将演进应用于ScalikeJDBC内存测试DB

Question

我正在使用ScalikeJDBC和Play。我想将evolutions应用于我的Specs2测试的内存数据库。

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，因为没有应用演变。

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
)

如何才能对我的ScalikeJDBC数据库进行测试？

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，那么你必须调用Databases.inMemory(name="default", db)。
