RSpec - Expectations

您在采用旧法典或旧版本的RSpec工作时,可能会碰到旧的RSpec syntax。 如果你使用新版本的RSpec,你将看到警告。

例如,该法典有:

RSpec.describe "An RSpec file that uses the old syntax" do
   it  you should see a warning when you run this Example  do 
      (1 + 1).should eq(2) 
   end 
end

当你管理时,你将获得这样的产出:

. Deprecation Warnings:

Using `should` from rspec-expectations  old `:should` 
   syntax without exppcitly enabpng the syntax is deprecated. 
   Use the new `:expect` syntax or exppcitly enable 
	
`:should` with `config.expect_with( :rspec) { |c| c.syntax = :should }`
   instead. Called from C:/rspec_tutorial/spec/old_expectation.rb:3 :in 
   `block (2 levels) in <top (required)> .

If you need more of the backtrace for any of these deprecations to
   identify where to make the necessary changes, you can configure 
`config.raise_errors_for_deprecations!`, and it will turn the deprecation 
   warnings into errors, giving you the full backtrace.
