当我检查我的fixtures users.yml文件时,我看到我正在使用时区ruby戳：

michael:
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>
  admin: true
  activated: true
  activated_at: <%= Time.zone.now %>

archer:
  name: Sterling Archer
  email: duchess@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

lana:
  name: Lana Kane
  email: hands@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

mallory:
  name: Mallory Archer
  email: boss@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

<% 30.times do |n| %>
user_<%= n %>:
  name:  <%= "User #{n}" %>
  email: <%= "user-#{n}@example.com" %>
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>
<% end %>

我的db / seeds.rb文件如下所示：

User.create!(name:  "Example User",email: "example@railstutorial.org",password:              "foobar",password_confirmation: "foobar",admin: true,activated: true,activated_at: Time.zone.now)

99.times do |n|
  name  = Faker::Name.name
  email = "example-#{n+1}@railstutorial.org"
  password = "password"
  User.create!(name:  name,email: email,password:              password,password_confirmation: password,activated_at: Time.zone.now)
end

编辑：这是测试

测试/邮寄者/ user_mailer_test.rb：

require 'test_helper'

class UserMailerTest < ActionMailer::TestCase

  test "account_activation" do
    mail = UserMailer.account_activation
    assert_equal "Account activation",mail.subject
    assert_equal ["to@example.org"],mail.to
    assert_equal ["from@example.com"],mail.from
    assert_match "Hi",mail.body.encoded
  end

  test "password_reset" do
    mail = UserMailer.password_reset
    assert_equal "Password reset",mail.body.encoded
  end
end

有什么我做错了吗？谢谢您的帮助.
