How to pass java code a parameter from maven for testing

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");

Solution 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

                    <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.

Solution 2:

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.
