我试图用我的3个测试类实现JUnit测试套件，并同时运行它们。但是当我运行那个测试套件时，它给我错误，如初始化错误和“没有找到可运行的方法”。
这是我的测试套件类，名为AllTests.java

package Calendar.CalendarTesting;

import org.junit.runner.RunWith;

import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

@RunWith(Suite.class)
@SuiteClasses({JUnitTesting_AddPatientPage.class, JUnitTesting_DentalCategoryPage.class, JUnitTesting_LoginPage.class})
public class AllTests {

}

这是一个JUnitTesting_AddPatientPage类

package Calendar.CalendarTesting;
import static org.junit.Assert.assertEquals;
import static org.junit.jupiter.api.Assertions.assertNotEquals;

import org.junit.jupiter.api.Test;

public class JUnitTesting_AddPatientPage {

    AddPatient addPatientPage = new AddPatient();
    public  JUnitTesting_AddPatientPage()
    {}

    @Test
    public void SpecialityButtonGroupClearCheck() {
        assertEquals(null, AddPatient.Speciality.getSelection());
    }

    @Test
    public void PatientNameCheck() {
        assertNotEquals(null, addPatientPage.pnameTextField);   
    }

    @Test
    public void PatientAgeNullCheck() {
        assertNotEquals(null, addPatientPage.pageTextField);    
    }

    @Test
    public void PatientAgeValidCheck() {
        assertNotEquals(0, addPatientPage.pageTextField);   
    }

}

这是我的JUnitTesting_DentalCategoryPage.class

package Calendar.CalendarTesting;
import static org.junit.Assert.assertEquals;

import static org.junit.jupiter.api.Assertions.*;

import org.junit.jupiter.api.Test;

class JUnitTesting_DentalCategoryPage {

    DentalCategory dentalcategorypage = new DentalCategory("A", 58, "Dental");

    @Test
    public void CategoryButtonGroupClearCheck() {
        assertEquals(null, DentalCategory.Category.getSelection());
    }

    @Test
    public void RoutingDentalCheck() {
        assertEquals("Dental", dentalcategorypage.pspeciality);
    }

    @Test
    public void InitalRatingCheck() {
        assertEquals(0, dentalcategorypage.rating);
    }
}

这是我的JUnitTesting登录页面

package Calendar.CalendarTesting;
import static org.junit.Assert.assertEquals;

import static org.junit.jupiter.api.Assertions.*;

import org.junit.jupiter.api.Test;

public class JUnitTesting_LoginPage {

    LoginTest loginPage = new LoginTest();

    @Test
    public void LoginButtonDisableCheck() {
        assertEquals(false, loginPage.loginButton.isEnabled());
    }

    @Test
    public void ViewPasswordButtonDisableCheck() {
        assertEquals(false, loginPage.showPassword.isSelected());
    }

    @Test
    public void LoginNameCheck() {
        assertNotEquals(null, loginPage.usernameTextField); 
    }

    @Test
    public void LoginPasswordCheck() {
        assertNotEquals(null, loginPage.passwordField); 
    }
}

在运行ALLTests.java作为JUnit测试后，它给予我以下错误：-
