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 13.400

And I prepare Tails for memory erasure tests 0.428

When I start a process allocating 128 MiB of memory with a known pattern 2.306

Then patterns cover at least 128 MiB in the guest's memory 3.408

Output 1

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

When I kill the allocating process 0.419

Then I find very few patterns in the guest's memory after 3 seconds 6.072

9.437%

9.437% 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: 9.437% (82 MiB out of 873 MiB reference memory)
