EE308 LAB 11 Software Testing

Learn related knowledge about Junit Test for Java and Unittest for python. You can finish the following assignment or test Your Project.

1. Here are Junit Test task and Unittest task for choose. If you are good at Java , we suggest you choose the first one, if you are good at Python, then, the latter one.
2. Follow the requests and tips, complete the test task .

1. You should be familiar with Junit Test or Unittest and the usage of these tools.Such as ‘assert, suite, timeout’, check problems for detail.
2. Fix the missing codes according to requirement for every problem.

1. Junit assert

AssertionsTest.java

import static org.junit.Assert.*;
import org.junit.Test;
 
public class AssertionsTest {
    String obj1 = "junit";
    String obj2 = "junit";
    String obj3 = "test";
    String obj4 = "test";
    String obj5 = null;
    int var1 = 1;
    int var2 = 2;
    int[] arithmetic1 = { 1, 2, 3 };
    int[] arithmetic2 = { 1, 2, 3 };
 
    @Test
    public void test() {
        // add assert test code between Begin and End, no other change allowed 
        
		//assertTrue(var1 < var2); for example
		assertEquals(obj1, obj2);
		assertTrue(var1 < var2);
		assertFalse(var1 > var2);
		assertNotNull(obj3);
		assertNull(obj5);
		assertArrayEquals(arithmetic1, arithmetic2);
        
    }
 
}

2. Junit time test

TestTimeOut.java

import org.junit.Test;

public class TestTimeOut {

    // Fix timeout assert in Test function below. Test fail if running 1000ms longer
    
	
    @Test(timeout=1000)
    public void test() {
        while(true){}
    }
    
}

3. Junit parameterized test

ParameterTest.java

import static org.junit.Assert.assertEquals; // static import

import java.util.Arrays;
import java.util.Collection;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;
import step1.Calculator;



@RunWith(Parameterized.class)
public class ParameterTest {

    private int input11;
    private int input22;
    private int expected;

    public ParameterTest(int input11, int input22, int expected){
        this.input11 = input11;
        this.input22 = input22;
        this.expected = expected;
    }

    @Parameters
    public static Collection prepareData(){

        

        
    	Object o[][] = {{1,2,3},{3,2,1},{5,3,2},{2,3,1}};
    	return Arrays.asList(o);
		

    }

    @Test
    public void testSub(){
        Calculator cal = new Calculator();
        assertEquals(cal.sub(input11, input22), expected);
    }
}

4. Junit Exception Test

JunitException.java

import static org.junit.Assert.*;

import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.ExpectedException;
import step2.Person;

 
public class JunitException {

    

    
	@Test(expected=IllegalArgumentException.class)
  	

    public void checkage() {
    Person person = new Person();
    person.setAge(-1);
    }
}

5. Junit Suite Test

ParameterTest.java

import static org.junit.Assert.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import step3.Calculate;
import step3.CalculateTest;
import step3.Car;
import step3.CarTest;
 


//**************************************************************
@RunWith(Suite.class)
@Suite.SuiteClasses({ CalculateTest.class, CarTest.class})
public class SuiteTest {}
