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。
| 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
在 C:\ > JUNIT_WORKSPACE 路径下创建一个名为 EmpBusinessLogic.java 的 business logic 类
| 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; |
| } |
| } |
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
| 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
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
| 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()); |
| } |
| } |
| C:\JUNIT_WORKSPACE>javac EmployeeDetails.java |
| EmpBusinessLogic.java TestEmployeeDetails.java TestRunner.java |
| C:\JUNIT_WORKSPACE>java TestRunner |
| true |
