Mock with Time.now with the power of time travel, time freeze and time scale.

Inspired by timecop ruby gem

Add this to your application's shard.yml:

development_dependencies:
  timecop:
    github: waterlink/timecop.cr

• Timecop.freeze (normal and block forms)
• Timecop.reset

• Timecop.freeze
• Timecop.reset
• Timecop.travel
• Timecop.scale
• Support nested block forms of scale, freeze and travel

require "timecop"

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

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

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

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

Timecop.reset
