NUnit.Extensions.Helpers

Helpers to generate NUnit tests

This is not an official NUnit package.

Install

Add the NuGet package NUnit.Extensions.Helpers to any project supporting .NET Standard 2.0 or higher.

> dotnet add package NUnit.Extensions.Helpers

Information

Currently the generated source requires Moq and Shouldly.

Usage

Constructor parameter null tests

Use the GenerateConstructorParameterNullTests attribute to define the SUT (class which should be tested) to generate constructor parameter tests for.

[GenerateConstructorParameterNullTests(typeof(Document))]
internal partial class DocumentTests
{
    [Test]
    public void Test1()
    {
        Assert.Pass();
    }
}

If the SUT looks like

public class Document
{
    private Stream _stream;
    private IFileTester _fileTester;
    private IOtherFilter _filter;

    public Document(Stream myStream, IFileTester fileTester, IOtherFilter filter)
    {
        _stream = myStream ?? throw new ArgumentNullException(nameof(myStream));
        _fileTester = fileTester ?? throw new ArgumentNullException(nameof(fileTester));
        _filter = filter ?? throw new ArgumentNullException(nameof(filter));
    }
}

following code will be generated:

partial class DocumentTests
{
    [Test]
    public void Throws_Exception_When_MyStream_Is_Null()
    {
        Action action = () => new Document(null, null, null);
        action.ShouldThrow<ArgumentNullException>().ParamName.Should().Be("myStream");
    }

    [Test]
    public void Throws_Exception_When_FileTester_Is_Null()
    {
        Action action = () => new Document(Mock.Of<System.IO.Stream>(), null, null);
        action.ShouldThrow<ArgumentNullException>().ParamName.Should().Be("fileTester");
    }

    [Test]
    public void Throws_Exception_When_Filter_Is_Null()
    {
        Action action = () => new Document(Mock.Of<System.IO.Stream>(), Mock.Of<Sample.IFileTester>(), null);
        action.ShouldThrow<ArgumentNullException>().ParamName.Should().Be("filter");
    }
}

Options

It's possible to generate a nested class with the AsNestedClass argument.

[GenerateConstructorParameterNullTests(typeof(Document), AsNestedClass = true)]
internal partial class TestWithNested
{
}

Web service tests

Use the WebServiceTester helper class. This class reads the OpenApi documentation and can execute arbitary tests.

[Test]
public async Task TestEndpointSecurity()
{
    var tester = new WebServiceTester("swagger.json");

    await tester.VerifySecuredEndpointsRequiresAuthentication(httpClient, CancellationToken.None);
}
