· 编写业务逻辑
· 针对业务逻辑中涉及的方法编写测试类，在代码中插入TestNG的注解
· 直接执行测试类或者添加一个testng.xml文件
· 运行 TestNG.
下面我们介绍一个完整的例子来测试一个逻辑类；
1.创建一个pojo类EmployeeDetail.java
public class EmployeeDetail { 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; } } |
EmployeeDetail用来：
· get/set 员工的名字的值
· get/set 员工月薪的值
· get/set员工年龄的值
2.创建一个EmployeeLogic.java
public class EmployeeLogic { // Calculate the yearly salary of employee public double calculateYearlySalary(EmployeeDetail employeeDetails){ double yearlySalary=0; yearlySalary = employeeDetails.getMonthlySalary() * 12; return yearlySalary; } } |
EmployeeLogic.java用来：
计算员工年工资
3.创建一个测试类，为NewTest，包含测试用例，用来进行测试；
import org.testng.Assert; import org.testng.annotations.Test; import org.testng.annotations.BeforeMethod; import org.testng.annotations.AfterMethod; import org.testng.annotations.DataProvider; import org.testng.annotations.BeforeClass; import org.testng.annotations.AfterClass; import org.testng.annotations.BeforeTest; import org.testng.annotations.AfterTest; import org.testng.annotations.BeforeSuite; import org.testng.annotations.AfterSuite; import com.thunisoft.Employee.EmployeeDetail; public class NewTest { EmployeeLogic empBusinessLogic = new EmployeeLogic(); EmployeeDetail employee = new EmployeeDetail(); // test to check yearly salary @Test public void testCalculateYearlySalary() { employee.setName("Rajeev"); employee.setAge(25); employee.setMonthlySalary(8000); double salary = empBusinessLogic .calculateYearlySalary(employee); Assert.assertEquals(96000, salary, 0.0, "8000"); } } |
NewTest.java类作用：测试员工年薪
4.测试执行：选中这个类-》右键-》run as 选择TestNG Test
5.查看执行结果
控制台会输出如下：
可以看到，运行了一个test，成功输出
TestNG输出控制台结果如下：
我们可以看到运行了一testCalculateYearlySalary测试方法，并且测试通过。
如果我们将测试代码中的Assert.assertEquals(96000, salary, 0.0, "8000");改为
Assert.assertEquals(86000, salary, 0.0, "8000");，则运行结果如下：
