我正在尝试使用rspec为我的代码编写单元测试。我不断收到一个 “错误的参数数目” 错误:错误的参数数ruby rspec
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
这里是我的测试:
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的,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?
编辑
塞尔吉奥帮助感谢...但是
Sergio的回答工作...虽然我仍然有进一步的问题:
鉴于类别:
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
个
...
测试通过,而不同样的错误...(这工作正常:Team.new( “随机名称”))
任何解释?
您遗漏了另外5个构造函数的参数。 –
你的意思是,MyClass.new(“company”,“blah”,“blah”,“blah”,“blah”)? – fatu
是啊,类似的东西 –
