How xUnit eases Asp.Net Core development:
ASP.Net 5 is an open source software which helps in building modern web applications and can be run on Windows, Linux, and the Mac.
It also incorporates MV6 framework, which combines all the features of MVC and Web API into a single web programming framework.
.Net Core(formerly Net5):
.Net Core 1.0 (formally Asp.Net 5) helps even more on Automated Testing. Developers use xUnit for the testing, which provides an easy way to make testing automatic.
To make the automatic testing work, first, create a testing project like usual. Then new parameters such as Factor Theory will help to build the test procedures.
