Good usability.
The tool takes most of the cognitive effort for thinking about the implementation of my unit tests.
Their click&go method makes unit testing almost enjoyable.
The first unit testing tool that I've tried that I actually want to use in my dev workflow! Review collected by and hosted on G2.com.
It's only available for C# yet. Seems like they are working on Java as well based on their website. But as my clients usually require me to code in different languages , this limits its applicability for my projects. Review collected by and hosted on G2.com.
