run_covr_modes: Run Coverage Analysis with Test Detection

In test.assessr: Assessing Package Test Reliability and Quality

Run Coverage Analysis with Test Detection

Description

This function inspects the test configuration of an R package and runs code coverage analysis using any available testing framework, including 'testthat', 'testit', base R test scripts, or Bioconductor-style tests. If no recognised testing configuration is found, a default zero‑coverage result is returned.

Usage

run_covr_modes(pkg_source_path, covr_timeout = 60)

Arguments

pkg_source_path	Character. Path to the root directory of the package source.
covr_timeout	Numeric. Timeout in seconds for running coverage analysis. Default is 60.

Value

A named list containing coverage results, package metadata, and test configuration details. The returned list includes (but is not limited to):

pkg_name

Character. Package name extracted from the DESCRIPTION file.

pkg_ver

Character. Package version.

date_time

Timestamp of when the analysis was run.

executor

User or environment running the analysis.

sysname, version, release, machine

System metadata.

r_version

R version used during analysis.

test_framework_type

Character. Detected testing framework type.

covr_list

A nested list containing:

total_cov

Numeric. Aggregated coverage percentage.

res_cov

File‑level and line‑level coverage details.

errors, notes

Any warnings or notes detected during testing.

test_pkg_data

A list describing the test configuration of the package (presence of testthat, testit, base tests, snapshots, etc.).

This function always returns a value. When no supported testing framework is detected, a default object with zero coverage and diagnostic information is returned.

Examples

dp <- system.file("test-data", 
  "test.package.0001_0.1.0.tar.gz", 
  package = "test.assessr")

# set up package
install_list <- set_up_pkg(dp)

package_installed <- install_list$package_installed
pkg_source_path <- install_list$pkg_source_path

# install package locally to ensure test works
package_installed <- install_package_local(pkg_source_path)
package_installed <- TRUE

covr_mode_list <- run_covr_modes(pkg_source_path)
