Creates mock cdm object for testing

Creates a mock cdm with two default synthetic cohorts, one is the index cohort and the other one is the marker cohort. However the users could specify them should they wish.

Usage

mockCohortSymmetry(
  seed = 1,
  indexCohort = NULL,
  markerCohort = NULL,
  con = DBI::dbConnect(duckdb::duckdb(), ":memory:"),
  schema = "main"
)

Arguments

seed

The seed to be inputted.

indexCohort

The tibble of your index cohort. Default is NULL, which means the default indexCohort is being used.

markerCohort

The tibble of your marker cohort. Default is NULL, which means the default markerCohort is being used.

con

Connection detail.

schema

Name of your write schema.

Value

A mock cdm object contains your index and marker cohort
