## Unit tests

DescrTab2 features a suite of unit tests. The percentage of lines of codes covered by at least one unit tests is reported via the covr package. Most of these unit tests only check whether the code associated with it produces errors. This aims to ensure that the various options in DescrTab2 work error-free with a variations of possible input datasets and edge-cases.

## Manual external software comparisons

Comparisons of the results produced by DescrTab2 with other software are not automated. The user may feel free to perform such comparisons by themselves. An exemplary comparison can be examined in this document.

## Dependencies

DescrTab2 relies on various other packages to perform its designated purpose. Most of the imported packages are neccesary to facilitate tasks related to data-wrangling and output formatting, namely ?utils, ?dplyr, ?rlang, ?tibble, ?stringr, ?forcats, ?magrittr, ?tidyselect, ?scales, ?cli, ?kableExtra, ?flextable and ?officer. The pre-implemented summary statistics (mean, sd, etc.) make use of functions provided for this purpose in base R (see ?base and ?stats). The test functions used for the calculcation of p-values are mostly from base R (e.g. ?t.test from ?stats) and the recommended packages (e.g. ?lme from ?nlme for the Mixed Model Anova p-value). Notable exceptions are the Cochrane Q Test from the ?DescTools package (?DescTools::CochranQTest) and the Fisher-Boschloo test from the ?exact2x2 package (?exact2x2::boschloo).
