Subject: fix(tests): use bodyBuffer for binary gzip data in MockServerResponse
X-Git-Tag: ocpp-server@v2.3.0~3
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=6abbf542c66ffe2f9461e5a66c18476d8b2b8389;p=e-mobility-charging-stations-simulator.git

fix(tests): use bodyBuffer for binary gzip data in MockServerResponse

Buffer.from(string, 'binary') loses data on Windows due to encoding
differences. Store raw Buffer directly for binary content like gzip.
