如何使用TestNG JAVA Reflection设置测试方法执行的优先级

Question

我试图在反射的帮助下执行我的测试脚本，反射注释为@test，如下所示：

Class<?> className = Class.forName(format);  //Load the class name at runtime

                Constructor<?> customConstructor = className.getConstructor(WebDriver.class);   //Create customized constructor and initalize driver from testbase


Method[] method = className.getMethods();  //Call the list of methods in current class file

                for (Method me : method) {
                    if (me.getName().startsWith("test")) {   //Check wheather the class prefix as test

                        Method getMethods = Class.forName(format).getDeclaredMethod(me.getName());   //Loading all the methods at runtime.
                        if(getMethods.isAnnotationPresent(Test.class))
                        {
//The method which is annotated @Test will execute here, using invoke() method of reflection.
}
}

但是，问题是无法按照优先级值运行@测试方法。它是随机执行的。谁能告诉我如何根据优先级值运行@测试方法吗。

此外，我也尝试了dependsOnMethods。但它仍然是随机执行的。

示例代码：

package com.test.build;

import com.test.build.ClassA;
import com.test.build.ClassB;

import java.lang.reflect.*;
import java.util.Scanner;

import org.testng.annotations.Test;

public class ParentClass {

    @Test
    public void executeTestMetods() throws Exception {
        Scanner scan = new Scanner(System.in);
        System.out.println("Type package name");
        String name = scan.next();
        Class<?> class1 = Class.forName(name);
        Method[] method = class1.getMethods();

        for (Method me : method) {
            if (me.isAnnotationPresent(Test.class)) {
                if (me.getName().startsWith("test")) {
                    System.out.println(me.getName());
                }
            }
        }
        scan.close();
    }
}

A类

package com.test.build;

import org.testng.annotations.Test; 

@Test(singleThreaded  = true)
public class ClassA {

    @Test(priority=0)
    public void test1()
    {
        System.out.println("class A");
    }

    @Test(priority=1)
    public void test2()
    {
        System.out.println("Class A second method");
    }

    @Test(priority=2)

    public void test3()
    {
        System.out.println("class A");
    }

    @Test(priority=3)
    public void test4()
    {
        System.out.println("Class A second method");
    }

    @Test(priority=4)

    public void test5()
    {
        System.out.println("class A");
    }

    @Test(priority=5)
    public void test6()
    {
        System.out.println("Class A second method");
    }

}

输出：

键入包名称com。测验建筑ClassA测试3测试4测试5测试6测试1测试2通过：executeTestMetods

=============================================默认测试

输出未按优先级正确执行，并显示随机调用。如何使其顺序执行？
