Extend 'tinytest' with 'diffobj'.
ttdo: Extend 'tinytest' with 'diffobj'
What is it?
A package to extend tinytest, a lightweight, no-dependency, full-featured unit testing package, with diffobj which compares R objects with proper diff semantics.
So it tests and compares and, in case of differences, provides informative results.
What does that look like?
Glad you asked:
To test it out yourself, the code is in demo/expect_equal_with_diff.R. If you don't see the same results as above, you may need to manually adjust the diffobj package options. Try options(diffobj.format = "ansi256"). See Controlling Diffs and Their Appearance for more details.
How do install it?
The package is now on CRAN and can be installed via a standard
install.packages("ttdo")
Who wrote it?
Dirk Eddelbuettel and Alton Barbehenn
What license?
GPL (>= 2)
