Question

ScalaTest运行器应支持按标签包含或排除测试，但我无法使其工作。我究竟做错了什么？详情如下。

在另一个空目录中，给出build.sbt：

libraryDependencies += "org.scalatest" %% "scalatest" % "2.1.0" % "test"

和src / test / scala / Test.scala：

class Test extends org.scalatest.FunSuite {
  test("fast") {
    assertResult(4)(2 + 2) }
  test("slow", org.scalatest.tagobjects.Slow) {
    assertResult(40)(20 + 20) }
}

然后：

% sbt
[info] Set current project to bug (in build file:/Users/tisue/bug/)
> show sbtVersion
[info] 0.13.1
> test
[info] Compiling 1 Scala source to /Users/tisue/bug/target/scala-2.10/test-classes...
[info] Test:
[info] - fast
[info] - slow
[info] Run completed in 192 milliseconds.
[info] Total number of tests run: 2
[info] Suites: completed 1, aborted 0
[info] Tests: succeeded 2, failed 0, canceled 0, ignored 0, pending 0
[info] All tests passed.
[success] Total time: 3 s, completed Mar 15, 2014 12:25:06 PM

到目前为止一切顺利。但现在：

> test-only Test -- -l org.scalatest.tagobjects.Slow
[info] Test:
[info] - fast
[info] - slow
[info] Run completed in 108 milliseconds.
[info] Total number of tests run: 2
[info] Suites: completed 1, aborted 0
[info] Tests: succeeded 2, failed 0, canceled 0, ignored 0, pending 0
[info] All tests passed.
[success] Total time: 0 s, completed Mar 15, 2014 12:25:39 PM
> test-only Test -- -n org.scalatest.tagobjects.Slow
[info] Test:
[info] Run completed in 93 milliseconds.
[info] Total number of tests run: 0
[info] Suites: completed 1, aborted 0
[info] Tests: succeeded 0, failed 0, canceled 0, ignored 0, pending 0
[info] No tests were executed.
[success] Total time: 0 s, completed Mar 15, 2014 12:25:42 PM

使用-l排除标记并未排除任何内容，使用-n包含标记时不包含任何内容。

问题不是特定于sbt / ScalaTest集成，因为如果我直接运行跑步者它也会失败：

> test:run-main org.scalatest.tools.Runner -o -R target/scala-2.10/test-classes -l org.scalatest.tagobjects.Slow

我做错了什么？

Answer 1

您需要使用“org.scalatest.tags.Slow”作为标记名称，如the ScalaDoc for Slow中所述。

不幸的是，注释和对象不可能具有相同的完全限定名，因此我们使用注释的完全限定名作为标记名称。

Answer 2

工作示例：

如“标记测试”中的http://doc.scalatest.org/2.1.0/index.html#org.scalatest.FunSuite所述，您必须传递一个扩展org.scalatest.Tag的对象。例如：

import org.scalatest.FlatSpec
import org.scalatest.Tag
import org.scalatest.tags.Slow

object Other extends Tag("com.mycompany.groups.Other")

class Test extends org.scalatest.FunSuite {
  test("fast") {
    assertResult(4)(2 + 2) }

  test("slow", org.scalatest.tagobjects.Slow ) {
    assertResult(40)(20 + 20) }

  test("other", Other){
    assertResult(42)(21 + 21)   }
}

ScalaTest runner + FunSuite +标签：不能让`-n`和`-l`包含/排除标签？
