Increase unit-tests coverage
As done with 'ggpp', unit tests need to be added to 'ggpmisc' so as to test the code better (in actual practice) and to achieve formally high coverage.
Now we have > 30% coverage overall, but > 95% coverage for recently written code.
The low coverage is in great part the result of calls to compute group and compute panel functions not being "seen" by the coverage estimate calculations. The only rather easy to implement solution seems to be to test these functions on their own, as they are named functions. It would help to add to them default arguments so that only the overrrideen arguments and data need to be passed arguments explicitly in the unit tests.
Added unit tests for Markdown encoded labels. They work with ggtext::geom_richtext, but seem to fail with the newborn marquee::geom_marquee().
To do:
- [x] Unit tests for label utilities
- [x] Unit tests for eq label utilities
- [x] Add Markdown tests for stat_correlation(), stat_poly_eq(), stat_quant_eq(), stat_ma_eq
- [x] Add default arguments to the compute-group functions
- [ ] Add tests for the compute-group functions
- [ ] Test coverage
