在这里,我们将看到一个使用POJO类,业务逻辑类和一个测试类进行JUnit测试的完整示例,该类将由测试运行程序运行。
在C:\> JUNIT_WORKSPACE中创建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-
在C:\> JUNIT_WORKSPACE中创建一个名为EmpBusinessLogic.java的文件,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-
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类的方法。它
接下来,在C:\> JUNIT_WORKSPACE中创建一个名为TestRunner.java的Java类,以执行测试用例。
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Test Case类中定义的测试用例。
C:\JUNIT_WORKSPACE>java TestRunner
验证输出。
true
