[Question] Thread-safe ScenarioContext registration about specflow.autofac

[davidvesely]

Same problem here, we can't use Autofac and run tests in parallel when the FeatureContext or ScenarioContext is injected in the constructors. We need either to stop using Autofac, or remove the FeatureContext dependencies.
@finaruioana did you found any solution to the problem yet?

I really wish this plugin handled this stuff for you. The plugin should include an extension method so you could do something as simple as:

builder.RegisterSpecFlowTypes();

For ScenarioContext, the following is working for me in limited testing.

builder.Register(_ => ScenarioContext.Current).InstancePerDependency().ExternallyOwned();

There's likely still a race condition here, but this is the best I could do without really digging deep into both the source of this plugin and SpecFlow itself. :(

This plugin severely needs support for context injection. As is, it entirely replaces BoDi and thus breaks existing conventions.

Oh God I'm waiting since so long for this plugin to support context injection with AutoFac
@gasparnagy Is there any way you can make it possible in Specflow.AutoFac plugin to inject FeatureContext and ScenarioContext ?

Hi,

I am trying to enable running tests in parallel, but I cannot seem to make it work.

I had an AfterScenario hook which initially was verifying the static ScenarioContext.Current.TestError value.
All the DI registration is made using Specflow.Autofac package.

After upgrading NUnit to version 3.6.1, it threw an exception complaining about the use of this static ScenarioContext with a link to http://specflow.org/documentation/Parallel-Execution/

I made the update in my step class as in above link:
`
[Binding]
public class StepsWithScenarioContext
{
private readonly ScenarioContext scenarioContext;

public StepsWithScenarioContext(ScenarioContext scenarioContext)
{
    if (scenarioContext == null) throw new ArgumentNullException("scenarioContext");
    this.scenarioContext = scenarioContext;
}

[AfterScenario]
public void AfterScenario()
{
     if (_scenarioContext.TestError != null)  
            //do something
}

}
`

But now, the below exception is thrown:
Cannot resolve parameter 'TechTalk.SpecFlow.ScenarioContext scenarioContext'

I tried to find a way to register this scenario context into my DI, but wasn't able to find a way.
Did anyone else had this issue?
Is there a way to register the ScenarioContext into Specflow.Autofac registration?

Thank you and happy coding!

@finaruioana @davidvesely @wekempf Still no resolution,

Have you tried asking this question in new specflow respository issue tracking ?
