JUnit测试类（netbeans）上没有可运行的方法

Question

请帮助我！

我创建了一个EmployeeTest类来写入Employee类，但在我完成它之前发生此错误。我在这个项目之前写过类似的项目，它没有错误地运行。这是一个非常简单的类，如下所示。

这是错误消息：

initialization ERROR : No runnable methods 
    -No runnable methods 
    -java.lang.Exception 
    -at java.lang.reflect.Constructor.newInstance(Constructor.java:526) 

这是EmployeeTest类：

import org.junit.AfterClass; 
import org.junit.Before; 
import org.junit.BeforeClass; 
import org.junit.Test; 
import static org.junit.Assert.*; 

public class EmployeeTest { 
Employee employee; 
public EmployeeTest() { 
} 

@BeforeClass 
public static void setUpClass() { 
} 

@AfterClass 
public static void tearDownClass() { 
} 

@Before 
public void setUp() { 
    employee = new Employee("Austin", "Powers", 70000.00); 
} 
public void testGetName(){ 
    String expected = "Austin Powers"; 
    String actual = employee.getName(); 
    assertEquals(expected, actual); 


} 
public void testGetSalary(){ 
    double expected = 70000.00; 
    double actual = employee.getSalary(); 
    double marginOfError = 0.0001; 
    assertEquals(expected, actual, marginOfError); 
} 
public void testChangeSalary(){ 

    double percentIncrease = 5.00; 
    employee.changeSalary(percentIncrease); 
    double expected = 73500.00; 
    double actual = employee.getSalary(); 
    double marginOfError = 0.0001; 
    assertEquals(expected, actual, marginOfError); 
    } 
} 

这是未完成的Employee类：

class Employee { 
private String firstName; 
private String lastName; 
private double salary; 

public Employee(String austin, String powers, double d) { 
    firstName = austin; 
    lastName = powers; 

} 


String getName() { 
    return firstName +" "+lastName; 
     } 

double getSalary() { 
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates. 
} 

void changeSalary(double percentIncrease) { 
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates. 
    } 

}

您需要注释添加到您的测试方法如下：

@Test 
public void testGetSalary(){ 

与Junit 3不同，JUnit 4依赖注释而不是方法名来标识测试。
