我是一个使用 minitest 的测试新手，并且很难开始。我想知道为什么每次我运行测试时都会重新创建数据库。我看过的示例视频似乎并非如此（例如 minitest 上的这个 railscast）。我的设置不正确吗？每次都应该这样吗？

每次我运行时，rake minitest:models我都会在测试运行之前看到以下内容（缩短了，因为它像 500 行）

rake minitest:models
Connecting to database specified by database.yml
   (0.7ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" 
   (379.5ms)  DROP DATABASE IF EXISTS "mf_test"
   (239.8ms)  CREATE DATABASE "mf_test" ENCODING = 'utf8'
NOTICE:  CREATE TABLE will create implicit sequence "admins_id_seq" for serial column "admins.id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "admins_pkey" for table "admins"
   (7.8ms)  CREATE TABLE "admins" ("id" serial primary key, "email" character varying(255) DEFAULT '' NOT NULL, "encrypted_password" character varying(255) DEFAULT '' NOT NULL, "reset_password_token" character varying(255), "reset_password_sent_at" timestamp, "remember_created_at" timestamp, "sign_in_count" integer DEFAULT 0, "current_sign_in_at" timestamp, "last_sign_in_at" timestamp, "current_sign_in_ip" character varying(255), "last_sign_in_ip" character varying(255), "created_at" timestamp NOT NULL, "updated_at" timestamp NOT NULL) 
   (1.5ms)  CREATE UNIQUE INDEX "index_admins_on_email" ON "admins" ("email")
