How about `assert_no_warnings`? Not sure if `supress_warnings` is a bit over the top?

```python
from contextlib import contextmanager
import warnings

@contextmanager
def assert_no_warnings():

    with warnings.catch_warnings(record=True) as record:
        yield
        assert len(record) == 0, ""got unexpected warning(s)""

@contextmanager
def supress_warnings(*messages):

    messages = ("""",) if not messages else messages
    with warnings.catch_warnings():
        for message in messages:
            warnings.filterwarnings(""ignore"", message)
        yield
```


```python
with supress_warnings():
    warnings.warn(""test"")

with supress_warnings(""test""):
    warnings.warn(""test"")

with supress_warnings(""not test"", ""something else""):
    warnings.warn(""test"")

with assert_no_warnings():
    pass

with assert_no_warnings():
    warnings.warn(""test"")
```
