junit 编写测试——迹忆客-ag捕鱼王app官网

在这里你将会看到一个应用 pojo 类，business logic 类和在 test runner 中运行的 test 类的 junit 测试的例子。

在 c:\ > junit_workspace 路径下创建一个名为 employeedetails.java 的 pojo 类。

employeedetails.java

public class employeedetails {
   private string name;
   private double monthlysalary;
   private int age;
   /**
   * @return the name
   */
   public string getname() {
      return name;
   }
   /**
   * @param name the name to set
   */
   public void setname(string name) {
      this.name = name;
   }
   /**
   * @return the monthlysalary
   */
   public double getmonthlysalary() {
      return monthlysalary;
   }
   /**
   * @param monthlysalary the monthlysalary to set
   */
   public void setmonthlysalary(double monthlysalary) {
      this.monthlysalary = monthlysalary;
   }
   /**
   * @return the age
   */
   public int getage() {
      return age;
   }
   /**
   * @param age the age to set
   */
   public void setage(int age) {
   this.age = age;
   }
}

employeedetails 类被用于

• 取得或者设置雇员的姓名的值
• 取得或者设置雇员的每月薪水的值
• 取得或者设置雇员的年龄的值

在 c:\ > junit_workspace 路径下创建一个名为 empbusinesslogic.java 的 business logic 类

empbusinesslogic.java

public class empbusinesslogic {
   // calculate the yearly salary of employee
   public double calculateyearlysalary(employeedetails employeedetails){
      double yearlysalary=0;
      yearlysalary = employeedetails.getmonthlysalary() * 12;
      return yearlysalary;
   }
   // calculate the appraisal amount of employee
   public double calculateappraisal(employeedetails employeedetails){
      double appraisal=0;
      if(employeedetails.getmonthlysalary() < 10000){
         appraisal = 500;
      }else{
         appraisal = 1000;
      }
      return appraisal;
   }
}

empbusinesslogic 类被用来计算

• 雇员每年的薪水
• 雇员的评估金额

在 c:\ > junit_workspace 路径下创建一个名为 testemployeedetails.java 的准备被测试的测试案例类

testemployeedetails.java

import org.junit.test;
import static org.junit.assert.assertequals;
public class testemployeedetails {
   empbusinesslogic empbusinesslogic =new empbusinesslogic();
   employeedetails employee = new employeedetails();
   //test to check appraisal
   @test
   public void testcalculateappriasal() {
      employee.setname("rajeev");
      employee.setage(25);
      employee.setmonthlysalary(8000);
      double appraisal= empbusinesslogic.calculateappraisal(employee);
      assertequals(500, appraisal, 0.0);
   }
   // test to check yearly salary
   @test
   public void testcalculateyearlysalary() {
      employee.setname("rajeev");
      employee.setage(25);
      employee.setmonthlysalary(8000);
      double salary= empbusinesslogic.calculateyearlysalary(employee);
      assertequals(96000, salary, 0.0);
   }
}

testemployeedetails 是用来测试 empbusinesslogic 类的方法的，它

• 测试雇员的每年的薪水
• 测试雇员的评估金额

现在让我们在 c:\ > junit_workspace 路径下创建一个名为 testrunner.java 的类来执行测试案例类

testrunner.java

import org.junit.runner.junitcore;
import org.junit.runner.result;
import org.junit.runner.notification.failure;
public class testrunner {
   public static void main(string[] args) {
      result result = junitcore.runclasses(testemployeedetails.class);
      for (failure failure : result.getfailures()) {
         system.out.println(failure.tostring());
      }
      system.out.println(result.wassuccessful());
   }
} 

用javac编译 test case 和 test runner 类

c:\junit_workspace>javac employeedetails.java 
empbusinesslogic.java testemployeedetails.java testrunner.java

现在运行将会运行 test case 类中定义和提供的测试案例的 test runner

c:\junit_workspace>java testrunner

检查运行结果
