How to run a single test in scalatest from maven
提问by javadba
I have not found any documentation on how to do this. For JUnit the equivalent would be:
我还没有找到任何有关如何执行此操作的文档。对于 JUnit，等效项是：
mvn -Dtest=org.apache.spark.streaming.InputStreamSuite test

tl;drmvn test -Dsuites="some.package.SpecsClass"
tl;博士mvn test -Dsuites="some.package.SpecsClass"
I found an answer from here and it works:(https://groups.google.com/forum/#!topic/scalatest-users/Rr0gy61dg-0)
我从这里找到了一个答案并且它有效:( https://groups.google.com/forum/#!topic/scalatest-users/Rr0gy61dg-0)
run test 'a pending test' in HelloSuite, and all tests in HelloWordSpec:
在 中运行 test 'a pending test' HelloSuite，并在 中运行所有测试HelloWordSpec：
mvn test -Dsuites='org.example.
HelloSuite @a pending test, org.example.HelloWordSpec'
run all tests in
HelloSuitecontaining'hello':mvn test-Dsuites='org.example.HelloSuitehello'
运行
HelloSuite包含的所有测试'hello'：mvn test-Dsuites='org.example.HelloSuitehello'

Found the answer: it is
找到答案：是
-DwildcardSuites
So here is the example command line:
所以这是示例命令行：
mvn -pl streaming -DwildcardSuites=org.apache.spark.streaming.InputStreamSuite test
UpdateNewer versions of scalatestuse
更新较新的scalatest使用版本
-Dsuites
So the syntax would be:
所以语法是：
mvn -pl streaming -Dsuites=org.apache.spark.streaming.InputStreamSuite test

Note that if you have some Java tests in the same module, as much of spark does, you need to turn them off -which you can do by telling surefire to run a test that isn't there
请注意，如果您在同一模块中有一些 Java 测试，就像 spark 所做的那样，您需要将它们关闭 - 您可以通过告诉 surefire 运行不存在的测试来实现
Here is the test that I've just been running
这是我刚刚运行的测试
mvn test -Dtest=moo -DwildcardSuites=org.apache.spark.deploy.yarn.ClientSuite
That skips the java test and only runs the scala one.
这会跳过 java 测试，只运行 Scala 测试。
One thing which scalatest doesn't seem to do is let you run a single test within a suite, the way maven surefire does. That's not ideal if you have one failing test in a big suite.
scalatest 似乎没有做的一件事是让您在套件中运行单个测试，就像 maven surefire 那样。如果您在大型套件中进行了一项失败的测试，那这并不理想。
[Correction 2016-08-22: looks like you can ask for a specific suite by name; look at the other answers below. Happy to be wrong].
[更正 2016-08-22：看起来您可以按名称要求特定套房；看看下面的其他答案。乐于犯错]。
