ruby - how to use tags within examples for minitest

问题

I have

require 'minitest/spec'
require 'minitest/autorun'
require 'minitest/tags'
require 'rspec/expectations'

describe "One happy and one sad test", :happy do
  include RSpec::Matchers

  it "it is true" do
    expect(true).to be true
  end 
  it "it is false" do
    expect(false).to be true
  end 
end

and the describe tag works but I can't add a tag to the it, as in

it "it is true", :happy do
  expect(true).to be true
end

without getting:

$ ruby test_example.rb

...1: from test_example.rb:9:in `block in <main>'

.../minitest-5.11.3/lib/minitest/spec.rb:212:in `it':
wrong number of arguments (given 2, expected 0..1) (ArgumentError)

I have the minitest-tags gem in my Gem file and have bundled

回答1:

The minitest-tags gem does not accept tags as additional arguments, instead they are given in the title text:

it "does stuff(some,tags)"

If however you want more describe-like tags, then I think you want to use minispec-metadata instead:

it "does stuff", :some, :tags

Then you can run selected tests using the --tag option:

$ ruby test_example.rb --tag some --tag tags

Note that the minitest-tags gem is quite outdated, and it will conflict with minispec-metadata if both are installed at the same time! I recommend uninstalling minitest-tags, and going with minispec-metadata instead.

Note from OP - So I ended up having:

require 'minitest/spec'
require 'minitest/autorun'
require 'minispec-metadata'
require 'rspec/expectations'

describe "One happy and one sad test" do
  include RSpec::Matchers

  it "is is true", :happy do
    expect(true).to be true
  end 
  it "it is false", :sad do
    expect(true).to be true
  end 
end
