认识Junit基本注解@Before、@After、@Test、@BeforeClass、@AfterClass(转)
一、unit中集中基本注解,是必须掌握的。
- @BeforeClass – 表示在类中的任意public static void方法执行之前执行
- @AfterClass – 表示在类中的任意public static void方法执行之后执行
- @Before – 表示在任意使用@Test注解标注的public void方法执行之前执行
- @After – 表示在任意使用@Test注解标注的public void方法执行之后执行
- @Test – 使用该注解标注的public void方法会表示为一个测试方法
二、使用示例
【code】
package org.byron4j.spring_mvc_log4j; import org.junit.After; import org.junit.AfterClass; import org.junit.Before; import org.junit.BeforeClass; import org.junit.Test; public class BasicAnnotationTest { // Run once, e.g. Database connection, connection pool @BeforeClass public static void runOnceBeforeClass() { System.out.println("@BeforeClass - runOnceBeforeClass"); } // Run once, e.g close connection, cleanup @AfterClass public static void runOnceAfterClass() { System.out.println("@AfterClass - runOnceAfterClass"); } // Should rename to @BeforeTestMethod // e.g. Creating an similar object and share for all @Test @Before public void runBeforeTestMethod() { System.out.println("@Before - runBeforeTestMethod"); } // Should rename to @AfterTestMethod @After public void runAfterTestMethod() { System.out.println("@After - runAfterTestMethod"); } @Test public void test_method_1() { System.out.println("@Test - test_method_1"); } @Test public void test_method_2() { System.out.println("@Test - test_method_2"); } }
【输出】
@BeforeClass - runOnceBeforeClass @Before - runBeforeTestMethod @Test - test_method_1 @After - runAfterTestMethod @Before - runBeforeTestMethod @Test - test_method_2 @After - runAfterTestMethod @AfterClass - runOnceAfterClass
