简述
在这里,我们将看到一个完整的 JUnit 测试示例,使用 POJO 类、业务逻辑类和测试类,该类将由测试运行器运行。
创建 EmployeeDetails.java 在 C:\>JUNIT_WORKSPACE 中,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 -
- 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。
创建一个名为 EmpBusinessLogic.java 在 C:\>JUNIT_WORKSPACE 中,其中包含业务逻辑。
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 -
创建一个名为 TestEmployeeDetails.java 在 C:\>JUNIT_WORKSPACE 中,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 类用于测试方法 EmpBusinessLogic班级。它
接下来,创建一个名为的 java 类 TestRunner.java 在 C:\>JUNIT_WORKSPACE 中执行测试用例。
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,它将运行在提供的测试用例类中定义的测试用例。
C:\JUNIT_WORKSPACE>java TestRunner
验证输出。
