First of all ,suite , Chinese is A set of , A group of It means .

that ,TestSuite, seeing the name of a thing one thinks of its function , It's used to run a set of tests .

How to use it ?

Suppose there is a test class like this  StudentDAOTest , The code is as follows :

 package org.young.junit.testsuite;
import junit.framework.TestCase;
import org.young.junit.testsuite.dao.StudentDAO;
import org.young.junit.testsuite.dao.StudentDAOImpl;
import org.young.junit.testsuite.entity.Student; public class StudentDAOTest extends TestCase { private StudentDAO dao; /**
* establish DAO example
public void setUp() {
dao = new StudentDAOImpl();
} public void testAdd() {
Student stu = new Student(); dao.add(stu);
} public void testDelete() { dao.delete("id");
} public void testUpdate() {
Student stu = new Student(); dao.update(stu);
} public void testLoadWithId() { Student stu = dao.load("xyz"); assertNotNull(stu);
} public void testLoadWithNullOrEmptyStr() { Student stu = dao.load("");
assertNull(stu); stu = dao.load(null);
} }

If you want to execute several methods at a time , Instead of changing all the methods ?

TestSuite It's time to play. .

For comparison , Another test class  CourseDAOTest , The code is as follows :

 package org.young.junit.testsuite;
import org.junit.Before;
import org.junit.Test;
import org.young.junit.testsuite.dao.CourseDAO;
import org.young.junit.testsuite.dao.CourseDAOImpl;
import org.young.junit.testsuite.entity.Course; import junit.framework.TestCase;
import junit.framework.TestSuite; /**
* Suite The first way to achieve this is
* public static Test suite(){} The way
* @author by Young.ZHU
* on 2013-9-30
* Package&FileName: org.young.junit.testsuite.CourseDAOTest
public class CourseDAOTest extends TestCase { private CourseDAO dao; public CourseDAOTest() {
} public CourseDAOTest(String name) {
} @Override
protected void setUp() throws Exception {
super.setUp(); dao = new CourseDAOImpl();
} /**
* Be careful : Inherit TestCase after ,JUnit 4 Inside @Before 、@Test It's no use waiting for annotations
* @Before The function of can be determined by the method setUp() Realization
public void init() {
dao = new CourseDAOImpl();
} /**
* Execute some methods of this test class
* The method head must be like this public static junit.framework.Test suite()
* namely , static state (static) Of
* @return
public static junit.framework.Test suite() {
TestSuite suite = new TestSuite(); /*
* The string parameter is the method of the test class that you want to execute
suite.addTest(new CourseDAOTest("testLoad"));
suite.addTest(new CourseDAOTest("testAdd")); return suite;
} @Test
public void testAdd() {
Course course = new Course(); dao.add(course);
} @Test
public void testDelete() {
fail("Not yet implemented");
} @Test
public void testUpdate() {
fail("Not yet implemented");
} @Test
public void testLoad() {
Course course = dao.load("course_id"); assertNotNull(course);
} }

Run it first , Look at the effect :

Although this test class has been added (add)、 Delete (delete)、 Change (update)、 check (load), But there are only two methods that actually work —— testLoad and testAdd .

The secret is code number 60 Yes  suite() Method , This method determines which methods the test class executes .

There are two points to explain :

1、 About the way  suite() It's the first way

As the note says , The method head of this method is fixed

 public static junit.framework.Test suite() {
// your code ...

2、 Test class construction method

Test class  CourseDAOTest   pass the civil examinations 30 Constructor with arguments on line , stay 66 Row sum 67 Yes, it does .

The parameter of the constructor is the name of the test method to be executed .

Last , Put the two together , Test class  AllTest , The code is as follows :

 package org.young.junit.testsuite;
import junit.framework.TestSuite;
public class AllTest {
public static junit.framework.Test suite() {
TestSuite suite = new TestSuite("All Test"); /*
* StudentDAOTest All test methods for class
suite.addTest(new TestSuite(StudentDAOTest.class));
* CourseDAOTest Partial methods of the class
suite.addTest(CourseDAOTest.suite()); return suite;
} }

After operation , The effect is as follows :
