Tocsoft.DateTimeAbstractions

Tocsoft.DateTimeAbstractions is a testable alternative to the static DateTime.Now and DateTimeOffset.Now methods.

Installation

We also have a MyGet package repository - for bleeding-edge / development NuGet releases.

Usage

Using Tocsoft.DateTimeAbstractions is as simple as switching out all usages of DateTime.Now with Clock.Now and your done your businesslogic thats dependent of on getting the current time is now more testable.

Using Tocsoft.DateTimeAbstractions from Tests

Now your code is using Clock.Now you can now wrap your code under test like so

using (Clock.Pin(new DateTime(2018, 02, 02))) 
{  
	// Clock.Now will always return the pinned value until the using block has ended.
	Assert.Equal(new DateTime(2018, 02, 02), Clock.Now);
}

Additional APIs

You probably aren't using DateTime.Now in you code so how can this library help? well we support all the static properties from DateTime and DateTimeOffset so any of this properties can be switched out and tested.

System API	DateTimeAbstractions Replacement
DateTime.Now	Clock.Now
DateTime.UtcNow	Clock.UtcNow
DateTime.Today	Clock.Today
DateTimeOffset.Now	ClockOffset.Now
DateTimeOffset.UtcNow	ClockOffset.UtcNow

We include warnings and code fixes for all these mappings.

In addition to the DateTime set of APIs we also include a testable wrapper around using the Stopwatch class in the form of the ClockTimer as with the Clock APIs we support pinning for testing purposes.
