The suite test refers to group a few unit test cases and run it together. The @RunWith and @Suite annotation are used to run the suite test.
Example:
TestSuite.java
import org.junit.runner.RunWith; import org.junit.runners.Suite; /** * This class is used as suite test class. * Both DivisionTestCase1 and DivisionTestCase2 * executes together after TestSuite is executed. * @author javawithease */ @RunWith(Suite.class) @Suite.SuiteClasses({ DivisionTestCase1.class, DivisionTestCase2.class }) public class TestSuite { } |
DivisionTestCase1.java
import com.javawithease.business.*; import static org.junit.Assert.*; import org.junit.Test; /** * This is test case class for division method. * @author javawithease */ public class DivisionTestCase1 { //DivisionTest class objects DivisionTest divisionTest1 = new DivisionTest(10, 2); DivisionTest divisionTest2 = new DivisionTest(10, 0); //Test case for division @Test public void test() { System.out.println("In DivisionTestCase1.test"); assertEquals(5, divisionTest1.division()); } //Test case for expected ArithmeticException, //As in this case ArithmeticException // is the expected exception so JUnit //will pass this unit test. @Test(expected = ArithmeticException.class) public void testException() { System.out.println("In DivisionTestCase1.testException"); assertEquals(5, divisionTest2.division()); } } |
DivisionTestCase2.java
import com.javawithease.business.*; import static org.junit.Assert.*; import org.junit.Test; /** * This is test case class for division method. * @author javawithease */ public class DivisionTestCase2 { //DivisionTest class objects DivisionTest divisionTest = new DivisionTest(10, 5); //Test case for division @Test public void test() { System.out.println("In DivisionTestCase2.test"); assertEquals(2, divisionTest.division()); } } |
DivisionTest.java
/** * This is simple java class containing division method. * @author javawithease */ public class DivisionTest { //data members int num1, num2; //parameterised constructor public DivisionTest(int num1, int num2){ this.num1 = num1; this.num2 = num2; } //division method public int division() throws ArithmeticException{ return num1/num2; } } |
Output:
In DivisionTestCase1.test In DivisionTestCase1.testException In DivisionTestCase2.test |
