Unable to run my specFlow code through Console

Hello,

I am beginner in SpecFlow. I am unable to run SpecFlow through console file.

    Hi Kiran,

    here you can see the required files for SpecFlow and NUnit integration.

    SpecFlow.NUnit is required to generate the correct code behind file for the execution engine to understand the tests properly.

    please can you add the required packages and let me know how you get on.

    P.S. if you have queries please add them to the general discussions section of the site, otherwise they may not be picked up in the same time frame because they may be missed. Better still, submit a support ticket :)

    Jordan Western Thanks for your quick reply. Going forward, I will post my questions in General Discussions section. 

    I have already installed the required plugins.

    Here's the list:

    Microsoft.NET.Test.Sdk - 16.11.0
    NUnit - 3.13.1
    NUnit.Console - 3.11.1
    NUnit.ConsoleRunner - 3.11.1
    NUnit3TestAdapter - 4.0.0
    SpecFlow - 3.9.22
    SpecFlow.NUnit - 3.9.22
    SpecFlow.Plus.LivingDocPlugin - 3.9.57
    SpecRun.Runner - 3.9.7

    Still facing an issue. 

    Errors, Failures and Warnings

    1) Error :
    NUnit.Engine.NUnitEngineException : The NUnit 3 driver encountered an error while executing reflected code.
    ----> System.InvalidCastException : Unable to cast transparent proxy to type 'System.Web.UI.ICallbackEventHandler'.
    --NUnitEngineException

    Kiran Kumar,

    You have a reference to SpecRun.Runner - 3.9.7 which is conflicting, this is my first observation.

    Do your tests execute from inside of Visual Studio? And are the code behind files using NUnit references? My concern is that they are being generated for the SpecFlow + Runner and not NUnit, but i can be sure because I can't see your project :)

    Can you please send me the command you are using to execute the tests from the command line?

    I will try and replicate it.

    Hi Kiran Kumar,

    Did you acknowledge my other suggestions? :)

    Do these execute from the IDE?

    Please check which implementation the code behind files are using. If you want to use NUnit you only need the SpecFlow.NUnit package.

    Jordan Western I have tried in all possible ways. My issue is not resolved yet. 

    I am trying to run my test case for specific category, can you please help on this.

    Because of the error message "An exception occurred while invoking executor 'executor://specrun/executorV3.9.7': Exception has been thrown by the target of an invocation.", I think you still have files from the SpecFlow+ Runner in your output directory. 

    Clean them and try again.

    Hi Andreas Willich you want me to un-install the plugin?

    If you want to use NUnit, yes, remove this NuGet package (that is the correct term here)

    Andreas Willich I have uninstalled SpecRun.Runner and ran through command line, it is still throwing an error. . Please check the details below

    Andreas Willich Do you have 5min time.. Shall we connect quickly and resolve the issue .

    Sorry, but we don't do 1:1 support. 

    About your errors:

    The last post is an exception in your code.

    > at legion_arena_automation.Settings.Base.AenaApp() in D:\automation\Settings\Base.cs:line 49

    There is the NullRefException happening. 

    The post before that is an NUnit error with no SpecFlow code executed. And I never saw this error before. Something is very strange with your NUnit setup.
