Usage

get_test_task(
  fake_data = NULL,
  fake_target = "target",
  training_fields = "feature",
  stage = "prepare",
  resampling_strategy = "holdout",
  processing_pipeline = mlr3pipelines::PipeOpNOP$new(),
  learner = mlr3::LearnerClassifFeatureless$new(),
  measures = mlr3::msr("classif.acc")
)

Arguments
