这里我们将看到一个使用POJO类,业务逻辑类和测试类的JUnit测试的完整示例,它将由测试运行器运行.
创建 C:\> JUNIT_WORKSPACE中的EmployeeDetails.java ,这是一个POJO类.
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 类用于 : 去;
获取/设置员工姓名的值.
获取/设置员工月薪的值.
获取/设置员工年龄的值.
在C中创建名为 EmpBusinessLogic.java 的文件:\> JUNIT_WORKSPACE,包含业务逻辑.
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 类用于计算 : 去;
员工的年薪.
员工的评估金额.
在C:\> JUNIT_WORKSPACE中创建一个名为 TestEmployeeDetails.java 的文件,其中包含要测试的测试用例.
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 类用于测试 EmpBusinessLogic 的方法b>上课.它
测试员工的年薪.
测试员工的评估金额.
接下来,在C:\> JUNIT_WORKSPACE中创建一个名为 TestRunner.java 的java类来执行测试用例(s).
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()); }}
使用javac编译测试用例和Test Runner类.
C:\JUNIT_WORKSPACE>javac EmployeeDetails.java EmpBusinessLogic.java TestEmployeeDetails.java TestRunner.java
现在运行Test Runner,它将运行在提供的Test Case类中定义的测试用例.
C:\ JUNIT_WORKSPACE> java TestRunner
验证输出.
