scalaTest的使用

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"))
  }
