file_coverage: Calculate test coverage for sets of files
Description
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.
Usage
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
test_files
Character vector of test files with code to test the
functions
line_exclusions
a named list of files with the lines to exclude from
each file.
function_exclusions
a vector of regular expressions matching function
names to exclude. Example print\. to match print methods.
parent_env
The parent environment to use when sourcing the files.
