Running tests gets an error

[CoderDennis]

I get the following error when running mix test:

14:17:12.699 [notice] Protocol 'inet_tcp': register/listen error: econnrefused

** (MatchError) no match of right hand side value: {:error, {{:shutdown, {:failed_to_start_child, :net_kernel, {:EXIT, :nodistribution}}}, {:child, :undefined, :net_sup_dynamic, {:erl_distribution, :start_link, [%{clean_halt: false, name: :credo_language_server, name_domain: :shortnames, net_tickintensity: 4, net_ticktime: 60, supervisor: :net_sup_dynamic}]}, :permanent, false, 1000, :supervisor, [:erl_distribution]}}}
    test/test_helper.exs:2: (file)
    (elixir 1.14.4) lib/code.ex:1260: Code.require_file/2

It doesn't look like it has actually run any of the tests.

I'm running on an M2 MacBook Pro if that makes a difference.

i just merged some code last night that runs the user's code in an isolated node, and they connect through distributed erlang.

i am wondering if your epmd is not running

can you run epmd -daemon and then try again?

I ran epmd -daemon and now all 8 tests fail with the same runtime error (PIDs are different each time):

test code actions outer module (CredoLanguageServerTest)
     test/credo_language_server_test.exs:181
     ** (RuntimeError) failed to start child with the spec {CredoLanguageServer, [buffer: #PID<0.666.0>, cache: #PID<0.663.0>, task_supervisor: #PID<0.662.0>, runtime: #PID<0.664.0>]}.
     Reason: an exception was raised:
         ** (RuntimeError) Failed to boot runtime

[mhanberg]

now try and cd into test/support/project and run mix deps.get && mix compile

i'm still working through how this new isolated node is going to work, and am confused why output from the node is not being sent to the LSP

[CoderDennis]

After that, I get 7 out of 8 tests passing. The one that fails is test publishes diagnostics once the client has initialized (CredoLanguageServerTest) with Assertion failed, no matching message after 1000ms

Nevermind, that failure is because of a change I made locally. The main branch passes all tests. ;)

[mhanberg]

Nice, I'll close this issue but we'll get it figured out.
