[This article is from the Sky Cloud-owned blog Park]Brief descriptionUsing JUnit combined with Mockito, coupled with some of the Spingframework's own methods, can be combined to test the controller layer in spring MVC.Before we design the test case, we have to take the logic of the controller's code in-depth and go through the drill-by-layer. The purpose of the w

using ant to integrate JUnit for Automatic Testing and generate test reports can greatly improve the test efficiency. The advantage is the batch processing function of test cases. Not long ago, I saw a lot of articles about JUnit testing on the Internet: . I'm glad ant has

Using the spring framework to make it easy to write code with separate tests for some code snippet code without having to run the entire environment for testing, the JUnit test is introduced to facilitate the testing of the local code block.1, first guide package, such as MAVEN project: where JUnit needs at least in the 4.12 version, or will be

Since only one junit test has been written, and the test project logic is complex, the following are just a few of the solutions to the problems encountered in the test.Web server: LinuxClient: Linux/windows (as long as you can execute Java program, test Java-jar Test_client.jar)Problem1, because the

The course design requires the JUnit test, which I tested on the already well-done SSH project, and the test class code is as followsPackage Com.zhang.web.services;importStaticorg.junit.assert.*; import org.junit.after;import org.junit.before;import org.junit.test;import javax.annotation.Resource; Import Org.junit.runner.RunWith; Import Org.springframework.test.

Accuracy test (result accuracy testing)For example, Assert.assertequals (expected, actual).If the result does not meet the expectations, it produces failure. Indicates a problem with the program logic.Failure test (throwing exception tests)The expected property is used to indicate the type of exception expected to be thrown. For example, @Test (expected = illegal

The Hibernate entity classes and their mapping files are also placed in the project, and because there are multiple projects using the same database, Hibernate entity classes and mapping files are duplicated, which is inconvenient for maintenance and upgrades. Therefore, it is extracted, made into a jar package, and then introduced back to the project. In practice, there is a strange problem: The project runs fine, but the JUnit unit
