Scenario Erasure of memory freed by killed userspace processes

Hooks

Before features/support/hooks.rb:269 0.002

Steps

Given I have started Tails from DVD without network and logged in 8.149

And I prepare Tails for memory erasure tests 0.460

When I start a process allocating 128 MiB of memory with a known pattern 4.596

Then patterns cover at least 128 MiB in the guest's memory 4.216

Output 1

Pattern coverage: 100.000% (128 MiB out of 128 MiB reference memory)

When I kill the allocating process 2.286

Then I find very few patterns in the guest's memory after 3 seconds 7.409

7.672%

7.672% of the free memory still has the pattern, but less than 0.800% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)

Output 1

Pattern coverage: 7.672% (68 MiB out of 889 MiB reference memory)
