FTP Performance testing

The below  C# code was developed to place  EDI X12(HIPPA) files directly into the FTP folder for batch testing.

 

  The below script will also help

·         To  Test FTP server by placing larger number of files into FTP server as expected in production

·         To minimize the randomness in the testing process and ensures repeatability
