Question

我有一个scala-play-slick应用程序，并且正在使用Google guice进行依赖项注入。光滑版本3.0.3 我的存储库如下所示：

@Singleton
class Repository @Inject()(dbConfigProvider: DatabaseConfigProvider)(
    implicit ec: ExecutionContext) {

  private val dbConfig = dbConfigProvider.get[JdbcProfile]

  import dbConfig._
  import profile.api._

  private class MyTable(tag: Tag) extends Table[ModelObject](tag, "TableName") {

    def id = column[Int]("id", O.PrimaryKey, O.AutoInc)

    def * =
      (id) <> ((ModelObject.apply _).tupled, ModelObject.unapply)
  }

  private val myTable = TableQuery[MyTable]

  def getAll: Future[Seq[ModelObject]] = db.run {
    myTable.result
  }
// remaining code

现在，要对代码进行单元测试，我有以下代码

class RepositoryTest extends FunSuite with Matchers with BeforeAndAfterEach {

  private var databaseConfigProvider : DatabaseConfigProvider = _
  private var repository : Repository = _

  override def beforeEach(): Unit = {
    databaseConfigProvider = mock(classOf[DatabaseConfigProvider])
    repository = new Repository(databaseConfigProvider)
  }

  test("should get all the model object"){
    val result = usersRepository.getAll(userRequest).await
    result shouldBe modelObjects
  }

}

在运行测试用例时，我得到了Nullpointer异常

java.lang.NullPointerException was thrown.
java.lang.NullPointerException

在getAll方法的db.run行中。现在我的问题是，我应该如何模拟MyTable以避免空指针异常。

任何指针都将非常有帮助。在此先感谢!!!

无法模拟光滑的表
