pytest 8.4.1 (2025-06-17)

Bug fixes

• #13461: Corrected _pytest.terminal.TerminalReporter.isatty to support being called as a method. Before it was just a boolean which could break correct code when using -o log_cli=true).

• #13477: Reintroduced pytest.PytestReturnNotNoneWarning{.interpreted-text role="class"} which was removed by accident in pytest [8.4]{.title-ref}.

  This warning is raised when a test functions returns a value other than None, which is often a mistake made by beginners.

  See return-not-none{.interpreted-text role="ref"} for more information.
