我想从模型开始将现有的 rails 应用程序从 rspec 切换到 minitest。因此我创建了一个文件夹test。在里面我创建了一个文件minitest_helper.rb，其内容如下：

require "minitest/autorun"

ENV["RAILS_ENV"] = "test"

和models包含的文件夹forum_spec.rb：

require "minitest_helper"

describe "one is really one" do
  before do
    @one = 1
  end

  it "must be one" do
    @one.must_equal 1
  end
end

现在我可以运行ruby -Itest test/models/forum_spec.rb以下结果：

Loaded suite test/models/forum_spec
Started
.
Finished in 0.000553 seconds.

1 tests, 1 assertions, 0 failures, 0 errors, 0 skips

Test run options: --seed 12523

那很好。但现在我希望加载环境，并将以下行添加到minitest_helper.rb（从 rspec 的等效文件复制）：

require File.expand_path("../../config/environment", __FILE__)

现在我再次运行它，结果如下：

Loaded suite test/models/forum_spec
Started

Finished in 0.001257 seconds.

0 tests, 0 assertions, 0 failures, 0 errors, 0 skips

Test run options: --seed 57545

测试和断言消失了。这可能是什么原因？

Since you are switching the app from rspec, you most probably have rspec gem in test environment specified in Gemfile, something like:

group :test do
  gem 'rspec'
end

When you load up the 'test' environment with ENV["RAILS_ENV"] = "test", you are loading up the rspec, which defines its own describe method and overrides the one defined by minitest.

So there are 2 solutions here: 1. Remove rspec gem from test environment 2. If you still want to run rspecs while switching to minitest, you can leave the 'test' environment alone and define another test environment specifically for minitest. Let's call it minitest - copy the config/environment/test.rb to config/enviroment/minitest.rb, define database for minitest environment, and update minitest_helper to set RAILS_ENV to 'minitest':

$ cp config/environments/test.rb config/environments/minitest.rb

(a portion of) config/database.yml: 

minitest:
  adapter: sqlite3
  database: db/test.sqlite3
  pool: 5
  timeout: 5000

test/minitest_helper.rb:

ENV["RAILS_ENV"] = "minitest"
require File.expand_path("../../config/environment", __FILE__)
require "minitest/autorun"
