ClassName Incorrect During AfterFeature

Mar 11, 2025 by ADMIN 40 views

Introduction

Reqnroll is a popular testing framework for .NET that provides a lot of features to make testing easier. However, like any other framework, it has its own set of limitations and bugs. In this article, we will discuss a specific issue that has been reported by users of Reqnroll, which is the incorrect value of TestContext.CurrentContext.Test.ClassName during the [AfterFeature] hook.

Reqnroll Version

The issue was first reported in Reqnroll version 2.1.1 and earlier. However, it was fixed in version 2.2.0 and higher.

Test Runner Information

The test runner used in this scenario is NUnit, with version 5.0.0.

.NET Implementation

The .NET implementation used in this scenario is .NET 8.0.

Test Execution Method

The test execution method used in this scenario is Visual Studio Test Explorer.

Issue Description

The value of TestContext.CurrentContext.Test.ClassName has a wrong value during the [AfterFeature] hook. In Reqnroll version 2.1.1 and earlier, it contained always the name of the active feature file. However, in version 2.2.0 and higher, it has the name of the next feature file during the [AfterFeature] hook. If there is no next feature, it has a generic name with "NUnitAssemblyHooks".

Steps to Reproduce

To reproduce this issue, follow these steps:

Check out the Quickstart branch from the Reqnroll GitHub repository.
Switch from MSTest to "Reqnroll.NUnit" Version="2.1.1" with "NUnit3TestAdapter" Version="5.0.0".
Make a copy of the feature file and rename both to FirstPriceCalculation.feature & SecondCalculation.feature.
Add the following Hooks file:

using NUnit.Framework;

namespace ReqnrollQuickstart.Specs.Hooks
{
    [Binding]
    internal class Hooks
    {
        private static readonly string logfile = @"c:\temp\log.txt";

        [BeforeFeature]
        public static void BeforeFeature()
        {
            File.AppendAllText(logfile, "BeforeFeature: " + TestContext.CurrentContext.Test.ClassName + Environment.NewLine);
        }

        [BeforeScenario]
        public static void BeforeScenario()
        {
            File.AppendAllText(logfile, "BeforeScenario: " + TestContext.CurrentContext.Test.ClassName + Environment.NewLine);
        }

        [AfterScenario]
        public static void AfterScenario()
        {
            File.AppendAllText(logfile, "AfterScenario: " + TestContext.CurrentContext.Test.ClassName + Environment.NewLine);
        }

        [AfterFeature]
        public static void AfterFeature()
        {
            File.AppendAllText(logfile, "AfterFeature: " + TestContext.CurrentContext.Test.ClassName + Environment.NewLine);
        }
    }
}

Run the tests.
The content of log.txt will be:

BeforeFeature: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature BeforeScenario: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature AfterScenario: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature BeforeScenario: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature AfterScenario: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature AfterFeature: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature BeforeFeature: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature BeforeScenario: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature AfterScenario: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature BeforeScenario: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature AfterScenario: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature AfterFeature: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature

Change from "Reqnroll.NUnit" Version="2.1.1" to "Reqnroll.NUnit" Version="2.2.0".
Run the tests again.
The content of log.txt will be:

BeforeFeature: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature BeforeScenario: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature AfterScenario: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature BeforeScenario: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature AfterScenario: ReqnrollQuickstart.Specs.Features.FirstPriceCalculationFeature AfterFeature: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature BeforeFeature: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature BeforeScenario: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature AfterScenario: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature BeforeScenario: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature AfterScenario: ReqnrollQuickstart.Specs.Features.SecondPriceCalculationFeature AfterFeature: ReqnrollQuickstart_Specs_NUnitAssemblyHooks

Conclusion

In conclusion, the value of TestContext.CurrentContext.Test.ClassName has a wrong value during the [AfterFeature] hook in Reqnroll version 2.2.0 and higher. This issue was fixed in version 2.1.1 and earlier, where it contained always the name of the active feature file. However, in version 2.2.0 and higher, it has the name of the next feature file during the [AfterFeature] hook. If there is no next feature, it has a generic name with "NUnitAssemblyHooks". This issue can be reproduced by following the steps outlined above.

Recommendations

To avoid this issue, it is recommended to use Reqnroll version 2.1.1 and earlier. If you are using Reqnroll version 2.2.0 and higher, you can use the following workaround:

Use the [AfterFeature] hook to log the name of the current feature file instead of the next feature file.
Use the [BeforeFeature] hook to log the name of the next feature file.

By following these recommendations, you can avoid the issue of incorrect TestContext.CurrentContext.Test.ClassName value during the [AfterFeature] hook in Reqnroll version 2.2.0 and higher.

Future Work

In the future, it would be great to see Reqnroll fix this issue and provide a more consistent behavior for the [AfterFeature] hook. This would make it easier for users to write tests and avoid issues like this one.
