我正在编写一个单元测试来检查 24 小时是否已经过去。如果 24 小时过去了，那么它应该返回 true

这是我的尝试

test   "messenger tag is more than 24 hours" do
        
        Timecop.travel 2.days.ago
        account = accounts(:messenger_v2)
        contact_d = Contact.create! account: account, name: 'Mr Right', phone_number: nil, external_id: '155581474881005', contact_type: 'MessengerV2', source: 'Inbound', is_registered: true, primary_contact: true
        conversation = Conversation.create! contact: contact_d, account: account, status: 'Open', unread: true, conversation_type: 'Private'
        Message.create! contact: contact_d, message_type: 'Text', text: 'I have some enquries', direction: 'IN', account: account, conversation: conversation, external_id: "in_a#{Time.now.to_i.to_s}"
        msg = conversation.messages.incoming
        time_created = msg.last.created_at
        messenger_tags = time_created < 24.hours.ago
        assert_equal true, messenger_tags
            
    end

当我在这里运行测试时是输出

test_messenger_tag_is_more_than_24_hours                        FAIL (0.14s)
        Expected: true
          Actual: false
        test/models/message_test.rb:175:in `block in <class:MessageTest>'

请协助

您需要在创建消息后turn off Timecop使用Timecop.return。

test "messenger tag is more than 24 hours" do
    Timecop.travel 2.days.ago
    account = accounts(:messenger_v2)
    contact_d = Contact.create! account: account, name: 'Mr Right', phone_number: nil, external_id: '155581474881005', contact_type: 'MessengerV2', source: 'Inbound', is_registered: true, primary_contact: true
    conversation = Conversation.create! contact: contact_d, account: account, status: 'Open', unread: true, conversation_type: 'Private'
    Message.create! contact: contact_d, message_type: 'Text', text: 'I have some enquries', direction: 'IN', account: account, conversation: conversation, external_id: "in_a#{Time.now.to_i.to_s}"
    Timecop.return
    msg = conversation.messages.incoming
    time_created = msg.last.created_at
    messenger_tags = time_created < 24.hours.ago
    assert_equal true, messenger_tags
end

更新 或者你可以阻止Timecop.travel，以避免Timecop.return@Stefan在下面的评论中提到的调用

test "messenger tag is more than 24 hours" do
    Timecop.travel 2.days.ago do
        account = accounts(:messenger_v2)
        contact_d = Contact.create! account: account, name: 'Mr Right', phone_number: nil, external_id: '155581474881005', contact_type: 'MessengerV2', source: 'Inbound', is_registered: true, primary_contact: true
        conversation = Conversation.create! contact: contact_d, account: account, status: 'Open', unread: true, conversation_type: 'Private'
        Message.create! contact: contact_d, message_type: 'Text', text: 'I have some enquries', direction: 'IN', account: account, conversation: conversation, external_id: "in_a#{Time.now.to_i.to_s}"
        msg = conversation.messages.incoming
        @time_created = msg.last.created_at
    end
    messenger_tags = @time_created < 24.hours.ago
    assert_equal true, messenger_tags
end
