onScreenshot method never called during instrumented tests #200

Closed davidvavra closed 2 years ago

davidvavra commented 2 years ago

Hi, I'm trying to build a sample app for article about this library & screenshot testing.

When I run ./gradlew connectedDebugAndroidTest, the onScreenshot() method is never called.

Here is the code of the sample app: https://github.com/davidvavra/showkase-screenshot-tests

I'm not sure what's wrong, it works in my work app, but not in this sample app. I have double checked both implementations, but maybe I missed something. Can you help?

Hi David! I pulled your project and was able to find the root cause. You will need to add this line in your build.gradle files 

kaptAndroidTest "com.airbnb.android:showkase-processor:1.0.0-beta08"

You will also need to make sure that you add this activity in your AndroidManifest. This is needed by Compose but I'll try adding it to the library and hopefully that should avoid needing the user of the library from adding it separately. 

<activity
            android:name="androidx.activity.ComponentActivity" />
