❔ E2E Test - Start MVC project

Hi,

im using a testing tool for E2E testing and wondered how to get a MVC project started so the tool can visit the URL of the application and do some stuff?
I call this in the constructor of the test class

        OtherProjRefNs.Program.CreateWebHostBuilder(null)
            .UseStartup<Startup>()
            .Build()
            .Start();

        OtherProjRefNs.Program.CreateWebHostBuilder(null)
            .UseStartup<Startup>()
            .Build()
            .Start();

        OtherProjRefNs.Program.CreateWebHostBuilder(null)
            .UseStartup<Startup>()
            .Build()
            .Start();

        OtherProjRefNs.Program.CreateWebHostBuilder(null)
            .UseStartup<Startup>()
            .Build()
            .Start();

but when I navigate to the URL within a browser after the

Start()

Start()

method, it says the page is not reachable. How can I start my MVC project?

show the actual full error

instead of

it says the page is not reachable.

what do you actually see

TeBeCo•3/30/23, 3:43 PM

a stack trace / a page / browser hang / etc ....

(add screen shots ... FOR NOW so we visualize)

I see this (first attachment) when I open the page
The network tab shows this (second attachment).
I dont see errors in the output console or somewhere else.

I reduced the call to

        OtherProjRefNs.Program.CreateWebHostBuilder(null)
            .UseStartup<Startup>()

        OtherProjRefNs.Program.CreateWebHostBuilder(null)
            .UseStartup<Startup>()

So it's going inside the ConfigureServicesConfigureServices and ConfigureConfigure method, but it's too fast! I think the server is not started somehow.. when I debug the MVC project, it starts up correctly.

Maybe the appsettings.json cannot be loaded, let's see I debug again

did you follow the docs for E2E ?

TeBeCo•3/30/23, 3:59 PM

are you speaking of using WebApplifactionFactory ?

TeBeCo•3/30/23, 3:59 PM

or you do actually run the app

TeBeCo•3/30/23, 3:59 PM

and test with like Playright or cypress ?

I followed the IntegrationTest docs, as there was no E2E docs. I already tried the WebApplicationFactory but with the same results. The issue might be in my understanding of how it works, as it does not startup the whole MVC project, but I thought it would.
We use Playwright in C# with XUnit. Unfortunately, there is no real documentation about that.
Our idea was that the test could do start/shutdown the whole MVC project, so we dont have to start and shutdown the MVC project separately before and after all tests.

can you share your github url project ?

TeBeCo•3/30/23, 5:49 PM

there's an issue in the code itself and/or your config

TeBeCo•3/30/23, 5:49 PM

and there's no way I'll ask all question one after the other it would take hours

TeBeCo•3/30/23, 5:49 PM

send repo link

TeBeCo•3/30/23, 6:03 PM

@Davaaron ?

TeBeCo•3/30/23, 6:03 PM

my guess is that you did not ran the E2E in fact

TeBeCo•3/30/23, 6:04 PM

or that you're relying on a file unrelated to test

TeBeCo•3/30/23, 6:04 PM

because that port is not the port from appsettings

TeBeCo•3/30/23, 6:04 PM

because by default there's no port in appsettings

TeBeCo•3/30/23, 6:04 PM

TLDR: send repo link

Was this issue resolved? If so, run

/close

/close

otherwise I will mark this as stale and this post will be archived until there is new activity.
