Spring and junit Testing

Spring and junit Testing

1. We know that both J2SE and android have junit tests. Using junit can help you easily test the code. In my previous blog, I also wrote some junit test examples for J2SE. Today I will give a little talk about junit in Spring.

Jar packages required for this Spring test:

Spring-test-3.2.0.RELEASE.jar

2. Relationship between Spring and Junit

The left side uses the traditional method, that is, the general J2SE method to test the code, which may cause some problems: <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> Vc3ryb25np1_vcd4kpha + release/release + release/rsbPBy6GjPC9zdHJvbmc + release + 7XEx + m/release + 7PwsPmPC9zdHJvbmc + PC9wPgo8cD48c3Ry B25nPjxicj4KPC9zdHJvbmc + PC9wPgo8cD48c3Ryb25nPjMuvPK1pbXEsLjA/aO6PC9zdHJvbmc + volume "brush: java;"> package cn. wwh. www. spring. bbb. test;/*** function of the class: *** @ author yiye Binzhou * @ version 1.0 * @ Creation Time: 03:22:26 */public class HelloWorld {public void show () {System. out. println ("Hello World! This is my first Spring! ");}}

Test Case:

Package cn. wwh. www. spring. bbb. test; import org. junit. test; import org. junit. runner. runWith; import org. springframework. beans. factory. beanFactory; import org. springframework. beans. factory. annotation. autowired; import org. springframework. test. context. contextConfiguration; import org. springframework. test. context. junit4.SpringJUnit4ClassRunner;/*** function: test the function of writing a test framework in Spring. *** @ author: @ version 1.0 * @ Creation Time: 10:19:41 * // indicates to start the Spring container and run junit in the Spring container @ RunWith (SpringJUnit4ClassRunner. class) @ ContextConfigurationpublic class SpringtestTest {// automatically assemble Spring container @ Autowiredprivate BeanFactory factory; @ Testpublic void testBeanFactory () throws Exception {HelloWorld world = factory. getBean ("helloWorld", HelloWorld. class); world. show ();}}

SpringtestTest-context.xml configuration file:

Note:

(1). @ RunWith (SpringJUnit4ClassRunner. class)

@ ContextConfiguration

@ Autowired

@ Test

These are test labels.

(2). @ ContextConfiguration find the configuration file, which is found from the current path by default.

If you set the file name = Current Test class name-context. xml, you can find in the current path. You can omit the above SpringtestTest-context.xml, the test class is: SpringtestTest. java

If it is not written in accordance with the conventions, the test should be written in the format of the loading path:

@ ContextConfiguration ("classpath: cn/wwh/www/spring/bbb/test/SpringtestTest-context.xml ")
