Timecop: reset after each test

Timecop Show archive.org snapshot is a great gem to set the current time in tests. However, it is easy to introduce flakyness to your test suite when you forget to reset the time after the test.
This might be the case if:

• a test freezes time and a later test does not work for frozen time
• a later test needs the real current date to work correctly

Often you only notice these kinds of errors in rare cases when tests are executed in a particular order.

A way to avoid this is by using block notation (Timecop.travel(...) do) as this will automatically reset the time after the block.

My advice is to generally reset manipulated time after each test, so a developer can never forget to clean up.

reset after each spec

Reset after each spec by putting this to your spec_helper.rb:

Copyconfig.after(:each) do
  Timecop.return
end

reset after each feature

Put this to something like features/support/timecop.rb or features/step_definitions/time_steps.rb

CopyAfter do
  Timecop.return
end
