Ruby/Rails获得了一些单元测试正则表达式问题。Ruby on Rails单元测试日期测试失败
运行:
- 的Rails 4.0.0
- 的Ruby 2.0.0-P247
- RVM 1.23.5
- 的Mac OSX 10.8.5
写一个applicaton_helper
方法这将根据日期有多远来格式化一个日期。这里的方法:
module ApplicationHelper
def humanize_datetime time
time = Time.at(time)
date = time.to_date
today = Date.today
time_format = "%-I:%M %p"
#if the time is within today, we simply use the time
if date == today
time.strftime time_format
# if the time is within the week, we show day of the week and the time
elsif today - date < 7
time.strftime "%a #{time_format}"
# if time falls before this week, we should the date (e.g. Oct 30)
else
time.strftime "%b %e"
end
end
end
这似乎是给了预期的效果,但由于某些原因,下面的测试失败:
require 'test_helper'
class ApplicationHelperTest < ActionView::TestCase
test "humanize_dateime should display only time when datetime is within today" do
formatted = humanize_datetime Time.now
assert_match /\A\d{1,2}\:\d\d (AM|PM)\z/, formatted
end
test "humanize_datetime should display day of week and time when datetime is not today but within week" do
yesterday_formatted = humanize_datetime (Date.today - 1).to_time # yesterday
assert_match /\A[a-zA-z]{3} \d{1,2}\:\d\d (AM|PM)\z/, yesterday_formatted
within_week_formatted = humanize_datetime (Date.today - 6).to_time # just within this week
assert_match /\A[a-zA-z]{3} \d{1,2}\:\d\d (AM|PM)\z/, within_week_formatted
end
test "humanize_datetime should display date when datetime is before this week" do
last_week_formatted = humanize_datetime (Date.today - 7).to_time
assert_match /\A[a-zA-Z]{3} \d{1,2}\z/, last_week_formatted
end
end
最后一次测试失败,给
1)失败: ApplicationHelperTest#test_humanize_datetime_should_display_date_when_datetime_is_before_this_week [/Users/mohammad/rails_projects/stopsmoking/test/helpers/application_helper_test.rb:20]: 预期/ \ [a-zA-Z] {3} \ d {1,2} \ z/to匹配“10月8日”。
考虑到正则表达式对我来说很合适,并且我已经在http://rubular.com/上测试了表达式,这真是非常棒。这里所有其他的测试都通过了。我也尝试在\d
之后删除字符串分隔符和量词的开始/结尾。
有关为什么会发生这种情况的任何想法?
我在3.2和4.0中测试了你的代码,它工作正常。你的正则表达式很好。别的东西坏了...... –
