Define a test implementation

test_define() declares a single implementation of a hypothesis test. Multiple test_define objects are passed to HTEST_FN() via defs. This is the main extension point for adding new tests or engines.

Usage

test_define(
  model_type = character(0),
  impl_class = character(0),
  impl = NULL,
  compatible_params = character(0),
  eval_claim = NULL
)

Arguments

model_type

A string matching the primary class of the model ID this implementation handles. E.g. "x_by", "pairwise".

impl_class

A string naming the implementation class. E.g. "ttest_two". Used in the S3 class vector of the result.

impl

An agendas() object declaring all implementations.

compatible_params

A character vector of ParamDef types this implementation can interpret via write_claim(). E.g. c("MU").

eval_claim

A function with signature function(self, claim) that interprets a ClaimDef for this implementation. NULL if write_claim() is not supported.

Value

A test_define S7 object.
