In richierocks/runittotestthat: Convert 'RUnit' Test Functions into 'testthat' Tests

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.

   ```{r} 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.
