### Test expected behavior of fx blobstats

# To update this test, you need to copy blob.manifest and blobs.json
# from your build configuration, and add all necessary packages to
# the data folder.
# Then, make sure to include these files to BT_FILE_DEPS and copy them
# to the temp folder in BT_SET_UP to make them available to the tests.
