you usually state the finding to which the test relates and then report the test statistic, its degrees of freedom and its probability value. This applies whether we use a t-test or a robust test. Ideally report an estimate of the effect size and the Bayes factor too. If you used a robust test you should cite R (R Core Team, 2016) and the WRS2 package (Mair, Schoenbrodt, & Wilcox, 2017), because that’s what was used to compute them.
