Rails Rake 测试：运行测试时出错：单位！ #<RuntimeError: 命令失败，状态为

Question

Errors running test:units! #<RuntimeError: Command failed with status (1): [ruby -I"lib:test" -I"/Users/jake/.rvm/gems/ruby-1.9.3-p286/gems/rake-10.0.2/lib" "/Users/jake/.rvm/gems/ruby-1.9.3-p286/gems/rake-10.0.2/lib/rake/rake_test_loader.rb" "test/unit/**/*_test.rb" ]>

这是否意味着我的单元测试文件有问题，或者我的模型有问题？或者两者都可以？

下面的完整跟踪。

编辑

此错误仅在 rake 返回错误时显示。如果没有错误，运行测试的这个错误也不会出现......好奇和好奇......

Answer 1

这是您的一项测试未通过时的标准响应。我用一个模型创建了一个空项目，并添加了以下单元测试：

require 'test_helper'

class BlobTest < ActiveSupport::TestCase
  test "test errors" do
    assert false
  end
end

然后我运行它：

dhcp168:unittest pmorse$ rake test
Run options: 

# Running tests:

我怀疑这是因为 Test::Unit 向 Rake 返回了一个错误代码，而 Rake 正在返回此输出，这使得它看起来像是有问题。 （而且我想出了点问题：你的测试没有通过。）

Answer 2

我也遇到了这个问题。

4 小时后进行调查。我发现我定义了一个假设数据库中必须有记录的范围。喜欢

scope :has_no_rep, where('country_id != ?', Country.global.id)`

def self.global
  Country.where(:code => GLOBAL_CODE).first
end

然后在初始化测试环境期间“加载”此范围时。将引发一个错误，这将导致问题..

所以我对这个问题的建议是。为您的开发环境设置一个新的空数据库（实际上。越类似测试的环境越好）。并尝试rails s。这可以帮助您定位错误。而不是模棱两可的“命令失败，状态为 X”
