Support configurable name for XUnit reporter #2628
Description
The XUnit reporter produces an XML report that has a hard-coded name 'Mocha Tests'. In the XML this appears as: <testsuite name="Mocha Tests". When using mocha for various types of tests in the same CI build, it would be great to be able to specify this name to something more descriptive, e.g. "Unit Tests", "Integration Tests", etc.
