How to ensure that the order specified in TestNG.xml is retained?

On using TestNG+Selenium , I'm not able to ensure the order of execution of classes.The order specified below (in testng.xml) is not working ->ClassTwo executes first and then ClassOne is executed. 

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="ABC" parallel="">
  <test verbose="2" name="xyz" annotations="JDK" preserve-order="true">
    <classes>
      <class name="script.ClassOne"/>
      <class name="script.ClassTwo"/>
    </classes>
  </test>
</suite>

How can I ensure that the order specified in TestNG.xml is retained?

In TestNG, the order of execution is based on alphabetical order so we could use a TestNG attribute Priority and there we could mention which class->methods you want to execute first.This is Priority annotation attribute you could give in the @Test annotation.

example: @Test(Priority=-1)

Lesser the number value the first it will execute.

You just have to set parallel value to none 

<suite name="ABC" parallel="none">

it works for me !

....Quite a bit after the event but I had the same problem and found myself here.

In the end it was because the individual tests had been marked with a priority in the @Test annotation, so in my case but your example script.ClassTwo had a higher priority than script.ClassOne

Did you try @Test( dependsOnGroups= { "dummyGroupToMakeTestNGTreatThisAsDependentClass" } ) in the class?

See this thread: TestNG & Selenium: Separate tests into "groups", run ordered inside each group

Hope this helps!

According to TestNG documentation:

By default, TestNG will run your tests in the order they are found in the XML file. If you want the classes and methods listed in this file to be run in an unpredictable order, set the preserve-order attribute to false

I would suggest leaving the preserve-order attribute out, since it is set by default.

However, you have two other options to force specific order to the test methods/classes:

  1. Invoke tests programmatically.
  2. Implement method interceptor, that will order the list of the tests.
