params在测试Rails辅助方法时设置哈希值？我想设置params[:search] = 'my keyword search'在我的帮助方法中使用,然后从it示例块中调用它.
require 'rails_helper'
describe BooksHelper do
describe "#page_title_helper" do
let(:params) { {search: 'my keyword search'} }
it "should read the params hash" do
expect(helper.params[:search]).to eq "my keyword search"
end
end
end
BooksHelper
def title_helper
if params[:search]
"Books related to #{params[:search]}"
else
"All Books"
end
end
end
我有一个rake任务,根据环境防范危险的Rails rake rasks.它工作正常.当我在RSpec中测试每个单独的危险方法时,测试通过.当我连续测试多个时,对于多个环境,测试在第一个测试后失败.例如,即使我为同一危险动作多次运行测试rake db:setup,它也只会在第一次通过.如果我将测试作为单独的it语句运行,每个危险操作一个,只有前两个将通过(有4个).
如何在这里使RSpec正常运行,并在套件中运行时通过所有测试？
耙子任务
# guard_dangerous_tasks.rake
class InvalidTaskError < StandardError; end
task :guard_dangerous_tasks => :environment do
unless Rails.env == 'development'
raise InvalidTaskError
end
end
%w[ db:setup db:reset ].each do |task|
Rake::Task[task].enhance ['guard_dangerous_tasks']
end
RSpec测试
require 'spec_helper'
require 'rake'
load 'Rakefile'
describe 'dangerous_tasks' do
context 'given a production environment' do
it 'prevents dangerous tasks' do
allow(Rails).to receive(:env).and_return('production')
%w[ db:setup db:reset ].each do |task_name|
expect { Rake::Task[task_name].invoke }.to raise_error(InvalidTaskError)
end
end
end
context 'given a test …任何一个可以请解释一下我一下的区别be_true,并be true用简单的例子红宝石英寸 我也见过be_true并且be_false改为be_truthy和be_falsey
我有一个'be true'工作的例子,但当我尝试使用'be_true'或'be_truthy'规格失败.
我使用的是RSpec 3.1.7版
由于我更新了我的Gemfile并转移到rspec 3,在许多测试中,我收到错误:way:
it "should reject attribute that are too short" do
short = "a" * 3
hash = @attr.merge(:details => short)
Deal.new(hash).should have(1).error_on(:details)
end
我收到这个错误:
Failure/Error: Deal.new(hash).should have(1).error_on(:details)
NoMethodError:
undefined method `have' for #<RSpec::ExampleGroups::Deal_2::TestsOnDealsModelsValidations>
我读过我现在应该使用"expect"而不是应该但是have(1).error_on,我应该如何编写它以符合rspec 3？
我尝试了以下但它仍然无法正常工作:
it "should reject attribute that are too short" do
short = "a" * 3
hash = @attr.merge(:details => short)
expect(Deal.new(hash).error_on(:details).size).to eq(1)
end
it 'should be an array and not be empty' do
pending
expect(a.class).to be(Array)
expect(a.empty?).to be(false)
expect(a.first.class).to be(ExampleClass)
end
当我运行rspec时:
Failures:
1) should be an array and not be empty FIXED
Expected pending 'No reason given' to fail. No Error was raised.
# ./spec/example_spec.rb:19
任何想法为什么这被列为失败？
我有一个organization具有属性的对象name, doing_business_as.我需要验证它name是不一样的doing_business_as.
# app/models/organization.rb
class Organization < ActiveRecord::Base
validate :name_different_from_doing_business_as
def name_different_from_doing_business_as
if name == doing_business_as
errors.add(:doing_business_as, "cannot be same as organization name")
end
end
end
我有一个匹配的rspec文件来验证这个:
# spec/models/organization_spec.rb
require "rails_helper"
describe Organization do
it "does not allow NAME and DOING_BUSINESS_AS to be the same" do
organization = build(:organization, name: "same-name", doing_business_as: "same-name")
expect(organization.errors[:doing_business_as].size).to eq(1)
end
end
然而,当我运行规范时,它失败了,这就是我得到的:
$ rspec spec/models/organization_spec.rb
Organization
does not allow NAME and DOING_BUSINESS_AS to be …我可以测试参数是否传递如下:
RSpec.describe do
it do
obj = double
expect(obj).to receive(:method).with(1, 2, 3)
obj.method(1, 2, 3)
end
end
我该怎么做一个块参数？我的理想代码:
RSpec.describe do
it do
obj = double
proc = Proc.new{}
expect(obj).to receive(:method).with(1, 2, 3).with_block(proc)
obj.method(1, 2, 3, &proc)
end
end
我在应用程序配置中定义了一个选项.我要测试的类是在gem中定义的(不是由我编写的).我想重新开课:
Myclass.class_eval do
if Rails.application.config.myoption=='value1'
# some code
def self.method1
end
else
# another code
def self.method2
end
end
end
我想使用RSpec 3测试此代码:
# myclass_spec.rb
require "rails_helper"
RSpec.describe "My class" do
allow(Rails.application.config).to receive(:myoption).and_return('value1')
context 'in taxon' do
it 'something' do
expect(Myclass).to respond_to(:method1)
end
end
end
如何在运行重新打开类的代码之前存根应用程序配置值.
Serverspec站点的"高级提示"部分显示了使用相同测试集测试多个主机的示例.我已经建立了一个我自己的例子(https://gist.github.com/neilhwatson/81249ad393800a76a8ad),但是有问题.
第一个问题是测试在第一次失败时停止,而不是继续通过该批次并保持计数.第二个是故障输出并不表示故障发生在哪个主机上.我该怎么做才能解决这些问题并为所有主机生成最终报告？
我正在创造
bundler gem --test=rspec MyGem.
我正在获取存储库结构.
当我尝试运行rspec代码时,我收到以下错误:
`require': cannot load such file -- spec_helper (LoadError)
然后我尝试应用require relative但我仍然收到错误:
