Question

我有一个新的repo（非rails）和rspec 2.8.0。

由于一些奇怪的原因，我无法使用expect语法。

这个荒谬的规范：

require "spec_helper"

describe "The Truth" do

  it "is true" do
    expect(true).to be_true
  end
end

导致：

Failure/Error: expect(true).to be_true
     ArgumentError:
       wrong number of arguments (1 for 0)

spec_helper

RSpec.configure do |config|
  config.treat_symbols_as_metadata_keys_with_true_values = true
  config.run_all_when_everything_filtered = true
  config.filter_run :focus

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = 'random'

  config.expect_with :rspec do |c|
    c.syntax = :expect
  end

end

Answer 1

这里说的是期望语法来自rspec 2.11，所以我猜2.8是旧的http://myronmars.to/n/dev-blog/2012/06/rspecs-new-expectation-syntax

Rspec 2.8.0，期望（某事）导致ArgumentError：错误的参数数量（1表示0）
