how to write junit test

In the development of projects, it is unavoidable to use unit testing. Let's start with some basic concepts. 1) @Test @ is the meaning of the annotation, @Test is the basis of the JUnit test, which means that the method under the note is run with JUnit testing. 2) Import p

When we write large programs, we need to write thousands of methods or functions that may be powerful, but we only use a small subset of the functions of the function in our program, and by debugging we can determine that a small subset of the functionality is correct. However, we should also make sure that each function is completely correct, because if we extend the program in the future and use the other

today, when testing Hibernate's additions and deletions, I encountered a problem: there are four test methods in a test class: Add (), search (),Update () and delete (), but after clicking on a class such as the update () method, the other three methods will execute, initially suspecting that hibernateConfiguration problem, but found all over and did not find where there is a problem, finally understand, th

junit Test HighlightsPreface:A program from a well-designed state to start, with the new features continue to join, the program gradually lost its original structure, and eventually become mess. So in the development process, for programmers, testing is very important. Anyway, start JUnit's test.It is convenient to use JUnit for unit testing in Eclipse/myeclipse,

In the "programmers who don't write unit tests are not good programmers" principle, I'm sticking with the unit test, not saying that all Java Web applications are based on spring, but at least more than half are spring-based. After discovering bean management through spring, there are a variety of deficiencies in testingFor example, when many people do unit tests, they also initialize the spring container i

Android SDK 1.5 has been included in JUnit, used once, last night re-use when there is a bit of a problem, or decided to write a more detailed article for everyone and their future use, writing is also very convenient, JUnit under Android is an extension to JUnit under Java, which is basically similar toabout JUnitJUni

Spring-test using JUnit, the test class uses autowired to make an error,Report Create Bean Error ...But the controller inside @autowired can run normally.Ask questions on the Internet and confirm that I must have a problem with the scan package. But the controller inside is clearly can get AH.Wait, I'm building a project using MAVEN, and the project is divided in

IntelliJ idea is most people generally recognized the best use of the IDE, but myeclipse after all the Overlord has done so many years, the Internet can find a comparative system of basic tutorials are myeclipse, so here to write an article IntelliJ Idea for a detailed graphic tutorial on unit testing. IntelliJ idea has integrated the Junit package internally, so you don't need to download it yourself. 1 Wh

JUnit Unit tests:1. What is unit testing: After we have completed a project, we need to make a simple full-aspect test of its code logic, to see if the code logic is correct, for example, we wrote a log of the code, test, we will use the mobile phone number, account to log in to see if it can be boarded, if the wrong password or account to see if All these need t

course, if you need to test both of these two test classes together, it can be implemented by the Testsuite class, which is equivalent to a suite that can add all the test classes and run tests together.The code is as follows:[Java]View Plaincopy Package com.phicomme.test; Import com.phicomme.hu.StudentTest02; Import Junit.framework.Test; Import
