This repository contains code presented on a skyrise.tech blog article:
Extending NUnit 3 with command wrappers
It contains implementation and integration tests for a Retrying attribute, which retries failing tests. It was created, because NUnit's Retry attribute only retries tests on assertion failures, and not on other exceptions (as of 2017). This can be really inconvenient, especially with end-to-end tests.
Mind, that this is a POC that was created to present some techniques introduced in the blog post. I haven't published it on NuGet since it may lack some final touches. However, if you're interested in using it or writing and testing your own NUnit attributes, feel free to use this code as you wish.
