Root Cause

pytest-freezegun/freezegun-time plugin exposes `frozen_time` as a low-level helper; tests must request `freezer` (the fixture) which manages freeze/thaw lifecycle.

generic

中文

pytest-freezegun/freezegun-time 插件将 `frozen_time` 作为底层辅助对象暴露；测试必须请求 `freezer`（fixture），由它管理冻结/解冻生命周期。

Workarounds

  1. 95% success 
    Request the freezer fixture:

def test_expiry(freezer):
    freezer.move_to('2024-01-01')
    assert is_expired()
  2. 92% success 
    Or use the decorator form:

from freezegun import freeze_time

@freeze_time('2024-01-01')
def test_expiry(): ...

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The plugin detects direct access and raises the same failure.

  2. 80% fail

    Bypasses the fixture and leaves time frozen across other tests, causing cascading failures.
