NFluent will make your testsfluent to write: with a super-duper-happy auto-completion 'dot' experience. Indeed, just type the Check.That( followed by one of your object and a dot, and your IDE will show you all the checks available for the type of the given object to verify. No more, no less (i.e. no auto completion flooding).fluent to read: very close to plain English, making it easier for non-technical people to read test code.fluent to troubleshoot: every failing check of the NFluent library throws an Exception with a crystal-clear message status to ease your TDD experience (see examples below). Thus, no need to set a breakpoint and to debug in order to be able to figure out what went wrong.helpful to reverse engineer legacy code: indeed, temporarily write an on-purpose failing assert on a legacy method, so you can understand it and leverage on the "ready-to-be-copied-and-paste-for-arrays-or-collections-initialization-purpose" NFluent assert failure messages.less error-prone: indeed, no more confusion about the order of the "expected" and "actual" values you can find in the classical .NET unit tests frameworks.
