Lazily prepare a single test

prepare_test() attaches a test specification to a <def_var> object, producing a test_lazy ready for optional recalibration with via() before being executed with conclude().

Usage

prepare_test(.x, .test, ...)

Arguments

.x

An S7 object extension yielded by, e.g. <def_var> object from define_model(), or an <expanded_model> object from write_models().

.test

A test function such as TTEST that carries <test_spec> objects when called.

...

Additional arguments passed to methods.

Value

A <test_lazy> S7 object.
