ruby on rails - RSpec expect HTTP error status -

-

in example, create project, send post create project same name. should, raises activerecord::recordnotunique. want check returns 409 http status, since raises error, automatically fails test. how can check returns 409?

require 'rails_helper'  rspec.describe 'project requests', type: :request    'refuses duplicate projects'     project_1 = factorygirl.create(:project)     post '/projects', name: project_1.name     expect(response.status).to eq(409)   end end

here's rspec output:

failures:    1) project requests refuses duplicate projects      failure/error: post '/projects', name: project_1.name      activerecord::recordnotunique:        pg::uniqueviolation: error:  duplicate key value violates     unique constraint "index_projects_on_name"        detail:  key (name)=(dr. brain) exists.        : insert "projects" ("name", "created_at",     "updated_at") values ($1, $2, $3) returning "id"

below second approach. expect error, , part works fine, can't check status because never gets line. (notice how puts command doesn't output in rspec results.)

# spec/requests/project_request_spec.rb require 'rails_helper'  rspec.describe 'project requests', type: :request    'refuses duplicate projects'     project_1 = factorygirl.create(:project)     expect {       response = post '/projects', name: project_1.name       puts("this code never executed because line above fails")       expect(response.status).to eq(409)     }.to raise_error(activerecord::recordnotunique)   end  end

here's rspec output:

project requests puts should output text console.   refuses duplicate projects

that pass no matter error code returns, though test passes, doesn't test it's supposed to.

response provided rspec in context of example. rather assign value returned post new local variable, use existing method:

it 'refuses duplicate projects'   project_1 = factorygirl.create(:project)   expect { post '/projects', name: project_1.name }.to raise_error(activerecord::recordnotunique)   expect(response.status).to eq(409) end

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
