Selenium/testNG: How to run your test based on class priority and not on your method priorily from the XML file

Question

If have the following:

Class A
{ 
  Method M(priority = 2)
}

Class B
{ 
  Method M(priority = 1)
}

Then Class B is going to be executed before Class A. How can I execute Class A first?

The XML file that I am using is:

<classes>
  <class name="com.Users.Admin_ManageUsers_AR"/>
  <class name="com.Users.Admin_ManageUsers_AR"/>
</classes>

Best practice is to have each test be independent of the others so being able to run them in any order should be preferred. — JeffC, Dec 04 '17 at 15:38

Use group-by-instances="true" inside test tag of the testng.xml

Define your xml like below:

<test name="ManageUsersTest" group-by-instances="true">
    <classes>
        <class name="com.Users.Admin_ManageUsers_AR.ClassA" />
        <class name="com.Users.Admin_ManageUsers_AR.ClassB" />
    </classes>
</test>

I would go with group-by-instances as well as answered by others.

Alternatively, you could use groups and dependencies like this example in the documentation

<test name="ManageUsersTest">
  <groups>
    <dependencies>
      <group name="c" depends-on="a  b" />
      <group name="z" depends-on="c" />
    </dependencies>
  </groups>
</test>

The depends-on attribute contains a space-separated list of groups.

This gives you more control in case you have dependencies across classes.

An implicit way to prioritise test class execution is to add an alphabetically ordered prefix in class names. Like, you have test classes named : login , checkout, logout. Then rename them as TC01_login , TC02_checkout , TC03_logout. This will automatically prioritise the test execution as per the TC_{serial_number}

Use preserver-order in testng.xml file, then all classes will be executed in order provided in testng.xml

<test name="Regression" preserve-order="true">
<classes>
