Hi,
Gauge allows you to choose any framework for asserting on expectations. That being said, most of Gauge's use case are one or other form of
Black Box testing. Which implies that Gauge usually tests an application at a higher level while code coverage is usually a metric tracked at Unit testing level.
Hence, gathering code coverage is not something that we expect Gauge to do, unless you have a use case that we are overlooking here. If it is functional automation, then code coverage is a difficult metric to collect.
I suppose, technically it is possible to instrument a process under test, to profile the code that is executed under a given workflow and gather coverage, but I don't know if such a metric would be effective.
Hope this helps.
Best Regards
