tests.large_resource

This MC generates a new binary file, gets its hash, and then drop both the binary and the hash_compare.py VMR on every VM in the experiment. The size of the generated binary can be passed in (using bytes), but the default is 1048576 (i.e. 1 MB). This MC is mainly useful for functional testing of FIREWHEEL.

Bases: AbstractPlugin

Add a newly generated VM resource containing random bytes to each VM in the experiment.

run(size='1048576', location_dir='/tmp', preload='True')[source]

Generate a new binary file, get its hash, and then drop both the binary and the hash_compare.py VMR on every VM in the experiment.

Parameters:

size (str, optional) – The size in bytes. The default is 1048576 (i.e. 1 MB).
location_dir (str, optional) – Where to place the file on the VM. Default is "/tmp".
preload (str, optional) – Whether of not to push the file into the VM before negative time starts. Should be either "True" or "False". Defaults to "True".
