team_city_ex_unit_formatting.ex does not handle ExUnit.Diff.container_to_algebra/5 output

[col]

Describe the bug
When a test fails the processes crashes and I don't get any test output in the console or in the test result pane.

To Reproduce
Steps to reproduce the behavior:

1. Upgraded to Elixir 1.10.2
2. Run a test that will fail
3. See error

Expected behavior
I expect to see the log output of the test and the test pane to lists all the tests that have passed and failed.

Screenshots
If applicable, add screenshots to help explain your problem.

I'm guessing since it is passing through ExUnit.Diff.container_to_algebra that I missed an update to the requirements for ExUnit.Formatters that they need to be able to transform the diff algebra and not assume the input is just an iolist.

[KronicDeth]

Looks like elixir-lang/elixir@98c6bba contains the changes to the cli_formatter that I need to port to support the pattern diffing added in Elixir 1.10.

[KronicDeth]

This test from elixir-lang/elixir@98c6bba can be used to reproduce the bug:

defmodule MyAppTest do
  use ExUnit.Case
 
  test "the truth" do
    assert ["Tvo", 1 | [:ok , {}]] = ["Two", :ok, self(), {true}]
  end
end

[KronicDeth]

Porting the changes worked

Awesome. Thank you @KronicDeth !

I faced it again after updating some parts.
My env is

• Intellij 2021.1.1 and
• elixir 1.9.4
• erlang 21.1
• elixir plugin: 11.10.0
• erlang plugin: 0.11.1108

My test is:

      assert 0 == 1

Thanks!
