The generated file defaults to 'test.xml' if no filename is specified, but allows users to override the path (e.g. -jmytest.xml). The XML report captures individual test suite and subtest execution latency, alongside XML-escaped failure logs and skip reasons, while preserving the full multi-process concurrency speed of parallel test execution.
