Summary of unit tests using spring with JUnit

Recent company projects and their own projects have used spring integrated junit for unit testing, summarizing several basic uses:

1. Test the bean injected directly in spring (in DAO, for example):

Adding @runwith annotations on a test class specifies the test runner using Springjunit, @ContextConfiguration note Specifies the location of the spring configuration file for the test

Then we can inject the beans we need to test, and JUnit will parse the spring configuration file before running the test and initialize the bean configured in spring

@RunWith (Springjunit4classrunner.class) @ContextConfiguration (locations={"Classpath*:spring-config-test.xml "}) Public classTestprojectdao { @Autowired projectdao Projectdao;     
@Test     Public voidTestcreateprojectcode () {LongApplytime =System.currenttimemillis (); Timestamp TS=NewTimestamp (applytime); Map CodeMap= Projectdao.generatecode ("5", "8", TS, "in hospital")); String Projectcode= (String) codemap.get ("_project_code"); Timestamp Apply_time= (Timestamp) codemap.get ("_apply_time");        System.out.print (Projectcode);        System.out.print (Apply_time.tostring ()); Assert.asserttrue (Projectcode.length ()==12); }    

2. Test the SPRINGMVC:

ORG.SPRINGFRAMEWORK.TEST.WEB.SERVLET.MOCKMVC class spring3.2 followed by support for SPRINGMVC unit tests

Examples are as follows:

Get (' person '));            System.out.println (Person.getid ());            System.out.println (Person.getname ());            System.out.println (Person.getage ());            System.out.println (Person.getaddress ()); Assert.assertequals (23, Person.getage ()); } Catch(Exception e) {e.printstacktrace (); //To change body of catch statement use File | Settings | File Templates.        }    }}

3. Test the interface provided by the Resteasy (used when using the rest type interface provided by Resteasy)

Resteasy provides the Org.jboss.resteasy.core.Dispatcher class to simulate HTTP requests and return data

This way, you do not have to start the container when you test the interface.

The code is as follows
