How to run 2 testNG xml suites in sequential mode or parallel mode using batch file

How to run 2 testNG xml suites in sequential mode or parallel mode using batch file?

Let us consider below to be the content of 2 Test NG xmls

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="mySuite1"  thread-count="3">
<test name = "myTest">
<classes>
<class name="testNG.Test1"/>
</classes>
</test>
</suite>



<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="mySuite2"  thread-count="3">
<test name = "myTest2">
<classes>
<class name="testNG.Test2"/>
</classes>
</test>
</suite>

To run these 2 xmls in sequence, we can write a batch file with below content: 

set classpath="Path of Test NG libs\*;

cd directory classpath of TestNG class files

java org.testng.TestNG  TestNG_Parallel.xml TestNG_Parallel2.xml

Note here command java org.testng.TestNG xml1 xml2 will run suites in sequence. 

classpath = Here you need to set path of all libs that you are using in project. 

cd  directory must point to the class files path. 

Here is the sample output: 

Thread ID ------------1

test1

===============================================

mySuite1

Total tests run: 1, Failures: 0, Skips: 0

===============================================

Thread ID ------------1

test2

Thread ID ------------1

test3

===============================================

mySuite2

Total tests run: 2, Failures: 0, Skips: 0

===============================================

Note the Thread ID same for all tests because same thread was used for execution (Sequential). 

Now to run 2 xml suites in parallel just add -suitethreadpoolsize 2 option. So batch file would like like this: 

set classpath="Path of Test NG libs\*;

cd directory classpath of TestNG class files

java org.testng.TestNG   -suitethreadpoolsize 2 TestNG_Parallel.xml TestNG_Parallel2.xml

Below is the sample output: 

Thread ID ------------9

Thread ID ------------8

test1

test2

Thread ID ------------9

test3

===============================================

mySuite2

Total tests run: 2, Failures: 0, Skips: 0

===============================================

===============================================

mySuite1

Total tests run: 1, Failures: 0, Skips: 0

===============================================

Note the Thread ID is different for some tests because execution happened in parallel ( 8 and 9 ).
