19. Maven with Testng

In maven with testng we assume that you already are working in testng and upgrading to maven .

1. Create a maven project .

2. Except your test package copy all package to src/main/java

3. Copy your test package to src/main/test .

4. Configure your testng.xml file

e.g.

<?xml version="1.0" encoding="UTF-8"?>
<suite name="MyCol Front ">
	<parameter name="appURL" value="http://test.com/" />
	<parameter name="browserType" value="firefox" />

		<test name="CreateAnAccount">
		<classes>
			<class name="com.maven.tests.CreateAnAccounTest" />
		</classes>
	</test>
	</suite>

20. Configure pom.xml file

In Pom we have to write all dependencies that you are using in your project and plug in that you are using in your project .
See below code, if you using logging than you have to mention these dependencies .
If you are using another plugin that dependencies not displayed in pom than you should add it in pom file .
