Rails 新手。尝试遵循 Michael Hartl 的教程。
尝试添加辅助方法来模拟 RSpec 测试中的日志:
describe "when the a user has logged in and attempts to visit the page" do
let(:user) { FactoryGirl.create :user }
before do
log_in user
end
it "should redirect the user to next page" do
specify { response.should redirect_to loggedin_path }
end
end
在我的 spec/support/utilities.rb 中:
def log_in user
visit root_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Log in"
cookies[:remember_token] = user.remember_token
end
错误:
Failure/Error: log_in user
NoMethodError:
undefined method `cookie_jar' for nil:NilClass
什么给了?
编辑,完整堆栈跟踪:
Index page when the a user has logged in and attempts to visit the page should redirect the user to next page
Failure/Error: log_in user
NoMethodError:
undefined method `cookie_jar' for nil:NilClass
# ./spec/support/utilities.rb:8:in `log_in'
# ./spec/features/pages/index_spec.rb:20:in `block (3 levels) in <top (required)>'
最佳答案
RSpec 对放置测试的目录非常讲究。如果您将测试放在错误的目录中,它不会自动混入设置不同类型测试的各种测试助手。看来您的设置使用的是 spec/features
,这不是经过批准的 default directory (spec/requests
、spec/integration
或 spec/api
)。
根据教程页面,我不确定他们如何设置 spec_helper.rb
文件。尽管这些示例让他们使用 spec/requests
来进行测试。
您可以强制 RSpec 通过使用以下之一来识别请求规范的另一个目录:
手动添加正确的模块到测试文件:
# spec/features/pages/index_spec.rb
require 'spec_helper'
describe "Visiting the index page" do
include RSpec::Rails::RequestExampleGroup
# Rest of your test code
context "when the a user has logged in and attempts to visit the page" do
let(:user) { FactoryGirl.create :user }
before do
log_in user
end
specify { response.should redirect_to loggedin_path }
end
end
将此包含在您的 spec/spec_helper.rb
文件中:
RSpec::configure do |c|
c.include RSpec::Rails::RequestExampleGroup, type: :request, example_group: {
file_path: c.escaped_path(%w[spec (features)])
}
end
由于这是一个教程,我建议遵循在规范文件顶部包含 require 'spec_helper'
的标准,并且您的实际 spec/spec_helper.rb
文件有 require 'rspec/rails'
小提示,您不需要将 specify
放在 it
block 中。它们互为别名,所以只用一个。
context "when the a user has logged in and attempts to visit the page" do
let(:user) { FactoryGirl.create :user }
before do
log_in user
end
# All of the following are the same
it "redirects the user to next page" do
response.should redirect_to loggedin_path
end
it { response.should redirect_to loggedin_path }
specify "redirects the user to next page" do
response.should redirect_to loggedin_path
end
specify { response.should redirect_to loggedin_path }
end
请注意,根据 capybara 的文档,您应该能够将 capybara 测试放入 spec/features
。要使其正常工作,请确保您在 spec_helper
中加载 require 'capybara/rspec'
或直接测试规范文件。
但是,查看 source ,我没有看到它们自动包含该目录的位置。您还可以尝试将标记 type::feature
添加到测试文件中的外部 describe
block 。尽管更可能的解决方案是使用 spec/requests
。
