认识 TestContainers

1lazy val `effectiveunitandintegrationtestinginscala` =
2  project
3    .in(file("."))
4    .settings(name := "EffectiveUnitAndIntegrationTestingInScala")
5    .settings(otherSettings)
6    .settings(dependencies)
7    .settings(integrationTestSettings)
8
9lazy val dependencies = Seq(
10  // 其他依赖项
11  libraryDependencies ++= Seq(
12    org.scalatest.scalatest,
13    com.dimafeng.`testcontainers-scala-scalatest`
14  ).map(_ % IntegrationTest)
15)
16
17lazy val integrationTestSettings = Defaults.itSettings ++ Seq(
18  IntegrationTest / fork := true
19)

提示： 尽管可以在同一个测试套件中混合使用这三种方法，但我们建议只选择其中一种。在刚开始迁移到 TestContainers-scala 时，混合使用可能有所帮助，但会增加理解不同容器之间交互关系的难度。
