How to get handle of current running testNG instance...

[shankar KC]

Hi,
   I have a testsuite xml(Failed-testNG.xml) that gets generated dynamically and its not part of test source code. I want to use it as my testNG.xml.
I thought of doing this.

ArrayList<XmlSuite> arrayList = null;

        File failedxml = new File("failed-tesNG.xml");
        logInfo(tcID, "current DIR is " + failedxml.getAbsolutePath());
        if (failedxml.exists() && ReportingListener.maxRerunCount > 0) {
            try {
                arrayList = new ArrayList<XmlSuite>(new Parser(
                        "Failed.xml").parse());
            } catch (ParserConfigurationException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            } catch (SAXException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            } catch (IOException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }

            TestNG tng = this; // NEED TO GET CURRENT TESTNG INSTANCE and set its XML suite. Not sure how to refer current running testNG instance
            tng.setXmlSuites(arrayList);
.......
........
.......
 
        }
Can anybody guide me how to do it?

My used case scenario is this.
I have bunch of tests that run and some might fail due to environment issue. next day in the workspace i do see failed-testNG.xml produced. i want to rerun it. By default we select the testNG.xml defined in POM. i want to skip it and use the failed-testNG.xml. i assume user sets a SystemProperty called "usedFaildXML" to true. If so i will try to parse the xml and run the tests in it.
Thanks

Hi can anyone answer this?

Why not simply modify your build so it uses testng-failed.xml instead fo testng.xml?

Shankar,

Answer to your question : No you cannot get a handle to the currently running TestNG instance, because there is no mechanism defined in it.

If you are using maven, then you could essentially define a property as below :

<properties>

<testSuite>src/test/resources/suiteBuildTests.xml</testSuite>

</properties>

and then refer to this property value in your surefire plugin as below :

<suiteXmlFiles>

<suiteXmlFile>${testSuite}</suiteXmlFile>

</suiteXmlFiles>

In your continuous integration job, you can override the value for this property using the VM arg as 

-DtestSuite=faile-suite.xml

Wouldnt that help ?

Thanks & Regards

Yes it helps a bit. Ususally when you have multiple testNG suites failed-TestNG.xml produced for each suite and kept in output directory. So its possible that i might have to pass multiple testNG files. I am novice MAVEN user. Is it possible to pass multiple testNG files in some way?

Thanks Cédric. My intent is to provide user ease of use. Now to rerun(approach you suggested ) user need to gather multiple failed-testNG.xml from multiple folders and build/run again. I feel its bit painful. Programatically i can get failed testNGs. But i need to a)  clear the current testNG suite and b) set the failed-testNG.xml as current test suite. But i am not sure how to achieve it.
