### What is it?

A package to extend [tinytest](https://cran.r-project.org/package=tinytest), a lightweight, no-dependency, full-featured unit testing package, with

[diffobj](https://cran.r-project.org/package=diffobj) which compares [R](https://www.R-Project.org) 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:

![](https://eddelbuettel.github.io/ttdo/ttdoDemo.png)

To test it out yourself, the code is in

[demo/expect_equal_with_diff.R](https://github.com/eddelbuettel/ttdo/blob/master/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](https://cran.r-project.org/package=diffobj/vignettes/diffobj.html#controlling-diffs-and-their-appearance)

for more details.

### How do install it?

The package is now on [CRAN](https://cran.r-project.org) and can be installed

via a standard

```r

install.packages("ttdo")

```

### Who wrote it?

Dirk Eddelbuettel and Alton Barbehenn

### What license?

GPL (>= 2)

### Thanks go to

Mark van der Loo for the excellent

[tinytest](https://cran.r-project.org/package=tinytest) package, Brodie

Gaslam for the nifty [diffobj](https://cran.r-project.org/package=diffobj)

package and Michel Lang for

[checkmate.tinytest](https://github.com/mllg/checkmate.tinytest)
