Data variable requiring MockMvc

[jochenberger]

Hi,

I'd like to add a data-driven test that checks the results for multiple requests to a spring-boot web app. The data that defines the iterations needs to be fetched via a request too, via an @Autowired MockMvc. However, at the time when the data pipe is resolved, the MockMvc field is apparently not yet initialized, so I get an NPE.
Am I doing something wrong or is this just not possible?

Thanks,
Jochen

What does the field you try to access look like?
I think if it is neither static nor @Shared, you should get a compile error when trying to access from a where block iirc.
If it is static I think auto-wiring is non-effective.
If it is @Shared you should also get an exception if you try to autowire except if you opted in to injecting into shared fields explicitly as there can be some quirks (see the JavaDoc of EnableSharedInjection class.

It's neither static nor @Shared:

    @Autowired
    private MockMvc mvc

Ah, I see. I'm not accessing mvc directly from the where block. I'm calling another method that uses the mvc.

Ah, ok, that's why you don't get a compile error, this is not detected.
So yeah, if you want to do that you probably have to enable shared field injection and make the field shared.
If that is possible in this case, see the JavaDoc I mentioned.

Thanks, that seems to work.
