This project contains the xUnit.net assertion library source code, intended to be used as a Git submodule.
To open an issue for this project, please visit the core xUnit.net project issue tracker.
The following pre-processor directives can be used to influence the resulting code contained in this repository:
Projects that consume this repository as source, which are compiled using C# 8 and wish to use nullable reference type annotations should define the XUNIT_NULLABLE
compilation symbol to opt-in to the relevant nullability analysis annotations on method signatures.
The Skip family of assertions (like Assert.Skip
) require xUnit.net v3. Define this to enable the Skip assertions.
There are optimized versions of Assert.Equal
for arrays which use Span<T>
- and/or Memory<T>
-based comparison options. If you are using a target framework that supports Span<T>
and Memory<T>
, you should define XUNIT_SPAN
to enable these new assertions.
Any asynchronous assertion API (like Assert.ThrowsAsync
) is available with versions that consume Task
or Task<T>
. If you are using a target framework and compiler that support ValueTask<T>
, you should define XUNIT_VALUETASK
to enable additional versions of those assertions that will consume ValueTask
and/or ValueTask<T>
.
By default, the Assert
class has public
visibility. This is appropriate for the default usage (as a shipped library). If your consumption of Assert
via source is intended to be local to a single library, you should define XUNIT_VISIBILITY_INTERNAL
to move the visibility of the Assert
class to internal
.
xUnit.net is a free, open source, community-focused unit testing tool for the .NET Framework. Written by the original inventor of NUnit v2, xUnit.net is the latest technology for unit testing C#, F#, VB.NET and other .NET languages. xUnit.net works with ReSharper, CodeRush, TestDriven.NET and Xamarin. It is part of the .NET Foundation, and operates under their code of conduct. It is licensed under Apache 2 (an OSI approved license).
