Question

我有一个Maven程序，可以正常编译。我有这个scala类./src/test/java/ResearchTest.scala

import org.junit.Test

class ResearchTest
{



 @Test
  def justAnExample(): Unit = {
    System.out.println("This test method should be running SCALA")
  }
}

当我运行mvn clean test时，它不运行任何测试，这是输出：

我也有这个java类。/src/test/java/Tests.java：

import org.junit.Test;

public class Tests {
    @Test
   public void justAnExample() {
        System.out.println("This test method should be run JAVA");
    }
}

现在我运行mvn clean测试时，它将运行此测试。

我想在scala中运行测试，应该更改什么？

这也是我的pom.xml文件

Answer 1

运行Maven测试时。您实际上正在使用surefire插件。默认情况下，Surefire插件将自动包含具有以下通配符模式的所有测试类：

“ ** / Test * .java”-包括其所有子目录以及以“ Test”开头的所有Java文件名。
“ ** / * Test.java”-包括其所有子目录以及所有以“ Test”结尾的Java文件名。
“ ** / * Tests.java”-包括其所有子目录以及以“ Tests”结尾的所有Java文件名
“ ** / * TestCase.java”-包括其所有子目录以及所有以“ TestCase”结尾的Java文件名。

我建议您将build.sbt文件添加到项目中，并使用sbt处理scala类。但是，如果需要使用Maven进行此操作，则需要将scalatest-maven-plugin添加到pom中，将scala测试类移至src / test / scala。然后您应该可以使用Maven进行测试。

junit在scala类中找不到测试，但在java类中找到测试（Maven项目）
