check_pkg_tests_and_snaps: Check for Testing Infrastructure and Snapshot Files

Description

This function inspects an R package source tree and detects the presence of common testing frameworks (`testthat`, `testit`, base R tests, BioGenerics/Bioconductor-style tests) as well as snapshot files used for golden testing.

Usage

check_pkg_tests_and_snaps(pkg_source_path)

Value

A list containing logical indicators and file counts describing the test configuration of the package. The list includes:

has_testthat

Logical. Whether `tests/testthat/` exists.

has_testit

Logical. Whether `tests/testit/` exists.

has_tests_base

Logical. Whether base R test files exist in `tests/`.

has_BioG_test

Logical. Whether BioGenerics-style tests exist in `inst/tests/`.

bioc_unit_tests_dir

Character. Path to BioGenerics unit test directory (if any).

bioc_run_ut_path

Character. Path to BioGenerics `run_unitTests.R` (if any).

has_snaps

Logical. Whether `_snaps/` exists inside `tests/testthat/`.

n_golden_tests

Integer. Number of snapshot test files inside `_snaps/`.

n_test_files

Integer. Number of `test-*.R` files in `tests/testthat/`.

This function always returns a value. It does **not** perform side effects other than reading the package directory structure.

Arguments

pkg_source_path

Character. Path to the root of the package source.

Examples

# \donttest{
# Adjust CRAN repo (example only)
r <- getOption("repos")
r["CRAN"] <- "http://cran.us.r-project.org"
old <- options(repos = r)

# Example package contained in test.assessr
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)
pkg_source_path <- install_list$pkg_source_path

# Install package locally (ensures correct test paths)
install_package_local(pkg_source_path)

# Detect tests and snapshots
test_pkg_data <- check_pkg_tests_and_snaps(pkg_source_path)

# Restore options
options(old)
# }
