Documentation

Features
- Source generated tests
- Full async support
- Parallel by default, with mechanisms to switch it off for certain tests
- Test ordering (if running not in parallel)
- Tests can depend on other tests to form chains
- Easy to read assertions
- Injectable test data functionality
- Hooks before and after: Assembly, Class, Test
- Designed to avoid common pitfalls such as leaky test states
- Ability to view and interrogate metadata and results from various assembly/class/test context objects
Installation
dotnet add package TUnit --prerelease
Example test
[Test]
public async Task Test1()
{
var value = "Hello world!";
await Assert.That(value)
.Is.Not.Null
.And.Does.StartWith("H")
.And.Has.Count().EqualTo(12)
.And.Is.EqualTo("hello world!", StringComparison.InvariantCultureIgnoreCase);
}
or with more complex test orchestration needs
