Unable to set the invocation count using maven/testng with Java

[Ann Millikin]

Good morning,

I am using TestNG (version 6.8) to set up an selenium automation framework using Java and Maven with a multi-threaded driver on the Grid.  I would like to override the invocation count by specifying a -Dparameter at the command line using maven (mvn).  For example, if I run the following:

mvn clean test -Dgroups=regression -DpositiveTestsToRun=5

I would like the 5 to set how many times the @Test for positiveTests runs.

I've tried this using this in an @BeforeMethod but I don't know how to pass the first argument (the bold null) which is the annotation.  (Btw please excuse the formatting)

@BeforeMethod(alwaysRun = true)

public void beforeMethod(ITestContext context)

{

ITestNGMethod currentTestNGMethod = null;

for (ITestNGMethod testNGMethod : context.getAllTestMethods())

{

if (testNGMethod.getInstance() == this)

{

currentTestNGMethod = testNGMethod;

TestNG tng = new TestNG();

tng.setAnnotationTransformer(new MyTransformer(null, currentTestNGMethod.getRealClass(), null, null));

}

}

}

I've also tried using the ITestNGMethod as follows but it doesn't work either:

// Issue with the below when using both ITestAnnotation annotation,

// ITestContext context

// must be supplied as @Parameters or in @Configuration but googling says

// @Configuration is deprecated

@BeforeMethod(alwaysRun = true)

public void beforeMethod2(ITestContext context)

// ITestAnnotation annotation,

{

ITestNGMethod currentTestNGMethod = null;

System.out.println("============= TestNGMethod.class: " + ITestNGMethod.class);

for (ITestNGMethod testNGMethod : context.getAllTestMethods())

{

if (testNGMethod.getInstance() == this)

{

currentTestNGMethod = testNGMethod;

System.out.println("-------- currentTestNGMethod: " + currentTestNGMethod);

/////////////// doesn't work

currentTestNGMethod.setInvocationCount(getPositiveTestsToRun());

break;

}

}

System.out

.println("============= in @BeforeMethod of DriverBase positiveTestsToRun: " + getPositiveTestsToRun());

// TestNgListener.getTestMethod().setInvocationCount(getPositiveTestsToRun());

System.out.println("=== currentTestNGMethod.getInvocationCount(): " + currentTestNGMethod.getInvocationCount());

System.out.println("currentTestNGMethod.toString(): " + currentTestNGMethod.toString());

}

I've tried so many things to no avail.  Any help would be appreciated!

Best regards,

Ann

Can you override the transform method provided by IAnnotationTransformer by writing your own listener and then use the listener later in the pom?
 

@Override
        public void transform(ITestAnnotation arg0, Class arg1, Constructor arg2,
                        Method arg3) {
                arg0.setInvocationTimeOut(System.getProperty('timeout'));
                arg0.setInvocationCount(System.getProperty('positiveTestsToRun'));
            LOG.info("Invoking method " + arg3.getName() + " for " + configarr[0] + " times with timeout " + configarr[1] );
        }

<properties>
                                                <property>
                                                        <name>listener</name>
                                                        <value>org.uncommons.reportng.HTMLReporter,org.uncommons.reportng.JUnitXMLReporter,src.TestNGTransformer</value>
                                                </property>
                                        </properties>
