runittotestthat

Convert RUnit tests to testthat tests.

Installation

To install, you first need the devtools package.

install.packages("devtools")

Then you can install the runittotestthat package using

library(devtools)
install_github("richierocks/runittotestthat")

Converting tests

There are three functions of interest:

1. convert_test converts an individual RUnit test to a call to a testthat test.

   test_truth <- function()
   {
     x <- all(runif(10) > 0)
     checkTrue(x)
   }
   convert_test(test_truth)
   ## test_that("test_truth", {
   ##     x <- all(runif(10) > 0)
   ##     expect_true(x)
   ## })
   
   test_equality <- function()
   {
     x <- sqrt(1:5)
     expected <- c(1, 4, 9, 16, 25)
     checkEquals(expected, x ^ 4)
   }
   convert_test(test_equality)
   ## test_that("test_equality", {
   ##     x <- sqrt(1:5)
   ##     expected <- c(1, 4, 9, 16, 25)
   ##     expect_equal(x^4, expected)
   ## })
   
   test_error <- function()
   {
     checkException("1" + "2")
   }
   convert_test(test_error)
   ## test_that("test_error", {
   ##     expect_error("1" + "2")
   ## })
   

2. convert_test_file sources all the tests in a file, converts each one, then outputs them to a file (or file connection; stdout by default).

3. convert_package_tests takes a string naming a package, or a devtools::package object and loops over the files in inst/tests (or wherever you specify), converting the tests, and outputting to files or stdout.
