你好!
我正在尝试使用Rspec测试一个控制器方法,如下所示:
def email_customer
@quote = Quote.find(params[:quote_id])
hash = {
quote: @quote,
body: params[:email_body],
subject: params[:email_subject]
}
QuoteMailer.email_customer(hash).deliver
redirect_to edit_quote_path params[:quote_id]
end
对应的规范如下:
describe 'POST email_customer' do
let!(:quote) { create(:valid_quote) }
it 'assigns the quote and sends the customer an email' do
post :email_customer, quote_id: quote.id
expect(assigns(:quote)).to eq(quote)
expect(QuoteMailer).to receive(:email_customer).with(an_instance_of(Hash)).and_return( double('QuoteMailer', deliver: true))
end
end
当测试运行时,我收到了这个消息:
Failure/Error: expect(QuoteMailer).to receive(:email_customer).with(an_instance_of(Hash)).and_return( double('QuoteMailer', deliver: true))
(<QuoteMailer (class)>).email_customer(an instance of Hash)
expected: 1 time with arguments: (#<RSpec::Matchers::AliasedMatcher:0x0000000c2b1e28 @description_block=#<Proc:0x00000009816268@/home/david/.rvm/gems/ruby-2.1.1/gems/rspec-expectations-3.0.0.beta2/lib/rspec/matchers.rb:231 (lambda)>, @base_matcher=#<RSpec::Matchers::BuiltIn::BeAnInstanceOf:0x0000000c2b1e50 @expected=Hash>>)

# ./spec/controllers/quotes_controller_spec.rb:28:in `block (3 levels) in <top (required)>'
我在控制器方法和发送邮件方法中使用了puts语句,以便知道它会运行并调用正确的方法,但我不确定为什么它失败了。我猜测这是一个愚蠢的语法错误,但我不确定。非常感谢您的帮助!

之前编写你的expect
