尝试为Scala中Play web应用程序的Slick数据库创建单元测试

import org.scalatestplus.play._
import play.api.test._
import play.api.test.Helpers._
import play.api.inject.guice.GuiceApplicationBuilder
import play.api.db.slick.DatabaseConfigProvider
import slick.jdbc.JdbcProfile

class SlickDatabaseSpec extends PlaySpec with OneAppPerTest {

  // 创建一个内存数据库的配置
  val dbConfig = DatabaseConfigProvider.get[JdbcProfile](app)
  val db = dbConfig.db

  // 在每个测试之前创建数据库表
  override def beforeEach(): Unit = {
    val createTableQuery = TableQuery[YourTable]
    db.run(createTableQuery.schema.create)
  }

  // 在每个测试之后删除数据库表
  override def afterEach(): Unit = {
    val dropTableQuery = TableQuery[YourTable]
    db.run(dropTableQuery.schema.drop)
  }

  "Your Slick database" should {

    "insert a record" in {
      val insertQuery = TableQuery[YourTable] += YourRecord(...)
      val result = db.run(insertQuery)
      result.futureValue mustBe 1
    }

    "retrieve records" in {
      val insertQuery = TableQuery[YourTable] += YourRecord(...)
      db.run(insertQuery)

      val selectQuery = TableQuery[YourTable].result
      val result = db.run(selectQuery)
      result.futureValue must have length 1
    }

    // 其他测试用例...

  }

  // 定义一个示例的数据库表和记录
  case class YourRecord(...)
  class YourTable(tag: Tag) extends Table[YourRecord](tag, "your_table") {
    // 定义表结构
    // ...
  }
