(Code testing in R with the testthat package)


 


Abstract:

This unit discusses how to put tests in R into practice with the testthat package.

Objectives:
This unit will ...

  • ... introduce the testthat package;
  • ... teach how to write tests;
  • ... demonstrate best practice to organize your tests.

Outcomes:
After working through this unit you ...

  • ... can write your own tests;
  • ... can organize your tests in files and a testing directory to simplify running them.

Deliverables:

  • Time management: Before you begin, estimate how long it will take you to complete this unit. Then, record in your course journal: the number of hours you estimated, the number of hours you worked on the unit, and the amount of time that passed between start and completion of this unit.
  • Journal: Document your progress in your Course Journal. Some tasks may ask you to include specific items in your journal. Don't overlook these.
  • Insights: If you find something particularly noteworthy about this unit, make a note in your insights! page.
