Answer 1

Just put these classes in a test suite file and testNG will take care of running the class which has the @BeforeSuite first, the classes which has @test next, followed by the class which has the @aftersuite tag.

<suite>
<test name ="myTest">
<classes>
<class name ="Class1"/> <!-- Class with @beforeSuite-->
<class name ="Class2"/> <!-- Class with @test-->
<class name ="Class3"/> <!-- Class with @afterSuite-->

</classes>
</test>
</suite>

By the way, why do you want to have different classes for @AfterSuite and @BeforeSuite methods. It would have been simpler if all are in the same class. But its just my thought.

I suggest the following:

1. Please go through this link , which is a very detailed documentation of TestNG. You can set the 'priority' attribute for the Test annotation.

    //this decides the order in which your tests are executed @test{priority=1} //executed first @test{priority=2} //executed second @test{priority=3} //executed third 

2. Since this looks like a keyword driven framework, I suggest you to pass the Class names from an excel sheet instead of implementing an XML parser.

3. To implement the excel sheet read/write, Apache POI is a very good library. It supports both xls and xlsx files. This way modifying the order of execution would also be easy. See this link for more info on a keyword driven framework.

4. As far as reporting structure goes, TestNG may generate its own report, but ATU Graphical Reporter has a nice visual appeal.

This is how to mention your tests in XML file:

<?xml version="1.0" encoding="UTF-8"?>
<suite name="SuiteName" verbose="1" data-provider-thread-count="10"
    thread-count="10">
    <test name="TestName" thread-count="10">
        <classes>
            <class name="packageName.ClassName"/>
            <class name="packageName.ClassName" />
        </classes>
    </test>
</suite>
