編寫TestNG用例測試基本上包括以下步驟:
-
編寫業務邏輯
-
針對業務邏輯中涉及的方法編寫測試類,在代碼中插入TestNG的注解
- 直接執行測試類或者添加一個testng.xml文件
-
運行 TestNG.
下面我們介紹一個完整的例子來測試一個邏輯類;
1.創建一個pojo類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用來:
-
get/set 員工的名字的值
-
get/set 員工月薪的值
-
get/set員工年齡的值
2.創建一個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用來:
計算員工年工資
3.創建一個測試類,為NewTest,包含測試用例,用來進行測試;
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類作用:測試員工年薪
4.測試執行:選中這個類-》右鍵-》run as 選擇TestNG Test
5.查看執行結果
控制台會輸出如下:
可以看到,運行了一個test,成功輸出
TestNG輸出控制台結果如下:
我們可以看到運行了一testCalculateYearlySalary測試方法,並且測試通過。
如果我們將測試代碼中的Assert.assertEquals(96000, salary, 0.0, "8000");改為
Assert.assertEquals(86000, salary, 0.0, "8000");,則運行結果如下:
