Question

我目前正在Sinatra / Datamapper中测试这个类

class Score 
include DataMapper::Resource

property :score, Integer

property :created_at, DateTime, :default => DateTime.now, :lazy => [:show]
property :updated_at, DateTime, :default => DateTime.now, :lazy => [:show]

belongs_to :pageant, :key => true
belongs_to :candidate, :key => true
belongs_to :category, :key => true
belongs_to :judge, :key => true

end

使用此rspec测试

it 'that can be inserted by a judge if a pageant is active' do
        score_count = Score.all.length
        post '/score', @correct_score_data
        Score.all.length.should eq score_count+1
    end

    it 'cannot be duplicated if it has been sent' do
        score_count = Score.all.length
        post '/score', @correct_score_data
        Score.all.length.should eq score_count
    end

基本上应该发生的事情是，法官只能为特定类别+候选人+选美组合发送一次得分，之后我想拒绝接下来的得分。现在当我运行它时，我得到一个IntegrityError（我期望）。我怎么告诉rspec我“希望看到这个错误”？你们也可以批评我的代码，我还在一起学习所有这些

使用expect{}.to raise_error：https://www.relishapp.com/rspec/rspec-expectations/v/2-6/docs/built-in-matchers/raise-error-matcher

我不完全理解您的规范（看起来您的应用程序状态在两个测试之间泄漏），但是像这样......

it 'cannot be duplicated if it has been sent' do
    score_count = Score.all.length
    expect { post '/score', @correct_score_data }.to raise_error(IntegrityError)
end

rspec / datamapper - 如何告诉rspec预期错误？
