Class execution order of TestNG tests

Question

I have read many of the articles out here on this topic and have yet to find the one that resolves my issue.

Goal:

Get test classes defined in testng.xml file to execute in order listed in the file.
Have all methods defined within each class fire in order listed (this works)
Only have a single browser window open at any given time (NO Parallel execution)

Each test class has an init method that initializes the browser, so I understand why I am getting n number of browser windows open right off the bat, one for each test class.

What I'd like to happen is...

Kick off Test Class A Run all methods in Test Class A Clsoe the browser via @AfterTest method in Test Class A Move on to Test Class B ...

I am hoping there is some way that I can get TestNG to do this. Also, I am kicking off the tests from maven command line using 'mvn test -Dbrowser=chrome' with the surefire plugin that calls on my defined TestNG.xml file.

Current TestNG.xml file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="Suite">
    <listeners>
        <listener class-name="com.infdig.qa.Listeners" />

Your TestNG xml runner file doesn't have an important parameters

preserve-order="true", to run by order. Here you can find more details.

I think you're mixing up the AfterTest method and AfterClass method, after test method will close your browser once, WHY? Because in the xml file you have 1 test tag only , AfterTest method is running accordingly to test tags. As you wrote I understand that you wanna run test methods of class A then of class B, to do that you must put each class tag inside test tag which means you have 4 class tags so that you need 4 test tags.

OR

You can keep the xml like above but you have to change AfterTest method to AfterClass.

Here are the annotations differences:

@AfterTest: The annotated method will be run after all the test methods belonging to the classes inside the tag have run.
@AfterClass: The annotated method will be run after all the test methods in the current class have been run.
@AfterMethod: The annotated method will be run after each test method.
