仅为一个规范文件定义的顺序答案

【问题标题】：Defined order just for one spec file仅为一个规范文件定义的顺序
【发布时间】：2014-01-03 05:53:57
【问题描述】：

我更喜欢以随机顺序运行我的 RSpec (2.14) 规范，所以我添加了

config.order = 'random'

致我的 spec_helper

但是，对于一个且只有一个文件，我需要按照它们的写入顺序运行它们。

我修改了我的文件如下

describe ApiAuthentication do 
  RSpec.configure do |config|
    config.order = 'defined'
  end

  it'....'
  end
end

但它们仍然以随机顺序执行。

有没有办法为 1 个文件指定定义的顺序？

谢谢

This blog post 建议是。看Configuration#order_groups_and_examples方法。

【解决方案2】：

我刚刚在 Rspec 2 中完成了这项工作 - 就我而言，我在一个规范文件中混合了有序和无序测试，因此我使用了以下内容：

# order by a number at start of the description (default 0) and then random
# note 'describe' groups always sort after 'it' examples
RSpec.configure do |config|
  config.order_groups_and_examples do |list|
    list.sort_by { |item| [item.description.sub(/^(\d*).*/, '\1').to_i, rand] }
  end
end

结合使用 describe 进行分组，这解决了我的要求（大多数测试我不关心顺序，但有一些我想要按顺序或在最后）。例如：

it "1: starts when asked to"
it "1: should do something"
it "waves happily"
it "snores loudly"
describe "9: at the end" do
  it "stops when asked to"
end

describe "4: some grouping" do
  it "does another thing"
  it "has weight"
end

describe "4: another group" do
  it "waddles like a duck"
  it "quacks like a duck"
end

按以下顺序运行：

# next two in random order
it "waves happily"
it "snores loudly"

# next two in random order
it "1: should do something"
it "1: starts when asked to"

# next two describe blocks in random order, and their examples within then in random order
describe "2: another group" do
  it "waddles like a duck"
  it "quacks like a duck"
end
describe "2: some grouping" do
  it "does another thing"
  it "has weight"
end

# NOTE: an it "9: something" example without a surrounding
#  describe block would run before all the describe blocks.

# this will run at the end
describe "9: at the end" do
  it "stops when asked to"
end
