README
timecop.cr
Mock with Time.now with the power of time travel, time freeze and time scale.
Inspired by timecop ruby gem

Timecop.reset - [ ]
Timecop.travel - [ ]
Timecop.scale - [ ] Support nested block forms of scale, freeze and travel
Usage
require "timecop"
Time travel
NOTE: Not implemented yet
Timecop.travel(2.days.ago)
# Do some stuff 2 days ago
Timecop.travel(4.days.from_now)
# Do some stuff 2 days from now (2 days ago + 4 days from now = -2 + 4 = +2)
Block form:
# Normal time here
Timecop.travel(2.days.ago) do
# Do some stuff 2 days ago
end
# Again back to normal time
Time freeze
Timecop.freeze(2.days.ago)
# Do some stuff exactly 2 days ago
Block form:
Timecop.freeze(2.days.ago) do
# Time.now is always 2 days ago in this block
end
Difference between time travel and time freeze
Timecop.freeze is used to statically mock the concept of now. As your program executes, Time.now will always return the same value - value you provided as an argument to Timecop.freeze.
On the other hand Timecop.travel is dynamically mocks Time.now, ie: as your program executes, Time.now will change accordingly taking into account offset created by Timecop.travel.
Timecop.travel and Timecop.freeze both support nested calls. NOTE: Not implemented yet
Time scale
NOTE: Not implemented yet
Timecop.scale(1000)
# Now time goes 1000 times faster
Timecop.scale(0.001)
# Now time goes as normal
Timecop.scale(0.001)
# Now time goes 1000 times slower
Block form:
Timecop.scale(2.5) do
# here time goes 2.5 times faster
end
Resetting normal time flow
Timecop.reset
