  22. # DESCRIPTION:
    23. 

  23. # Test that injected decompression errors are handled correctly.

    25. 

  25. # STRATEGY:
    26. 

  26. # 1. Create an compressed dataset with a test file
    27. 

  27. # 2. Inject decompression errors on the file 20% of the time
    28. 

  28. # 3. Read the file to confirm that errors are handled correctly
    29. 

  29. # 4. Confirm that the decompression injection was added to the ZED logs
    30.
