Usage

Measuring Time

Given a test, that measures the duration of an operation, you can use the module Sus::Fixtures::Time::MeasuredContext to confirm the operation completes within a given time frame.

include Sus::Fixtures::Time::MeasuredContext

it 'should respond within the given timeout' do
	queue = Thread::Queue.new
	
	# Assume some operation that takes time:
	Thread.new do
		queue.push(:item)
	end
	
	expect{queue.pop}.to have_duration(be_measured_less_than(0.1))
end

Mocking Current Time

Given a test that depends on the current time, you can use the CurrentContext to control the current time.

include Sus::Fixtures::Time::CurrentContext

it 'should return the current time' do
	self.current_time = Time.at(0)
	
	expect(Time.now).to be == Time.at(0)
	
	time_travel(Time.at(1)) do
		expect(Time.now).to be == Time.at(1)
	end
end
