將演變應用於ScalikeJDBC內存中測試數據庫

Question

我在Play上使用了ScalikeJDBC。 我想對我的Specs2測試將演化應用於內存數據庫。

import org.specs2.mutable.Specification
import org.specs2.specification.BeforeAfterAll
import play.api.db.{Database, Databases}
import play.api.db.evolutions.Evolutions
import scalikejdbc.ConnectionPool.DEFAULT_NAME
import scalikejdbc.{ConnectionPool, DataSourceConnectionPool}

import scalikejdbc.{AutoSession, _}

class PaymentRepoSpec extends Specification with BeforeAfterAll {

  private var database: Option[Database] = None

  def beforeAll(): Unit = {
    database = Some(Databases.inMemory(
      name = "payment-repo",
      urlOptions = Map("MODE" -> "PostgreSQL", "DATABASE_TO_UPPER" -> "FALSE"),
      config = Map()
    ))
    database.foreach(Evolutions.applyEvolutions(_))
    database.foreach(db => ConnectionPool.add(DEFAULT_NAME, new DataSourceConnectionPool(db.dataSource)))
  }

  def afterAll(): Unit = {
    database.foreach(Evolutions.cleanupEvolutions(_))
    database.foreach(_.shutdown())
  }

  "fruitcakes" should {
    "be delicious" >> {

      import scalikejdbc._

      DB.readOnly { implicit s =>
        sql"""select id from payments"""
          .map(_.int(1)).list().apply().foreach(println)
      }
      ok
    }
  }
}

這失敗了，因為尚未應用演變。

org.h2.jdbc.JdbcSQLException: Table "payments" not found; SQL statement:
select id from payments [42102-192]

application.conf包括

modules.enabled += "scalikejdbc.PlayModule"
modules.disabled += "play.api.db.DBModule"

evolutions.default / 1.sql包括

CREATE TABLE payments(
    id                  SERIAL PRIMARY KEY,
    source              CHAR(56) NOT NULL,
    destination         CHAR(56) NOT NULL,
    code                VARCHAR(12) NOT NULL,
    issuer              CHAR(56),
    units               NUMERIC NOT NULL,
    received            TIMESTAMP NOT NULL,
    scheduled           TIMESTAMP NOT NULL,
    submitted           TIMESTAMP,
    status              VARCHAR(9) NOT NULL CHECK (status IN ('pending', 'submitted', 'failed', 'succeeded')),
    op_result           VARCHAR(64)
);

（這在運行應用程序時有效）

build.sbt包括

libraryDependencies ++= Seq(
  guice, evolutions, jdbc, specs2 % Test,
  "io.github.synesso" %% "scala-stellar-sdk" % "0.5.1",
  "com.nrinaudo" %% "kantan.csv-generic" % "0.4.0",
  "com.h2database" % "h2" % "1.4.192",
  "org.postgresql" % "postgresql" % "42.2.5",
  "org.scalikejdbc" %% "scalikejdbc" % "3.3.0",
  "org.scalikejdbc" %% "scalikejdbc-config" % "3.3.0",
  "org.scalikejdbc" %% "scalikejdbc-play-initializer" % "2.6.0-scalikejdbc-3.3",
  "org.webjars.npm" % "bulma" % "0.7.2",
  "org.webjars" % "font-awesome" % "5.6.3",
  "org.specs2" %% "specs2-scalacheck" % "4.3.6" % Test
)

如何獲得測試以對我的ScalikeJDBC DB運行演變？

Answer 1

Databases.inMemory的參數name必須與evolutions下的文件夾匹配。

例如，如果演變是在evolutions/default/*.sql ，則必須調用Databases.inMemory(name="default", db) 。
