I.Junit Assert

package test;
 
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 };

    @Test
    public void test() {

Caculator:

package step1;

*/  
public class Calculator {  
    public int sub(int a, int b) {  
       return a - b;

IV.Junit Exception Test：

package 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);
    }
}

Person:

package test;
 
//Person.java
public class Person {
      private String name;
      private int age;
      public String getName() {
      return name;
      }
      public void setName(String name) {
      this.name = name;
      }
      public int getAge() {
      return age;
      }
      public void setAge(int age) {
      if (age < 0 ) {
      throw new IllegalArgumentException("age is invalid");
      }
  this.age = age;
  }
}

V.Junit Suite Test

package 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;
