how to write junit test

The junit4.x version needs to introduce the following jar packages:Hamcrest-core-1.3.jarJunit-4.12-beta-3.jarCreate a new Calculator class, as follows: Packagecom.pt; Public classCalculate {/*** addition *@paramD1 *@paramD2 *@return */ Public Static DoubleAddDoubleD1,DoubleD2) { returnD1 +D2; } /*** Subtraction *@paramD1 *@paramD2 *@return */ Public Static DoubleDiffDoubleD1,DoubleD2) { returnD1-D2; } /*** Multiplication *@paramD1 *@paramD2 *@return

JUnit unit test transactions are automatically rolled back. Implemented by @rollback (true) annotation, the default is true, the transaction is rolled back, and can not be written. False, the transaction is not rolled back and the data is written to the database. Instance: Package com.xiaolyuh.service; Import Java.util.Date; Import Org.junit.Assert; Import Org.junit.Test; Import Org.junit.runner.RunWith;

Refer to http://www.blogjava.net/sitinspring/archive/2007/06/20/125224.html and run the JUnit classes with Maven. But the run MVN test, but reported that no test class found, namely: There are no tests to run. When you're depressed, check out the MAVEN reference and find out that it was the default behavior of the Surefire plug-in. MAVEN performs tests using the

Remember the previous contact with JUnit, the test of the public method is very fluent, and the private method is also called in these public methods, will test coverage.

Transferred from: Http://www.coderli.com/junit-spring-test-applicationcontext The spring framework is used in JUnit unit test cases, directly as follows. @RunWith (Springjunit4classrunner.

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.
