试图让ScalaTest工作：＆QUOT;没有测试运行＆QUOT;做＆QUOT时，MVN测试＆QUOT; [英] Trying to get ScalaTest working: "There are no tests to run" when doing "mvn test"
本文介绍了试图让ScalaTest工作：＆QUOT;没有测试运行＆QUOT;做＆QUOT时，MVN测试＆QUOT;的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
编辑：我终于得到它的工作！
它需要的JUnit的组合在pom.xml，在我.scala三个语句：
进口org.junit.runner.RunWith
进口org.scalatest.junit.JUnitRunner@RunWith（classOf [JUnitRunner]）
由于某种原因，尝试配置神火使得测试再次停止放送。
我编码的IntelliJ，试图获得通过的Maven（ MVN测试）建设进程中运行一个简单的测试ScalaTest。有没有任何错误，但遗憾的是没有测试运行任。
下面是我的.scala文件：
进口org.scalatest.FunSuite
进口org.scalatest.BeforeAndAfter类ExampleSuite扩展了BeforeAndAfter {FunSuite 之前{
的println（做安装任务......）
} 测试（检查浏览器标题的示例测试）{ VAL expected_title =平台公司
VAR actual_title =平台公司
断言（actual_title == expected_title）
} 后{
的println（做拆解工作......）
}
}
下面是Maven的输出：

解决方案
与 如果你在Maven的运行，那么你要么必须标注的测试类（ES）
@RunWith（classOf [JUnitRunner]）
这需要你有JUnit的作为一个依赖。或者你可以使用 ScalaTest Maven插件（没有用它自己虽然）。
Edit: I finally got it to work!!!
It needed a combination of JUnit in the pom.xml, and three statements in my .scala:
import org.junit.runner.RunWith
import org.scalatest.junit.JUnitRunner
@RunWith(classOf[JUnitRunner])
For some reason, trying to configure Surefire makes the tests stop running again.
I'm coding in IntelliJ, trying to get a simple ScalaTest test running via a Maven (mvn test) build process. There aren't any errors, but unfortunately no tests run either.
Here is my .scala file:
import org.scalatest.FunSuite
import org.scalatest.BeforeAndAfter
class ExampleSuite extends FunSuite with BeforeAndAfter {
before {
println("Doing setup tasks...")
}
test("Example test of checking the browser title") {
val expected_title = "Company Platform"
var actual_title = "Company Platform"
assert(actual_title == expected_title)
}
after {
println("Doing teardown tasks...")
}
}
Here's the Maven output:

解决方案
If you're running on Maven, then you'll either have to annotate your test class(es) with
@RunWith(classOf[JUnitRunner])
This would require you having JUnit as a dependency. Or you could use the ScalaTest Maven Plugin (haven't used it myself though).
