TestNG and surefire are not supporting the ${var} notation.

But you can use the filtering feature of Maven. Then you'll have to choose the modified resource:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>Test_Project</groupId>
<artifactId>TP_X</artifactId>
<version>1.0-SNAPSHOT</version>
  <build>
    <testResources>
        <testResource>
            <directory>src/test/resources</directory>
            <filtering>true</filtering>
        </testResource>
    </testResources>
    <sourceDirectory>${src.dir}</sourceDirectory>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.19.1</version>
            <configuration>
                <suiteXmlFiles>
                   <suiteXmlFile>target/test-classes/testng.xml</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>
    </plugins>
  </build>
</project>

Note the difference between testResources and resources: How do I filter test resources in maven?
