ℹ️ NUnit has now integrated this functionality, so I'm archiving the repo

Assertion-Source-Info

Adds the statement which caused the assertion failure to the assertion error message.

Example

Assert.That("baboon".IndexOf("boo"), Is.EqualTo(3));

The normal NUnit message would be of the form:

Expected 3 but was 2

With this test helper it's of the form:

In: Assert.That("baboon".IndexOf("boo"), Is.EqualTo(3)); Expected 3 but was 2

How to use with NUnit

[SetUpFixture]
public class AssemblySetUp
{
	[SetUp]
	public void SetUp()
	{
		Gtc.AssertionSourceInfo.AssertionImproverFixtureSetup.Install();
	}
	
	[TearDown]
	public void TearDown()
	{
		Gtc.AssertionSourceInfo.AssertionImproverFixtureSetup.Uninstall();
	}
}
