我在 Play 中使用 ScalikeJDBC。我想为我的 Specs2 测试将进化应用到内存数据库。

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
    }
  }
}

这失败了，因为没有应用进化。

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)
);

（这在运行应用程序时有效）

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
)

如何获得测试以针对我的 ScalikeJDBC DB 运行演变？

namein的参数Databases.inMemory必须与 下的文件夹匹配evolutions。

例如，如果进化在 中evolutions/default/*.sql，那么您必须调用Databases.inMemory(name="default", db)。
