调研方向

Read step 2.7 of the code-quality plan and inspect rules/registry.toml for how ratcheted rules are registered. Then review existing rule implementations, tests under scripts/rules/tests/, and the 22 baseline cases described in the issue. Done means the rule detects the listed assertion forms and helper calls, records current exceptions in a baseline under rules/baselines/, and the baseline can only shrink; pull request #4188 is already open.

描述

What

Add a quality guard that fails on any test function that checks nothing: one that contains no assert, no pytest.raises (or pytest.warns, pytest.fail), no unittest self.assert... or self.fail, no mock assert_called... or other call to an assert... function, no raise AssertionError, and no call to a helper that does one of these. Today's tests that check nothing go in a baseline file under rules/baselines/, which can only shrink.

Why

A test without a check passes whatever the code returns, as long as nothing raises. Of the 3,013 test functions in tests/ and scripts/rules/tests/, 22 check nothing today, for example tests/unit/test_warmup.py::test_run_startup_warmup_swallows_calculate_errors. Most of these only show that a call doesn't raise. They pass even if the call returns the wrong value.

This is the "every test function asserts something" check in step 2.7 of the code-quality plan, registered in rules/registry.toml as a ratcheted rule.
