#   We have generated the fixtures for the output of `sidecar-dump` utility.
#   We will use the fixtures to test the `sidecar-dump` utility.
#   However, the output is different when we are running it on different operation systems,
#   suck like Linux / Windows.
#   So we have to ignore the following characters:
#     - \r: --strip-trailing-cr
#     - spaces: --ignore-space-change
#     - blank-lines: --ignore-blank-lines
