How to use Extent Reports in parallel execution to print test logs

[sudgarre]

Hi All -

Background:

To give a brief context, we are using ExtentReports for our playwright tests with reqnroll & using DI to capture and show info/warning logs on the extentreport.

    <PackageReference Include="ExtentReports" Version="5.0.2" />
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.10.0" />
    <PackageReference Include="Reqnroll" Version="2.2.1" />
    <PackageReference Include="Reqnroll.Microsoft.Extensions.DependencyInjection" Version="2.2.1" />
    <PackageReference Include="Reqnroll.NUnit" Version="2.2.1" />
<PackageReference Include="NUnit3TestAdapter" Version="4.6.0" />
<PackageReference Include="NUnit" Version="4.2.2" />
<PackageReference Include="NUnit.Extension.DependencyInjection" Version="0.7.1" />

1. ExtentReport Test is initialised as below in Hooks class

public class Hooks
{
private readonly IExtentTestManager _extentTestManager;

        public Hooks(IExtentTestManager extentTestManager)
        {
            _extentTestManager = extentTestManager;
        }

[BeforeScenario]
public async Task BeforeScenario()
{
    var feature = _extentReports.CreateTest<Feature>(_featureContext.FeatureInfo.Title, _featureContext.FeatureInfo.Description);
    _extentTestManager.SetCurrentTest(feature);

    _scenario = feature.CreateNode<Scenario>($"{_scenarioContext.ScenarioInfo.Title}");
}

}

2. We have created below for setting up ExtentTestManager for DI

 public interface IExtentTestManager
 {
     ExtentTest GetCurrentTest();
     void SetCurrentTest(ExtentTest test);
     void WriteLine(string message);
     void WriteWarning(string message);
     void WriteError(string message);
     void WriteErrorWithException(string message = null, string errorTrace = null, Media media = null);
 }

 public class ExtentTestManager : IExtentTestManager
 {
     public static AsyncLocal<ExtentTest> _asyncLocalExtentTest = new AsyncLocal<ExtentTest>();

     public void SetCurrentTest(ExtentTest test)
     {
         Console.WriteLine($"SetCurrentTest called in thread: {Environment.CurrentManagedThreadId}");
         _asyncLocalExtentTest.Value = test;
     }

     public ExtentTest GetCurrentTest()
     {
         Console.WriteLine($"GetCurrentTest called in thread: {Environment.CurrentManagedThreadId}");
         return _asyncLocalExtentTest.Value;
     }
 }

3. Register ExtentTestManager in Startup.cs

public class Startup
{
    [ScenarioDependencies]
    public static IServiceCollection CreateServices()
    {
        var services = new ServiceCollection();

        services
            .AddScoped<IExtentTestManager, ExtentTestManager>();
       return services;
    }
}

4. Inject IExtentTestManager into Page Classes as below

public class LoginPage
{
    private readonly IExtentTestManager _extentTestManager;

    public LoginPage(IExtentTestManager extentTestManager)
    {
        _extentTestManager = extentTestManager;
    }

    public void PerformLogin(string username, string password)
    {
        var extentTest = _extentTestManager.GetCurrentTest();
        extentTest .Log(Status.Info,"Login page is displayed");
    }
}

In Step 4, extentTest value returns null.

Clarifications Needed:

We currently notice that ExtentTest thread and Nunit test thread run on different threads hence causing the issue, This happens even though we are using Before Scenario to initialize ExtentTest

How do we make sure if our test execution framework (e.g., NUnit here) runs scenario setup and execution on the same thread ?
