How to set priority for test methods execution using TestNG + JAVA Reflection -

i have trying execute test script of reflections has annotated @test following way:

class<?> classname = class.forname(format);  //load class name @ runtime                  constructor<?> customconstructor = classname.getconstructor(webdriver.class);   //create customized constructor , initalize driver testbase   method[] method = classname.getmethods();  //call list of methods in current class file                  (method me : method) {                     if (me.getname().startswith("test")) {   //check wheather class prefix test                          method getmethods = class.forname(format).getdeclaredmethod(me.getname());   //loading methods @ runtime.                         if(getmethods.isannotationpresent(test.class))                         { //the method annotated @test execute here, using invoke() method of reflection. } } 

but, problem not able run @test methods per priority value. executing randomly. can tell me how run @test methods based on priority value.

also, tried same dependsonmethods. still randomly executing.

sample code:

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();          (method me : method) {             if (me.isannotationpresent(test.class)) {                 if (me.getname().startswith("test")) {                     system.out.println(me.getname());                 }             }         }         scan.close();     } } 

classa

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 second method");     }      @test(priority=2)      public void test3()     {         system.out.println("class a");     }      @test(priority=3)     public void test4()     {         system.out.println("class second method");     }      @test(priority=4)      public void test5()     {         system.out.println("class a");     }      @test(priority=5)     public void test6()     {         system.out.println("class second method");     }  } 

output:

type package name com.test.build.classa test3 test4 test5 test6 test1 test2 passed: executetestmetods

=============================================== default test

tests run: 1, failures: 0, skips: 0

the output not executed per priority, , shows randomly invoked. how make sequence execution?

testng provides inbox dedicated feature want: annotation transformers.
