测试方法 - Ruby/RSpec 与 Java/Mockito
我正在尝试编写一些代码，如下所示，但使用 Java 而不是 Ruby，使用 Mockito 而不是 RSpec。
require 'rubygems'
require 'rspec'
class MyUtils
def self.newest_file(files)
newest = nil
files.each do |file|
if newest.nil? || (File.new(file).mtime > File.new(newest).mtime)
newest = file
end
end
newest
end
end
describe MyUtils do
it "should return the filename of the file with the newest timestamp" do
file_a = mock('file', :mtime => 1000)
file_b = mock('file', :mtime => 2000)
File.stub(:new).with("a.txt").and_return(file_a)
File.stub(:new).with("b.txt").and_return(file_b)
MyUtils.newest_file(['a.txt', 'b.txt']).should == 'b.txt'
end
end
在 RSpec 中，我可以存根 File.new，但我认为我不能在 Mockito 中执行此操作？
我是否应该使用工厂来创建 File 对象，将工厂作为依赖项注入，然后存根该工厂以进行测试？
I'm trying to write some code like the example shown below, but in Java instead of Ruby and Mockito instead of RSpec.
require 'rubygems'
require 'rspec'
class MyUtils
def self.newest_file(files)
newest = nil
files.each do |file|
if newest.nil? || (File.new(file).mtime > File.new(newest).mtime)
newest = file
end
end
newest
end
end
describe MyUtils do
it "should return the filename of the file with the newest timestamp" do
file_a = mock('file', :mtime => 1000)
file_b = mock('file', :mtime => 2000)
File.stub(:new).with("a.txt").and_return(file_a)
File.stub(:new).with("b.txt").and_return(file_b)
MyUtils.newest_file(['a.txt', 'b.txt']).should == 'b.txt'
end
end
In RSpec I can stub File.new, but I don't think I can do this in Mockito?
Should I be using a factory to create the File objects instead, inject the factory as a dependency, and then stub that factory for the tests?

这个答案包括用 Mockito 模拟 File 类，也许它会帮助。
This SO answer includes mocking the File class with Mockito, perhaps it will help.
是的，你需要注射一些东西。无论是创建文件的工厂还是文件本身，都取决于您。一旦你这样做了，你就可以在测试中模拟工厂了。
Yes, you need to inject something. Whether its a factory to create the files or the files themselves, its up to you. Once you do that, you can mock the factory in your tests.
