Question

我在Play上使用了ScalikeJDBC。我想将Specs2测试应用到内存数据库中。

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，因为尚未应用演变。

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

application.conf 包含

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

evolutions.default / 1.sql 包含

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
)

如何获得针对ScalikeJDBC DB运行演变的测试？

Answer 1

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

例如，如果演变在evolutions/default/*.sql中，则必须调用Databases.inMemory(name="default", db)。

将演变应用于ScalikeJDBC内存中测试数据库
