Trevor blogged Time Bomb Test in 2009, which made this article obsolete. Then, the day after, Jeremy McAnally wrote Deprecate, a gem to automate some versions of time bombing your tests.

Sometimes, I have an idea for a test, but I am testing something else and I don’t want to break my thought flow.

In those cases, I will write myself a time bomb:

1 def test_has_more_entries_after_update
2   flunk if > Time.local(2005, 12, 9, 10, 0, 0)
3 end

This test will pass, until Dec 9 2005, 10 AM. Nice way to not forget to add some tests.
