RSpec Stub 不覆盖多个嵌套的描述块
我有一个结构如下的测试套件：
describe ... do
[list of dates].each do
describe
before(:all) do
base_date = ...
end
describe ... do
[list of times].each do
describe ... do
before(:all) do
base_time = base_date + ...
DateTime.stub!(:now).and_return(base_time)
end
describe ... do
<test using records within date-time range based on base_time>
end
describe ... do
<another test using records within date-time range based on base_time>
end
end
end
end
end
end
end
第一个测试具有 DateTime(now) == base_time，但第二个测试为 DateTime(now) == 我计算机的日期时间，表明存根不再有效。将 stub! 调用移动到每个 describe 循环中可以解决该问题，但我想了解为什么它不能按编写的方式工作。
I have a test suite structured as follows:
describe ... do
[list of dates].each do
describe
before(:all) do
base_date = ...
end
describe ... do
[list of times].each do
describe ... do
before(:all) do
base_time = base_date + ...
DateTime.stub!(:now).and_return(base_time)
end
describe ... do
<test using records within date-time range based on base_time>
end
describe ... do
<another test using records within date-time range based on base_time>
end
end
end
end
end
end
end
The first test has DateTime(now) == base_time, but the second test as DateTime(now) == my computer's date-time, indicating that the stub is no longer in effect. Moving the stub! call into each describe loop resolves the problem, but I would like to understand why it doesn't work as written.

原因可能在于其他地方，存根与多个嵌套描述块一起工作得很好。也许 :all 与 :each 是问题所在：
before(:all)在所有描述块执行之前执行一次，而before(:each)每次执行之前执行描述块。或者可能与存根 DateTime 有关，您尝试过吗
The reason lies probably elsewhere, stubs work fine with multiple nested describe blocks. Maybe :all vs :each is the problem:
before(:all)is executed once before all describe blocks are executed, whilebefore(:each)is executed each time before a describe block is executed.Or maybe it has something to do with stubbing DateTime, have you tried
