【问题描述】：
This question 询问如何使用 sbt 和 ScalaTest 获取 html 报告。答案参考了 Scala 测试 2.0，似乎不适用于 ScalaTest 3.0
我通过
声明ScalaTest lazy val scalaTest = Seq("org.scalatest" %% "scalatest" % "3.0.8" % "test",
"org.scalactic" %% "scalactic" % "3.0.8",
"org.scalamock" %% "scalamock" % "4.4.0" % Test)
然后使用它
ThisBuild / Test / testOptions += Tests.Argument(TestFrameworks.ScalaTest, "-h", "target/test-reports")
和
lazy val foo = (project in file("foo")).
settings(libraryDependencies ++= scalaTest)
这失败了

[error] at scala.collection.IterableLike.foreach$(IterableLike.scala:73)

...
问题建议使用"test->*" 进行测试声明。尝试
lazy val scalaTest = Seq("org.scalatest" %% "scalatest" % "3.0.8" % "test->*" excludeAll (
ExclusionRule(organization="org.junit", name="junit")),
"org.scalamock" %% "scalamock" % "4.4.0" % Test
)
反而失败了

随后出现的错误看起来像是不存在 FlatSpec 的隐式转换，并且可能是上述后续错误。
ScalaTest 3.0 有没有办法做到这一点？
