MixAffected.Report (MixAffected v0.1.0)

Copy Markdown View Source

Compares a saved selection with the failures of the last full mix test.

ExUnit records failures in its failures manifest, the file mix test --failed reads: <Mix.Project.manifest_path()>/.mix_test_failures (or config :ex_unit, failures_manifest_path:), holding :erlang.term_to_binary({1, %{{module, test_name} => absolute_test_file}}), or {1, :all} when the run crashed (Elixir 1.18 and 1.19: see the private ExUnit.FailuresManifest module and Mix.Tasks.Test). Any other shape is reported as no failures plus a warning: this is shadow data and must never crash CI.
