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.
