Bases: Mock

Mock version of

Only supports bucket, and the resulting object only supports the blob method. The resulting blob only supports the generate_signed_url method.

  • expected_expiration (Optional[timedelta], default: None) – The expiration that should be requested in a call to generate_signed_url on an underlying blob. A non-matching call will produce an assertion failure.

  • path (Optional[Path], default: None) – Root of the file path for blobs, if given. If not given, a simpler mock blob will be used that only supports generate_signed_url.

  • bucket_name (Optional[str], default: None) – If set, all requests for a bucket with a name other than the one provided will produce assertion failures.
