Run All or a Subset of the Tests Across Future Plans

check(
  plan = NULL,
  tags = character(),
  timeout = NULL,
  settings = TRUE,
  session_info = FALSE,
  envir = parent.frame(),
  local = TRUE,
  debug = FALSE,
  exit_value = !interactive(),
  .args = commandArgs()
)

Arguments

plan: (character vector) One or more future strategy plans to be validated.
tags: (character vector; optional) Filter test by tags. If NULL, all tests are performed.
timeout: (numeric; optional) Maximum time (in seconds) each test may run before a timeout error is produced.
settings: (logical) If TRUE, details on the settings are outputted before the tests start.
session_info: (logical) If TRUE, session information is outputted after the tests complete.
envir: The environment where tests are run.
local: Should tests be evaluated in a local environment or not.
debug: (logical) If TRUE, the raw test results are printed.
exit_value: (logical) If TRUE, and in a non-interactive session, then use base::quit() to quit R with an exit code of 0 (zero) if all tests passed with all OKs and otherwise 1 (one) if one or more test failed.
.args: (character vector; optional) Command-line arguments.

Value

(list; invisible) A list of test results.

Command-line interface (CLI)

This function can be called from the shell. To specify an argument, use the format --test-<arg_name>=<value>. For example, --test-timeout=600 will set argument timeout=600, and --tags=lazy,rng, or equivalently, --tags=lazy --tags=rng will set argument tags=c("lazy", "rng").

Here are some examples on how to call this function from the command line:


Rscript -e future.tests::check --args --test-plan=sequential
Rscript -e future.tests::check --args --test-plan=multicore,workers=2
Rscript -e future.tests::check --args --test-plan=sequential --test-plan=multicore,workers=2
Rscript -e future.tests::check --args --test-plan=future.callr::callr
Rscript -e future.tests::check --args --test-plan=future.batchtools::batchtools_local

The exit code will be 0 if all tests passed, otherwise 1. You can use for instance exit_code=$? to retrieve the exit code of the most recent call.

Examples

if (FALSE) {
results <- future.tests::check(plan = "sequential", tags = c("rng"))
exit_code <- attr(results, "exit_code")
if (exit_code != 0) stop("One or more tests failed")
}
