How to pass java code a parameter from maven for testing - maven

Question

I need to pass on following values …
exeEvironment (Test environment) ,
testGroup (Group in testNG)
from Command-Line -> POM -> TestNG -> Test cases.
Based on these two posts ....
pass a java parameter from maven
How to pass parameters to guicified TestNG test from Surefire Maven plugin?
I did the following configuration ..
In surefire plugin, I tried following two options, none seem to work.
=====
(1)
<execution>
<id>default-test</id>
<goals>
<goal>test</goal>
</goals>
<configuration>
<properties>
<exeEnvironment>${exeEnvironment}</exeEnvironment>
<testGroup>${testGroup}</testGroup>
</properties>
<suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles>
</configuration>
</execution>
(2)
<execution>
<id>default-test</id>
<goals>
<goal>test</goal>
</goals>
<configuration>
<systemPropertyVariables> <exeEnvironment>${exeEnvironment}</exeEnvironment>
<testGroup>${testGroup}</testGroup> </systemPropertyVariables>
<suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles>
</configuration>
</execution>
In testNG.xml , can I use the the variable testGroup like …
<test name="Web Build Acceptance">
<groups>
<run>
<include name="${testGroup} />
</run>
</groups>
<classes>
<class name="com.abc.pqr" />
</classes>
</test>
This doesn't seem to work as well, do I need to define a parameter.
In the test cases , I tried to get he variables in following two ways ….
(1)
testEnv = testContext.getSuite().getParameter("exeEnvironment");
testGroup = testContext.getSuite().getParameter("testGroup");
(2)
testEnv = System.getProperty("exeEnvironment");
testGroup = System.getProperty("testGroup");

Answer 1

This is the exact thing I was looking for my automation test and I got it working.
Command Line argument
mvn clean test -Denv.USER=UAT -Dgroups=Sniff
My Pom Xml
<?xml version="1.0" encoding="UTF-8"?>
<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>TestNg</groupId>
<artifactId>TestNg</artifactId>
<version>1.0</version>
<dependencies>
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.8</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.12.4</version>
<configuration>
<systemPropertyVariables>
<environment>${env.USER}</environment>
</systemPropertyVariables>
</configuration>
</plugin>
</plugins>
</build>
</project>
TestNG test
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;
public class TestAuthentication {
#Test (groups = { "Sniff", "Regression" })
public void validAuthenticationTest(){
System.out.println(" Sniff + Regression" + System.getProperty("environment"));
}
#Test (groups = { "Regression" },parameters = {"environment"})
public void failedAuthenticationTest(String environment){
System.out.println("Regression-"+environment);
}
#Parameters("environment")
#Test (groups = { "Sniff"})
public void newUserAuthenticationTest(String environment){
System.out.println("Sniff-"+environment);
}
}
The above works well. Additionally, if you need to use testng.xml, you can specify the suiteXmlFile like ...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.12.4</version>
<configuration>
<systemPropertyVariables>
<environment>${env.USER}</environment>
</systemPropertyVariables>
<suiteXmlFiles>
<suiteXmlFile>testng.xml</suiteXmlFile>
</suiteXmlFiles>
</configuration>
</plugin>
Also, I prefer using #Parameters instead of parameters in #Test() as the later is deprecated.

You need not define anything for groups in testng xml or the pom, the support comes inbuilt. You can simply specify the groups on the cmd line
http://maven.apache.org/plugins/maven-surefire-plugin/test-mojo.html#groups
Hope it helps..
Edit 2:
Ok..so here's another option...Implement IMethodInterceptor
Define your custom property.
Use -Dcustomproperty=groupthatneedstoberun in your command line call.
In the intercept call, scan through all methods ..something to the effect..
System.getProperty("customproperty");
for(IMethodInstance ins : methods) {
if(ins.getMethod().getGroups()) contains group)
Add to returnedVal;
}
return returnedVal;
Add this to the listeners list in your xml.

Answer 3

Perfect.
The simplest way to pass the variable from POM.xml to ABC.java
POM.xml
<properties>
<hostName>myhostname.com</hostName>
</properties>
And in the ABC.java we can call it from the system properties like this
System.getProperty("hostName")

Answer 4

Passing parameter like browser and other can be done as below :
<properties>
<BrowserName></BrowserName>
<TestRunID></TestRunID>
</properties>
<!-- Below plug-in is used to execute tests -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<suiteXmlFiles>
<suiteXmlFile>src/test/resources/${testXml}</suiteXmlFile>
</suiteXmlFiles>
<systemPropertyVariables>
<browserName>${BrowserName}</browserName>
<testRunID>${TestRunID}</testRunID>
</systemPropertyVariables>
</configuration>
<executions>
<execution>
<id>surefire-it</id>
<phase>integration-test</phase>
<goals>
<goal>test</goal>
</goals>
<configuration>
<skip>false</skip>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</execution>
</executions>
</plugin>
and to handle this in java code use this :
public static final String Browser_Jenkin=System.getProperty("BrowserName");
public static final String TestRunID=System.getProperty("TestRunID");
public static String browser_Setter()
{
String value=null;
try {
if(!Browser_Jenkin.isEmpty())
{
value = Browser_Jenkin;
}
} catch (Exception e) {
value =propObj.getProperty("BROWSER");
}
return value;
}
public static String testRunID_Setter()
{
String value=null;
try {
if(!TestRunID.isEmpty())
{
value = TestRunID;
}
} catch (Exception e) {
value =propObj.getProperty("TEST_RUN_ID");
}
return value;
}

building on the accepted answer
if maven surefire and the <systemPropertyVariables> are declared in a maven profile, they are not available and will return null unless the profile is also invoked.
Command Line argument
mvn clean test -PmyTestProfile -Denv.USER=UAT -Dgroups=Sniff
pom.xml
<profiles>
<profile>
<id>myTestProfile</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>${surefire.version}</version>
<configuration>
<systemPropertyVariables>
<environment>${env.USER}</environment>
</systemPropertyVariables>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>

You don't need to use environment variables or edit pom.xml to use them.
The goals and options for Invoke Maven 3 under Build section takes the parameter. Try this (assuming you parameterized the build):
Invoke Maven 3
Goals and options = test -Denv=$PARAM_ENV -Dgroup=$PARAM_GROUP
