What it is?

This lib provide support objects and base classes for testing Hub, Hub<T>, IHubContext<T>, IHubContext<T, P>. For example preconfigured mocks and helpfull verify methods. There is also support for testing Hubs and IHubContexts with Entity Framework Core.

Which nuget version should I choose?

1. netcoreapp (2.1, 2,2, 3.0, 3,1) - 2.0.0
2. net5 - 5.0.0
3. net6.0 - 6.0.0
4. net7.0 - 7.0.0
5. net8.0 - 8.0.0

How to install

1. Using Visual Studio Nuget Package Manager

If you dont know how install nuget via Visual Studio see this: https://www.youtube.com/watch?v=jX5HlrerIos

SignalR.UnitTestingSupport.NUnit
SignalR.UnitTestingSupport.xUnit
SignalR.UnitTestingSupport.MSTest

2. Using Packet Manager Console

Install-Package SignalR.UnitTestingSupport.NUnit
Install-Package SignalR.UnitTestingSupport.xUnit
Install-Package SignalR.UnitTestingSupport.MSTest

3. Using .Net CLI

dotnet add package SignalR.UnitTestingSupport.NUnit
dotnet add package SignalR.UnitTestingSupport.xUnit
dotnet add package SignalR.UnitTestingSupport.MSTest

Troubleshooting!

Install NUnit3TestAdapter nuget for visual studio testing with NUnit in visual studio. https://www.nuget.org/packages/NUnit3TestAdapter/

Install xunit.runner.visualstudio nuget for visual studio testing with xUnit. https://www.nuget.org/packages/xunit.runner.visualstudio/

Install MSTest.TestAdapter nuget for visual studio testing with MSTest.
https://www.nuget.org/packages/MSTest.TestAdapter/

If your tests are not even detected, install Microsoft.Net.Test.Sdk nuget :)
https://www.nuget.org/packages/Microsoft.NET.Test.Sdk/

How to use

After you add nuget to your test project, SignalR_UnitTestingSupport is ready to use.

All IHubContext support classes are in SignalR_UnitTestingSupportCommon.IHubContextSupport namespace

For NUnit: All testing base classes are in SignalR_UnitTestingSupport.Hubs namespace

For xUnit: All testing base classes are in SignalR_UnitTestingSupportXUnit.Hubs namespace

For MSTest: All testing base classes are in SignalR_UnitTestingSupportMSTest.Hubs namespace

1) Base classes approach (Recommended)

Create test class for hub for example:

class ExampleHubTests {}

And then:

1. For testing Hub

class ExampleHubTests : HubUnitTestsBase {}

2. For testing Hub<T>

class ExampleHubTests : HubUnitTestsBase<T> {}

3. For testing Hub with EntityFrameworkCore

class ExampleHubTests : HubUnitTestsWithEF<TDbContext> {}

TDbContext is any class which inherit from Microsoft.EntityFrameworkCore.DbContext or DbContext itself.

4. For testing Hub<T> with EntityFrameworkCore

class ExampleHubTests : HubUnitTestsWithEF<T, TDbContext> {}

TDbContext is any class which inherit from Microsoft.EntityFrameworkCore.DbContext or DbContext itself.

5. For testing with IHubContext<THub> see this.

5. For testing with IHubContext<THub, TIHubResponses> see this.

2) Testing objects approach (Alternative, if you can't use base classes).

How use second approach. See this.
