The first range test case fail for a strange reason : `GET Individual VNF Package Artifact with Range Request and NFVO supporting Range Requests` `bytes 0-1023/22872 != bytes=0-1023/22872` But after that point range is used in : `Individual VNF Package Artifact with Range Request and NFVO not supporting Range Requests` Then bad range is set, and used for all other test cases.
