说说rspec测试的使用

近来开始学习ruby on rails,用rspec做unit test.

An basic rspec testing requires the following steps:

1. add gem 'rspec-rails' to Gemfile and run 'bundle install'

2. run

'rails generate rspec:install

' to initialize rspec and generate spec directory. Two configuration files will be added under spec/: .rspec and spec_helper. spec_helper defines configurations required to run the test. Some more can be added
here, for example, vcr configuration. .rspec file can define how the result will be shown. You can run 'rspec --help' for more information.

3. Add a test. File name usually is class_name_spec.rb. A template can be as follows:

require 'spec_helper'
describe className do
context '...' do #optional
it "should..." do
sth.should == expected
end
end
end

4. run the test
rspec file_directory

That's all.
