R: Calculate test coverage for sets of files

file_coverage {covr} | R Documentation

## 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.
