//! Regression coverage for the Go test-file import set.
//!
//! Split out of `tests.rs`, which is over the 1000-line cap and may not grow. The import list was
//! derived from a heuristic that never consulted `fixture.env.api_key_var`, so a fixture declaring
//! only an API-key variable emitted `os.Getenv` with no `os` import. ~keep

/// Regression test: a fixture that declares `env.api_key_var` but has no
/// `mock_response`/`http` and no `client_factory` override emits `os.Getenv` in
/// its live-API-key skip branch (see `test_function.rs`'s `api_key_var` handling).
/// The old `needs_os` heuristic in `test_file.rs` only recognized http tests,
/// `client_factory` overrides, `mock_url`/`mock_url_list` args, and bytes-as-path
/// args -- it never checked `fixture.env.api_key_var`, so this exact shape
/// referenced `os.` in the rendered body without importing `"os"`.
