1. Junit assert

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() {
		assertEquals(obj1, obj2);
		assertEquals(obj3, obj4);
		assertNull(obj5);
		assertTrue(var1 < var2);
		assertArrayEquals(arithmetic1, arithmetic2);
    }
}

  2.Junit time test

import org.junit.Test;

public class TestTimeOut {

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

3.Junit parameterized test

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;
/**
 * JUnit4 parameterized test
 */
@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(){
        /**
         *the type of the two-dimension array must be Object.
         *data in the two-dimension array is ready of test sub() in Calculator
         * every element in the two-dimension array should corresponds to position of parameters in construct method ParameterTest
         *let the third element equals the first subtract the second element according to parameters’ postion
         *fix missing codes under ‘Begin’ and above ‘End’，pass 4 groups of parameters to test sub method in Calculator is right or not 
         *tip：only two lines of codes 
         */
        /*********************************Begin********************************************/
    	Object zx [][]= {{1,2,3},{5,6,-1},{9,5,4},{4,3,0}};
    	return Arrays.asList(zx);
        /**********************************End********************************************/
    }
    @Test
    public void testSub(){
        Calculator cal = new Calculator();
        assertEquals(cal.sub(input11, input22), expected);
    }
}

4.Junit Exception Test

import static org.junit.Assert.*;

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



public class JunitException {

    /**
*add a line of annotation in Begin/End，check the age of Person Object is legal or not.     *throw IllegalArgumentException exception
    */
    /***********************************Begin***********************************/
    @Test(expected = IllegalArgumentException.class)
  /************************************End************************************/
    public void checkage() {
    Person person = new Person();
    person.setAge(-1);
    }
}

5.Junit Suite Test

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;

/*
add two lines of annotations. Implement Suite Test of CalculateTest and CarTest
Suite Test codes must next to Class SuiteTest, no shift allowed!
*/
//**************************************************************
@RunWith(Suite.class)
@Suite.SuiteClasses({CalculateTest.class,CarTest.class})
public class SuiteTest {
	
}
