我正在学习RSpec,似乎在教程之外的任何代码都失败了。这就是为什么我在这个问题上撞到墙上的原因。希望你们都能提供帮助。
LIB / NegotiGate
module NegotiGate
class Negotiation
def initialize(price1, price2)
@price1 = price1
@price2 = price2
end
def both_prices_equal?(price1, price2)
if @price1 == @price2
true
else
false
end
end
end
end
规格/ NegotiGate_spec.rb
describe NegotiGate do
before(:each) do
@negotiate = Negotiation.new(10,10)
end
describe "Negotiation" do
describe ".both_prices_equal?" do
context "given the sellers price is the same as the buyers highest buying price" do
it 'returns true' do
expect(@negotiate.both_prices_equal?).to be_true
end
end
end
end
end
输出:
NegotiGate

.both_prices_equal?
given the sellers price is the same as the buyers highest buying price
returns true (FAILED - 1)
Failures:
1) NegotiGate Negotiation .both_prices_equal? given the sellers price is the same as the buyers highest buying price returns true

TDD的学生非常感谢任何帮助。 干杯!

describe
块不会影响Ruby命名空间。在您的规范中,您需要将Negotiation
称为NegotiGate::Negotiation
无处不在。
但是,您在该规范中真正描述的内容不是NegotiGate
而是NegotiGate::Negotiation
,因此将describe
块更改为describe NegotiGate::Negotiation
然后您可以使用{{ 1}}简称:
described_class
顺便说一下,查看RSpec的describe NegotiGate::Negotiation do
before(:each) do
@negotiate = described_class.new(10,10)
end
describe ".both_prices_equal?" do
context "given the sellers price is the same as the buyers highest buying price" do
it 'returns true' do
expect(@negotiate.both_prices_equal?).to be_true
end
end
end
end
,这是定义多个测试中使用的变量的现代方法。实际上,在你展示的内容中,你应该在你的例子中声明一个本地,但你可能会编写更多的测试,然后值得定义let
一次。哦,并命名为negotiate
以匹配类名称将比negotiation
更好。

请尝试NegotiGate::Negotiation.new
。
