compute_test_files_clean_dt: Compute wrapper data.table test files to run for coverage...

In test.assessr: Assessing Package Test Reliability and Quality

Compute wrapper data.table test files to run for coverage (internal)

Description

Selects and sanitizes the list of **wrapper** test files to execute during coverage, supporting both the standard 'tests/' layout and the 'testit' layout ('tests/testit/'). When 'pkg_name' is '"data.table"', the function adds package-aware behavior: it falls back to 'tests/main.R' if the mapping yields no existing files and optionally prioritizes 'froll.R' so rolling function tests run early.

Usage

compute_test_files_clean_dt(
  pkg_name,
  pkg_source_path,
  clean_mapping,
  test_pkg_data,
  skip_tests = NULL
)

Arguments

pkg_name	'character(1)'. Package name.
pkg_source_path	'character(1)'. Absolute or relative path to the package source root.
clean_mapping	A data frame or list containing at least a 'test_file' column/element with **relative** wrapper paths to run. Paths are resolved against 'tests/' or 'tests/testit/' depending on 'test_pkg_data$has_testit'.
test_pkg_data	'list'. Must include logical flag 'has_testit' indicating whether the package uses a 'tests/testit/' layout.
skip_tests	'NULL' or 'character()'. Relative wrapper paths to exclude (matched within the chosen base directory).

Details

This helper **only resolves file paths**; it does **not** modify the evaluation environment, copy/mirror test assets, or toggle data.table's test harness mode. Any package-specific preparation (e.g., mirroring 'inst/tests/' to 'tests/' or exposing 'test.data.table()' in dev mode) must be handled elsewhere (see 'prepare_tests_for_package()').

Value

'character()' - **normalized**, de-duplicated vector of wrapper file paths that **exist** on disk. May be zero length if no candidates exist and no fallback is available.
