junit测试

1.项目名.iml文件

<orderEntry type="library" name="KotlinJavaRuntime" level="project" />
<orderEntry type="library" name="junit:junit:4.13" level="project" />

2.测试类

class StudentDao {
    fun add() {
        println("添加学生")
    }

    fun update() {
        println("更新学生")
    }

}

class StudentDaoTest {
    companion object {
        @BeforeClass
        @JvmStatic
        fun setUpBeforeClass() {
            println("测试类执行之前。。。。。。。。。")
        }

        @AfterClass
        @JvmStatic
        fun tearDownAfterClass() {
            println("测试类执行之后。。。。。。。。。")
        }
    }

    @Before
    fun setUp() {
        println("方法之前执行........")
    }

    @After
    fun tearDown() {
        println("方法之后执行........")
    }

    @Test
    fun test() {
        println("测试方法")
    }

    @Test
    fun test2() {
        println("测试方法2")
    }

    @Test
    fun testAdd() {
        val studentDao = StudentDao()
        studentDao.add()
    }

    @Test
    fun testUpdate() {
        val studentDao = StudentDao()
        studentDao.update()
    }

}
