+/// ## What it does
+/// Checks for `pytest.raises` calls without an expected exception.
+///
+/// ## Why is this bad?
+/// `pytest.raises` expects to receive an expected exception as its first
+/// argument. If omitted, the `pytest.raises` call will fail at runtime.
+///
+/// ## Example
+/// ```python
+/// import pytest
+///
+///
+/// def test_foo():
+///     with pytest.raises():
+///         do_something()
+/// ```
+///
+/// Use instead:
+/// ```python
+/// import pytest
+///
+///
+/// def test_foo():
+///     with pytest.raises(SomeException):
+///         do_something()
+/// ```
+///
+/// ## References
+/// - [API Reference: `pytest.raises`](https://docs.pytest.org/en/latest/reference/reference.html#pytest-raises)
