参数数量错误 ruby​​ rspec

Question

我正在尝试使用 rspec 为我的代码编写单元测试。我不断收到“错误数量的参数”错误：

class MyClass
  attr_accessor :env, :company,:size, :role, :number_of_hosts,:visability

  def initialize(env, company, size, role, number_of_hosts, visability)
    @env, @company, @size, @role, @number_of_hosts, @visability =  env, company, size, role, number_of_hosts, visability
  end




end

这是我的测试：

require_relative "../lib/MyClass.rb"

 describe MyClass do
    it "has an environment" do
        MyClass.new("environment").env.should respond_to :env
    end

    it "has a company" do
        MyClass.new("company").company.should respond_to :company
    end

...

当我运行 rspec 时，我得到：

1) MyClass has an environment
     Failure/Error: MyClass.new("environment").env.should respond_to :env
     ArgumentError:
       wrong number of arguments (1 for 6)
     # ./lib/MyClass.rb:4:in `initialize'
     # ./spec/MyClass_spec.rb:5:in `new'
     # ./spec/MyClass_spec.rb:5:in `block (2 levels) in <top (required)>'

...

我错过了什么？

Sergio 帮助感谢...但是

Sergio 的回答奏效了……尽管我还有一个问题：

给定班级：

class Team
    attr_accessor :name, :players

    def initialize(name, players = [])
        raise Exception unless players.is_a? Array

        @name = name
        raise Exception if @name && has_bad_name

        @players = players
    end

    def has_bad_name
        list_of_words = %w{crappy bad lousy}
        list_of_words - @name.downcase.split(" ") != list_of_words
    end

    def favored?
        @players.include? "George Clooney"
    end

end

和规格...

require_relative "../lib/team.rb"

describe Team do
    it "has a name" do
        Team.new("random name").should respond_to :name
    end

    it "has a list of players" do
        Team.new("random name").players.should be_kind_of Array
    end

...

测试通过而没有相同的错误...（这工作正常：Team.new("random name")）

有什么解释吗？

这是错误MyClass.new("environment")。正如你写的def initialize(env, company, size, role, number_of_hosts, visability)。所以在调用MyClass#new 方法时应该传递6 参数。但实际上你只通过了一个"environment"。因此，您得到了合法错误 - 参数数量错误（1 比 6）。
