Scenario Erasure of memory freed by killed userspace processes

Hooks

Before features/support/hooks.rb:269 0.003

Steps

Given I have started Tails from DVD without network and logged in 8.301

And I prepare Tails for memory erasure tests 0.432

When I start a process allocating 128 MiB of memory with a known pattern 2.443

Then patterns cover at least 128 MiB in the guest's memory 3.589

Output 1

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

When I kill the allocating process 1.792

Then I find very few patterns in the guest's memory 4.305

4.906%

4.906% of the free memory still has the pattern, but less than 0.800% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
./features/step_definitions/erase_memory.rb:219:in `/^I find very few patterns in the guest's memory$/'
features/erase_memory.feature:19:in `Then I find very few patterns in the guest's memory'

Output 1

Pattern coverage: 4.906% (44 MiB out of 898 MiB reference memory)
