Spring JUnit Test

Use spring's mock classes for unit testing:

The spring Framework provides a large number of test mock classes, including mock classes related to Jndi,porlet,web applications. In particular, mock classes related to Web applications can greatly improve the convenience of Web Component testing.

Open the Mock folder (path ... mock\org\springframework\mock\web) of spring's download package, and you will find that there are several files:

Mockhttpservletrequest: is a mock implementation of the HttpServletRequest interface, used to simulate the HTTP request of the client, a very common class.

Mockhttpservletresponse: A mock implementation of the HttpServletResponse interface to simulate the server's response to the client.

Mockhttpsession: A mock implementation of the HttpSession interface.

Delegatingservletinputstream: A mock implementation of the ServletInputStream interface.

Delegatingservletoutputstream:servletoutputstream's mock implementation. You can use this class to intercept and analyze the contents of the stream of the server's output.

Others, such as Mockfilterconfig,mockpagecontext (which can test precompiled JSP), Mockrequestdispatcher,mockservletconfig see the name and know it's probably a mock or something.

Give an example:

Mockhttpservletrequest request = new Mockhttpservletrequest

("POST", "/index.do");　　 

Request.addparameter ("username", "name"); 

request.addparameter ("Password", "word");

Use spring for integration testing:

1, Abstractspringcontexttests class [1], this class all methods are protected, usually do not use this class, and use its subclasses.

2, Abstractdependencyinjectionspringcontexttests class [2]: Inherit from class [1]: name N long. If you only use the Spring Dependency Injection feature, you can have the test case inherit the class.

3, Abstracttransactionalspringcontexttests class [3]: Inherits from class [2], the test cases that inherit the class are performed in spring-managed transactions, and the records on the database do not have any effect after the test is finished. After you have done some work on the database, it will automatically rollback the database, which will ensure that your test has no impact on the environment
