Ruby on rails 带变量的RSpec存根对象方法
在测试助手时,我遇到了一个问题 我在模型上有一个作用域:Ruby on rails 带变量的RSpec存根对象方法,ruby-on-rails,rspec-rails,Ruby On Rails,Rspec Rails,在测试助手时,我遇到了一个问题 我在模型上有一个作用域: 任务。到期日(天) 这在助手中引用: module UsersHelper ... def show_alert(tasks, properties, user) pulse_alert(tasks, properties) || tasks.due_within(7).count.positive? || tasks.needs_more_info.count.positive? ||
任务。到期日(天)
这在助手中引用:
module UsersHelper
...
def show_alert(tasks, properties, user)
pulse_alert(tasks, properties) ||
tasks.due_within(7).count.positive? ||
tasks.needs_more_info.count.positive? ||
tasks.due_within(14).count.positive? ||
tasks.created_since(user.last_sign_in_at).count.positive?
end
...
end
因此,我正在测试任务
、属性
和用户
的存根:
RSpec.describe UsersHelper, type: :helper do
describe '#show_alert' do
it 'returns true if there are tasks due within 7 days' do
tasks = double(:task, due_within: [1, 2, 3, 4], past_due: [])
properties = double(:property, over_budget: [], nearing_budget: [])
user = double(:user)
expect(helper.show_alert(tasks, properties, user)).to eq true
end
it 'returns true if there are tasks due within 14 days' do
# uh oh. This test would be exactly the same as above.
end
end
end
这是通过的,但是当我为编写测试时,如果在14天内有任务到期,它将返回true
,我意识到我的double(:task,due_inthe:[])
不会与提供给方法的变量交互
如何编写关心提供给方法的变量的存根?
显然,这是行不通的:
tasks = double(:task, due_within(7): [1, 2], due_within(14): [1, 2, 3, 4])
为了处理不同的案件,你能试试这样的吗
allow(:tasks).to receive(:due_within).with(7).and_return(*insert expectation*)
allow(:tasks).to receive(:due_within).with(14).and_return(*insert expectation*)
由于您正在测试show_alert方法,您可能希望将您的测试单独隔离到show_alert方法,即如上所述的mock due_in的返回值。due_的功能将在单独的测试用例中处理。@Jessler FTW!谢谢是的,
Task.due_in(days)
是一个模型范围,在spec/models/Task\u spec.rb
中进行了测试,这就是为什么我要保留响应。
