Я создаю юнит-тесты для R-пакета, который я разрабатываю. Я использую testthat, а для некоторых функций я использую testthat::expect_known_value()
. Я сохраняю справочные файлы, созданные expect_known_value(), в папке внутри папки testthat "package / tests / testthat/ reference_files "
Два моих модульных теста выглядят так:
test_that("project_single_joint_to_MP works when .method is 'first_last'", {
df <- dplyr::filter(mocapr::mocapr_data, movement_nr == 11)
expect_known_value(project_single_joint_to_MP(df, LSX, LSY, LSZ, "LS", .method = "first_last"), here::here("tests", "testthat", "reference_files", "first_last"))
})
test_that("project_single_joint_to_MP works when .method is 'first_dist'", {
df <- dplyr::filter(mocapr::mocapr_data, movement_nr == 11)
expect_known_value(project_single_joint_to_MP(df, LSX, LSY, LSZ, "LS", .method = "first_dist"), here::here("tests", "testthat", "reference_files", "first_dist"))
})
Я не получаю никаких ошибок при выполнении devtools::test() или devtools::test_coverage(), но когда я запускаю devtools::check(), двамодульные тесты завершаются неудачно с этим сообщением:
-- 1. Error: project_single_joint_to_MP works when .method is 'first_last' (@test-project_to_MP.R#12) -------------------------------------------------------------------

1: expect_known_value(project_single_joint_to_MP(df, LSX, LSY, LSZ, "LS", .method = "first_last"), here::here("tests", "testthat", "reference_files", "first_last")) at testthat/test-project_to_MP.R:12
2: saveRDS(object, file, version = version)
3: gzfile(file, mode)

Я нашел несколько ответов на похожие вопросы и проблемы , которые предлагают добавить Sys.setenv(R_TESTS="") или Sys.setenv("R_TESTS" = "") кПервая строка в testthat.R, но это ничего не меняет.
Где разместить эталонные файлы, чтобы devtools::check() мог их открыть?
Я запускаю Rstudio в режиме администратора, если это уместно.
