Capturing Human Intelligence - ApprovalTests is an open source assertion/verification library to aid unit testing.
It is compatible with most .Net unit testing frameworks (Nunit, MsTest, xUnit, MBUnit)

Approval Tests can be used for verifying objects that require more than a simple assert. They also come prepackaged with utilities for some common .Net scenarios including:
- Dictionaries & Collections
- Long Strings
- Log Files
- Asp.Net
- Asp.Net Mvc
- Winforms
- Wpf
- Entity Framework
- Rdlc reports
You can watch a bunch of short videos on getting started and using ApprovalTests in .Net at YouTube

[TestFixture]
public class SampleTest
{
[Test]
public void TestList()
{
var names = new[] {"Llewellyn", "James", "Dan", "Jason", "Katrina"};
Array.Sort(names);
Approvals.VerifyAll(names, "");
}
}Will Produce a File
SampleTest.TestList.received.txt
[0] = Dan
[1] = James
[2] = Jason
[3] = Katrina
[4] = Llewellyn
Simply rename this to SampleTest.TestList.approved.txt and the test will now pass.
The *.approved.* files must be checked into source your source control. ApprovalTests now ignores line endings by default (so you can remove *.approved.* binary from your .gitattributes file if you added previously).
If you would like to verify line endings, simply add [assembly: IgnoreLineEndingsAttribute(false)] to your AssemblyInfo.cs
Do not add *.received.* files to your source control (they are transitory, and some SCMs like TFS will lock them or mark them read-only, which will break every dependent test).
