(Please prefix with `[ty]` for ty pull requests.) - Does this pull request include references to any relevant issues? --> ## Summary <!-- What's the purpose of the change? What does it do, and why? --> Closes #17347 Goal is to detect the useless exception statement not just for builtin exceptions but also custom (user defined) ones. ## Test Plan <!-- How was it tested? --> I added test cases in the rule fixture and updated the insta snapshot. Note that I first moved up a test case case which was at the bottom to the correct "violation category". I wasn't sure if I should create new test cases or just insert inside those tests. I know that ideally each test case should test only one thing, but here, duplicating twice 12 test cases seemed very verbose, and actually less maintainable in the future. The drawback is that the diff in the snapshot is hard to review, sorry. But you can see that the snapshot gives 38 diagnostics, which is what we expect. Alternatively, I also created this file for manual testing. ```py # tmp/test_error.py class MyException(Exception): ... class MyBaseException(BaseException): ... class MyValueError(ValueError): ... class MyExceptionCustom(Exception): ... class MyBaseExceptionCustom(BaseException): ... class MyValueErrorCustom(ValueError): ... class MyDeprecationWarning(DeprecationWarning): ... class MyDeprecationWarningCustom(MyDeprecationWarning): ... class MyExceptionGroup(ExceptionGroup): ... class MyExceptionGroupCustom(MyExceptionGroup): ... class MyBaseExceptionGroup(ExceptionGroup): ... class MyBaseExceptionGroupCustom(MyBaseExceptionGroup): ... def foo(): Exception("...") BaseException("...") ValueError("...") RuntimeError("...") DeprecationWarning("...") GeneratorExit("...") SystemExit("...") ExceptionGroup("eg", [ValueError(1), TypeError(2), OSError(3), OSError(4)]) BaseExceptionGroup("eg", [ValueError(1), TypeError(2), OSError(3), OSError(4)]) MyException("...") MyBaseException("...") MyValueError("...") MyExceptionCustom("...") MyBaseExceptionCustom("...") MyValueErrorCustom("...") MyDeprecationWarning("...") MyDeprecationWarningCustom("...") MyExceptionGroup("...") MyExceptionGroupCustom("...") MyBaseExceptionGroup("...") MyBaseExceptionGroupCustom("...") ``` and you can run this to check the PR: ```sh target/debug/ruff check tmp/test_error.py --select PLW0133 --unsafe-fixes --diff --no-cache --isolated --target-version py310 target/debug/ruff check tmp/test_error.py --select PLW0133 --unsafe-fixes --diff --no-cache --isolated --target-version py314 ``` |
