配置

修改pom.xml，添加以下内容

<!--依赖-->
<dependency><groupId>org.scalatest</groupId><artifactId>scalatest_2.11</artifactId><version>3.0.0</version><scope>test</scope>
</dependency><!--插件-->
<plugin><groupId>org.scalatest</groupId><artifactId>scalatest-maven-plugin</artifactId><version>1.0</version><configuration><reportsDirectory>${project.build.directory}/surefire-reports</reportsDirectory><junitxml>.</junitxml><filereports>WDF TestSuite.txt</filereports></configuration><executions><execution><id>test</id><goals><goal>test</goal></goals></execution></executions>
</plugin><!--测试代码和文件-->
<testSourceDirectory>${basedir}/src/test/scala</testSourceDirectory>

一个简单的例子

import org.scalatest.FunSuite
class SetFuncSuite extends FunSuite {//差集test("Test difference") {val a = Set("a", "b", "a", "c")val b = Set("b", "d")assert(a -- b === Set("a", "c"))}//交集test("Test intersection") {val a = Set("a", "b", "a", "c")val b = Set("b", "d")assert(a.intersect(b) === Set("b"))}//并集test("Test union") {val a = Set("a", "b", "a", "c")val b = Set("b", "d")assert(a ++ b === Set("a", "b", "c", "d"))}
}

在IDEA里直接运行

程序打包时会自动进行测试

mvn clean package

如果测试通过，

如果测试不通过，则会打包失败，比如

  test("Test difference") {val a = Set("a", "b", "a", "c")val b = Set("b", "d")//应该等于Set("a","b")assert(a -- b === Set("b", "c"))}
