     * Whether reruns or retries of a test should be merged into a combined testcase.

     * When enabled, the XML output will be very similar to the surefire plugin of Apache Maven™ when enabling reruns.
     * If a test fails but is then retried and succeeds, its failures will be recorded as {@code <flakyFailure>}
     * instead of {@code <failure>}, within one {@code <testcase>}.
     * This can be important for build tooling that uses this XML to understand test results,
     * and where distinguishing such passed-on-retry outcomes is important.
     * This is the case for the Jenkins CI server and its Flaky Test Handler plugin.
     *
     * This value defaults to {@code false}, causing each test execution to be a discrete {@code <testcase>}.
