correct it just works

and all you did was

apply plugin: "kotlin-android-extensions"

? We're having a bit of trouble with them being

null

in Espresso 😕

I think the only other thing was to add

src/androidTest/kotlin

src set. what is the context of your consumption of the synthetic properties?

Checkout https://github.com/JoachimR/ThePokerGuys i made some espresso Tests there too

@trevjones we're using an

ActivityTestRule

to launch an activity, and then we're trying to call the synthetic view extensions on it. We don't use

src/X/kotlin

dirs, all of our Kotlin source is in the

src/X/java

folders, including for tests

Then i misunderstood what you meant sorry

I don’t think that srcSets would be related at all, just pointing out that it is the only other kotlin androidTest config change I have in gradle. In all the cases that I use the synthetic properties I am doing it on views that are inflated directly in my test case. The test case does use an activity test rule but only so I have a normal app compat activity to use as context for inflation. This all in concert with the facebook screenshot testing api’s. All that said if you can get a reference to the activity the synthetic properties should work against it assuming the activity has had onCreate called. My guess is that there is some misunderstanding in the way the activity test rules work? Let me find a blog post that goes into detail about how things changed depending on the activity rule params.

it's weird because finding the views by ID does work, the synthetic views are just null apparently

are you doing like

activity.some_view_id

or what are the specifics?

yes, that's what we're trying to do. But doing

activity.findViewById(R.id.some_view_id) as MyViewType

works fine, so it's confusing why the synthetic bindings don't find it

what import are you using for the synthetics?

@trevjones sorry for the delay, didn't have time to work on this and had to jump to some other stuff. Hopefully you're still willing to help. 😛 The import is

import kotlinx.android.synthetic.main.fragment_add_venue_info.*

. Same import that we use in the actual classes and it works there I also tried running it just now, whatever issue we were having before (I was trying it out on my coworker's machine) is manifesting differently for me. We get a build error, with

Unresolved reference: fragment_add_venue_info

at the line with the import for the synthetic 😕
