Azure Load Testing now supports uploading files greater than 50MB. For files other than JMeter scripts and user properties, if the file size exceeds 50MB, compress them into a ZIP file. Ensure that the ZIP file remains below 50 MB in size.
Azure Load Testing automatically unzips the file during the test run. Only five zip artifacts are allowed with a maximum of 1000 files in each zip and an uncompressed total size of 1 GB.
