尝试学习 Ruby 及以下是我创建的一个模块,用于测试 IO Ruby 功能。当我运行以下测试时:
subject{TestGem.new}
it 'should be_a Module' do
subject.is_a Module
end
it 'creates a config file' do
subject.init_config
File.open("program.config", "r") { |io| io.readline }.should eq "default_file.txt"
end
我得到这个错误:
Failure/Error: subject{TestGem.new}
NoMethodError:
undefined method `new' for TestGem:Module
这是我正在测试的模块。任何帮助/建议将不胜感激:)
$LOAD_PATH.unshift File.expand_path("../test_gem", __FILE__)
require 'version'
require 'hello'
module TestGem
@default_file_name
@supported_types
def initialize
default_file_name = 'default_file.txt'
supported_types = ['txt', 'pdf']
end
puts "module TestGem defined"
def self.init_config
File.open('program.config', "w") do |f|
f.write(yaml(@default_file_name))
f.write(yaml(@supported_types))
end
end
class MyFile
def self.first(filename)
File.open(filename, "r") {|f| f.readline}
end
def self.last(filename)
File.open(filename, "r")[-1]
end
end
class MyError < StandardError
puts "Standard Error"
end
end
