Version 0.7.0 [2023-05-20]

Bug Fixes

  • Tests asserting correctness of nbrOfWorkers() could produce an "invalid format '%d'; use format %f, %e, %g or %a for numeric objects" error when trying to produce an assertion error on nbrOfWorkers() having an incorrect value. This could happen if nbrOfWorkers() returned a non-integer value, e.g. +Inf.

  • Test asserting that the workers argument can be a function would not always work if testing with a hardcoded number of workers according to plan().

  • Test asserting that the workers argument can be a function would not work if the backend's default value was non-numeric, e.g. the cluster backend defaults to the character vector parallelly::availableWorkers().

  • Test asserting that lazy futures would be automatically launched and resolved relied on a legacy version of the Future API, where calling resolved() on a lazy future could leave it in a lazy state, which is no longer correct. A lazy future will always be launched if one calls resolved() on it.

  • Test asserting that the ff package worked across multiple futures assumed that the package is loaded automatically by the future, which it is not. The could cause the test to fail for some future backends.

Version 0.6.0 [2023-03-11]

New Features

  • Now tests can be formally skipped by calling future.tests::skip_test() from within the test. Skipped tests are counted and reported in the summary.

  • Now check_plan() outputs the reason for a test is being skipped.

  • Now check_plan() outputs also the error message, error class, the call, and any standard output, whenever there's is a test error.

  • Now check_plan() outputs also the test iteration index.

  • Add Rscript -e future.tests::check --version.

Bug Fixes

  • Some tests assume that the future strategy tested has a workers argument, which is not true for all future backends. For example, 'sequential' does not take argument workers. Previously, we avoided this problem by only testing if the evaluator inherited multiprocess, but that is not sufficient, e.g. upcoming future.redis::redis inherits multiprocess, but still does not have a workers argument. Now we check for the workers argument instead.

Version 0.5.0 [2022-12-15]

New Tests

  • Assert that none of future(), run(), result() and value() update the RNG state.

Version 0.4.0 [2022-11-21]

New Tests

  • Assert that rm(a) in a future expression only removes a local variable a, but never a global variable a.

  • Assert that packages data.table and ff are not affected when a future resets the R options on the worker when resolved.

  • Assert that a global that is a copy of a non-exported package object (e.g. utils:::str2logical()) is not dropped because it belongs to a package namespace.

  • Assert that ... can be exported as a global to a future, and used as-is inside a function that does not have ... arguments.

New Features

  • check() and check_plan() gained argument local, which is passed down to run_test().

  • check() gained argument envir, which is passed down to run_test().

Bug Fixes

  • The TestResult class did not record whether the test was evaluated in a local environment or not.

  • A too strict internal assertion would give Error in evaluate_expr(test$expr, envir = envir, local = FALSE, output = output, : identical(Sys.getenv(), old$envvars) is not TRUE for R 4.2.x and R-devel on MS Windows. This was because it is not possible to remove environment variables on MS Windows; they can only be set to an empty value.

Version 0.3.0 [2021-10-09]

New Tests

  • Assert that future() doesn't change the RNG kind.

  • Assert that future(..., conditions = character(0L)) muffles all conditions.

New Features

  • For robustness, using explicit stringsAsFactors = FALSE internally.

  • evaluate_expr(), which is used for running all tests, now reset options, environment variables, the RNG kind, and the random seed afterward to what it was before being called.

  • Added a package vignettes.

Bug Fixes

  • Tests on resolve() would use deprecated argument value.

Version 0.2.1 [2020-03-19]

CRAN Re-submission Requests

  • Update the package description to use single quotes.

  • Add example to check().

Version 0.2.0 [2020-03-13]

  • First version released on CRAN.

Version 0.1.1 [2020-01-06]

Bug Fixes

  • Assert that resolved() will launch lazy futures.

Version 0.1.0 [2020-01-03]

New Features

  • In non-interactive mode, check() will quit R with an exit code that reflects whether all tests passed (0) or not (1).

  • check() gained arguments so that it can be easily called from R too.

Version 0.0.0-9000 [2017-05-16]

  • Created package stub.
