我正在使用 Test:Unit 和 Shoulda 编写我的第一个测试,所以这对我来说可能是一个简单的误解,但是给定一个不包含验证的 Pages 模型和一个测试:
#test/unit/page_test.rb
require 'test_helper'
class PageTest < ActiveSupport::TestCase
should belong_to(:site)
should validate_presence_of(:slug)
end
第二个测试按预期失败(假设模型中没有验证):
# Running tests:
[2/2] PageTest#test: Page should require slug to be set. = 0.02 s
1) Failure:
test: Page should require slug to be set. (PageTest) [/Users/Matt/.rbenv/versions/2.0.0-p0/lib/ruby/gems/2.0.0/gems/shoulda-context-1.1.1/lib/shoulda/context/context.rb:339]:
Did not expect errors to include "can't be blank" when slug is set to nil, got error:
Finished tests in 0.115436s, 17.3256 tests/s, 17.3256 assertions/s.
2 tests, 2 assertions, 1 failures, 0 errors, 0 skips
但是错误消息Did not expect errors to include "can't be blank" when slug is set to nil
似乎倒退了。不应该这样读:Expected errors to include "can't be blank"
,因为如果我正在测试的验证存在,那么当 slug 为 nil 时,您会期望验证中出现错误,即 slug“不能为空”。
如果我添加验证,测试通过,但我希望首先看到它正确失败!
另外,为什么第一次测试通过了?我的页面模型不包含belongs_to
关联!
测试很烂!:-(
