Question

我有明确的申请。我设置了rspec和capybara。我写了简单的测试。

require 'rails_helper'

RSpec.feature "Log in", type: :feature do
  scenario 'as user' do
    User.create!(email: 'user@eample.com', password: 'password')
    visit '/users/sign_in'
    fill_in 'Email', with: 'user@example.com'
    fill_in 'Password', with: 'password'
    click_on 'Log in'
    expect(page).to have_content 'Signed in successfully.'
  end
end

此测试推送服务器记录到stdout（或stderr）。所以测试输入看起来像这样

> rspec
ActiveRecord::SchemaMigration Load (0.4ms)  SELECT "schema_migrations".* FROM "schema_migrations"
 (0.2ms)  BEGIN
 (0.2ms)  SAVEPOINT active_record_1
User Exists (1.7ms)  SELECT  1 AS one FROM "users" WHERE "users"."email" = 'user@example.com' LIMIT 1
SQL (0.4ms)  INSERT INTO "users" ("email", "encrypted_password", "created_at", "updated_at") VALUES ($1, $2, $3, $4) RETURNING "id"  [["email", "user@example.com"], ["encrypted_password", "$2a$04$6iqFDQXgBy/bC/1lYdzLV...1Da18lRiTyDaMJpWdi7EiK68Dcm6."], ["created_at", "2015-12-01 17:09:33.264145"], ["updated_at", "2015-12-01 17:09:33.264145"]]

...

Completed 200 OK in 19ms (Views: 18.1ms | ActiveRecord: 0.0ms)
   (0.4ms)  ROLLBACK
.

Finished in 0.49195 seconds (files took 0.45766 seconds to load)
1 example, 0 failures

的Gemfile：

group :development, :test do
  gem 'rspec-rails', '~> 3.0'
  gem 'capybara'
end

Gemfile.lock的：

...
rspec (3.4.0)
...
capybara (2.5.0)
...

spec_helper.rb和rails-helper.rb是默认值。

我尝试添加不使用capybara的示例：

require 'rails_helper'

describe Array do
  it { should respond_to :count }
end

但它返回类似的输出

> rspec spec/models/fake_test_spec.rb
  ActiveRecord::SchemaMigration Load (0.6ms)  SELECT "schema_migrations".* FROM "schema_migrations"
   (0.1ms)  BEGIN
   (0.1ms)  ROLLBACK
.

Finished in 0.00257 seconds (files took 0.36298 seconds to load)
1 example, 0 failures

有什么问题？我从未见过同样的行为。它只是开箱即用。我不会更改stderr或stdout变量...

哦不......我让读者感到困惑......我设置了我的应用程序以部署到heroku并使用gem 'rails_12factor'。它改变了记录器的行为。所以我把这个宝石移到production组，一切正常。

rspec将日志写入stdout而不是test.log
