TestNG/Surefire: How to generate an XML report after each test?

Question

We have a large number of complex integration tests that run for several hours. How do I receive TestNG XML reports while the tests are running, not after the run?

Answer 1

You can build a TestNG listener which extends org.testng.TestListenerAdapter and override its org.testng.TestListenerAdapter#onFinish wherein you can build the logic to push the results of a <test> tag after its run to a data source of your own. You can also try making it more real-time by building an implementation of the listener interface org.testng.IInvokedMethodListener and within org.testng.IInvokedMethodListener#afterInvocation check if a method is a test method and if yes, start recording the results to a data source of your choice.
