用ScalaTest 3.0生成html报表

Question

This question询问如何使用sbt和ScalaTest获取html报告。答案参考Scala test2.0，对于我的ScalaTest 3.0似乎不起作用

我通过以下方式声明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)

然后通过以下方式使用它

 ThisBuild / Test / testOptions += Tests.Argument(TestFrameworks.ScalaTest, "-h", "target/test-reports")

和

lazy val foo = (project in file("foo")).
    settings(libraryDependencies ++= scalaTest)

这将失败，原因是

[error] java.lang.NoClassDefFoundError: org/pegdown/PegDownProcessor

[error]     at org.scalatest.tools.ReporterFactory.createHtmlReporter(ReporterFactory.scala:192)

[error]     at scala.collection.IterableLike.foreach$(IterableLike.scala:73)
[error]     at org.scalatest.tools.ReporterConfigurations.foreach(ReporterConfiguration.scala:42)
...

这个问题建议使用"test->*"进行测试声明。正在尝试

    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
        )

取而代之的是失败

随后出现的错误看起来像是FlatSpec的隐式转换不存在，并且可能是上述错误的后续错误。

有没有办法在ScalaTest 3.0中做到这一点？

Answer 1

尝试像这样添加pegdown依赖项

libraryDependencies += "org.pegdown" % "pegdown" % "1.6.0" % Test

注意:根据resolve #1201 replace pegdown with flexmark-java #1229，在ScalaTest 3.1.x中，pegdown被替换为flexmark-java
