mapping tests to code lines #10
Description
covr does not have the ability to produce this mapping. if desired, we'd need to build this ourselves. possibly like
test_file = "tests/testthat/test-geo_linestring.R"
x = covr::file_coverage("R/geo_linestring.R", test_file)
df = covr::tally_coverage(x)
df$test_file = basename(test_file)
# some lines below deleted for brevity
#> filename functions line value test_file
#> 1 R/geo_linestring.R geo_linestring 23 1 test-geo_linestring.R
#> 6 R/geo_linestring.R geo_linestring 28 0 test-geo_linestring.R
#> 11 R/geo_linestring.R geo_linestring 34 1 test-geo_linestring.R
#> 12 R/geo_linestring.R geo_linestring 36 1 test-geo_linestring.R
#> 13 R/geo_linestring.R geo_linestring 37 9 test-geo_linestring.R
#> 19 R/geo_linestring.R initial_bearing 49 9 test-geo_linestring.R
#> 21 R/geo_linestring.R initial_bearing 51 9 test-geo_linestring.R
#> 25 R/geo_linestring.R final_bearing 58 9 test-geo_linestring.R
#> 26 R/geo_linestring.R final_bearing 59 9 test-geo_linestring.Rthen at least we can only run certain test files (e.g., test-geo_linestring.R) we know are testing lines in which a mutation is located
don't think there's any way to just run specific test_that blocks within test files, and probably not a good idea anyway since there could be setup stuff we miss
