TestNG: Multiple suite files are not running but single xml file is running multiple times

Question

This is my testng.xml file:

<suite name="Suite1" verbose="1" parallel="true" thread-count="5">
    <suite-files>
        <suite-file path="xml-files/live.xml"></suite-file>
        <suite-file path="xml-files/test.xml"></suite-file>
    </suite-files>
</suite>

I want to run both these xml and though it does start running but the problem is, it only runs single file(test.xml) two times. does anyone have idea why is it happening?

Update: Added pom, live and test.xml files

Answer 1

First of all you need to configure live.xml file and test.xml file in your pom.xml file using maven-surefire-plugin. You can do it in following way after your </dependencies> tag.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.20.1</version>
            <configuration>
                <suiteXmlFiles>
                    <suiteXmlFile>"xml-files/live.xml"</suiteXmlFile>
                    <suiteXmlFile>"xml-files/test.xml"</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>
    </plugins>
</build>

Then next you can run your testng.xml as it is..

Answer 2

You can try below approach which will help you execute to run multiple testNg.xml file together

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import org.testng.TestNG;

public class TestNGRunner {

    public static void main(String[] args) {

//Place all your multiple testng.xml suit file this progarm will it'self take care and execute one by one in single go of execution 
        String currentDir = System.getProperty("user.dir")+ "/src/test/resources/testRunners";

        File directory = new File(currentDir);

        File[] listOfFiles = directory.listFiles();
        List<String> suitFiles = new ArrayList<>();

        for (File file : listOfFiles) {
            suitFiles.add(currentDir + "/" + file.getName());
            System.out.println(file.getName());
        }

        TestNG runner = new TestNG();
        runner.setTestSuites(suitFiles);

        runner.run();

    }

}
