22# DESCRIPTION:
23# Test that injected decompression errors are handled correctly.
24#
25# STRATEGY:
26# 1. Create an compressed dataset with a test file
27# 2. Inject decompression errors on the file 20% of the time
28# 3. Read the file to confirm that errors are handled correctly
29# 4. Confirm that the decompression injection was added to the ZED logs
