I have the following examples:
describe "#subscription_cancelled_at" do
let!(:user) { FactoryBot.create(:user, stripe_id: 'stripe') }
let!(:stripe_customer) { Stripe::Customer.new }
let!(:past_date) { 2.weeks.ago }
let!(:future_date) { 2.weeks.from_now }
let!(:subscription) { build_deep_struct(status: 'active',
cancel_at_period_end: false, canceled_at: nil, current_period_end: future_date)
}
it 'returns nil if there is no subscription' do
allow(user).to receive(:stripe_customer).and_return(nil)
expect(user).to receive(:stripe_customer)
expect(stripe_customer).to_not receive(:subscriptions)
expect(user.subscription_cancelled_at).to be_nil
end
it "returns canceled_at if it is populated" do
subscription.canceled_at = past_date
allow(user).to receive(:stripe_customer).and_return(stripe_customer)
allow(stripe_customer).to
receive(:subscriptions).and_return([subscription])
expect(user).to receive(:stripe_customer)
expect(stripe_customer).to receive(:subscriptions)
expect(user.subscription_cancelled_at.utc).to eq past_date
end
it "returns current_period_end if subscription will cancel at period end" do
subscription.cancel_at_period_end = true
allow(user).to receive(:stripe_customer).and_return(stripe_customer)
allow(stripe_customer).to
receive(:subscriptions).and_return([subscription])
expect(user).to receive(:stripe_customer)
expect(stripe_customer).to receive(:subscriptions)
expect(user.subscription_cancelled_at).to eq future_date
end
it 'returns false otherwise' do
allow(user).to receive(:stripe_customer).and_return(stripe_customer)
allow(stripe_customer).to
receive(:subscriptions).and_return([subscription])
expect(user).to receive(:stripe_customer)
expect(stripe_customer).to receive(:subscriptions)
expect(user.subscription_cancelled_at).to be_nil
end
end
All that’s really going on here is that I’m passing the dates through some data
structures and eventually returning the expected dates. There is no date math
(or conversion) involved behind the scenes. However, I get these results:
1) User::StripeCustomer#subscription_cancelled_at returns canceled_at if it
is populated
Failure/Error: expect(user.subscription_cancelled_at.utc).to eq @@past_date

Notice that the times being compared are off by very small amounts (< 1 sec). I
tried replacing the “let!” commands with assignments to class variables
(@@past_date, etc) in an attempt to ensure that the let! blocks were not being
re-evaluated each time they were referenced, but that was not the case.
I can certainly change the test to check for a time “close” to the expected
time, but that is a hack. Can anyone explain why I’m getting these differences?
