0.143.0> at test/test_app_test.exs:7. Allow? [Yn]
And all the context at that point will be available to you:
pry(1)> one
1

I'm pretty new in Elixir, but have a lot fun with it!
I came from Ruby world, so start looking analogy. And there is exist debugging tool
pry. Usingbinding.pryI can interrupt any session. I found something similar in Elixir –IEx.pry. But it doesn't work when I'm testing something throughExUnit.Question – is it is possible to interrupt testing session and run iex with current environment?
