scalaTest runner 开始而不是 specs2 runner

Question

我的游戏项目有问题。在我的 build.sbt 中，我添加了依赖项

libraryDependencies += specs2 % Test

但是当我尝试运行带有一些参数的测试时，出现错误

testOnly SecondSpecification -- ex "test"

正如您从错误中看到的那样 - scalaTest 运行ner 启动而不是 specs2 运行ner，为什么？

Answer 1

当您尝试使用 sbt 运行测试时，specs2 和 ScalaTest 测试运行ners 都被调用。而ScalaTest在命令行参数未知时会抛出异常。

您可以通过 build.sbt

中的以下设置解决此问题

testFrameworks := Seq(TestFrameworks.Specs2)

scalaTest runner 开始而不是 specs2 runner

scalaTest runner started instead of specs2 runner

sbt

playframework

specs2
