Local helper functions for package unit tests

Usage

local_bru_testthat_assign(x, values, envir = parent.frame())

local_bru_testthat_tolerances(
  tolerances = c(1e-04, 0.01, 0.1),
  envir = parent.frame()
)

local_bru_options_set(..., .reset = FALSE, envir = parent.frame())

local_basic_intercept_testdata()

local_basic_fixed_effect_testdata()

local_bru_safe_inla(multicore = FALSE, quietly = TRUE, envir = parent.frame())

local_bru_testthat_setup(envir = parent.frame())

Arguments

x

character; Name of variable to assign to

values

the object to assign to x

envir

environment for exit handlers

tolerances

numeric vector of length 3; [lowtol, midtol, hitol]

.reset

For local_bru_options_set, logical indicating if the global override options list should be emptied before setting the new option(s).

multicore

logical; if TRUE, multiple cores are allowed, and the INLA num.threads option is not checked or altered. Default: FALSE, multicore not allowed (used for examples and unit tests).

quietly

logical; if TRUE, prints diagnostic messages. A message is always printed if the INLA num.threads option is altered, regardless of the quietly argument. Default: TRUE.

Value

local_bru_options_set() returns a copy of the global override options (not including the defaults), invisibly.

Functions

  • local_bru_testthat_assign(): Assign local variable. Useful for easy cleanup of global workspace with withr::deferred_run() when running tests interactively.

  • local_bru_testthat_tolerances(): Assign test tolerances Assign local tolerance variables. Useful for easy cleanup of global workspace with withr::deferred_run() when running tests interactively.

  • local_bru_options_set(): Wrapper for bru_options_set_local(), to locally override the global package options.

  • local_bru_safe_inla(): Tests should set num.threads = "1:1" to ensure within-system repeatability by calling local_bru_safe_inla(); see also bru_safe_inla()

  • local_bru_testthat_setup(): Initialise environment for tests. Assigns tolerance variables. To be called either at the top of a testfile, or inside tests. Does not call local_bru_safe_inla(), since that may invoke a skip and should be called inside each test that relies on INLA.
