Question

我在凤凰应用程序中进行了以下测试：

machineAddresses <- list(
  list(host='rserver1',user='ubuntu',
       ncore=11),
  list(host='rserver2',user='ubuntu',
       ncore=11)
)

spec <- lapply(machineAddresses,
               function(machine) {
                 rep(list(list(host=machine$host,
                               user=machine$user)),
                     machine$ncore)
               })

spec <- unlist(spec,recursive=FALSE)

library("doParallel")
cl <- makeCluster(type='PSOCK',master=primary,spec=spec)
registerDoParallel(cl)
#this is purely based on your need , there are many articles on how to run parallel loops , the focus is mainly on multiple hosts
clusterExport(cl, varlist=ls(.GlobalEnv)) 

print(cl)
##run your commands
stopCluster(cl)

这些行在测试中重复：

defmodule TattooBackend.Web.API.V1.PasswordControllerTest do
  use TattooBackend.Web.ConnCase, async: true
  use Bamboo.Test

  alias TattooBackend.Web.Endpoint
  alias TattooBackend.Accounts.Account
  alias TattooBackend.Repo
  alias Phoenix.Token
  alias Comeonin.Bcrypt
  import TattooBackend.AuthenticationRequiredTest

  test "without passwords", %{conn: conn} do
    account = insert(:account)
    token   = Token.sign(Endpoint, "account_id", account.id)

    conn =
      conn
      |> put_req_header("authorization", "#{token}")
      |> post(api_v1_password_path(conn, :create))

    assert json_response(conn, 422)
  end

  test "with wrong password confirmation", %{conn: conn} do
    account = insert(:account)
    token   = Token.sign(Endpoint, "account_id", account.id)
    params  = %{password: "new-password", password_confirmation: "password"}

    conn =
      conn
      |> put_req_header("authorization", "#{token}")
      |> post(api_v1_password_path(conn, :create, params))

    assert json_response(conn, 422)
  end
end

知道如何让它变干吗？

如果要在所有测试中执行这两行，可以将重复代码放在setup回调中，然后使用模式匹配来获取每个测试中的那些：

defmodule TattooBackend.Web.API.V1.PasswordControllerTest do
  ...

  setup do
    account = insert(:account)
    token   = Token.sign(Endpoint, "account_id", account.id)
    [account: account, token: token]
  end

  test "without passwords", %{conn: conn, account: account, token: token} do
    conn =
      conn
      |> put_req_header("authorization", "#{token}")
      |> post(api_v1_password_path(conn, :create))

    assert json_response(conn, 422)
  end

  test "with wrong password confirmation", %{conn: conn, account: account, token: token} do
    params  = %{password: "new-password", password_confirmation: "password"}

    conn =
      conn
      |> put_req_header("authorization", "#{token}")
      |> post(api_v1_password_path(conn, :create, params))

    assert json_response(conn, 422)
  end
end

setup将在每次测试之前执行其代码，然后将account和token传递给每个测试。
