## Setup `tinytest`

Setting up the `tinytest` framework is covered in detail in the documentation of tinytest. Quick summary:

1. In the package root directory, call `tinytest::setup_tinytest(".")`.
2. Edit/add R scripts with unit tests to the directory `inst/tinytest`.

## Setup `checkmate`

1. Edit your `DESCRIPTION` and add `checkmate` to `Suggests` unless it is already listed in `Imports` for its assertions.

2. In each test file which calls an expectation from `checkmate`, you must include the following lines at the beginning of the file:

       library("tinytest")
       library("checkmate")
       using("checkmate")

   If you forget the last line, expectations will not get reported correctly in the summary. Also note that sourcing a file which includes `using("checkmate")` is not sufficient.

3. Check if everything works with `R CMD check`.
