Question

我的模型中有一个下面的方法，我想要存根下面的值

＆＃34; esxi_hosts = RezApi.new.get_esxi(type, vrealm_id)＆＃34;

的值为[{x: "y"}]

在rspec中执行此操作的方法是什么。

def create_esxi
if (["vRealm", "Praxis Parent vRealm", "Praxis Child vRealm"].include?(self.collection_type.try(:name)))
  esxi_hosts = []
  if(( self.parent && self.parent.parent && self.parent.collection_type.name.upcase == "POD" && self.parent.parent.collection_type.name.upcase == "DATACENTER") or ( self.parent && self.parent.parent && self.parent.parent.parent && (self.parent.collection_type.name.upcase == "RELEASE - PRAXIS" or self.parent.collection_type.name.upcase == "RELEASE - SUBSCRIPTION") && self.parent.parent.collection_type.name.upcase == "POD" && self.parent.parent.parent.collection_type.name.upcase == "DATACENTER"))
    vrealm_type = collection_type.try(:name)
    vrealm_id = "d#{self.parent.parent.instance}p#{self.parent.instance}v#{instance}"
    case vrealm_type
      when   "vRealm"
        types = ["vrealm-multitenant-dr2c", "vpc-standard"]
        types.each do |type|
          if esxi_hosts.empty?
            esxi_hosts = RezApi.new.get_esxi(type, vrealm_id)
          end
        end
      when   "Praxis Parent vRealm"
        esxi_hosts = RezApi.new.get_esxi("praxis-core", vrealm_id)
      when   "Praxis Child vRealm"
        esxi_hosts = RezApi.new.get_esxi("praxis-node-mgmt", vrealm_id)
    end
  end
  if esxi_hosts.flatten.any?
    assign_esxi(esxi_hosts)
  end
 end
end

我已经尝试过以下代码，但它没有用

      require 'spec_helper'

describe "Esxi Host creation from Rez Api" do
  let(:federation)  {create(:federation_collection, parent_id: nil, name: "Test", usage: "Tech Ops hosted in Vmware Data Centers", owner: "--", date_from: "2015-08-26", date_to: nil, collection_type_id: 2, zone_name: "se.vpc.vmw")}
  let(:datacenter) {create(:datacenter_collection, name: "Datacenter", parent_id: federation.id)}
  let(:pod)  {create(:pod_collection, parent_id: datacenter.id)}
  let(:fqdn) {"d2p1s0ch10srv0v101-esx0.se.vpc.vmw"}
  let(:vrealm1)  {create(:vrealm_collection, name: "vRealm1", parent_id: pod.id)}
  let(:vrealm2) {create(:vrealm_collection, name: "vRealm2", parent_id: pod.id)}


  context "When response has esxi hosts " do
    let(:rez_response) {[{"esx0"=>{"nodefqdn"=>"d2p1s0ch10srv0.se.vpc.vmw","fqdn"=>"d2p1s0ch10srv0v101-esx0.se.vpc.vmw","vmk0"=>{"pg_name"=>"d2p1v101-esx-pg-1062","ip_addr"=>"10.141.112.71","netmask"=>"255.255.255.0",},"vmk1"=>{"pg_name"=>"d2p1pod-sto-pg-17","ip_addr"=>"172.16.160.51","netmask"=>"255.255.252.0"},"vmk2"=>{"pg_name"=>"d2p1v101-ftx-pg-1063","ip_addr"=>"172.16.165.126","netmask"=>"255.255.255.0"}}}]}
    subject {RezApi.new}
    it "should create esxi hosts" do
      allow(subject).to receive(:get_esxi).with("type", "101").and_return(rez_response)
      expect(subject).to receive(:get_esxi).with("type", "101").and_return(rez_response)
      vrealm1.create_esxi
      vrealm1.resources.map(&:fqdn).should include(fqdn)
    end
  end

end

获得以下错误

     Failures:

  1) Esxi Host creation from Rez Api When response has esxi hosts  should create esxi hosts
     Failure/Error: expect(subject).to receive(:get_esxi).with("type", "101").and_return(rez_response)
       (#<RezApi:0xc26d69c>).get_esxi("type", "101")
           expected: 1 time with arguments: ("type", "101")
           received: 0 times

Answer 1

  subject { RezApi.new }

  context "....." do
    it "....." do
      allow(subject).to receive(:get_esxi).with("type", "101").and_return({x: "y"})
      expect(subject).to receive(:get_esxi).with("type", "101").and_return({x: "y"})
    end
  end

因此，您更新的测试代码应为：

describe "Esxi Host creation from Rez Api" do

  let(:federation)  {create(:federation_collection, parent_id: nil, name: "Test", usage: "Tech Ops hosted in Vmware Data Centers", owner: "--", date_from: "2015-08-26", date_to: nil, collection_type_id: 2, zone_name: "se.vpc.vmw")}
  let(:datacenter) {create(:datacenter_collection, name: "Datacenter", parent_id: federation.id)}
  let(:pod)  {create(:pod_collection, parent_id: datacenter.id)}
  let(:fqdn) {"d2p1s0ch10srv0v101-esx0.se.vpc.vmw"}
  let(:vrealm1)  {create(:vrealm_collection, name: "vRealm1", parent_id: pod.id)}
  let(:vrealm2) {create(:vrealm_collection, name: "vRealm2", parent_id: pod.id)}

  context "When response has esxi hosts " do
    let(:rez_response) {[{"esx0"=>{"nodefqdn"=>"d2p1s0ch10srv0.se.vpc.vmw","fqdn"=>"d2p1s0ch10srv0v101-esx0.se.vpc.vmw","vmk0"=>{"pg_name"=>"d2p1v101-esx-pg-1062","ip_addr"=>"10.141.112.71","netmask"=>"255.255.255.0",},"vmk1"=>{"pg_name"=>"d2p1pod-sto-pg-17","ip_addr"=>"172.16.160.51","netmask"=>"255.255.252.0"},"vmk2"=>{"pg_name"=>"d2p1v101-ftx-pg-1063","ip_addr"=>"172.16.165.126","netmask"=>"255.255.255.0"}}}}

    subject { RezApi.new }

    it "should create esxi hosts" do
      allow(subject).to receive(:get_esxi).with("vrealm-multitenant-dr2c", "101").and_return(rez_response)
      expect(subject).to receive(:get_esxi).with("vrealm-multitenant-dr2c", "101").and_return(rez_response)
      vrealm1.create_esxi
      vrealm1.resources.map(&:fqdn).should include(fqdn)
    end
  end
end

Answer 2

使用以下代码

RezApi.any_instance.stub(:get_esxi).with("vrealm-multitenant-dr2c", "101").and_return(success_response)

我怎样才能在rspec模型中使用stub方法
