Unit testing using JUNIT4 Spring-test in Java SSH framework

Due to the fact that the bean is given to spring management under the framework of SSH, it is more difficult to do unit test, and JUNIT4 to introduce annotations easily.

1. Join the dependency Package

Using Spring's test framework requires adding the following dependency packages:

• JUnit 4 (Official download: http://www.junit.org/)
• Spring Test (Test package in spring framework)
• Spring related other dependencies (no more, it's the context package)

2. Create test source catalogs and packages

　　Here, it is recommended to create a source file directory with SRC peers, because the classes within SRC are prepared for future products, and the classes here are for testing purposes only. and the name of the package can be the same as the directory in SRC, so because in the test source directory (source file), so there is no conflict, and the name is identical, more convenient to retrieve.

3. Create a test class

　　Create a test class with the recommended name "tested class name + Test".

　　The test class should inherit with abstractjunit4springcontexttests or abstracttransactionaljunit4springcontexttests

　　For abstractjunit4springcontexttests and Abstracttransactionaljunit4springcontexttests classes, choose from:

If you need to use transaction management in your test class (for example, to roll back the test content after the test results have been rolled out), the Abstracttransactionaljunit4springtests class can be used. The use of transaction management is the same as the normal use of spring transaction management. It is important to note that if you want to use declarative transaction management, that is, using the Abstracttransactionaljunitspringcontexttests class, in the Applicationcontext.xml file Add the TransactionManager bean:

<bean id= "TransactionManager"
    class= "Org.springframework.jdbc.datasource.DataSourceTransactionManager" >
    <property name= "DataSource" ref= "DataSource"/>
</bean>

If no such bean is added, Nosuchbeandefinitionexception will be thrown, indicating no bean named ' TransactionManager ' is definded.
　

4. Configuring the Test class

　　Add the following in front of class to configure the location of the Applicationcontext.xml file.

@RunWith (Springjunit4classrunner.  Class

@ContextConfiguration (locations={"Classpath:/config/applicationcontext-*.xml", "classpath:/config/ Applicationcontext-beans-*.xml "," Classpath:/config/applicationcontext-beans.xml "})

5. Create a test method

　　To create a test method, the recommended name is "test method name + test".

　　Add @Test above the test method

6. Execute via JUnit 4

　　Right-click the method name and select "Run as" → "JUnit Test" to

Package com.zjpost.bank.service;


Import Javax.annotation.Resource;


Import Org.junit.Test;
Import Org.junit.runner.RunWith;
Import org.springframework.test.context.ContextConfiguration;
Import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
Import Org.springframework.test.context.junit4.SpringJUnit4ClassRunner;


@RunWith (Springjunit4classrunner.class)
@ContextConfiguration (locations={"Classpath:/config/applicationcontext-*.xml", "classpath:/config/ Applicationcontext-beans-*.xml "," Classpath:/config/applicationcontext-beans.xml "})
public class Mbankdetailicbcserviceimpltest extends
abstractjunit4springcontexttests {
@Resource
Private Mbankdetailicbcserviceimpl Mbankdetailicbcservice;

@Test
public void Getbankdata () {
Mbankdetailicbcservice.getbankdata ();
}


}

@Resource can specify name or Tpye
