There was a problem hiding this comment.
Look good to me! I have a nit related to how we ignore the 0 collected tests. Not blocking as it shouldn't cause any issues immediately

WinRM deferrable mode breaks with non-UTF8 output encodings
8fc49f4
providers/microsoft/winrm/src/airflow/providers/microsoft/winrm/triggers/winrm.py | providers/microsoft/winrm/src/airflow/providers/microsoft/winrm/operators/winrm.py
The new deferrable WinRM trigger base64-encodes stdout/stderr and immediately decodes those bytes using the user-supplied output_encoding. Base64 data is ASCII; decoding it with encodings like UTF-16 produces non-ASCII characters. When the operator resumes, _decode() calls base64.standard_b64decode on those strings, which raises because the string is not ASCII. This means deferrable mode will crash for non-ASCII output encodings (e.g., UTF-16LE output from Windows), a regression introduced by this commit.
