<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.10</version>
<scope>test</scope>
</dependency>

#Sowjanya H M try adding the Java Test Runner extension. it supports running both junit and testng tests. If you have your pom setup correctly, you can execute all tests in your project by selecting your pom.xml and in the command dropdown selecting Run Code. I have a later version of testng in my pom dependencies section:
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.14.3</version>
</dependency>
then in your build section, you should have configuration plugins for maven-surefire and your testng xml files. something like:
<build>
<resources>
<resource>
<directory>src/test/resources</directory> #not required
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.0</version>
<configuration>
<!-- testng xml files for test execution -->
<suiteXmlFiles>
<suiteXmlFile>resources/sample.xml</suiteXmlFile>
</suiteXmlFiles>
</configuration>
</plugin>
</plugins>
</build>
