The files in source_files are first sourced into a new environment to define functions to be checked. Then they are instrumented to track coverage and the files in test_files are sourced.

file_coverage(
source_files,
test_files,
line_exclusions = NULL,
function_exclusions = NULL,
parent_env = parent.frame()
)

## Arguments

source_files Character vector of source files with function definitions to measure coverage Character vector of test files with code to test the functions a named list of files with the lines to exclude from each file. a vector of regular expressions matching function names to exclude. Example print\\\. to match print methods. The parent environment to use when sourcing the files.
