[英]RSPEC test generate csv
def create_csv(some_hash)
CSV.open("public/generated_file.csv", "wb") do |row|
csv << ['Time', Time.now]
some_hash.to_a.each { |data| row << data }
end
end
How do I test that this method actually creates a file so I could check an output?如何测试此方法是否实际创建了一个文件,以便我可以检查输出?
Here is a link to the rspec docs. 这是 rspec 文档的链接。 It uses to_be_an_existing_file
to check for presence.它使用to_be_an_existing_file
来检查是否存在。
require 'spec_helper'
RSpec.describe 'Check if file exists and is file', :type => :aruba do
let(:file) { 'public/generated_file.csv' }
before { create_csv({...}) }
after { FileUtils.rm_rf(Dir["#{Rails.root}/public/generated_file.csv"]) }
it { expect(file).to be_an_existing_file }
end
