Unit test helpers

Description

Local helper functions for package unit tests

Usage

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

local_bru_testthat_tolerances(
  tolerances = c(0.0001, 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_mrsea_convert(x, use_km = FALSE)

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.

Details

local_bru_options_set() is used to set global package options.

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(): Calls bru_options_set() in a reversible way

• 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.

bru_options_set(), bru_options_default(), bru_options_get()

Examples

my_fun <- function(val) {
  local_bru_options_set(bru_verbose = val)
  bru_options_get("bru_verbose")
}
# Inside the function, the bru_verbose option is changed.
# Outside the function, the bru_verbose option is unchanged.
print(my_fun(TRUE))
print(bru_options_get("bru_verbose"))
print(my_fun(FALSE))
print(bru_options_get("bru_verbose"))
