[英]How to test obtaining a list of files within a directory using RSpec?
I'm pretty new to the world of RSpec. 我对RSpec的世界很陌生。 I'm writing a RubyGem that deals with a list of files within a specified directory and any sub-directories.
我正在写一个RubyGem,它处理指定目录和任何子目录中的文件列表。 Specifically, it will use
Find.find
and append the files to an Array for later output. 具体来说,它将使用
Find.find
并将文件附加到数组以供以后输出。
I'd like to write a spec to test this behaviour but don't really know where to start in terms of faking a directory of files and stubbing Find.find
etc. This is what little I have so far: 我想编写一个规范来测试此行为,但实际上不知道从伪造文件目录和对
Find.find
等进行存根的Find.find
。这是我到目前为止所没有的:
it "should return a list of files within the specified directory" do
end
Any help much appreciated! 任何帮助,不胜感激!
您可以使用fakeFS gem。
I don't think you need to test the library, but if you have a method like 我认为您不需要测试库,但是如果您有类似的方法
def file_names
files = []
Find.find(Dir.pwd){|file| files << file}
........
end
you can stub the find method to return a list of files like so 您可以存根find方法以返回文件列表,如下所示
it "should return a list of files within the specified directory" do
Find.stub!(:find).and_return(['file1', 'file2'])
@object.file_names
end
or if you want to set the expectation then you can do 或者,如果您要设定期望,则可以
it "should return a list of files within the specified directory" do
Find.should_receive(:find).and_return(['file1', 'file2'])
@object.file_names
end
